Dacon Inspection Services first started testing Intelligent Pigging for HDPE pipes in 2001 and conducted the first commercial inspections in 2004. More then 150 hundred commercial inspection runs in large diameter HDPE pipelines has been completed by end of
HDPE used to be the plan B pipe material for a project. But, HDPE pipe is now in its fourth generation of development and there has been a paradigm shift in its use worldwide. HDPE is no longer a secondary option for projects big and small, but a necessity. If you Puhui Pipe manufacturer in China
Features of HDPE pipes and fittings: Green environmental protection: HDPE pipe non toxic, tasteless, after strict health monitoring, belongs to green building materials, never scale, can effectively improve water quality. Corrosion resistance: HDPE pipelines are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipeline.
Ed = Dynamic instantaneous effective modulus of pipe material, (150,000 psi for HDPE, 400,000 psi for PVC) DR=dimension ratio Technical Service Bulletin 4 Since the fluid being conveyed is usually water, the only variables are the modulus of the pipe and the Puhui Pipe manufacturer in China
Gentex High Density Polyethylene (HDPE) water pipes have been used in appliions since 1995. We manufacture pipes in the desired diameters between 20mm to 1000mm and PN6 to PN20 pressure classes, depending on size and appliion. We use high quality material grade PE 80 and PE 100.

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.
HDPE pipe technical guidance The HDPE Pipe Model, developed by the PE100+ Association with inputs from many industry experts, includes the most frequently asked questions and answers (Q&A''s) of all the elements through the pipe system value chain: design, materials, construction, operation & maintenance, and environmental issues.
From a different material than HDPE pipe fitting gasket transition: When pressurized HDPE pipe remains under two different internal forces. 1. Gives cause environmental stress. 2. Twist and thrust tube are reflected as axial tensile stress at the end of the pipe.

Kuzeyboru HDPE pipes have a minimum lifetime of 50 years and are valid at a temperature of 20 oC. Hdpe pipe life may also vary with chemical bonding with HDPE material. . Our web site includes all Hdpe Pipe Products List in our
Even in heavy loaded areas, where only the strongest — Galvanized iron, Ductile iron, Cement Pipe survive, Plastic in the form of HDPE has scored beyond doubt as an ideal substitute. HDPE is today, the internationally preferred piping material across an unbelievable range of appliions (where strength & long life are key requirements).
