Stainless Steel Seamless Tube
Stainless steel seamless pipe is a long steel material with a hollow section and no seams around it. The thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the processing cost will increase significantly.The process of this product determines its limited performance. Generally, seamless steel pipes have low precision: uneven wall thickness, low brightness of the inner and outer surfaces of the pipe, high cost of sizing, and pitting and black spots on the inner and outer surfaces that are difficult to remove; its detection and Shaping must be processed offline. Therefore, it reflectsits superiority in terms of high pressure, high strength, and mechanical structural materials.
Product testing: dimensional testing, appearance testing, PMI material testing, hydraulic testing, eddy current testing, non-destructive testing, mechanical property testing, intergranular corrosion testing, etc.
