Shanghai ShengQiu Materials Co., Ltd

Cold Drawn Seamless Steel Pipe , Hot FinishedSeamless Steel Pipe , and Chrome Moly Tubing ShanghaiShengQiu Materials Co., Ltd  is an industry leading supplier of cold drawn seamless and hot finished seamless in carbon and alloy grades. The tightly controlled cold draw process produces tubing with outstanding dimensional accuracy, excellent micro-structure uniformity, and superior surface finish, making it the ideal choice for extreme stress, high pressure, and high temperature applications. Our chrome-moly products offer a very high strength-to-weight ratio, making it an excellent alternative for weight-sensitive applications.   We have the capacity to supply custom cut-to-length tubing within an O.D. range of 6mm to 1100mm a wall thickness range from 1mm to 100mm. Tubing can be supplied to meet a long list of ASTM, SAE, EN, DIN, JIS, and other international standards.   Offering enhanced machinability, tighter tolerances, and higher strength than hot finished p...

  High-precision seamless steel tube   Process introduction: High-quality carbon steel, fine-rolled, non-oxidizing bright heat treatment (NBK state), non-destructive testing, the inner wall of the steel pipe is brushed with special equipment and subjected to high-pressure washing, the anti-rust oil on the steel pipe is used for anti-rust treatment, and the two ends are sealed for dust-proof treatment.   Main feature: The inner and outer walls of the steel pipe have high precision and high smoothness. After heat treatment, the steel pipe has no oxide layer, and the inner wall has high cleanliness. The steel pipe bears high pressure, cold bending does not deform, flaring and flattening without cracks, and can be subjected to various complex deformation and mechanical processing treatments. Steel pipe color: bright white with high metallic luster.   The main application: Automobile steel pipes, users who have high requirements on the precision and smoothness...
