Hot Expanding Seamless Steel Pipe

Hot Expanding Seamless Steel Pipe

Hot Expanding Seamless Steel Pipe

1. Production technology: Hot-expanding

Advantage: these pipes are with low density but strong contractility. The dia is expanded by helical rolling or drawing. This precision rolling can thicken the pipe in a short time. Which can produce non-standard or special models of seamless pipes.

2. Executive standards: GB/T 8162/8163, ASME B36.10, ASTM A106/A53

3. Specification range:

OD: 8-36

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: Bundles, seaworthy packing, or as required by customers.

7. Application

Hot-expanding seamless pipe are widely used for conveying fluid, such as petroleum, natural gas, coal gas, water and some solid materials, also ship-building, chemical fertilizer equipment etc.
