Matte Lamination Induction Heating Carbon Steel Alloy Steel Stainless Steel Expander

we have achieved national patent with national independent intellectual property.

By the core technology of the patent-Steel Tube OD Hot Expansion, the requirements of different kinds of diameters of pipesi the large diameter pipes and kinds of non-standard steel pipes with different diameters are satisfied, especially for the production of small batch steel pipe with various specifications.i it has processed T250 special steel, terminal sensitive cartridge case special steel and titanium alloyi .

It is the main production technology to produce large outside diameter steel pipe, high pressure steam piping of power station and nuclear power plant .

The expanded pipes has been widely used in the fields of military industry, aerospace industry and marine industry equipment manufacturing, which has made a great contribution to national defense and energy construction.
