Another object of the invention is to provide improved shock energy absorbing tube restraints to create that in a simple manner with high energy tubes with different energy levels are applicable.

Finally, another object of the invention is to reduce impact energy to create absorbent, pipe restraint devices with which the lateral vibrations a broken pipe can be reduced.

Other objects, objects and advantages of the present invention will become based on a detailed description together with the accompanying drawings explained below.

The solution to the above-mentioned objects occurs in one embodiment an impact energy absorbing pipe restraint device according to the invention Use of a laminated tape formed from strips of material is, which has the property of being greatly elongated in the plastic state and is thereby able to absorb the impact energy of a broken high-energy pipe absorb in at least one direction. The laminated band is designed in this way and arranged that it is in Unfangsrich device at least a part of the high-energy tube extends around it, having an arcuate portion formed thereon, which is arranged in the vicinity and at a predetermined distance from the high-energy pipe is to the movement of the broken high energy tube towards the arch-shaped part to catch. Furthermore, anchoring devices are arranged at the ends of the lay-up tape provided to anchor the laminated tape to a support structure.

For the purposes of the invention, a “laminated band” is intended to mean a plurality be understood by strips or slats, which at each of their ends with a common plate or block are connected, but which have a considerable Proportion of their length are not interconnected.

Another embodiment of an impact energy absorbing tube restraint according to the present invention is characterized by a retaining or collecting pipe, which is arranged in the vicinity of the high-energy pipe transversely to its longitudinal axis in such a way that that upon impact of the broken high-energy tube on the collecting tube this is pressed in, with a plastic deformation and thus an absorption the energy of the high-energy pipe takes place and a recess in the collecting pipe which contributes to the lateral movement of the broken high energy tube to limit.

Particularly advantageous embodiments of the subject matter of the invention are shown in the accompanying drawings.

It should be understood, however, that the invention does not apply to the following Limited execution examples explained with reference to the drawings.

FIG. 6 shows the pipe retaining device according to FIG. 5 in a side view.

In Fig. 1 is an embodiment of an impact energy absorbing Pipe restraint device according to the present invention, indicated generally at 10, arranged in the vicinity of a high-energy pipe 12. In general, the high energy pipe 12 an outer concentric heat insulating jacket 14, which the inner, stainless steel tube 16 carrying a high energy fluid, surrounds.

It is understood, however, that the tube 12 has such a jacket, as desired, may or may not have. The pipe restraint device shown 10 is particularly useful for absorbing the impact energy of a high energy pipe from of a type usable, for example, in nuclear power plants, wherein the high energy tube communicates a pressurized fluid.

The pipe restraint device 10 has a laminated band 17, which is composed of a plurality of strips of a ductile material which means that each strip has the property of being considerably in its plastic state to extend. Preferably the strips are made of annealed stainless steel, as it is known under the type designation 304, for example. This attribute of the material forming the laminated belt 17 is essential to achieve the required Ability to achieve energy absorption of the laminated tape 17. Farther is made by the formation of the band 17 from individual lamellae or strips Ability to absorb energy of the tape is greatly increased since the plastic deformation of the belt takes place under membrane action (tension), creating bending stresses largely avoided.

The individual strips or lamellas of the laminated tape 17 are brought into the desired shape suitable for retention, for example, as shown in Fig. 1, U-shaped, and for example by connecting clips held together, while their ends 16 and 18 each with the ends of a pair of plates or blocks 20 and 22, preferably by welding with a tungsten arc welder get connected. The specific number of used in the laminated tape 17 Strips, such as the width of the laminated tape 17, may vary depending on the size of dz amount of impact energy to be absorbed. Preferably the number is Strips or sipes in the laminated tape 17 ranging from about 2 to about 100. Likewise, the width of the strips or lamellas is preferably in the range from 1.27 cm to about 38.1 cm (0.5 "to 15") panels 20 and 22 are preferred also made from annealed frost-free steel of type 304 and have each Hole punch 24 and 26 for receiving a pin or bolt.

The holes 24 and 26 are formed so that pins 28 and 30 can be passed through them, the ends of which can be rotated into a pair of rectangular trained apex or fork-shaped tabs 32 and 34 are mounted. The tabs 32 and 34 have holes 33A and 33B, as well as 35A and 35B, for the respective rotatable Receipt of the pins 28 and 30. Optionally, each of the tabs can by arranged on her End plates are reinforced.

Preferably, at the ends of the pins 28 and 30, which consist of the forked tabs 32 and 34 protrude, snap rings 4 and 44B and 46A and 46B to prevent pins 28 and 39 from dislodging tabs 32 and 34 slide out In an alternative, not shown, instead of the pencils 28 and 30 and their snap rings 44A and 44B and 46A and 46B, respectively, use bolts the ends of which are threaded for connection to a pair of nuts are.

Before assembling the pins 28 and 30, the tabs 32 and 34 are, preferably with a support device 48 of conventional design connected.

With restraint devices for lines up to about 30.5 cm (12 inch) diameter, it is generally advantageous to use spherical bearings 40 and 42, which are inserted into holes 24 and 26 with a press fit and with pins 28 and 30 are connected, whereas with thicker lines such bearings are less desirable are. By using these spherical bearings, there is also a rotary movement of blocks 20 and 22 in a direction perpendicular to the axes of pins 28 and 22 30 enabled. When spherical bearings are used in this way it is advantageous to sleeves 36A and 36B, as well as 38A and 38, suitably formed from steel tubing 38B on pins 28 and 30 to provide a centered spacer for the Plate 20 and 22 with respect to the side walls of tabs 32 and 34 to reach and in this way movement of the plates 20 and 22 in the direction of the pins 28 and 30 on the side walls of the tabs 32 and 34 to prevent.

One end of the sleeves 36A and 36B abuts the inner side walls of tabs 32 and the other end of sleeves 36A and 36B abut against the spherical Bearing 40. In the same way, one end of the sleeves 38A and 38B abuts against the inner sidewalls of tab 34 and the other end of sleeves 38A and 38B abuts against the spherical bearing 42.

In an alternative embodiment, the tabs are 32 and 34 rotated 900 so that the axes of pins 28 and 30 passing through the holes are passed through the tabs, run parallel to the tube 12. In this case are the holes 24 and 26 in the blocks 20 and 22 in one opposite the above-described embodiment by 900 rotated position By the relatively narrow width of the laminated edge # 17, 1 in contrast to the large one Width of the arc used in the known pipe restraint devices with the self-balancing rotatable pins 28 and 30 the advantage becomes achieves that the differential stress across the width of the laminated Band / caused by oblique pipe joints, which make initial contact of the high energy tube 12 with one end of the interior of the laminated tape 17, can be greatly reduced. Furthermore, as already mentioned, enables the use a multitude of strips or lamellas absorb the impact energy Meabranffekt (tension), whereby the bending effects, which from the allowable stress must be deducted, are greatly reduced.

As shown in Fig. 1, the laminated belt 17 is formed in a lo-shape and has an arcuate portion 49, with an apex 80 and leg portions 82 and 84 on. The arched part 49 of the U is next to the high energy tube 12 in spaced a predetermined distance to prevent upward movement during breaking of the pipe in the direction of the arrow. This arrangement of the laminated Belt 17 at a certain distance, as well as the possibility of rotating the Tape in relation to tabs 32 and 34, ensures that during the periods in which no pipe breakage takes place, thermal and seismic displacements of the high-energy pipe 12 are not inadvertently hindered. Farther the lamination of the belt according to the present invention has some effect Flexibility, which allows a small distance between the laminated tape 17 and the high energy tube 12 allows without the normal tube movement in unintentional Way is hindered. The small distance in the transverse direction reduces the distance, which a broken pipe can move back before it is caught. This in turn reduces the on the support device 48 on which the restraint device is attached, applied force. For example, it is found in practice been that depending on the Geometry of the piping system the distance between the apex 80 of the laminated tape 17 and the insulating The jacket 14 of the high energy tube 12 can preferably be approximately 10.16 cm (4 inches), while the shortest distance between legs 82 and 84 of the laminated tape 17 and the insulating jacket 14 of the high-energy pipe 12 in the range of about 0.16 can range from 1/16 to 1/2 inch (cm to 1.27 cm).

It will be understood that the arcuate portion 49 are so arranged can that it stops the movement of the high-energy tube 12 in any direction and that more than one laminated tape 17 can be used to provide an all-round effect To achieve restraint (see Figs. 3 and 4). Furthermore, are preferred the ends 16 and 18 of the belt 17 connected to separate plates, which in the 1 and 2 shown manner with two tabs are connected. The ends 16 and 18 can, however, also be connected to a single plate which is attached to is anchored in a single tab.

It has been found to be particularly advantageous for the ends of the tape to the plates 20 and 22 to be welded.

To accomplish this, ends 16 and 18 are the laminated ribbon 17 widened so that these ends are wider than the body of the strap 17. The wider ends 16 and 18 thus form welded parts 37 and 39 of sufficient strength, between ends 16 and 18 and plates 20 and 22, causing interference to them can be avoided and thereby an either elastic or at most slightly plastic Deformation of the weldments 37 and 3 becomes possible. It was found that such Conditions occur when the width of the ends 16 and 18 of the laminated ribbon 17 1.5 sal is as large as the width of the body of the laminated ribbon 17. Up this way, under the action of a shock, the entire laminated tape becomes 17 plastically deformed and the welding parts 37 and 39 are slightly plastic.

The majority of the welding parts 37 and are advantageously located 39 and the rotatable anchoring parts in the elastic state, eliminating the need there is no need to subject the anchoring devices to strict quality control, the would be required if the anchoring devices in a rigid manner with the laminated tape 17 would be connected.

It should be noted that FIGS. 3, 4, 5 and 6 are the same Parts are given the same reference numerals. However, in Figs. 3, 4, 5 and 6 letters are used to distinguish the parts of each figure from one another For example, the restraint device labeled "10" in Figures 1 and 2 is in Figs. 3, 4, 5 and 6 with 10A, 10B and

lOC called.

In the embodiment of Figure 3 there is a pair of pipe restraints IOA and IOB, of the type shown in FIGS. 1 and 2, together with a collecting tube 50 used to achieve an all-round restraint device.

The pipe restraint devices IOA and lOB are made of laminated tapes 17A and 17B which have arcuate portions 49A and 49B, respectively. The catch straps 17A and 17B are at angles of about 450 to the transverse axis of a high energy pipe 52 arranged on both sides of the tube in order to prevent the high-energy tube from breaking 52 halt its movement towards the top and sides, and the collection tube 50 is arranged below the high-energy pipe 52 in order to prevent the high-energy pipe from breaking to stop its movement downwards. In this way it becomes all-round Pipe restraint reached.

The ends 16A and 18A, and 16B and 18B of the laminated ribbons 17A and 17B are elastic with fork-shaped tabs 32A and 34A and 32B and 34B, respectively, in FIG in a manner similar to that shown in FIGS. 1 and 2, connected. Preferably, however the tabs 32A and 34A, as well as 32b and 341 are each welded to sockets 53 and 54, which is formed in one piece with a support plate 55 and via bolt connections n are connected to a base plate 56 which is embedded or in the concrete floors is welded to a protective wall eder like. In addition, the tabs 32A and 34A and 32B and 34B, in a manner not shown, have riansches around them directly over bolts with the Connect concrete floor. In advantageous In this way, leaves 58 can be placed beneath the support plate carrying the pedestals 55 be arranged to adjust the position of the laminated bands bands 17A and 17B, as well as the collecting tube 50 in relation to the high-energy tube 52.

The embodiment made up of two bands and the collection tube 50 according to FIGS. 3 and 4 enables a uniform pipe tick hold over an angle of 3600 around the high-energy pipe 52. A pipe restraint that acts on all sides can however, they can also be built entirely from ribbons.

However, it has been found that it can be used to build an all-round acting pipe retaining device is advantageous, the collecting pipe 50 for absorbing the impact energy of a broken high energy tube 52 moving downward to use. Furthermore, the collecting tube 50 can also be used alone or together used with other pipe parts to prevent the movement of a broken high energy pipe stopping in any direction, but stopping it is especially beneficial the movement of a high energy pipe in the downward direction.

The collecting tube 50, which is made of carbon steel or stainless steel can consist of one or more straight or curved sections may be composed and generally has a diameter of about 3.8 to 91.4 cm (1.5 to 36 inches), depending on the diameter of the high energy tube 52 and of the energy level within it, and it is generally at a distance located between about 0.6 cm (0.25 ") to 12.7 cm (5") from the high energy tube 52. Preferably, the ends 62 and 64 of the collection tube 50 are free and the collection tube 50 is hollow, so that the impact energy of the high energy tube 52 by pressing in the Collection tube 50 is absorbed.

In order to keep the deformation of the high-energy pipe 52 low and the Energy absorption primarily on the collection tube 50 to judge the wall thickness of the collecting tube 50 should be less than 90 X the wall thickness of the high-energy tube 52.

It is also advantageous if the Wa ## of the collecting tube 50 is larger than about 0.25 cm (0.1 inch). It has also been shown that the cheap Selection of the pipe diameter ratios to reduce the deformation of the high-energy pipe 52 and mainly contributes to directing the energy absorption towards the collection tube 50. Preferably, the ratio of the diameter of the high energy tube 52 to Diameter of the collecting tube 50 in the range from 3: 1 to 1: 3.

Only as an example is given an embodiment with a Collection tube greater than 50.8 cm (20 inches) in length, diameter of 25.4 cm (10 inches) and a wall thickness of 1.51 cm (0.593 inches), which in the sense of of the present invention can be used to capture a high energy pipe 8.38 cm to 76.2 cm (3.3 to 30 inches) in diameter and wall thickness 1.67 cm (0.659 inch) The collecting tube 50 is anchored on a base 66 (see Fig. Fig. 4) and with this at points between its free ends 62 and 64 with the help connected by U-shaped bolts 68 and 70, allowing free lifting of the ends the collecting tube is made possible.

Other connecting means, for example passed through the pipe Bolts or welded connections at one or more points are possible Base 66 is connected to a supporting base plate 55, for example by welding, and connected to the base plate 56 via bolts.

An advantage of this arrangement described above is that during the impact of the high-energy tube 52 on the collecting tube 50, the free Ends 62 and 64 at about 5 to 30 ° with respect to the longitudinal axis of the collecting tube 50 move upwards, so that during the depression of the collecting tube 50 a U-shaped Recess 52 is formed in the collecting tube 50. (see dash-dotted representation of the collecting tube 50 in Fig. 3) Preferably, the length of the collecting tube should 50 about two to five times its diameter, so that at the Push the recess 72 partially surrounds the broken high energy tube 52 and thereby helps to stop his lateral movements.

In Fig. 5 is a further embodiment of an all-round acting Pipe restraint shown. A single pipe restraint IOC has a laminated band 17c for stopping the upward movement, and it acts together with a pair of collecting tubes 50A and 50B, the ends 62A and 62B of which are perpendicular are cut to their axes. The collecting tubes 50A and 50B are rectangular to each other below the high-energy pipe 52 parallel to a transverse axis of the high-energy pipe arranged so that they are V-shaped to each other and facing sideways and downwards Catch movements of the broken high-energy tube 52.

Laminated belt 17C is movable with tabs 32C and 34C, in the manner as described with reference to FIG. 1 connected.

The tabs 32C and 34C are integral with a supporting sock plate 55A connected. The tubes 50A and 50B are provided with base supports 74 and 76 (see Fig also Fig. 6) via U-shaped bolts 68A and 70A and 68B and 70B or via others already described connecting means connected. The supporting base plate 55A is bolted to a base plate 56A embedded in the concrete floor or via a welded connection with a steel structure connected to sheets 58A may be placed under the supporting base plate for adjustment the location of the laminated tape 179 and the collection tubes 50A and 50B with respect to FIG the high energy tube 52.

In operation, the pipe restraint device 10 according to FIGS 1 and 2 the impact energy of the high energy tube 12 as it moves upwards and hits the arcuate portion 49 of the laminated tape 17. The ribbon 17 deforms plastically, experiencing a considerable elongation and its lamellar construction is used to reduce the tension to the Broken tube 12 to enlarge. This way it will continue to move upwards of the broken pipe 12 and damage to the entire system in this area prevented.

In the same way, the movement of a broken pipe will be with the all-round effective pipe restraint devices according to FIGS. 3 and 4, as well as 5 and 6 reached. In the embodiment of FIGS. 3 and 4, the lateral and the upward movement of the broken high energy tube 52 through the laminated Bands 17A and 17B are caught and the downward movement of the broken tube 52 is held up by the transverse collection tube 52, which the Impact energy of the broken high-energy tube 52 by pressing and training a recess 72 absorbed, the recess 72 contributing to the lateral Movement of the broken high-energy tube 52 to be stopped. In the embodiment 5 and 6, the lateral and downward movement of the broken High energy tube 52 held up by the collection tubes 50A and 50B, which in the right Angle to each other are arranged and the upward movement of the high energy pipe 52 is stopped by the laminated tape 17C.

It will be understood by those skilled in the art that further modifications of the illustrated embodiments of the invention are possible without the basic idea the invention as expressed in the description and claims, to leave. Blank page
