In order to avoid the adhesive portion between recombiner unit divides because of longitudinal power being pressed onto on tubing, such scheme is preferred, and the inside and outside wall in recombiner unit side all convexes to form semi-arched clinch, the inside and outside wall of recombiner unit opposite side the most horizontal-extending formation adhesive portion；The semi-arched clinch of recombiner unit is taken in the adhesive portion of adjacent recombiner unit and is fixed by viscose glue.
Such scheme is preferred, a length of 15-25mm of described semi-arched clinch.
Another implementation of the present utility model is as follows:
Steel plastic compount internally finned tube, including cylindrical tubing matrix, described cylindrical tubing matrix includes inner and outer wall, is formed with the hollow form fin of spiral on the outer wall, is provided with vertical muscle, is embedded with steel rib at vertical muscle in the cavity of this hollow form fin.
Such scheme is preferred, and described steel rib is perpendicular to the inside and outside wall of cylindrical tubing matrix.
Such scheme is preferred, and described hollow form fin is arcuate structure, and its rise is 20-120mm.
Such scheme is preferred, and described vertical muscle divides equally hollow form fin, and vertical muscle is contour with steel rib.
Compared with prior art, this utility model has the advantage that
1, in hollow form fin, it is provided with vertical muscle, and is embedded with steel rib at vertical muscle, not only increase the anti-pressure ability of hollow form fin, greatly improve the ring stiffness of tubing simultaneously；Additionally steel rib is coated in vertical muscle completely, will not offset, and stability is high, and steel rib will not contact with pumped (conveying) medium, and etching problem will not occur.
2, the bonding location between adjacent recombiner unit is horizontal direction so that tubing is when by weight, and bonding location will not occur problem of Cracking, also improves the hot strength of bonding location, extends the service life of drain pipe.
3, the structure of this steel plastic compount internally finned tube, it is higher that it produces operability, and improve the bulk strength of pipeline, extend the service life of product.

Detailed description of the invention
Embodiment 1
This utility model is a kind of steel plastic compount internally finned tube, as it is shown in figure 1, include cylindrical tubing matrix 1, described cylindrical tubing matrix 1 is mainly made up of spiral winding melting adhered multiple recombiner units 2.
Described recombiner unit 2 includes inner and outer wall, is formed with the hollow form fin 3 of spiral on the outer wall, is provided with vertical muscle 4 in the cavity of this hollow form fin 3, is embedded with steel rib 5 at vertical muscle 4.Hollow form fin 3 on each recombiner unit 2 can be 1, it is also possible to for multiple, is 1 in the preferred embodiment.As shown in the end view drawing of Fig. 2, described steel rib 5 is perpendicular to the inside and outside wall of cylindrical tubing matrix 1, and such steel rib 5 can be that tubing provides maximum ring stiffness.
Described hollow form fin 3 is arcuate structure, and so when tubing pressurized, what pressure can be mild is excessive on the inside and outside wall of tubing, improves the anti-pressure ability of tubing.The rise of hollow form fin 3 determines the excessive speed on the inside and outside wall of tubing that is stressed, and the compressive strength of hollow form fin 3, so the rise of hollow form fin 3 is extremely important, in the preferred embodiment, the rise of hollow form fin 3 is 20-120mm, in this height section, the comprcssive strength of tubing and ring stiffness are maximum.As shown in the end view drawing of Fig. 2, described vertical muscle 4 divides equally hollow form fin 3, i.e. indulge muscle 4 contour with the rise of hollow form fin 3, vertical muscle 4 can play the effect improving hollow form fin 3 comprcssive strength, indulge muscle 4 in the preferred embodiment contour with steel rib 5, namely steel rib 5 is contour with the rise of hollow form fin 3.
The inside and outside wall in recombiner unit 2 side all convexes to form semi-arched clinch 6, the inside and outside wall of recombiner unit 2 opposite side the most horizontal-extending formation adhesive portion 7；The semi-arched clinch 6 of recombiner unit 2 is taken in the adhesive portion 7 of adjacent recombiner unit 2 and is fixed by viscose glue 8, the bonding location of horizontal direction, compares the bonding external of vertical direction, and its anti-pressure ability is higher, namely more difficult because of pressurized cracking.The a length of 15-25mm of described semi-arched clinch 6, namely the bonding length of adjacent recombiner unit 2, such bonding location and bonding length are the most easy to crack when pressurized.
Embodiment 2
The present embodiment is as different from Example 1: the cylindrical tubing matrix 1 of steel plastic compount internally finned tube is one-body molded, and other are the most identical.As shown in Figure 3,4, described cylindrical tubing matrix 1 includes inner and outer wall, is formed with the hollow form fin 3 of spiral on the outer wall, is provided with vertical muscle 4 in the cavity of this hollow form fin 3, is embedded with steel rib 5 at vertical muscle 4.Described steel rib 5 is perpendicular to the inside and outside wall of cylindrical tubing matrix 1；Described hollow form fin 3 is arcuate structure, and its rise is 20-120mm；Described vertical muscle 4 divides equally hollow form fin 3, and vertical muscle 4 is contour with steel rib 5.Such design, it is to avoid the stretching problem of abutting edge between recombiner unit 2 in embodiment 1.
