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).

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

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

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

Forging of Alloy S alloy should be carried out at 2100/1600ºF (1145/870ºC) up to the final 20% of cross-section

reduction, this final 20% being carried out from about 1900ºF (1040ºC) to 1500ºF (815ºC).




The alloy is solution treated at 1950ºF (1065ºC) and subsequently aged at temperatures from 800 through to

1600ºF (425 through 870ºC), where a whole range of tensile and impact properties may be obtained.
