1.  Large Diameter Steel Pipe Making Machine - Steel Pipe Expanding Machine

By the core technology of the patent-Steel Tube OD Hot Expansion, the requirements of different kinds of diameters of pipes，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.

Short Production Time, Greater Flexibility

Traditional pipe manufacturing requires a lot of time to change out a pipe's size. As a result,  large order quantities are required from the customers.

DEZHOU YAXING's Thermal Pipe Expansion process can change out pipe sizes in 3 hours. Shorter production time allows for greater flexibility in response to emergency order situations. It also lowers minimum order quantities to a manageable level, giving distributors the ability to carry some of those odd sizes they previously couldn't.

The equipment is invented by our factory chief engineer Mr. Fu Bingzhong , which has 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 pipes
，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.（it has processed T250 special steel, terminal sensitive cartridge case special steel and titanium alloy）.
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.

2. Mainly technical parameters
：
1) material：such as P91-92/T91-92
、Q235、Q345、45#、A106B-C、12CrMoV
2) diameter：φ48～φ1420mm
3) wall thickness
：3～120mm（sectional design and manufacturing the equipment）
3) length：3～24m

YAXING EXPANSION MACHINE can produce Seamless Pipe in sizes from 60mm through 1500mm OD. Wall thicknesses can be as much as 120mm thick.
