The Difference Between BS4504 PN10 Blind Flange And BS4504 PN16 Slip On Flange?

BS4504 PN10 Blind Flange isa Circular Flanges designed to be utilized in conjunction with Fittings, Pipes, and Valves. The BS 4504 Flanges must be PN Designated in accordance with the Steel Flanges Standard. This standard includes nominal pressures ranging from PN 2.5 to PN 40, in addition to nominal diameters. The BS4504 PN16 Slip On Flanges Standard largely corresponds with the Steel Flanges specification. BS4504 has a quantitative size designation that is shared by all parts in a plumbing system.
BS4504 Pn16 flange dimensions apply to flanges that are completely cast or forged, plain, or welding neck style. Although it is obsolete, it is nevertheless used for the specifications of light duty and economical stainless steel flanges.

Advantages Of EN 1092-1 BS 4504 Flange

Puddle flanges are used to keep water from penetrating along the exterior pipe edges of pipes.These run through various concrete buildings like floor slabs, manhole chambers, vaults, cellars, shafts, and so on. EN 1092-1 BS 4504 Flanges is fitted during the building phase.They are an extremely effective technique of closing the area surrounding the outside of pipelines that pass through various types. There are several advantages to employing puddle flanges.It offers Installation ease. It has greater strengthas compared to other flanges. It is inexpensive. It is able to withstand huge weights.It is possible to place it in ceilings, flooring, and walls.
