HDPE Gas Pipe 630mm Diameter Supplies Affordable HDPE Gas Pipe
The gas pipe must withstand a certain pressure, and usually a PE resin with large molecular weight and better mechanical properties, such as HDPE resin, should be used. HDPE resin has low tensile strength, resistance to pressure difference, poor rigidity, poor dimensional stability during molding and difficult connection, and is not suitable as a material for water supply pressure pipes. However, due to its high hygienic index, LDPE, especially LLDPE resin, has become a common material for gas pipes. LDPE and LLDPE resins have low melt viscosity, good fluidity and easy processing, so the selection range of their melt index is also wide, usually MI is between 0.3-3g/10min.

Good hygienic performance: No heavy metal salt stabilizer is added during the processing of PE pipe, the material is non-toxic, no scaling layer, and no bacteria breed, which well solves the secondary pollution of urban drinking water.
Good corrosion resistance: Except for a few strong oxidants, it can resist the erosion of various chemical media; no electrochemical corrosion.
Long service life: PE pipes can be safely used for more than 50 years under rated temperature and pressure conditions.
Good impact resistance: PE pipe has good toughness and high impact resistance, and heavy objects directly press through the pipeline without causing the pipeline to rupture.
Reliable connection performance: The strength of the PE pipe hot-melt or electro-melt interface is higher than that of the pipe body, and the joint will not be disconnected due to soil movement or live load.
Good construction performance: the pipeline is light in weight, the welding process is simple, the construction is convenient, and the overall project cost is low.
Connection of pipes:
Electrothermal fusion: A special electric fusion welding machine is used to connect straight pipes to straight pipes and straight pipes to pipe fittings. Generally used for pipes below 160mm.
Hot-melt butt connection: use special butt welding machine to connect pipes, generally used for pipes above 160mm.
Steel-plastic connection: It can be connected by flange, screw thread and other methods.
In order to facilitate construction and ensure construction quality, corresponding tools should also be prepared.

High Mountain Pipe Management Industry With 19 years of experience in R&D, production and sales of plastic pipe fittings, HDPE pipes are of good quality. In order to meet the actual needs of modern high-quality buildings and the design concept of environmental protection and silence, the company has introduced advanced production equipment and manufacturing technology, and has successively developed grooved ( HDPE) HDPE mute, HDPE grooved mute pipe, HDPE grooved drainage pipe compression drainage system and HDPE siphon drainage system series products. HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section. PE has excellent resistance to most household and industrial chemicals. hdpe pipe factory adheres to the factory policy of "credibility, quality and management as the fundamental goal", with moderate price, dedicated service, and customer satisfaction as the purpose, abiding by contracts and keeping promises and famous all over the country.
Q: Can I customize the size I need?
Q: Which payment method can your company use?
A: T/T, L/C or full trade insurance. You can choose the one that is convenient for you.
Q: How and when can I receive my goods after payment?
A: For small batch products, they will be delivered to you by international express (DHL, FedEx, TNT, etc.) or by air. It usually takes 3-5 days to receive the goods after delivery. For high-volume products, it is worthwhile to see the goods and deliver them. It takes several days to several weeks to reach the destination port, depending on the location of the port.
