The inner wall of the PE pipe is smooth, has low friction resistance, energy saving, and does not change with time. The pressure loss is about 30% smaller than that of steel pipes. Therefore, smaller PE pipes are a better method than steel pipes. PE pipe has good hygienic performance, does not contain additives, and will not pollute drinking water. The standard of polyethylene material is 0 (the minimum standard), which is moldy material. Compared with other commonly used plastic materials, polyethylene is much more resistant to mold, so it can be used for a long time without scaling.

why use hdpe pipe?

HDPE pipes are widely used because they have excellent material properties and are easy to install and operate. The most important thing is that they are low in cost.

　　 High Density Polyethylene, the English name dao is "High Density Polyethylene", or "HDPE" for short. HDPE is a non-polar thermoplastic resin with high crystallinity. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging purposes. HDPE has good electrical properties, especially the high dielectric strength of insulation, making it very suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance, even at room temperature and even at low temperatures of -40F.

how to join hdpe pipe?

1. Small-caliber baiPE pipe (below DE110) or thin-walled PE pipe uses the socket du method, which is the same as the hot-melt zhiPPR pipe, but the heating temperature is 1653 different. Low density PE pipe (LDPE) 160 degrees, medium density 190 degrees, high density (HDPE) and ultra-high molecular weight 210-235 degrees.

2. A special hot melt machine is required for large diameters, which are basically divided into DE110, 160, 200, 250, 315, 400, 450, 500, 630 models, using butt joints (that is, pipes and pipes are directly connected after melting)

3. It can also be connected by electric fuse, but the cost of capacitor connection is relatively high, and it is generally used for PE gas pipe connection. In actual work, we must pay attention to the flatness and cleanness of the pipe connection opening, so as to ensure the quality of the PE pipe connection and ensure the safety of the project.

can hdpe pipe be used for hot water?

HDPE is very flexible and can withstand harsh on-site handling better than more fragile polymers such as PVC. ... HDPE can be used as hot water, as the lining of multilayer pipes, where the strength is provided by another pipe layer (such as aluminum), but the multilayer pipe alone cannot provide all the performance advantages of plastic.
