Macomb Group Approved 340-060-000 Threaded Flange 6 Inch

Product Description

The MACOMB GROUP APPROVED 340-060-000 is a Class 300 threaded flange designed for high-pressure piping systems in industrial, commercial, and mechanical applications. Built from forged steel meeting ASTM A105 and ASME SA105 material standards, this flange handles pressures up to 740 psi across a temperature range of -20 to 100 degrees F. The raised face seating surface and FNPT connection type make it compatible with standard threaded pipe assemblies. Nominal size is 6 inches. Installation is performed by licensed pipefitters and mechanical contractors following ASME B16.5 dimensional and pressure-temperature standards.

This flange is suited for use in industrial process piping, HVAC mechanical rooms, water and steam distribution systems, and commercial plumbing infrastructure where a Class 300 pressure rating is required. The threaded FNPT connection allows installation without welding, making it a practical choice for field service and retrofit work. The raised face design ensures a reliable seal with standard spiral wound or ring gaskets at the flange joint.

Compatibility

Designed for use in Class 300 flanged piping assemblies with 6-inch nominal pipe size, conforming to ASME B16.5 pressure-temperature ratings and bolt pattern requirements.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable codes including ASME B31.1 or B31.3 as required by the system. Depressurize and isolate the piping system completely before beginning flange assembly or disassembly. Verify gasket type, bolt grade, and torque sequence are appropriate for the Class 300 service conditions per applicable piping specifications. Thread engagement should be confirmed prior to final bolt-up to ensure proper alignment and seal integrity.
