摘要

The purpose of this paper is to discuss the mechanical properties of piping materialsrnand the piping database design. The mechanical properties of piping materialsrnproduced by companies are very useful information during the design and safetyrnmanagement of oil and gas pipeline. The primary mechanical properties which meetrnthe international or domestic standards are slightly different. Sometimes therndifference of yield strength can reach up to dozens of mega Pascal. The 376 groupsrnof X70 grade pipeline steel produced by An Gang Steel Company (ANSTEEL) andrn139 groups produced by Pohang Iron and Steel Co. Ltd (POSCO) were adopted inrnorder to acquire the statistics of mechanical properties. The results indicate thernaverage yield strength of ANSTEEL X70 steel is 1.12 times Specified MinimumrnYield Strength (SMYS) and POSCO 1.18 times SMYS respectively. According to therndata characters, the management database of the mechanical properties was designedrnbased on Computer/Server structure. The remote database query system was appliedrnbased on Brower/Server structure.
