Synopsis : Oil sands development by steam injection method requires a material with high strength at design temperature and good field weldability for steam distribution system. Quenched and tempered low C-Mo-V steel pipe and fittings (KSC-X65M) have been developed for this purpose, and their properties studied. Strengths of the pipe and fittings satisfied the specifications at room temperature and 350. Tensile strength of the girth welded joint is almost as high as that of the parent metal, at both room temperature and 350. The steel has good weldability and can be field-welded with cellulosic type electrode. The value of 67% of the 10 5hr. creep rupture strength at 350 is sufficiently higher than 1/3 of the tensile strength; so the allowable stress is determined simply by the tensile strength. |
