Precautions when using ANSI B16.5 A182 F304 Forged RF Stainless Steel Plate Flanges

　　ANSI B16.5 A182 F304 Forged RF Stainless Steel Plate Flange is a type of pipe fitting, which refers to a butt welding flange with a neck circular pipe transition and butt welding of the pipe fitting. It is not easy to deform, sealed, and widely used, with corresponding rigidity and elasticity requirements and reasonable reverse welding refinement transition. The gap between the weld joint and the joint surface is large, and the joint surface is not affected by welding temperature deformation. It adopts a more complex roller shaped structure. Suitable for pipelines with large pressure or temperature fluctuations, as well as high-temperature, high-pressure, and low-temperature pipelines. It is generally used for connecting pipelines and valves with PN greater than 2.5MPa, and is also suitable for flat welding flanges on expensive, flammable, and explosive pipelines.

　　But what should be noted when using ANSI B16.5 A182 F304 Forged RF Stainless Steel Plate Flanges?

　　Stainless Steel Plate Flange refers to a type of flange that inserts pipes into the inner ring of the flange. Stainless Steel Plate Flange, split plate welding flanges, PL and neckless flat welding flanges, etc. The difference between Stainless Steel Plate Flange and non neck flat welding flange is that in the welding part of the pipeline, the Stainless Steel Plate Flange with a neck is more than the welding part without a neck. Stainless Steel Plate Flange welding only requires single-sided welding, and flat welding is a better welding method because the verticality of the pipeline and flange is good, and the pipeline will not tilt.

　　Stainless Steel Plate Flanges have convenient material selection, simple manufacturing, low cost, and are widely used for flange covers. However, they have poor rigidity and cannot be used in chemical pipeline systems that meet supply and demand requirements, flammability, explosiveness, high vacuum, height, and hazardous situations. The sealing surface has a flat and protruding surface.
