The main performance of HDPE double-wall corrugated pipe is reflected in the ring stiffness, which is the S1 and S2 mentioned in the title. S1 is a force of 4 kN per square meter, and S2 is a force of 8 kN per square meter.
When the diameter or side length of the partially damaged hole of the HDPE double-wall corrugated pipe wall is not greater than 20mm, a polyvinyl chloride plastic bonding solvent can be used to paste a circular plate with a diameter of not less than 100mm
It uses high-strength steel wire and polyethylene plastic as raw materials, wound-shaped high-strength steel wire as the core layer, and high-density polyethylene plastic as the inner and outer layers to form a new type of composite structure wall pipe.
Color inspection. The gas pipe should be yellow or black. When it is black, the pipe must have eye-catching yellow stripes. At the same time, there should be continuous marks with a spacing of no more than 2m on the pipe.
