Blind Flange Type 05/B1 EN1092-1 PN40

TECHNICAL DESCRIPTION

Blind flanges according to standard EN1092-1 / type 05 / B1 are pipeline elements with a wide size range, which are used as silencers in the construction of steel pipelines and pipe segments (spools).

We stock blind steel flanges according to EN1092-1 type 05 / with sealing surface B1, but we also have the necessary machining equipment, which allows us to offer flanges with sealing surfaces.

• sealing surface type A, B2, C, D, E, F
• non-standard sealing surfaces on request
• profile grooves for metal sealing rings (segments) type RTJ
• threaded type flanges
• flanges made to customer specifications, and others.

SUPPORTED MATERIALS IN STOCK:

• Carbon steel
