Flaring Test For Stainless Steel Pipe Jun 27,2022Why do stainless steel pipe crack when they are flared? 1. The chemical composition of raw material, causes itself to be hard and not so soft, such as high carbon content. It is recommended to use low carbon materials such as 304L, 316L, 409L, etc. 2. The weld seam of the pipe is not penetrated and the strength is insufficient. Hensun strictly control the quality during production to ensure that the weld seam is 100% full penetration and without leakage. 3. The hardening that occurs during processing can lead to a reduction in the plasticity of the stainless steel and the creation of residual stresses, which can lead to cracking. In this case, re-annealing can be performed. The stainless steel tube for stainless fuel line, stainless steel exhaust pipe, stainless steel press fitting, stainless steel mechanical tube, stainless steel sanitary tube, beer keg spear, stainless steel furniture tube, etc., often need to be flared, and a flare test can be performed to check whether there are cracks and other defects in the flared mouth to determine whether it is qualified or not.

Hardness Test For Stainless Steel PipeJun 13,2022There are two main factors that affect the hardness of stainless steel pipes: annealing treatment & carbon content. 1. The quality of the annealing treatment of the steel strip and the tube itself is directly related to the hardness of the stainless steel tube. Whether it is 304 stainless steel pipe or tp316l, 201 and other, international standards have corresponding regulations for their hardness. 2. The main function of carbon in ss pipe is to improve the hardness of the pipe, but carbon is also an impurity in stainless steel, the higher the content, the harder it is, and the greater the chance of the pipe rusting. 3. In addition, there is another reason for the 201 stainless steel welded pipe, that is the copper content. Astm a554 201 stainless pipe will be added with copper, its function not only improves the brightness of the pipe, but also increases the toughness of the ss steel pipe, so that the ss tube is softer, which is convenient for processing or bending. Therefore, it does not mean that the harder the stainless tube, the better. If it is too hard, it is not conducive to the bending of the stainless steel pipe. Hensun as a leading stainless steel tube suppliers, will strictly monitor the hardness of the pipe during production, taking the hardness test, to ensure the performance meets the processing requirements of the end user, such as bending stainless steel tubing, stainless steel coil tubing, stainless steel pipe fittings, steel pipe railing, etc.Read More
Four Surface Treatments For Stainless Steel Industrial PipeMay 30,20221. Pickle & Passivate: Hensun got the official license to do pickling & passivation to improves pipe's corrosion resistance. We use environmentally friendly liquids that are safe for human body. Pipes will be thoroughly clean with high pressure pure water. 2. Bright Anneal (BA): Stainless steel tubes are heat treated under protective gas to obtain a bright surface, it helps to eliminate stress & improve weld seam performance, avoid pipe's cracking during bending, flaring, necking and other processing. 3. Outside Polish: offers much shining surface and smooth touching for industrial pipes. 4. Inside polish: gives smooth inside surface for sanitary tubes, helps to reduce residual corrosion.Read More
