Shandong Donghong Pipe Industry achieved a breakthrough in ultra-large diameter pipeline manufacturing on May 13, creating the world's first mass production technology for DN1200 steel wire wear-resistant pipes. This innovation fills the gap in domestic high-wear-resistant large-diameter pipe technology, breaks through the limits of traditional processes, promotes my country's pipeline industry to move towards high-end equipment manufacturing, and demonstrates the company's hard-core strength in independent innovation.

Because of the particularity of the conveying medium of gas pipe, the safety of the gas pipe is very important. The installation and use of gas pipes should strictly abide by the relevant regulations to avoid illegal installation.

Gas pipelines can be mainly divided into gas steel pipes and HDPE gas pipes, which have their own advantages and can be applied to different gas pipeline projects.

The connection method of HDPE double-wall corrugated pipe is also a lot, but the most practical and most commonly used is nothing more than the socket connection and the heat shrink sleeve connection. Here we will introduce them respectively:

As a common pipe in urban gas transmission and distribution system, HDPE gas pipe has been widely used in the gas industry because of its good anti-corrosion performance and flexibility. However, compared with steel pipes, their strength is low and they cannot withstand higher pressure levels, so the selection of gas pipes should be judged according to the actual project needs and conditions. How to judge, let us understand in detail as fllows.
