BS 4504 Silp On PN6

Standard Basis: BS 4504 is a British standard for circular flanges used in pipes, valves, and fittings. Among them, BS 4504: Section 3.1: 1989 specifically specifies the requirements for steel flanges. This standard is substantially consistent with ISO 7005-1: 1992 (E) Part 1 Steel Flanges.
Size Specifications: The nominal size (DN) range is generally DN10 to DN600, and the nominal pressure (PN) covers different classes such as PN6, PN10, PN16, PN25, and PN40.
Materials: Common materials include:
Carbon steel: e.g., ASTM A105, S235JR, etc.
Stainless steel: e.g., ASTM A182 F304, F304L, F316, F316L, etc.
Sealing Face Types: Main types include Raised Face (RF) and Flat Face (FF).
Manufacturing Process: Usually produced by forging or plate processing. The forging process enables the flange to have better mechanical properties.
Application Fields: Widely used in basic engineering fields such as chemical industry, construction, water supply and drainage, petroleum, light industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, and shipbuilding.
Price Range: The price varies depending on factors such as material, size, and pressure class. For example, a carbon steel slip-on flange with PN16 and DN100 may cost between a few US dollars and several dozen US dollars, while stainless steel flanges are more expensive.
Packaging and Transportation: Generally packaged in wooden cases. Transportation methods can be sea freight, air freight, or express delivery. Specific delivery terms include CIF, CFR, FOB, EXW, etc.
