  pipe fittings cap have five conventional methods of flaw detection are ray detection method, ultrasonic flaw detection method, magnetic particle testing method, eddy current flaw detection method and penetration testing method. Pipe will not attack corrosion, pitting, corrosion or wear. Generally do not have any resistance to corrosion.

  Seamless Butt Welded Pipe Cap wall thickness grade is indicated by the pipe number, the common pipe cap number is Sch40 and Sch80. When selecting the welded pipe fittings, the pipe should be the same as the pipe number of the pipe to which it is connected, that is, the strength of pipe and pipe, Thick), except that the wall thickness of the end of the pipe is the same as the wall thickness of the pipe. China's National Standard for Steel Butt Welded Pipe Fittings cap (GB12459) and China Petroleum & Chemical Corporation Standard (SH3408) are basically the same as ASME B16.9, B16.28, JIS, JPI-7S and JPI-7S-1.
