Nipoflange and Weldoflange are flanged outlets used to branch pipelines at 90 degrees. They are manufactured as a combination, in one single solid piece of forged steel, of a standard flange and a branch connection (like Weldolets, Elbolets, Latrolets, etc). Flanged outlets are manufactured from NPS 1/2″ to 12″ and rating from 150# to 2500#, RF or RTJ. The available schedules are 10S, STD, XS, 160 and XXS and can be installed on run pipes from NPS 3/4″ up to 36″.
A Nipoflange is used for branch pipelines at 90 degrees and is a product manufactured by combining a welding neck flange with a forged Nipolet.
However, a Nipoflange is a solid single piece of forged steel and not two different products welded together.
To install a Nipoflange, the piping staff has to weld the Nipolet part of the device on the run pipe and bolt the flanged part on the flange of the branched pipe.
Nipoflanges are available in different materials, such as carbon steel ASTM A105 (high-temperature service), ASTM A350 (low-temperature carbon steel), ASTM A182 (stainless steel grades, including duplex and super duplex) and nickel alloys (Inconel, Incoloy, Hastelloy, etc). Nipoflanges are also manufactured in the reinforced variant, which has additional mechanical strength compared to a standard Nipoflange.

A Weldoflange is conceptually similar to a Nipoflange, as that they are a combination between a weld neck flange and a branch connection (a Weldolet in this case). Weldoflanges are made out of a single piece of solid forged steel, not by welding separate parts together.

ELBOFLANGE AND LATROFLANGE
Other less common types of flange Olets is the so-called Elboflange (a combination of a flange and an Elbolet) and “Latroflange” (combination of a flange with a Latrolet). Elboflanges are used to branch a pipeline at 45 degrees.

Other special types of flanges are the expander and reducer types.
