Description
Technical field
A kind of pipe fitting is the utility model is related to, a kind of high intensity PE bellowss is specifically related to, belongs to plastic pipe technology
Field.
Background technology
HDPE double-wall corrugated pipes, abbreviation PE bellowss, the beginning of the eighties succeed in developing first in Germany.By the hair of more than ten years
Open up and perfect, via single Cultivar development to complete product line.In production technology and use technology very
It is ripe.Due to its excellent performance and the cost of relatively economical, have been obtained for greatly promoting in developed countries such as America and Europes and
Using.
Double-wall corrugated pipe is a kind of novel light tubing using high density polyethylene (HDPE) as raw material, has in light weight, resistance to height
The features such as pressure, good toughness, construction are fast, long lifespan, its excellent structural pipe wall design, compared with the tubing of other structures, cost
Substantially reduce.And due to easy to connect, reliable, at home and abroad it is used widely, it is a large amount of to substitute pipe of concretes and cast iron pipe.
At present, high intensity HDPE double-wall corrugated pipes are just increasingly being applied to build, communicated, agriculture with its excellent performance
The association areas such as industry.Existing HDPE double-wall corrugated pipes bulk strength is poor, is squeezed and easily produces rupture, and raised director
Easily abrasion, greatly reduces service life after long use.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high intensity PE bellowss for above-mentioned prior art,
Its is simple in construction, and bulk strength is high, substantially increases the pressure-resistant performance of pipe fitting, and high spot is not likely to produce abrasion, greatly improves
The service life of pipe fitting.
The technical scheme in the invention for solving the above technical problem is：A kind of high intensity PE bellowss, it includes interior
Straight pipe, the interior straight pipe include interior substrate layer and outer flexible layer, multi-ring annular groove are provided with the interior substrate layer outer wall,
Ring like steel wire is provided with the annular groove, the outer flexible layer is coated on outside ring like steel wire, is set on the outer flexible layer outer wall
Spiral salient is equipped with, setting is fluted on the outside of the spiral salient, and wear rib is equipped with the groove, the spiral salient
Reinforcement bed course is provided with gap.
It is bonded together between the interior substrate layer and outer flexible layer using glue.
Compared with prior art, the utility model has the advantage of：
A kind of high intensity PE bellowss of the utility model, it is provided with it between interior substrate layer of straight pipe and outer flexible layer
Ring like steel wire, substantially increase the bulk strength of pipe fitting；Wear rib is provided with the outside of spiral salient, projection can be greatly improved
Anti-wear performance, substantially increase the service life of pipe fitting；It is outer flexible layer on the outside of interior substrate layer, can exists when pipe fitting is squeezed
Certain buffering, it can effectively prevent pipe fitting extruding from producing rupture, improve the pressure-resistant performance of pipe fitting；It is provided between spiral salient
Strengthen bed course, on the one hand can increase the intensity of spiral salient, outer flexible layer on the other hand can be protected against damages.
