成都无缝钢管厂今年2月对该厂研制的直接(余热)淬火装置进行工业性试验,生产了一批N—80、P—110,X—95高强度石油管以及冻结井用管。经探伤、力学性能、金相、低温性能等全面检测,这批钢管完全符合API标准和有关技术协议的要求。该厂即将用这套装置生产几百吨专用管,随即移入轧管生产线,投入在线运行。 Chengdu Seamless Steel Tube Plant in February this year, the plant developed direct (residual heat) quenching plant for industrial tests, the production of a number of N-80, P-110, X-95 high-strength oil pipe and frozen well pipe. After testing, mechanical properties, metallography, low temperature performance and other comprehensive testing, these pipes fully meet the API standards and the requirements of the relevant technical agreements. The plant is about to use this device to produce hundreds of tons of special pipe, then moved into the rolling pipe production line, put into operation online.
