ATS offers in-depth assessments to assist in identifying the root cause of a wide variety of pipe failures. These forensic and failure analyses can be performed on HDPE, PVC, copper, ABS, CPVC, HDPE, polyethylene, cast iron and kitec pipes.
PE & HDPE Pipe PE100 is the third generation of pipe grade PE. It has an optimum balance of three key properties: Minimum Required Strength (MRS) – this provides long-term strength and creep resistance. Stress crack resistance (sometimes referred to as slow crack growth resistance). Puhui Pipe manufacturer in China

2/12/2017· This is my strength test of parts made from recycled HDPE. I could not believe how strong this material turned out to be. The fact that the threads were madePuhui Pipe manufacturer in China
14/9/2017· HDPE (high-density polyethylene) is a strong, solid plastic that has many appliions when it comes to building materials. Some facility managers aren’t sure that HDPE provides a stronger construct than other plastics, but HDPE has been proven to be one of the more durable plastics on the market, making it a formidable opponent to other plastics that are available.
Long-term hydrostatic test is a long-term test that simulates the life span of a pipe in a shorter time than its normal lifetime. In this test, polyethylene pipe samples are placed under constant internal pressure at 20 ° C for 100 hours or 80 ° C for 165 hours, depending on the size of the pipe and the type of primary material determined.
The city has decided to replace the failing HDPE with a pipe that has proven reliability; one with a resilient future - Ductile iron pipe. 1 Rutledge, M., “Water-treating chemical causing early failure in Hamilton pipes,” Journal-News , Butler County, OH, Deceer …
