Hot-dip galvanized seamless pipe, that is, after the seamless steel pipe is formed, in order to improve his anti-corrosion performance, a layer of zinc is plated on the surface. The hot-dip galvanized seamless pipe uses a hot-dip galvanizing process. Seamless pipe is a round, square and rectangular steel with a hollow section and no seams on the periphery. Production process of seamless pipe: hot rolling, hot expanding, cold drawing. Therefore, seamless steel tubes are divided into hot rolled and cold rolled (dial) seamless steel tubes.

Hot rolled seamless pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipes.

It is light in weight and is an economical cross-section steel. It is widely used in the manufacture of structural parts and mechanical parts. It is used for various conventional weapons, such as steel pipes for barrels and barrels.

The hot-dip galvanizing process of hot-dip galvanized seamless pipe is a galvanizing process often used now. It is an effective metal anti-corrosion method, mainly used in metal structures and facilities in various industries. The hot-dip galvanizing production process mainly includes: original plate preparation → pre-plating treatment → hot dip plating → post-plating treatment → finished product inspection, etc.
