Steel Tube End Welding Cap Note that the process of manufacturing process: the right approach is: cutting (scribing) - small board fight into the board - forming - nondestructive testing if the test is not done before molding is wrong, can not guarantee after molding products the quality of. In other words, nondestructive testing refers to the final non-destructive testing..

ANSI B16.9 caps specifications

High-quality products

 Since most of the pipe fittings is for welding, in order to improve the quality of welding,  the fittings end are bevelling groove, leaving a certain angle, with a certain edge, which is a relatively strict requirements, how thick edge, and how much deviation angle range has prescribed. Pipe fittings  surface quality and mechanical properties  and  tubes are same. In order to facilitate welding, the connected steel pipe and the fittings  materials  are  the same.
