Pipe fittings are the important parts of oil and gas transmission pipeline, including tee, elbow, cap, reducer, gas distributor etc. Hot extrusion fittings are the key pressure pipeline parts of long-distance pipeline to change the direction of pipeline. They are used in pipeline branch having the effects of changing the direction, distributing the flow and controlling. Hot extrusion fittings are extrusion forming to achieve the size, physical and chemical property of pipe fittings the standards require through many processes such as laying off, welding, hot extruding, heat treatment, test and inspection etc.

Technical Index

X80 hot extrusion pipe fittings are suitable for the X80 steel pipeline engineering with design pressure less than 20 MPa, design temperature from - 40 ℃ ~ 100 ℃, the fluid medium such as the natural gas of purification, crude oil and refined oil etc. The products have stable performance and more than 30 years' service life.

Extension performance

The toughness of charpy impact energy

Advantaged Technology

CPPM can carry out finite element analysis and control forming size of pipe fittings accurately

through thermal simulation technology.

CPPM masters the most cutting-edge method of tee strength calculation and calculates blasting validation of pipe fittings through the finite element analysis.

CPPM masters welding and heat treatment technology with large diameter Pipefitting of grade X80 steel and less than grade X80 steel through about 100 welding technology tests.

CPPM is the only domestic pipe fittings manufacturer which puts forging manipulator into many operations such as mechanized billets charging, process transfer of hot workpieces and mechanized masking of workpiece card etc. to play an important role in improving the pressing quality of pipe fittings, reducing the labor intensity, improving production efficiency and working conditions of pipe fittings'extrusion.

CPPM has 4000t pressure machine whose manufacturing capacity is the largest in domestic manufacturing industry of pipe fitting.

CPPM masters automatic welding technology of high grade pipeline steel pipe fittings.

Product Certification

CPPM has A and B class pressure pipe components manufacture license, and 2 patents of invention, 1 utility model patent certification. Grade X 80 steel pipe fitting with diameter of 48” took the lead in getting the certification of CNPC to fill the domestic blank in December 2008.

Practical Application

X80 hot extrusion pipe fittings took 80% market share in the supply of Central Asia natural gas pipeline and west-east gas transmission pipeline.
