we strictly carry out the quality system iso9001:2000 standard
during production process,
adopts advanced modern production management and quality
management, to obtain high quality steel pipe . After acid
pickling, cold rolling, cold drawn, and then adopt advanced
technology for high temperature heat treatment (NBK status) to
produce steel pipes with surface: bright, smooth, high precision,
high polish, both inside and outside wall without oxidation layer,
internal and external wall of high precision, mechanical
performance fits well in any Angle bending, and can bear high
pressure, cold bending deformation, flaring, flattening, tensile
and other require ments, our steel tube doesnot burst when cold
bending, no cracks, no oxide layer and the internal and external
wall, etc.
The precision steel tube is made by seamless steel tube ,which is
through non-oxygen tempering treatment to eliminate the surface and
internal stress. The product is of high precision and ductility,
easy to be processed into various required shapes, and cross
section of the tube will not be reduced or flattened. The surfaceis
of high presicion, and the surface hardness is moderate and easy to
be connected. The inner hole and surface are treated with
phosphating anti-rust treatment without acid cleaning and rust
removal.
The company covers an area of more than 8000 square meters with an
annual output of more than 5,000 tons. The main products are: cold
drawing or cold rolling precision seamless steel pipe and related
supporting bright tubing, conveying fluid seamless steel pipe. Our
company produce seamless steel pipe in Europe (Germany) DIN series
standard is the basic standard, using high quality tube blank, on
the basis of this combined with our unique steel pipe manufacturing
process,. Steel pipe is produced in high precision and high cold
drawn. Because of the special bright heat treatment process, the
inner and outer walls of steel tube are not oxidized after heat
treatment.
