Detailed Description
1 Production technology: Hot-expanding Advantage: This kind of steel pipe is 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) WT: SCH10-SCHXXS 4 Materials: 10#, 20#,45#,16Mn, GRB, Q345B, X42-56, ST44, ST52 etc. 5 Testing: Eddy current, Hydrostatic, Ultrasonic, Intergranular corrosion etc. 6 Packing: in bundles with steel strips, seaworthy packing as per customer's requirements 7 Application: Hot-expanding seamless steel pipes are widely used in fluid transmission such as petroleum, natural gas, coal gas, waster as well as shipbuilding, large constructions, machinery, chemical fertilizer equipment, electricity industry etc.
