ASTM WPB A234 B16.9 CARBON STEEL WELDING AND SEAMLESS PIPE FITTINGS

.Seamless pipe fitting plays an important role in connection Pipe system, control, diversion, shunt, seal, support the action such as spare parts.

The main products include carbon steel elbow, carbon steel flanges, carbon steel tee, carbon steel cross, carbon steel reducer, carbon steel cap, etc. Main standards include GB, ASTM standard, JIS standard, and for American standsrd, including Chemical standards, Sinopec tube standard, the standard of power connectors.

The difference between seamless fitting and welding fitting:

Seamless pipe manufacturing process is under the temperature of the stamping out a hole in the steel billet, under the high temperature, and tool steel after the stamping and drawing become soft and spiral forming from the hole. So the pipe wall thickness is not uniform and high degree of eccentricity. Thus allows seamless tube wall thickness difference is than the tube wall thickness difference is big. Have a seam pipe is made by precise manufacture (width is 4 to 5 feet per roll). Usually these manufacture's biggest wall thickness difference is 0.002 inches. The width of the steel plate is cut into PI d, where d for pipe diameter. The wall thickness of the slit of tolerance is very small, and the circumferential wall thickness is uniform.

So after manufacturing fitting, the wall thickness will have same wallthickness.
