Manufactured from forged carbon steel, stainless steel, or aluminum, they meet PN6 to PN40 pressure classes across DN15 to DN1200. Surface finishes, bolt patterns, and temperature ratings strictly follow BS 4504 and BS EN 1092-1 standards for global project compatibility.
Standard generic flanges often mismatch in bolt circle or gasket fit, risking leaks during pressurization. Our BS 4504 Flanges follow Table 2 and Table 4 exactly, matching OD, thickness, bolt holes, and bolt circles with no tolerance stacking.
Facing forms like B, D, and E ensure proper gasket seating to resist blowouts even at maximum PN40 pressure ratings. Forged construction from BS 1504 and machined surfaces with 3.2μm Ra roughness guarantee sealing performance even after repeated thermal cycling.

Handles pressures up to PN40 and temperatures from -10°C to +300°C, with hot-dip galvanized surfaces for long field service.
Offers gasket compatibility with BS 3381 and BS 3063 standards, minimizing leakage risks in aggressive chemical environments.
Withstands marine corrosion using BS 729 hot-dip galvanizing or ISO 1461 zinc coating, tested for 2000+ salt spray hours.
Type 01 and Type 11 flanges deliver easy assembly and maintenance access for high-flow pipe systems across DN600-DN1200 ranges.
Maintains flange integrity under cyclic heating and cooling between -50°C and +600°C for steam and condensate lines.
Custom flange marking and material certifications (BS EN 10204 3.1B) support full traceability for export-bound heavy equipment assemblies.
Incorrect flange selection can lead to sealing failures, pressure loss, and shutdowns during system operation. Our BS 4504 Flanges meet strict dimensional and material standards to prevent fitment or pressure rating mismatches.
We supply full ranges with proper certifications for carbon steel, stainless steel, and aluminum grades. Our flanges perform consistently across oil and gas, shipbuilding, chemical processing, and heavy engineering industries.

All BS 4504 flanges come with BS EN 10204 3.1B certification for full material traceability.
We also support PED 2014/68/EU Annex I documentation when projects demand pressure equipment compliance. Certificates are shipped together with the product to avoid any supply chain delays.
Yes, we machine gasket surfaces to 3.2μm Ra finish as per BS 4504 standards. This ensures proper gasket compression without leakage at rated pressure classes. Non-contact surfaces maintain a 12.5μm Ra finish for cost-effective durability.
We offer hot-dip galvanizing to BS 729 and zinc coating to BS EN ISO 1461. Sherardizing as per BS 4921 is also available for high-temperature environments. Coating selection depends on your application and operating conditions.
We manufacture bolt circles, hole sizes, and counts exactly as per BS 4504 Table 4. This ensures perfect alignment during on-site installation without any modification. Each flange undergoes inspection for bolt hole spacing and diameter accuracy.
We produce flanges from materials specified in BS 1501 and BS 1470 standards. Pressure ratings from PN6 to PN40 are verified through dimensional and material control.
Temperature performance is supported by both base material properties and surface treatment.
