x52 line pipe

Stainless steel is not easy to rust because forming x52 line pipe a rich chromium oxide in the surface of steel body can protect the steel body, 201 materials belong to high manganese steel is 304 high hardness, high carbon low nickel.
Stainless steel tube heat treatment abroad widely used continuous heat treatment furnace with protective gas without oxidation, for the intermediate heat treatment, heat treatment and finished products in the process of production because of lack of oxidation of the surface of the light can get, and cancel the traditional pickling process.
Penetration depth of molten stainless steel welded pipe x56 line pipe requirements, do not contain oxide inclusions, heat affected zone as small as possible, argon arc welding of tungsten inert gas protection has good adaptability, high welding quality and good penetration performance, its products in the chemical industry, nuclear industry and food industry widely used.
High frequency welding is used for carbon steel welded pipe production has a history of more than 40 years, but is used for welding stainless steel pipe is a new technology. Its production of economy, make its products more widely used in building decoration, home appliances and mechanical structure.
High frequency welding has the power to different material, outer diameter, wall thickness of steel pipe can reach higher welding speed. Compared with argon arc welding is the welding speed of more than 10 times. Therefore, in the production of general use stainless steel pipe with high productivity.
Welding speed is not high is the deficiency of argon arc x60 line pipe welding, to improve the welding speed, the foreign research and development a variety of methods. Which has developed from a single electrode welding torch adopts multiple electrode welding torch welding method applied in the production.
Stainless steel pipe welding various welding methods all have their own advantages and disadvantages. How to foster strengths and circumvent weaknesses, several welding methods will be combined to form a new welding technology, meet the demand for stainless steel welded pipe quality and production efficiency, is the new trend of the current stainless steel welded pipe technology development.
