Galvanized pipes should not be used for gas pipelines, because the surface coating of galvanized pipes may corrode when exposed to gas, thus creating safety hazards. Common gas pipeline materials include stainless steel, copper, tinned copper, etc.
Galvanized pipes are pipes made by hot-dip galvanizing ordinary steel pipes, with a layer of zinc on the surface, which has the characteristics of corrosion resistance and rust resistance. It is widely used in construction, doors and windows, highway guardrails, billboards, ships, furniture, and other fields.
Gas is a flammable and explosive gas, and the safety of its transmission pipeline is very important. According to relevant standards and requirements, the materials of gas pipelines should have the following characteristics: pressure resistance, corrosion resistance, heat insulation, high-temperature resistance, fire resistance, etc.
Although galvanized pipes look strong, it is not feasible to use them in gas pipelines, because after galvanized pipes come into contact with gas, chemical reactions may occur, resulting in corrosion and shedding of the zinc layer, which will cause gas leakage, fire, or explosion.
Common materials that can be used for gas pipelines include stainless steel, copper, and tinned copper. Stainless steel has good corrosion resistance and can meet the use requirements of gas pipelines; copper has strong corrosion resistance and thermal conductivity, and is a very good choice in some gas pipelines that require high pressure; tinned copper also has good resistance to corrosion in gas pipelines and can be used for a long time.
