ASTMA53 VS ASTMA106

[antonio09]

I NEED TO KNOW THE FOLLOWING. I DON'T FIND IN MY COUNTRY 10" DIAM. SCHD. 40 STEEL PIPE ASTM A53 SEAMLESS. I FOUND 10" SCHD. 40 CARBON STEEL PIPE ASTM A106. I VERIFIED THE ASTM A53 AND LET ME KNOW THE FOLLOWING: THIS PIPE CAN MADE WELD, FORGE, BEND, ETC. THE ASTM A106 IS CARBON STEEL SEAMLESS PIPE FOR HIGH TEMPERATURE. THIS PIPE CAN MADE FORGE, BEND. YOU CAN SEE THAT NOT PERMIT WELD.
I NEED TO BUTT WELD THIS PIPE. THE APPLICATION IS FOR AIR CONDITIONING. PLEASE ANYBODY CAN SAID IF THIS PIPE IS BETTER THAT OTHER.

There's no problem welding A-106 pipe. The welds you're referring to comparing the specs refer to method of construction. A-53 includes pipe fabricated with longitudinal welds, A-106 is strictly seamless drawn carbon steel. A-106 Grade B is actually the standard pipe in my field, which is oil & gas processing facilities, in all standard temperature applications.

There is also an A53B seamless grade of pipe, identified in ASME B31.1. This can be kind of confusing, as there's the lesser-grade, much more well known (and readily available) A53B (ERW), also identified in the same code.
