  Stainless steel plate specification

  Stainless steel plate refers to a plate made of stainless steel, which can be divided into hot-rolled stainless steel plate, cold-rolled stainless steel plate and hot-pressed stainless steel plate. Stainless steel plate has the advantages of strong corrosion resistance, good thermal processing performance, high tensile strength, high compressive strength, etc., and is widely used in the fields of shipbuilding, chemical industry, electric power, petroleum, automobile, construction, furniture and so on.

  Properties and uses of 316 and 316L stainless steel

  316 and 317 stainless steel are molybdenum-containing stainless steel species, and the molybdenum content in 317 stainless steel is slightly higher than that of 316 stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good chloride attack properties, so it is often used in marine environments. 316L stainless steel has a maximum carbon content of 0.03 and can be used in applications where annealing after welding is not possible and where maximum corrosion resistance is required.

  How is stainless steel welded pipe produced

  In the 19th century, rolling technology was the only technology used to produce stainless steel and industrial tubes. The process steps involved in this rolling technique are long. It is with the help of funnel rolls that the rolled sheets are made into circular cross-sections and these rolled strips are then welded in a welding process Fortunately, with development and new technologies, various processes for manufacturing stainless steel tubes and pipes have been formed Stainless steel tubes and tubes are now manufactured by continuous tube mills using tungsten inert gas. No filler metal or forge welding process is used in this technique.

  Comparison between ERW steel pipe and LSAW steel pipe

  The difference between ERW straight seam electric resistance welded steel pipe and straight seam submerged arc welded (UOE) steel pipe: Straight seam welded steel pipes are divided into high-frequency resistance welding and submerged arc welding according to the welding process. Straight seam submerged arc welding is referred to as UOE, and straight seam high-frequency resistance welding is referred to as ERW.

  Introduction of Production Technology of Large Diameter Longitudinal Welded Pipe

  Longitudinal welded pipes are made of steel plates or strips that are bent and then welded. According to the weld form, it is divided into straight seam welded pipe and spiral welded pipe. According to the purpose, it is divided into general welded pipe, galvanized welded pipe, oxygen blown welded pipe, wire casing, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welded thin-walled pipe, electric welded special-shaped pipe and spiral welded pipe.
