摘要:
为了满足酸性载荷条件下管材能够承受高压、大流量酸性油气输送需要，采用抗酸性能优异的低Mn高Nb耐酸性热轧板卷，经过优化和控制成型及焊接工艺，开发出低Mn高Nb耐酸性X65 MS耐酸性Ф323.9 mm×9.5 mm HFW电阻焊管。力学性能检测表明，试制焊管的性能达到了X70钢级的标准要求，尤其是具有优异的焊缝低温韧性和压扁性能，－40 ℃下焊缝冲击功大于136 J，管环压扁到平板相贴时焊缝区域未见任何裂纹，且管体硬度低，最高硬度仅229 HV10。HIC腐蚀试验表明，管母和焊接接头表面均无氢鼓泡，剖面裂纹率均为零。SSCC腐蚀试验表明，管母和焊接接头在100%SMYS高应力条件下，试样表面无任何裂纹。沟槽腐蚀试验表明焊接接头沟槽腐蚀敏感性系数平均值仅1.06。可见开发的X65 MS耐酸性HFW焊管具有十分优异的抗HIC/SSCC性能和抗沟槽腐蚀性能，可以在含硫化氢的油气输送中安全服役。
Abstract:
Under acidic loading condition, in order to make steel pipe meet the requirements of transporting large flow acid oil and gas under high pressure, adopting low Mn high Nb acid resistance hot-rolled coil, after optimization , forming control and welding technology, the low Mn high Nb X65MS acid resistance Ф323.9 mm×9.5 mm HFW electric resistance welded pipe was developed. The mechanical properties test results indicated that the performance of trial-produced welded pipe reach X70 steel grade standard requirements , especially with the excellent performance of low temperature toughness and flattening, the impact energy of weld seam is greater than 136J under -40℃. The flattening test showed no cracks appear in weld area when the pipe ring was compressed to attached, and the highest hardness of HFW pipe only 229HV10. The HIC corrosion tests showed that no hydrogen bubbles appear in the surface of pipe body and welded joints, the crack rate of samples profile is zero. The SSCC corrosion tests showed that without any crack appears in samples surface of pipe body and welded joint,under the conditions of 100% SMYS high stress. The groove corrosion tests showed the average of grooving corrosion sensitivity coefficient of welded joint is 1.06. It proved that the developed X65MS acid resistance corrosion HFW welded is with very excellent anti HIC / SSCC performance and grooving corrosion resistant performance, and can be applied in safe transportation of oil and gas with hydrogen sulfide.
