　　Stainless seamless steel pipe is a kind of long steel with hollow section and no joints around. Stainless seamless steel pipe

　　Features of stainless seamless steel pipe:

　　First, the thicker the wall thickness of the product is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be; Secondly, the process of the product determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surfaces of the pipe, high sizing cost, and pockmarks and black spots on the inner and outer surfaces are not easy to remove; Third, its detection and shaping must be handled offline. Therefore, it shows its advantages in high pressure, high strength and mechanical structure materials.

　　Type of stainless seamless steel pipe:

　　The connection and rolling methods include hot rolling, hot extrusion and cold drawing of stainless seamless steel pipes.

　　According to different metallographic structures of stainless steel, it can be divided into semi Ferritic and semi martensitic stainless seamless steel pipe, martensitic stainless steel pipe, austenitic ferritic stainless steel pipe, etc.

What are the process flows for API 5L welding steel pipes?

Mar .13.2025

API 5L welding steel pipes often uses the Shielded Metal Arc Welding (SMAW) technique, commonly called stick welding. This method uses a stick-shaped electrode to generate an electric arc that melts the metal during welding. The welder uses a flux-coated electrode to protect the weld metal and prevent atmospheric contamination.

A53 Hot-dip galvanized seamless steel pipe production process

Mar .11.2025

ASTM A53 Hot-dip seamless pipe is to make molten metal react with iron matrix to produce alloy layer, so that the matrix and coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot-dip galvanizing tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.

What are the ways to reuse waste A312 stainless steel seamless pipe?

Mar .06.2025

ASTM A312 Stainless steel pipes are pipes used to transport different types of fluids and are widely used in construction, machinery, chemical industry and other fields. Stainless steel materials have the advantages of high strength, high corrosion resistance, easy processing and not easy to deform, so they have become the preferred material in many industries. Stainless steel pipes can be divided into seamless stainless steel pipes and welded stainless steel pipes according to the production process.
