ASTM 1330 seamless steel pipes and tubes

Brief introduction of cold drawn seamless steel pipe

Cold-drawn precision seamless steel pipe is a precision cold-drawn seamless pipe with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and help improve product quality.

Classification of galvanized welded pipe

Cold-drawn precision seamless steel pipe is a precision cold-drawn seamless pipe with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and help improve product quality.

If you want to obtain a small-diameter seamless steel pipe with a smaller size and better quality, you must use cold rolling, cold drawing or a combination of the two. Cold rolling is usually carried out on a two-roll mill, and the steel pipe is rolled in an annular pass formed by a circular hole groove with variable cross-section and a stationary tapered plug. Cold drawing is usually carried out on a 0.5-100T single-chain or double-chain cold drawing machine.
