ASME/ANSI B16.5 stainless steel RF nipo-flange

 

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 connectionsOn 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).

APPLICATIONS

 

This alloy was developed for conditions involving severely cyclical heating conditions where components

must be capable of retaining there strength and ductility after long exposure. The alloy is used extensively

in seal rings in gas turbine engines where it's low coefficient of thermal expansion is also important.
