Hebei manufacturer HDPE Double wall corrugated pipe polyethylene corrugated pipe municipal engineering drainage and sewage pipe manufacture

HDPE large diameter bellows
1、 Introduction to HDPE large diameter bellows
HDPE large-diameter corrugated pipe, HDPE corrugated pipe and large-diameter double wall corrugated pipe are often used for drainage, so they are also called "drainage pipe", The inner wall of large-diameter bellows is smooth, the outer wall is corrugated, and the inner and outer walls are hollow annular structure
The standard length is 6m
It can also be produced according to the length required by users
It is mainly used for expressways, municipal roads, bridges, radio and television, posts and telecommunications and telecommunications

2、 Properties of HDPE large diameter bellows

Project	physical properties
flat experiment	resist the load when it is pressed vertically to 50% of the original outer diameter, and the sample will not crack or layer
ring stiffness test kn / M & sup2;	≥ four
drop hammer impact test	TIR≤ ten
dichloromethane impregnation	there is no separation between the inner and outer surfaces, and the surface change is not greater than L
oven test	no delamination and cracking TR = "valtd" width>
≥ 0 6Mpa
