China Wholesale 30 Inch Seamless Steel Pipe Suppliers - High Quality Stainless Steel Pipe – Xinsuju

Product Desscription

Brinell, Rockwell and Vickers hardness indexes are commonly used to measure the hardness of stainless steel pipes. Stainless steel pipes can be divided into CR series (400 Series), Cr Ni series (300 Series), Cr Mn Ni series (200 Series) and precipitation hardening series (600 Series). 200 series – chromium nickel manganese austenitic stainless steel 300 series – chromium nickel austenitic stainless steel.

Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, bimetallic composite pipes, coated and coated pipes to save precious metals and meet special requirements.

Stainless steel pipes have a wide variety, different uses, different technical requirements and different production methods. At present, the outer diameter range of steel pipes is 0.1-4500mm and the wall thickness range is 0.01-250mm.

Stainless steel pipe can be divided into seamless pipe and welded pipe according to the production mode. Seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe, cold drawn pipe and extruded pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe. There are various connection modes of stainless steel pipes. The common types of pipe fittings are compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type and derivative series connection mode combining welding with traditional connection. According to the purpose, it can be divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, petroleum cracking pipe) and marine pipe.
