Hot-expanding Seamless Steel Pipe
HOT-EXPANDING SEAMLESS SEEL PIPES
1 Production technology: Hot-expanding
Advantage: this kind of steel pipes are with low density but very
strong contractility. The diameter is expanded by helical rolling
or drawing. The precision rolling technology can thicken the pipe
in a short time. Non-standard or special sizes of seamless steel
pipes can be made through hot expanding technology.
2 Standards: GB/T8162/8163/3087/5310, ASME B36 10, ASTM A106/A53,
API 5L/5CT, DIN
3 Specification range:
OD: 8''-36'' ( 219mm-914mm)
4 Materials: 10#, 20#,45#,16Mn, GRB, Q345B, X42-56, ST44, ST52 etc.
5 Testing: Eddy current, Hydrostatic, Ultrasonic, Intergranular
6 Packing: in bundles with steel strips, seaworthy packing as per
7 Application: Hot-rolled seamless steel pipes are widely used in
fluid transmission such as petroleum, natrural gas, coal gas,
waster as well as shipbuilding, large constructions, machinery,
chemical fertilizer equipment, electricity industry etc.
