Types of galvanized steel pipes and their applicable scenarios

Classification of uses

According to the use, galvanized steel pipes can be subdivided into structural galvanized pipes, hydraulic support galvanized pipes, petrochemical equipment galvanized pipes, etc. Structural galvanized pipes are often used in building structures, bridges, road guardrails and other fields because of their good corrosion resistance and mechanical properties; Hydraulic support galvanized pipes are widely used in oil and gas exploitation and transmission pipelines because of their high corrosion resistance and pressure resistance; Galvanized pipes for petrochemical equipment are especially suitable for the transportation pipelines of chemical equipment, which need to meet the multiple requirements of corrosion resistance, pressure resistance and wear resistance.

Specification and size classification

Galvanized steel pipes can be divided into small, medium and large sizes according to the size of the specification. Small-size galvanized pipes such as DN15 to DN40 are suitable for household water supply and drainage, gas pipelines, etc.; Medium sizes such as DN50 to DN100 are commonly used in piping systems for industrial and municipal works; Large-size galvanized pipes such as DN125 and above are more used in large-scale infrastructure such as bridges, highway drainage systems, etc.

Material classification

In terms of material, galvanized steel pipes mainly include carbon steel galvanized pipes and stainless steel galvanized pipes. Carbon steel galvanized pipe has low cost and wide application, which is suitable for general industry and construction fields; Stainless steel galvanized pipes are used in occasions with higher requirements for pipe materials because of their better corrosion resistance.
