Asc Engineered Solutions 308500404 Cast Iron Companion Flange

Product Description

The ASC ENGINEERED SOLUTIONS 308500404 is a black cast iron companion flange rated for extra heavy (XH) 250 service. It features a 2.5-inch bore with a 7.5-inch outer diameter, built to handle demanding industrial and commercial piping applications. Cast iron construction provides durability under high-pressure and high-temperature conditions. The black coating finish resists corrosion and surface oxidation. Licensed plumbers and pipefitters install this flange as part of flanged joint assemblies in piping systems where a mating companion flange is required to complete a bolted connection.

This companion flange is suited for use in commercial and industrial piping systems requiring extra heavy-duty flanged connections. It is commonly installed in steam, water, and general service pipelines operating under elevated pressure conditions. The XH 250 pressure class designation makes it appropriate for system configurations that exceed standard-weight flange ratings. Domestic manufacture supports traceability requirements on regulated job sites and specification-driven projects.

Key Features

• Cast iron construction rated for extra heavy (XH) 250 service class
• 2.5-inch bore with 7.5-inch outer diameter for standard flanged joint assembly
• Black coating finish for corrosion and surface oxidation resistance
• Companion flange design mates with opposing flange to complete bolted connections
• Domestically manufactured to support traceability and specification compliance

Compatibility

Designed as an OEM-style replacement and standard-service companion flange for extra heavy 250 class flanged piping assemblies with a 2.5-inch pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and piping codes. Depressurize and isolate the piping system fully before disassembling any flanged joint. Use appropriate flange gaskets and fasteners rated to match the XH 250 pressure class. Do not overtighten bolts unevenly; follow a cross-pattern torque sequence to ensure uniform gasket compression and a leak-free joint.
