PIPE LENGTH The terms used to designate the length of HDPE pipes are:“SRL” (“single random length”): means that the pipe has any random size between 5-7 meters; generally, pipes below 2 inches in diameter are manufactured with SRL, i.e. shorter (or half measures) of larger bore pipes Puhui Pipe manufacturer in China
2 PE PIPE—DESIGN AND INSTALLATION closely together. Density affects many of the physical properties associated with the performance of the finished pipe. Properties such as stress crack resistance, tensile strength, and stiffness are all affected by the base

Compared to varnished pipe, PE coated pipe have better wear resistance. 3PE have smooth surface, its manning coefficient is 0.009. Because of smooth internal surface and non-sticking performance, 3PE coated HDPE pipe shows higher ability for transporting, and …
PE, polyurethanes and PVC are widely used thermoplastics for agricultural pipes, tubing, hose pipes and for creating custom pipe solutions. Although no plastic tubing product can universally handle all appliions, and there are certain differences that need to be considered per appliion area.

Chapter 9 PE Pipe Joining Procedures 328 The principle of heat fusion is to heat two surfaces to a designated temperature, then fuse them together by appliion of a sufficient force. This force causes the melted materials to flow and mix, thereby resulting in fusion.
3LPE Coated Pipes consist of 3 layers for pipeline coating. Layer 1 consists of Fusion Bonded Epoxy. This later provides protection against corrosion and is fusion bonded with the blasted HDPE surface. Layer 2 is a copolymer adhesive which has excellent chemical

The PE & ROTO lining is carried out only after the pipe spools are fabried & hydrotested. No welding is allowed on the pipe spool once the PE or ROTO lining is done. The pipe trunnion meer & line stop meers, if applicable, shall be welded prior to the lining.
What are the defects in pipe manufacturing HDPE heating tube defects uneven heating, oxidation, decarbonization, heating cracks, overheating, over-burning. A good pluing system requires quality pipelines. Even a minor defect in the manufacturing of pipes can

History Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. When his colleagues Eugen Baerger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long –CH 2 – chains and termed it polymethylene.
Coating In general, the coating process includes: heating the pipe, the coating appliion and curing/cooling of the coated pipes. For each process, we can build equipment suitable for a wide range of pipe diameters and lengths.
Pipe coil trailer loaded with 100metres of 180mm PE pipe. Image Courtesy:Exova Utilities Coiled pipe generally has significant degrees of curvature and ovality, and as these prevent electrofusion (or mechanical joints) of good quality being produced, as well as increasing drag and the risk of scoring damage during insertion, the pipe should be passed through a straightener re-rounder before Puhui Pipe manufacturer in China
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
