外基管负责承压和管道刚性支撑的作用,内衬管承担耐腐蚀的作用。 The outer base pipe is responsible for pressure bearing and rigid support of the pipeline, while the inner liner is responsible for corrosion resistance. 外基管可以根据输送介质的流量和压力要求,选用不同通径和壁厚的碳钢管材。热镀锌钢管、直缝焊管、螺旋管、低中压流体输送用无缝钢管、高压锅炉、石油裂化用无缝管钢管、管线管等。直径可从φ20-φ1020mm,壁厚可从2.5-50mm。 Carbon steel pipes of different sizes and thicknesses can be selected according to the flow and pressure requirements of the conveying medium. Hot-dip galvanized steel pipes, straight welded pipes, spiral pipes, seamless pipes for low and medium pressure fluid transportation, high pressure boilers, seamless pipes for petroleum cracking, pipeline pipes, etc. Diameter can be from 20 to 1020 mm, wall thickness can be from 2.5 to 50 mm. 内衬管可以根据输送介质化学成分,选用不同的耐腐蚀合金。可以是奥氏体不锈钢 304、304L、316、316L、铜基合金、镍基合金、哈氏合金、钛、钛合金、双相不锈钢等新型高耐腐蚀合金材料。内衬管壁厚可以根据使用寿命和焊接工艺的要求从0.3-4mm。 Different corrosion resistant alloys can be selected according to the chemical composition of the conveying medium. It can be made of 304, 304L, 316, 316L austenitic stainless steel, copper-based alloy, nickel-based alloy, Harrington alloy, titanium, titanium alloy, duplex stainless steel and other new high corrosion resistant alloy materials. The wall thickness of liner can be 0.3-4 mm according to service life and welding process requirements. |
