ASME/ANSI B16.5 RF Nipo-flange

A Nipoflange is used in the pipe industry like a weldolet or a nipolet for a 90° branch connection.
A Nipoflange is a combination of weldolet, nipolet and flange.
Two different pipe branch connections
On the run pipe side a nipoflange is designed like a weldolet. That means the branch connection
on the run pipe side is a welding connection.
On the other side there it has a flange connection. The flange connection can be designed according
to customers requirements (acc. To DIN or ANSI).
