This specification covers five grades of electric-fusion arc -welded straight-seam or spiral-seam steel pipe in 4″ to 92″ inclusive with wall thickness up to 1 ” inclusive. Tests to be performed shall include one longitudinal tension test for the steel, one reduced-section production weld test for the pipe, and hydrostatic test for each length of the pipe.
The outside circumference of the pipe shall not vary more than 1. Yield strength,min Ksi Mpa. The steel shall be made by one or more of the following processes: Electric-fusion, Arc- welded, straight seam or spiral seam, steel pipe 10 – mm diameter inclusive with nominal wall thickness up to 25 mm inclusive.
Heat analysis of each heat of steel was made to determine the percentage of the elements as per chemical requirements. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification and the grades of steel of the manufactured pipes.
