Hot Expanding Seamless Pipe

Hot Expanding Seamless Pipe Specification range OD: 8"-36" WT: SCH10-SCHXXS Materials: 10#, 20#, 45#, 16Mn, GrB, Q345B MOQ:6t Hot Expanding Seamless Pipe

Introduction:The hot expanding seamless pipe (hot expanding steel tube) is made from the production process of hot-expanding. It is widely applied in conveying fluid, such as petroleum, natural gas, coal gas, water and some solid materials, also ship-building, chemical fertilizer equipment etc.The pipe is with the advantage of:1. These pipes are with low density but strong contractility. 2. The diameter of the pipe 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 as required.

Further information of hot expanding steel tube:1. Executive standards of hot expanding seamless pipe: GB/T 8162/8163, ASME B36.10, ASTM A106/A532. Specification rangeOD: 8"-36"WT: SCH10-SCHXXS3. Materials for hot expanding steel tube: 10#, 20#, 45#, 16Mn, GrB, Q345B, X42-56, ST44, ST52 etc.4. Testing for the hot expanding seamless pipe: eddy current or hydrostatic or ultrasonic or intergranular corrosion etc.5. Packing: Bundles, seaworthy packing, as required.
