Small diameter seamless steel pipe
can be called small diameter seamless steel pipe, small diameter seamless steel pipe can also be divided into: seamless small diameter steel pipe and straight seam (also can be called welding) small diameter seamless steel pipe, generally in the outer diameter of steel pipe 89mm below, 4mm above;
Can be collectively referred to as small diameter seamless steel pipe.Small-diameter cold-drawn seamless steel pipe is a kind of circular, square and rectangular steel with hollow section and no seams around.Seamless steel pipe is made of steel ingot or solid billet through perforation into capillary tube, and then through hot rolling, cold rolling or cold drawing.Seamless steel pipe is hollow section, a large number of used for conveying fluid pipe, steel pipe and round steel, compared to solid steel in the bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used.
