Precision pipe is a high-precision, high-brightness seamless steel pipe produced by cold drawing or cold rolling. Its inner and outer diameters can be accurate to within 0.2mm, while ensuring bending and torsional strength, it is light in weight, so it is widely used in the manufacture of precision mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, bearings, etc.

Product Features

Main features: There is no oxide layer on the inner and outer walls
of the steel pipe, no leakage under high pressure, high precision,
high finish, no deformation after cold bending, no cracks in
flaring and flattening.

Application

Mechanical structures, Hydraulic Equipment, Auto parts, Steel sleeves.

Delivery StatusCode
Cold working / hardBKNo heat treatment is carried out after the final cold working, so
that only a small deformation of the tube is possible
Cold working / softBKWAfter the final heat treatment, a small amount of cold working is
performed, and limited cold deformation (eg bending, flaring) is
allowed for the end processing of the steel pipe.
After Cold working
Stress relief annealing
BKSAnnealing below Ac 1 after final cold working to relieve cold
working stress
AnnealingGBKFull annealing of the steel tube in a protective atmosphere after
the final cold working
NormalizingNBKNormalizing of the steel pipe in a protective atmosphere after the
final cold working

Production Process

Different processing methods and corresponding auxiliary procedures
are selected according to the processing performance of the metal,
the size of the pipe, the quality requirements, and the investment
and benefits. The basic processes of cold-rolled and cold-drawn
pipes are:

(1) pipe material supply, the pipe materials used are hot-rolled
finished pipes or semi-finished pipes, extruded pipes and welded
pipes;

(2) pipe material preparation, including inspection, bundling, acid
Washing, cleaning, rinsing, neutralizing, drying, lubricating,
etc.;

(3) Cold working (cold rolling or cold drawing);

(4) Finishing of finished products includes heat treatment of
finished products, straightening, sampling, cutting heads and
tails, inspection ( Manual inspection and various flaw detection),
hydraulic test, oiling, packaging, storage, etc. Different products
have different finishing contents.
