The common due diligence mentality for property owners, facility managers and the government is to ignore the conditions of these aged pipes until they break. But once a pipe breaks, a water/sewer system fails or corrosion turns our drinking water red, the fix is not a walk in the park and it is not easy on the wallet. Ironically, there is ample technology in the U.S. to predict and prevent all types of pipe problems.
Poly pipes or polyethylene pipes are of different types but you will select the type based on the usage. Polyethylene is a type of plastic which when heated melts and can be molded into the desired shape. Hence it is also called thermoplastic. Polyethylene changes to liquid when heated and becomes solid after cooling. A poly pipe or polyethylene pipe is a thermoplastic that is blended with few necessary ingredients to strengthen the service capacity.
The HDPE pipe liners are custom built to match the exact required specification. It is manufactured on the basis of the size of the pipe. Traditionally, an HDPE pipe linear is manufactured slightly larger than the actual pipe in diameter. Analyzing the fact that improper fusion of pipeline liner can degrade the quality, few well known HDPE pipe liner suppliers initiate the fusion process in a closed area.
Each cause normally requires a special approach to address it so once the inspection reveals what caused the damage or blockage to the pipe, then appropriate tools will be used to get rid of that problem.
They used a polyester felt tube liner, saturated with resin and coated with a waterproof layer which was inserted into the pipe. Hot water or steam was circulated through the tube, which hardened the resin. Because of the styrene-laced by-product of using felt with water or steam curing, the CDOT environmental division directed the liner company to construct a temporary holding pond with an EPDM (ethylene propylene diene monomer) geomembrane liner to capture any styrene-laced cure water. The liner company then had to pump out and haul the water off-site to avoid any environmental contamination. If they had used UV fiberglass cured in place pipe, they would not have had this problem causing additional time and expense to the job.
