Description

A kind of HDPE double-wall corrugated pipes

Technical field

The technical field of pipeline is the utility model is related to, especially a kind of HDPE double-wall corrugated pipes.

Background technology

High density polyethylene (HDPE) (HDPE) double-wall corrugated pipe, it is that one kind has cyclic structure outer wall in known technical field With the novel tube of smooth internal walls.Density polyethylene (HDPE) has excellent chemical stability, ageing-resistant and environmental stress resistance The performance of cracking.It is that the HDPE double-wall corrugated pipes that raw material are produced belong to flexible pipe by it.It mainly has：Critical external compressive resistance energy Power is strong, and under the situation condition of condition difference, its advantage is more obvious, and the coefficient of friction resistance is small, and flow is big, low-temperature resistant and shock resistant performance, uses Long lifespan.Existing double-wall corrugated pipe under medium and small caliber size relatively be applicable, under the occasion of Large Diameter Pipeline, its enabling capabilities and Intensity is still less than metal pipe material, therefore needs that a kind of can to combine traditional HDPE double-wall corrugated pipes advantage and metal pipe material excellent The tubing of point.

Utility model content

The technical problems to be solved in the utility model is：Overcome above mentioned problem, there is provided a kind of HDPE double-wall corrugated pipes, can The advantages of the advantages of making full use of the double-wall corrugated pipe of traditional HDPE material and high metal tube intensity, and can adapt to the chi of Large Diameter Pipeline Very little requirement.

Technical scheme is used by the utility model solves its technical problem：A kind of HDPE double-wall corrugated pipes, have by Outer HDPE outer layers, cushion rubber layer, ABS separation layers, the stainless steel supporting layer set gradually in, the outside of the HDPE outer layers Be provided with several cross sections in the first raised of circular arc in yi word pattern, the outer surface of the cushion rubber layer be provided with it is first convex One-to-one second projection, and the described second raised inner surface for being embedded in HDPE outer layers are played, in the HDPE double-walleds ripple The side of line pipe is equipped with welding tube head, and the end face of the welding tube head is provided with ring-shaped groove, and the cushion rubber layer, ABS The end face of separation layer is embedded in ring-shaped groove, and the close outer surface side of the end face of the HDPE outer layers props up welding tube head End face, the close inner surface side of the end face of the HDPE outer layers is embedded in ring-shaped groove, the stainless steel supporting layer The close outer surface side of end face is embedded in ring-shaped groove, and the inner surface side of the end face of the stainless steel supporting layer props up The end face of tube head is welded, non-contact one end of the welding tube head and HDPE double-wall corrugated pipes is provided with annular solder holding groove.

Further, as a kind of specific package assembly mode, the end face that tube head is welded described in the utility model has There is insertion seam, and the insertion seam is embedded in stainless steel supporting layer.

Further, it is contemplated that specific connected mode, tube head and stainless steel supporting layer are welded described in the utility model Between be spirally connected fixation.

Further, it is contemplated that the sealing after construction, the utility model connect welding tube head and the HDPE outer layers Adhesive-layer is provided with joint close gap.

The beneficial effects of the utility model are：The utility model is simple in construction, in the architecture basics of traditional double wall bellows Upper increase cushion rubber layer, absorption vibrations and the crush resistance energy of product can be improved, increase is flexible, while ABS separation layer masters Play a part of insulation, isolation steam, further improve the whole service life of product, stainless steel supporting layer is similar to tradition Steel pipe, but due to the lamination layer structure that its outer layer is set, stainless steel supporting layer can do thin, meet the feelings of use condition Cost-effective under condition, this product heavy construction that is particularly suitable for use in uses in the case where execution conditions are severe, improves making for product With the life-span, the frequency safeguarded, great practical value are effectively reduced.
