Product Description

GOST 9567-75 Precision steel tubes

This standard is applied to steel pipes of particular accuracy after cold drawing or hot rolling.
Cold drawing pipes are produced of the following length:
Not fixed length - from 1 to 11.5 m
Fixed length - from 4.5 to 9 m.
Length multiplied fixed length  - up to 9 m with allowance 5 mm for each cutting. Per customer request it can be stated another allowance.
Max length deviation for fixed and multiple length are to be + 10  mm.
