Description
 With the rapid development of economy in our country, the
national stepped up infrastructure construction, the implementation
of the national project such as "west to east gas pipeline",
"south-north water diversion project", and the CN-KZ oil pipeline
project,for all kinds of liquid and gas pipeline engineering
application is more and more widely used,the flange will have broad
market prospects and development space by leaps and bounds.Flange
is widely used in chemical, petrochemical, food, water, gas
pipelines and other urban public plumbing, water supply and
drainage and other professional, submarine pipeline and national
wind power flange industry emerging industry.Therefore, flat
welding flange has become an indispensable accessory products.Flat
welding flange is first made the flange blank, then flange blank
finish machining, so the processing cost depends on the accuracy of
the flange blank.Currently the flange blank mainly made by cast
steel molding, casting molding, forging forming, cold roll forming
and cutting molding.Â
Advantage of our hot rolled technology
Â
1.High production efficiency;
Â
2.Save raw material,solve the problem of the line segment end to
end;
Â
3.High rate of finished products,high precision,good flatness and
high yield;
Â
4.The specification of rolling can be adjusted according to the
customers requirements;Â
Â
5.Save the energy resoures.
