Weldoflange, Nipoflange
The Weldoflange and Nipoflange is a combination of a Weld Neck Flange and a supposedly Weldolet or Nipolet.
On the run pipe side a nipoflange is designed like a Forged 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).
Two different pipe branch connections
Forged material
A nipoflange similar to ASME B 16.9 or MSS-SP 97 is manufactured from forged material. That means a nipoflange is a forged fitting without welding seam.
WAZ (acceptance test certificate)
Of course, you may obtain a standard cert. 3.1 with each delivery. Upon request, we are able to deliver a cert 3.2 (normally TüV or other inspection institutions). In the cert. 3.1, the chemical consistenc and the physical characteristics of the material are listed.
Standard and special materials of Steel Flange
Anthermo is able to deliver nipoflanges in standard materials. Upon request special materials are also deliverable.
The Weldoflange and Nipoflange is a combination of a Welding Neck flange and a supposedly Weldolet or Nipolet. The 2 components are manufactured in one piece, and not welded. These Pipe Fitting are primarily in Branch connections. Furthermore, they have an expanded range of special Fitting & Flange and branch connections.

A pipe flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system.
It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Pipe flanged joints are made by bolting together two flanges with a Gasket between them to provide a seal.
Materials for Flanges
Pipe flanges are manufactured in all the different materials like stainless steel, cast iron, aluminium, brass, bronze, plastic etc. but the most used material is forged carbon steel and have machined surfaces.
In addition, flanges, like fittings and pipes, for specific purposes sometimes internally equipped with layers of materials of a completely different quality as the flanges themselves, which are "lined flanges".
The material of a flange, is basically set during the choice of the pipe, in most cases, a flange is of the same material as the pipe.
All flanges, discussed on this website fall under the ASME en ASTM standards, unless otherwise indicated. Asme B16.5 describes dimensions, dimensional tolerances etc. and ASTM the different material qualities.
Dimensions of Flanges
Each flange according to ASME B16.5 has a number of standard dimensions. If a draftsman in Japan or a work preparer in Canada or a pipefitter in Australia is speaking about a Welding Neck flange NPS 6, Class 150, Schedule 40 ASME B16.5, then it goes over the flange which in the image here below is shown.
If the flange is ordered, the supplier want to know the material quality. For example ASTM A105 is a forged carbon steel flange, while A182 is a forged Stainless Steel Flange.
