For the pipe fittings of small size, such as tee, tee and elbow of socket welding and thread, the shape is relatively complex, so the die forging process should be used.
The pipe fittings of special shape or those not suitable for die forging can be manufactured by free forging process.The rough shape of pipe fitting should be forged by free forging; If the tee, should be forged out of the branch pipe.
A tee has three openings, namely an inlet and two outlets; A chemical pipe fitting with two inlets and one outlet, either T-shaped or Y-shaped
Coupling is a kind of fittings commonly used in industrial pipe connection.
The a105 is a mild steel forgings similar to the 20 steel.
Since only one type of carbon steel forging is specified in this standard, a105 is considered a type of forging carbon steel grade.
ASTM A105, also known as carbon steel, is an iron-carbon alloy with an internal carbon content of nearly 2 percent.
A105 is considered a type of forging carbon steel grade.
