ASTM A36 Serrated Ring Spacer

Crafted from ASTM A36 structural carbon steel, this plain-finish serrated ring spacer caters to bespoke flange assembly needs with flexible OEM and ODM support. Boasting balanced mechanical traits and easy fabrication, its untreated serrated contact surface strengthens gasket grip and lowers flange joint leakage hazards. High-precision CNC turning and drilling position bolt holes to fit standard or special flange bolt circles. Custom dimensions, including NPS/DN, thickness, and pitch circle patterns, follow client drawings. Ideal for heavy-duty joints in oil-gas, chemical, power generation, water treatment, and broad industrial pressure-piping projects.

PLAIN FINISH SERRATED RING SPACER GRADE A36

A36 carbon steel serrated ring spacer supplied in a plain, untreated surface finish. Tail-made dimensional options cover varying outer and inner diameters and spacer thickness, supporting bespoke OEM manufacturing and ODM custom development for diverse flange assembly requirements.

1. Material: Manufactured from ASTM A36 structural carbon steel, delivering balanced mechanical performance, easy fabrication, and cost-effective performance for general pressure flange setups.

2. Surface Treatment: Raw plain finish paired with a machined serrated contact profile, enhancing interfacial grip between spacer and gasket to minimize leakage risks across flange joints.

3. Processing Technology: High-accuracy CNC turning and drilling operations, bolt hole layout precisely aligned to standard or non-standard flange bolt circle dimensions.

4. Custom Solution: Full drawing-based manufacturing service. NPS/DN ratings, wall thickness, hole quantity, and pitch circle configurations can all be modified to satisfy project-specific specifications.

Suitable for heavy-duty joint assemblies within oil & gas transmission facilities, chemical processing units, thermal power stations, municipal water treatment infrastructure, and assorted industrial pressure pipework systems.
