BS Compliant Flanges & Fittings — Frequently Asked Questions

BS (British Standards) compliant flanges refer to industrial pipe flanges that conform to various British national standards, such as BS 4504 (for PN-rated flanges) or BS 10 (for Table-rated flanges). Dipti Metal Industries manufactures and supplies these components, predominantly used in the United Kingdom, other European countries, and many Commonwealth nations, or in projects requiring British or European compliance. These flanges ensure compatibility and reliable connections in various piping systems across industries like oil & gas, petrochemical, water treatment, and power generation. Dipti Metal Industries acts as a leading global manufacturer and stockist for BS compliant solutions, meeting diverse market requirements, particularly for the UK and Commonwealth regions.

Dipti Metal Industries, as a top global manufacturer and supplier, offers a comprehensive range of flange types conforming to BS standards. This includes common types such as Plate (Slip-On), Weld Neck, Blind, Loose (Lap Joint), Screwed (Threaded), and Socket Weld flanges. These are manufactured with various facings like Raised Face (RF), Flat Face (FF), Male & Female (MF), Tongue & Groove (TG), and Ring Type Joint (RTJ). Our extensive manufacturing capability and inventory allow us to provide the best BS flange solution for specific piping configurations and operational needs worldwide.

As a biggest global manufacturer and stockist, Dipti Metal Industries offers BS compliant flanges and fittings in a comprehensive range of material grades suitable for demanding industrial environments. This includes Carbon Steel (e.g., BS 43A, BS 1503-161-430), Alloy Steel (e.g., BS 1503-620B), Stainless Steel (e.g., 304, 316, Duplex 2205), and exotic Nickel Alloys. Our manufactured flanges are available in numerous pressure classes, ranging from PN2.5 to PN40 (based on BS 4504), Class 150# to 2500# (based on BS 1560 / ASME B16.5 equivalents), and Table D to Table T (based on BS 10), ensuring suitability for diverse industrial applications globally. Our manufacturing capabilities ensure these demanding specifications are met, making us a top exporter for any demanding project.

BS flanges, particularly those conforming to BS 4504, are metric-based with PN (Nominal Pressure) ratings and distinct dimensional specifications compared to ASME/ANSI B16.5 flanges (which use imperial NPS and pound ratings, prevalent in North America). BS 1560, however, is a British standard that directly aligns with ASME B16.5 dimensions and pressure classes. DIN/EN (European Norm) standards often have similar PN ratings and can be dimensionally equivalent to BS 4504 in many cases, but direct interchangeability requires careful verification. Dipti Metal Industries manufactures and supplies to these distinctions and ensures that all supplied BS flanges are fully compliant and compatible with specified British, European, and international project requirements, acting as a leading international trading partner. We are adept at cross-referencing and supplying materials that meet global expectations while adhering to BS norms.
