Nipo flange

Nipo Flange

A pipe connector which is typically used for 90 degree branch pipeline connections is known as a Nipo Flange. This is a forged steel connector which is manufactured by welding a nipolet to a branch flange. The Nipo Flange Standard specification is ASME B16, and they are available in different sizes and material grades. Nipo Flanges Uses are mostly in oil and gas industries. Clients can also get non-reinforced and Reinforced Nipoflange.
