MS Flange Adaptor

The flange adaptor is the most basic type of dismantling joint. On one side, it has a flange connection in accordance with the required flange standard, on the other an insertion socket for the pipe. A variety of standard pipe types can be connected.

flange adaptors are available for a variety of pipe types. The anti-torque bolts also make the flange adaptor suitable for a fast “one-man installation”.

There are two types of Flange Adapters
1) Weldable Type Flange Adapter
2) Flange Type Flange Adapter

Flange Type Adaptor

AEF - WFA

The ANANT is equipped with two flanges and one follower end-ring. This design offers optimal gasket control with the separate stud bolts applying pressure to the gasket independently of the tie-rods making the flange connections. This allows a reduction in the number of tie-rods required as their function is restraining only. The AEF - WFA comes equipped with 25 % tie-rods for PN 10 and PN 16 and 50 % tie-rods for PN 25 and PN 40 applications.
The AEF - WFA also makes an unrestrained set-up possible. Here no threaded tie-rods are used allowing the dismantling joint to act as a limited expansion joint absorbing noises and vibrations in the pipeline. This variant requires a fixed point in the pipeline. Anchoring is required if the pipe end can be pulled out of the dismantling joint
Both versions of the AEF - WFA are available in the pressure ratings PN 10, PN 16, PN 25 & PN 40 and in nominal sizes of DN 50 to DN 1600, with a standard longitudinal adjustment of ± 25 mm. Connection flanges to any standard are available upon customer request. Larger nominal sizes, higher pressure ratings and non-standard build lengths are also available on request.

The AEF - WFA with four flanges and 100 % tie-rods is the ultimate solution for challenging installations. The additional flange results in an increased construction length which makes it possible to slide the threaded tie-rod between end flanges during installation and removal. The AEF - WFA is also suitable in situations where the overall space only just corresponds to the construction length. This allows sideways insertion making the AEF - WFA ideal for cases where the connection flanges are fixed e.g. where pipes protrude out of the wall.
The additional flange also makes a time-saving preliminary installation of valves possible. The valve and dismantling joint can be fitted together in the pipeline assembly which are then fitted and clamped together (and removed again) together with the dismantling joint. A further advantage is the continuous threaded tie-rods on one side which makes it possible to remove the valve only.
The AEF - WFA can be locked at the required length with adjustability of± 25 mm when installed in pipelines. Connection flanges can also be delivered according to different standards.

AEF - FFA

Equipped with three flanges, the AEF - FFA is the perfect solution for all standard and non-standard applications. It is easy to install and remove thanks to the standard longitudinal adjustability of ± 25 mm and thus offers perfect support during the installation and removal of valves. The AEF - FFA has connection flanges with the same dimensions at both ends and is lockable. The AEF - FFA dismantling joint with 100 % continuous threaded tie-rods ensures complete restraint and a leakfree operation. The AEF - FFA is available in standard nominal sizes (see dimensions and weights table) and larger sizes and higher pressure ratings up to 100 bar are always possible depending on customer requirements.
