Q195 Q215 Seamless Pipe Fittings DN10-DN1200 Heat Treatment

ASTM A234 WPB SEAMLESS ELBOWS CARBON STEEL SEAMLESS PIPE FITTINGS

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.
