摘要:
针对阿曼Khazzan气田项目集输管线建设用LC65-2205双相不锈钢焊管的生产,依据项目采购标准对LC65-2205双相不锈钢焊管进行了拉伸性能、冲击韧性、显微硬度及抗点蚀性能等的研究分析,并通过定量金相技术测定了母材、焊缝和热影响区(HAZ)三个位置区域的铁素体含量。结果显示,开发的LC65-2205双相不锈钢焊管管体母材、焊缝及热影响区110 ℃高温拉伸性能、-56 ℃低温冲击韧性、显微硬度值分布、抗点腐蚀性能、铁素体含量及尺寸精度均满足且优于技术标准要求,可用于含H2S、CO2、Cl-等强腐蚀性介质的油气输送。
Abstract:
For the production of LC65-2205 duplex stainless steel welded steel pipe for the construction of the Khazzan gas field project in Oman, the tensile properties, impact toughness, microhardness and pitting resistance of LC65-2205 duplex stainless steel welded pipe were studied according to the project procurement standard. At the same time, the ferrite content of the three locations of the base metal, weld and heat affected zone(HAZ) was determined by quantitative metallographic techniques. The results show that the exploitative LC65-2205 duplex stainless steel welded pipe has good mechanical properties and corrosion resistance. The 110 ℃ high temperature tensile properties of tube base metal, weld and HAZ, -56 ℃ low temperature impact toughness, microhardness value distribution, pitting corrosion resistance, ferrite content and dimensional accuracy meet and exceed the technical standards. The pipe could be used for oil and gas transportation with strong corrosive media such as hydrogen sulfide, carbon dioxide and chloride ions.
