Weld Neck Flanges

At Kriloha Ltd., we supply Weld Neck Flanges, one of the most widely used flange types in high-pressure oilfield and industrial applications. Weld neck flanges feature a long tapered hub that distributes stress evenly, reducing fatigue and improving pressure containment. Manufactured from forged alloy steels, Kriloha weld neck flanges are designed for severe service conditions, offering exceptional strength, leak prevention, and durability. Applications include wellhead systems, high-pressure pipelines, refinery units, offshore platforms, and petrochemical plants. Their robust design makes them ideal for cyclic loading and temperature fluctuations. Every weld neck flange is tested for hydrostatic performance, weld integrity, and dimensional compliance, meeting API 6A and ANSI B16.5 standards. As a supplier and facilitator, Kriloha Ltd. offers custom bore machining, corrosion-resistant overlays, and exotic alloy options, making our weld neck flanges the preferred choice for critical pressure-containing systems.
