Oil and gas

Boiler tubes is a one of seamless pipe. Manufacturing methods is the same as seamless tube, but it has the stringent requirements for manufacture of steel pipes.

ASTM A672 B70 carbon steel EFW (electric arc furnace smelting) pipe is a stainless steel pipe that complies with the American ASTM standard. It is mainly used for the transportation of media such as steam, water, oil and other media in high temperature and high pressure environments. This kind of pipe has a high carbon content, good strength and corrosion resistance, and is suitable for long-term use in various harsh environments.

Specifications:ASTM A 106, ASME SA 106 Size Range:1/2” NB to 36” NB Thickness:SCH 40, SCH 80, SCH 160, SCH XS, SCH XXS, All Schedules Type:Seamless / ERW / Welded / Fabricated / CDW

A335 Grade P23 Pipe is a low alloy carbon steel (Cr-Mo) that is self quench in air, where the welding adquire high hardnees and residual stress not recomended to put it directly in services that demand critical conditions.
