For upstream pipelines, stainless steel, galvanized pipes, and copper pipes with plastic coatings are recommended. Galvanized pipes can only be connected by threading; welding is not allowed. For downstream use, stainless steel and plastic gas supply pipes are recommended. Both HG and SH have relevant design and construction regulations.
Stainless steel pipes have advantages such as a long service life, resistance to the formation of impurities over time, and resistance to corrosion; for these reasons, they are also widely used in pipelines for instrument air supply. In addition, new types of pipes such as aluminum-plastic composite pipes and PVC polyester pipes are continually emerging and being used in gas supply systems; these pipes offer advantages such as corrosion resistance and ease of installation and maintenance
