Forged Steel Spacer Ring Flanges Manufacturer, Exporter & Supplier

About DIPTI® Spacer Flanges

DIPTI Metal Industries, founded by Mr. Kumpsingh Rajput, is a leading ISO-certified manufacturer, stockist, and global exporter of forged steel spacer ring flanges. With advanced forging and machining facilities in Mumbai, we deliver high-performance spacer flanges engineered to meet stringent ASME, EN, DIN, BS, JIS, and ISO standards.

What Are Spacer Ring Flanges?

Spacer ring flanges, also known as ring spacers, are precision-forged components inserted between two flanges in a piping system. Their purpose is to maintain alignment and spacing, facilitate maintenance, and enable safe flow control without dismantling the line.

Unlike conventional blinds, spacer flanges allow smooth transitions between operation and inspection. They are widely preferred for isolation, pipeline maintenance, cryogenic service, and thermal expansion management.

Key Features & Benefits

• Accurate Gap Control: Maintains precise distance between mating flanges.

• Leak Prevention: Reduces bending stress and ensures tight sealing.

• Easy Installation: Bolted directly between flanges without welding.

• Versatile Design: Available in Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ).

• Material Flexibility: Manufactured in stainless, duplex, carbon, alloy, nickel alloys, titanium & copper-nickel.

• Global Compliance: Supplied to oil & gas, petrochemical, chemical, power generation, water treatment, and marine sectors.
