Undersea pipeline

ASTM A822 is a standard specification for seamless cold-drawn carbon steel pipes, which are mainly used in hydraulic systems and other similar applications, where the forming operation requires small radius bending and flaring.

Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond. The longitudinal ERW seam does not require filler metal.

A tee is also called triplet,three way and “T” pieces and it can be used to either combine or split a fluid flow.

AISI 1045 steel pipe has high strength, high toughness, high wear resistance and high fatigue resistance, and is widely used in mechanical structural components, tool manufacturing and automobile manufacturing.
