GOST pipes precision alloys
GOST 9567-75
Precision seamless pipe can be made cold-deformed or hot-rolled according to dimensions specified by State Standards 8732 and 8734 from carbon and alloy steel grades: 10, 20, 35, 45, 40Х, 30ХГСА, etc. (as previously agreed). For cold-deformed pipe, upsetting drawing or, in combination with it, rolling is used.
Thin-walled tubes of small diameter are rolled on roller mills before non-drawing.
Pipes
Precision pipes are used in instrumentation, in automobile industry (steering wheels, seats, bumper parts, cardan shafts, shock absorbers, hydraulic cylinders, etc.).
