American standard EN1092-1 P245GH flangeAlso known as: welding flange and neck flange, etc. The English representative letter WN; Material types include: carbon steel, alloy steel and stainless steel; Sealing surface type: convex surface (RF), full plane (FF), concave and convex surface (MFM), tongue and groove surface (TG), ring connection surface (RJ), etc. Common standards: ASME B16.5 and ANSI standard series; It is worth noting that the neck of the American standard EN1092-1 P245GH flange is higher than the national standard with neck welding flange.

　　American standard EN1092-1 P245GH flangeIt is suitable for pipelines with large pressure or temperature fluctuations or high temperature, high pressure, and low temperature pipelines. It is generally used for the connection of pipelines and valves with PN greater than 2.5 MPa; at the same time, it is also used in pipelines that transport expensive flammable and explosive media; Generally applicable to basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, hot water, fire protection, electric power, aerospace, shipbuilding, etc.

Performance characteristics of American standard EN1092-1 P245GH flange:

1. The neck of the American standard high neck flange will be higher than the national standard neck welding flange;

2. Not easy to deform, good sealing performance, wide application.

3. Pipelines for transporting expensive flammable and explosive media, pipelines with large pressure or temperature fluctuations, or high temperature, high pressure, and low temperature pipelines.American standard EN1092-1 P245GH flange.

4. The choice of sealing surface is diversified, and different sealing surface forms can be selected according to different pipelines to achieve the best sealing effect.

　　5.American standard EN1092-1 P245GH flangeThe welds are available for X-ray inspection.
