EN 1092-1 Type 05 Blind Flange
Type 05 / Type 05A Blind Plate Flange | PN 6–40
EN 1092-1 Type 05 blind flanges, also referred to as Type 05/A blind plate flanges, are flat, solid flanges designed to close the end of pipelines, valves, or pressure vessel nozzles.
Manufactured in accordance with EN 1092-1, these blind flanges are suitable for pressure ratings from PN 6 to PN 40 and are widely used in industrial, water, chemical, and energy piping systems.
Type 05 blind flanges provide a reliable and economical solution for pipeline isolation and future system expansion.
We are a professional manufacturer of steel forged flange in China,Blind flange,Blind raise face flange EN 1092-1 TYPE 05/A blind Flange,DIN 2527 Blind Flanges,JIS B2220 Blind Flanges
The blind flanges or blank are Flanges used for terminating of piping in many different industries
EN 1092-1 Type 05A Blind Flanges refer to a specific subtype of blind flanges (used to close the end of a pipe system) as defined in the European standard EN 1092-1, which governs steel flanges for pipes, valves, and fittings..
The blind flanges PN16 by DIN EN1092-1 type 05 are flange fitting that is used to close the end of pipes, valves, or equipment nozzles. A blind flange is a round plate that has boltholes but no center hole, and because of this feature, this flange is used to close off the ends of piping systems and pressure vessel openings.
EN 1092-1 FLANGE STANDARD
European standard EN 1092-1– concerning flanges for pipes – establishes the requirements for steel flanges based on their nominal pressure (PN) and dimension (DN).
The DIN EN 1092-1 standard covers nominal sizes DN 10 (NPS 3/8″) to DN 4000 (NPS 160″) with pressure designations PN 2.5 to PN 400. These flanges are generally stocked in sizes DN 25 (NPS 1″) to DN 300 (NPS 12″) with a pressure designation of PN 16 in pipe bore and tube bore slip-on, along with blind flanges.
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.
