As a  Seamless Stainless Steel Tubing Supplier , share with you. Due to the characteristics of the two-phase structure, DSS has the advantages of both ferritic stainless steel and austenitic stainless steel through proper control of chemical composition and heat treatment process. Advantages of  Duplex Stainless Steel Pipe  compared to austenitic stainless steel: Duplex Stainless Steel Pipe (1) The yield strength is more than double that of ordinary austenitic stainless steel, and it has sufficient plastic toughness required for forming. The thickness of the tank or pressure vessel made of duplex stainless steel is 30-50% less than the commonly used austenite, which is conducive to reducing costs. (2) It has excellent resistance to stress corrosion cracking. Even the duplex stainless steel with the lowest alloy content has a higher resistance to stress corrosion cracking than austenitic stainless steel, especially in environments containing chloride ions. Stress corrosion

As a  Welded Stainless Steel Pipes Manufacturer  China, share with you. The high requirements of the surface  ASTM A249 Welded Steel Tube  are the distinguishing characteristics of other steels. In fact, in addition to the high requirements for cold-rolled stainless steel welded pipes, the surface also has high requirements for hot-rolled stainless steel welded pipes. Since most of the medium-leveling equipment on the market is domestically produced, many of these are relatively older models. During processing, as long as the damage is caused by scratches on the board surface, it is easy to cause damage to the board surface. Therefore, when processing equipment on the upper plate, factors of various types of protective plates must be considered. Austenitic Stainless Steel Pipe It involves the material conveyed by the feeding platform. The feeding platform needs to use electrical rubber plates instead of steel plates. Conveyor platforms require nylon rolls instead of steel roll

The formation of  Stainless Steel Pipe Ferritic  welds is mostly straight welded pipe forming. Straight seam welded pipe forming can be divided into two categories: continuous forming and discontinuous forming. Here we introduce the continuous forming process. As a  Ferritic Stainless Steel Pipe Supplier , share with you. Compared with the same type of carbon steel, stainless steel strip or stainless steel sheet has the characteristics of high strength, strong sensitivity to work hardening, good abrasion resistance, high possibility of bonding and poor thermal conductivity. Therefore, during the forming process of stainless steel welded pipe, Special attention should be paid to the above characteristics in order to obtain a good molding effect. For stainless steel welded pipes, the more important is welding after forming. Therefore, the requirements for welded pipe forming, in addition to obtaining a good shape, also require providing a good weld for welding. The weld of stainless s

Application of Duplex Stainless Steel Pipe in Desalination Due to the high chloride ion concentration in seawater, equipment and pipelines of seawater desalination systems will face severe corrosion. Traditional  Austenitic Stainless Steel Pipe  often suffers local corrosion damage such as pitting, crevice corrosion, and stress corrosion. Duplex stainless steel happens to be in the above-mentioned corrosion. Excellent performance in the type, becoming one of the main materials. Among them, the evaporator condenser tube in the multi-stage flash seawater desalination method mostly uses 2507 super duplex stainless steel tubes instead of titanium or copper-nickel alloy, and the shell of the flash chamber can be 2205, which has been adopted by the Libyan desalination plant. The high-pressure pipeline of the reverse osmosis method and the high-pressure pump in a high chloride environment use 2507 steel, which is comparable to 6Mo super austenitic stainless steel. Duplex Stainless Stee

There are many ways to make  Stainless Steel Seamless Pipe . Some customers require stainless steel seamless pipes to be rounded. So how should this be done? Let ' s take a look at the manufacturing method of stainless steel seamless tube with  Seamless Stainless Steel Tubing Supplier . Stainless steel seamless pipe is long steel with a hollow cross-section and no seams on the periphery. The thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the higher the processing cost. Therefore, it shows its superiority in terms of high pressure, high strength, and mechanical structural materials. Stainless Steel Seamless Pipe 1. If not required, both sides are recessed inward to avoid cracking of stainless steel seamless pipes; 2. If there is a requirement that the surface of the stainless steel seamless tube cannot be concave, the use of a plug method can be guaranteed; 3. The raw materials of stainless steel seaml
