Manufacturer, Exporter & Stockist — Weld Neck, Slip On, Blind, Socket Weld, Lap Joint & Threaded
Steel Inox Pvt. Ltd. manufactures a full range of stainless steel flanges for strength, precision, and leak-proof performance in critical piping systems.
Manufactured to ASTM A182, ASME SA182, ASME B16.5, B16.47, EN 1092-1, and API 605. Dimensional accuracy and complete traceability assured.
For high-pressure/temperature with tapered hub for even stress distribution.
Cost-effective for moderate-pressure systems — welded on both sides.
Seal piping ends and pressure vessel openings — exact thickness specs.
Small-diameter, high-pressure piping — smooth bore, excellent fatigue resistance.
Used with stub ends for easy alignment and frequent dismantling.
No welding required — for low-pressure and explosive atmosphere applications.
