Midland Industries 107067SS Threaded Flange 3 in 300 Lb

Product Description

The MIDLAND INDUSTRIES 107067SS is a 3-inch threaded flange manufactured from 316 stainless steel and rated to a 300 lb pressure class. It is designed for use in piping systems where a bolted, threaded pipe connection is required at a joint or equipment interface. This flange conforms to ANSI B16.5 dimensional standards, ensuring dimensional interchangeability with other ANSI-rated components. At 8.82 pounds, it is a solid, full-body flange suited for industrial, commercial, and trade piping applications. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

This flange is applicable in stainless steel piping systems that handle corrosive media, high-purity fluid transfer, or environments where carbon steel flanges are not suitable. The 316 stainless steel alloy provides superior corrosion resistance compared to 304 grades, making it a common choice in chemical processing, food service, marine plumbing, and HVAC hydronic systems. The threaded connection style allows for installation without welding, which is advantageous in field service and retrofit situations.

Key Features

• 316 stainless steel construction for enhanced corrosion resistance
• 3-inch threaded connection for no-weld field installation
• 300 lb pressure class rating
• Conforms to ANSI B16.5 dimensional standards
• Compatible with standard ANSI B16.5 bolt patterns and gasket dimensions

Compatibility

Designed as an ANSI B16.5-compliant threaded flange for use in 3-inch stainless steel piping systems requiring a 300 lb pressure-class rated connection.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable piping codes, including ASME B31.3 for process piping or ASME B31.9 for building services piping. Depressurize and drain the piping system fully before removing any existing flange or fitting. Thread engagement should be verified for proper fit and sealed with an approved thread sealant compatible with 316 stainless steel and the process media. Torque fasteners evenly in a cross pattern to ensure even gasket compression and a leak-free joint.
