Introduction to an HDPE pipeline and PPR pipeline. HDPE is a high-density polyethylene. The diameter of HDPE pipes ranges from DN16 to DN315 and is divided into 18 levels. The pressure level is between 0.25Mpa and 1.0Mpa, with a total of 4 grades.
This Material Handling Guide covers a wide range of safety issues regarding the handling, loading, transportation and installation of polyethylene pipe and fittings. site safety, storage guidelines, unloading guidelines, heat fusion joining and installationjust a
The first PE pipe material used in engineering appliions was Type 50 High Density PE HDPE with a long term stress of 50MPa. Subsequently, Medium Density MDPE materials, with improved pipe properties when compared to the earlier high density materials, were used in pipes due to their improved flexibility, ductility, slow crack growth resistance and crack propagation resistance.
This paper presents a brief overview of a challenging project at the Callaway Nuclear Power Plant where HDPE was utilized to replace degraded HDPE buried piping in a Safety Related water system. Callaway was the first Nuclear Power plant to obtain NRC approval and successfully place the HDPE piping system into service in an ASME Section III, Class 3 appliion.

In order to use HDPE fittings for gas in a correct way, it is quite necessary to pay attention to the following installation tips. 1. The room having gas pipelines can not be used as a bedroom, so as to avoid gas leakage, ching fire or endangering the safety of life.
HDPE pipe High-density polyethylene jacket tube is widely used in oil pipelines, gas pipelines, urban heating pipes, water pipes, electricity and other corrosion engineering, product quality and service by the users of a good level.
NBS is the new global leader in providing high-density polyethylene HDPE lining systems for internal pipeline protection. With office facilities in Australia, Brazil, China, and Morocco, NBS can respond quickly with the specialized personnel, equipment and material resources necessary to complete turnkey projects anywhere in the world.
All diameters of solid wall PE pipe are continuously extruded through an annular die. Whereas, for large diameter profile wall pipes, the profile is spirally wound onto a mandrel and heat-fusion sealed along the seams. Solid wall PE pipe is currently produced in sizes ranging from 1/2 inch to 63 inches in diameter.
