EN1092-1 TYPE11 FLANGE(WN)

Views: 5     Author: Chaos     Publish Time: 2024-01-19      Origin: Site

EN1092-1 is the production standard for European standard flanges, mainly used for pipeline and equipment connections, including connecting pipes, valves, pumps, and other equipment. Its characteristic lies in the use of flange connections with strict matching ratios, which can effectively improve the quality of the pipeline and ensure safety and reliability during use. In addition, the standard also defines requirements for the size, shape, surface treatment, pressure rating, and flange type of flanges, and specifies the structure, materials, and static calculation methods of flanges to meet the needs of different application scenarios.

The flange types in EN1092-1 standard include: TYPE01 plate flange; TYPE02 loose flange; TPYE05 blind flange; TYPE11 butt welding flanges, etc. The following are all flange types included in this standard.

What Type Of Flange Is EN1092-1 TYPE11

As can be seen from the above picture, the TYPE11 type flange is a weld neck flange. Weld-neck flange is a type of flange pipe with a neck and a circular steel pipe connection, which is connected to the pipe end by butt welding. Weld neck flanges are not easy to deform and are used in conjunction with bolts and gaskets. They have good sealing performance, corresponding rigidity and elasticity requirements, and reasonable welding thinning transition. The distance between the welding junction and the joint surface is large, avoiding the joint surface from being deformed by welding temperature. They adopt a relatively complex horn shaped structure and are suitable for pipelines with large pressure or temperature fluctuations, as well as pipelines with high temperature, high pressure, and low temperature.

EN1092-1 TYPE11 flange dimension:DN15-DN4000;

Pressure range:PN 2.5, PN 6, PN 8, PN 10, PN 16, PN 25, PN 40, PN 63, PN 100;

Sealing surface:Type Flat Face (FF), Type B Raised Face (RF), Type C Tongue, Type D Groove, Type E Spigot, Type F Recess, Type G O-ring Spigot, Type H O-ring Groove。

PN25 EN1092-1 TYPE11 Flange Dimension

The EN1092-1 weld-neck flange standard is widely used in many industries, such as petroleum, chemical, pharmaceutical, etc. Its application industries include but are not limited to pipeline systems, pressure vessels, valve components, pump connections, etc. By using the EN1092-1 weld-neck flange standard, efficient and reliable equipment connections can be achieved, improving production efficiency and product quality, while also complying with relevant national and regional standard requirements.
