As is known to all, stainless steel pipe has a wide application in our life and industry. Different fields are in need of stainless steel pipes with different properties. For example, stainless steel pipes for water and oil transportation should have good sealing properties. Stainless steel pipes for boiler and heat exchanger industry have good heat resistance. Stainless steel pipes for ship building industry have good high hardness. Here are some of the pipe production processes which can make stainless steel pipes to have these good properties.
Firstly, cleaning is an important process. The surface of austenitic stainless steel pipes must be thoroughly cleaned, to eliminate carbonaceous residues, grease and oil, prior to heat treatment or annealing because the presence of residues results in carburization that, in turn, reduces corrosion resistance properties.
Secondly, annealing makes stainless steel pipes surface bright and smooth. All Ferritic and martensitic stainless steels can be process annealed by heating in the ferrite temperature range, or fully annealed by heating above the critical temperature in the austenite range. After the pipe production process, the stainless steel pipe can have bright surface which can be a mirror.
Thirdly, among pipe production process, hardening is also important. Using tempering, quenching and austenitising methods, stainless steel pipes can be hardened and the temperature range is 980 to 1010°C.
Different pipe production processes make different types of stainless steel pipes. However, the stainless steel pipes have many similarities. For example, stainless does not rust as you think of regular steel rusting with a red oxide on the surface that flakes off. Also, stainless steel is easily welded, but the welding procedure is different than that used with carbon steel. Almost all types of stainless steel pipes have good anti-tensile strength.
As stainless steel tube has such a wide application, many people begin to wholesale stainless steel pipes for construction and other industries. These pipes have good performance in many fields. Therefore, stainless steel pipes are well-received among customers. If you are a wholesaler of stainless steel pipes, Shangshang is a good choice to cooperate with you. It has provided a lot of high-quality pipes for many large projects. In addition, the price is competitive and the service is good.
