First, the concepts of galvanized steel pipe and stainless steel pipe are different.
● Galvanized steel pipe is a steel pipe with a layer of zinc applied to the outside. This prevents corrosion and extends its service life. Generally, this type of galvanized steel is called galvanized steel.
● Stainless steel pipe is a steel material that resists weak corrosion from air, moisture, and steam, as well as chemical corrosion from acids, alkalis, and salts.

Second, the processing techniques used for galvanized steel pipe and stainless steel pipe are different.
● Galvanized steel pipe has a layer of zinc on its surface, which provides excellent corrosion protection and extends its service life.
● Stainless steel pipe is steel with other metal elements added to it, creating structural changes that prevent rust.

Third, galvanized steel pipe and stainless steel pipe have different applications.
● In addition to being used as line pipe for general low-pressure fluids such as water, gas, and oil, galvanized steel pipe is also used in the petroleum industry, especially for oil well pipes and oil pipelines in offshore oil fields; for oil heaters, condenser coolers, and coal distillation and washing oil exchangers in chemical coking equipment; and for pier piles and support frames in mine tunnels.
● Stainless steel pipe is widely used in industrial pipelines and mechanical components in the petroleum, chemical, medical, food, light industry, and mechanical instrumentation industries. Furthermore, its lighter weight, while maintaining the same bending and torsional strength, makes it widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in the production of various conventional weapons, gun barrels, and artillery shells.
