The first and most widespread kind is the EN 1092-1 TYPE 01A flat welding flange. As it was previously explained, the labelling of the flange provides a lot of information: EN 1092-1 indicates the reference standard, TYPE 01 reveals that it is a welding flange and A stands for flat sealing surface. This kind of flanges are used for connecting pipes and they are welded by means of overlap weld. Then, they are joint by means of bolts.

Also the second kind of flanges is a flat welding kind (TYPE 01), but their sealing surfaces are different from the previous one, as they have raised faces (B). EN 1092-1 TYPE 01B raised face flanges host a low relief collar surrounding the central hole of the flange, which proves to be useful for checking the position of the gasket. They are welded by means of overlap weld and they are joint by means of bolts.

The third kind of flanges available in our catalogue is the EN 1092-1 TYPE 02A lap joint flange. Their labelling can be easily broken down into EN 1092-1 (reference standard) TYPE 02 (lap joint flange) A (flat sealing surface). They are loose flanges to be joint by means of welding collars; bolts are used for their connection.

The fourth kind of EN 1092-1 flanges in our stock are flat (A) blind flanges (TYPE 05). EN 1092-1 TYPE 05A blind flanges are used combined with flat welding flanges, raised face flanges or collar as end caps for tubes.

The fifth kind concerns welding neck flanges (TYPE 11) with raised faces (B). The kind of welding used is butt welding.

The sixth kind of EN 1092-1 flanges you can find in our stock identifies threaded flanges (TYPE13) with raised faces (B). They have a female thread for coupling with threaded male ends.

The last kind, EN 1092-1 TYPE 33, establishes the dimensions of welding collars to be used in combination with EN 1092-1 TYPE02A loose flanges or DIN 2642 flanges from pressed stainless steel.

Moreover, Fitting Service can supply, on customer’s request, further EN1092-1 types. See on the table below our full range of EN 1092-1 flanges.
