Classification of Seamless Steel Tubes - Carbon Steel Pipe

GB/T3639-1983 (cold drawn or cold rolled precision seamless steel pipe). Mainly used for mechanical structure, carbon pressure equipment, requires high dimensional accuracy, good surface finish steel. Its representative material is 20, 45 steel. GB/T3094-1986 (cold drawn seamless steel pipe shaped steel pipe). Difference between hot-rolled and cold-rolled seamless Dec 19, 2020 · From the appearance to distinguish cold-rolled seamless steel pipe surface bright, caliber size is smaller than hot-rolled seamless steel pipe. The hot-rolled seamless steel pipe has a larger caliber than the cold- rolled seamless steel pipe, and the surface has obvious scale or red rust. 3.Accuracy.
