What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel welded pipe is also a hollow section of steel, but it is welded through the plate into the steel pipe, so there is a welded steel pipe welding gap.
The hot rolling, hot extrusion and cold drawing (rolling) stainless steel pipes are used for rolling.According to the stainless steel metallographic structure, it is divided into half ferrite half martensite system, stainless steel tube, martensitic stainless steel tube, austenitic stainless steel tube, austenitic iron ferritic stainless steel tube, etc..
Stainless steel seamless pipe featuresFirst, the product of the wall is thicker, it is more economical and practical, the wall thickness of the thinner, processing costs will be substantially increased it; secondly, the product process to determine its performance limitations, generally low precision seamless steel pipe: uneven thickness, tube inner surface brightness low and high cost of fixed length, and the inner surface pitting and black spots difficult to remove; the detection and plastic third, must be processed offline. Therefore, it has its advantages in high pressure, high strength, mechanical structure and timber.
Stainless steel seamless steel tube is a kind of steel strip with hollow section and without seams.
