Merit Brass 650-32 Slip on Pipe Flange 2 in 150 Psi 316 Ss

Product Description

The MERIT BRASS 650-32 is a Grade 316 stainless steel slip-on pipe flange designed for 2-inch pipe with a 6-inch outside diameter. It is rated at 150 psi and provides a corrosion-resistant connection point in piping systems where weld-neck or threaded flanges are not required. The slip-on design allows the pipe to pass through the flange bore before welding, simplifying alignment during installation. Weighing 3.6 pounds, this flange is suited for plumbing, process piping, and industrial applications where stainless steel construction is specified for fluid compatibility or corrosion resistance.

This flange is used in residential and commercial piping systems, including process lines, water supply systems, and chemical transfer applications where Grade 316 stainless steel is required. The four-bolt-hole pattern on 4-3/4-inch bolt hole centers accepts 3/4-inch bolts, making it compatible with standard 150-class flange mating connections. Licensed plumbers, pipefitters, and industrial maintenance technicians typically install this type of flange where code or system design calls for flanged connections.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in demanding environments
• Slip-on design simplifies pipe alignment before final welding
• 150 psi pressure rating suitable for standard service piping applications
• 4-bolt-hole pattern on 4-3/4-inch bolt hole centers for standard 150-class mating flanges
• 3/4-inch bolt holes accommodate standard flange hardware
• 6-inch outside diameter on 2-inch nominal pipe size

Compatibility

Designed as an OEM-style replacement or new-installation flange for 2-inch nominal pipe size in 150-class flanged piping systems using standard bolt patterns.

Installation Notes

Installation should be performed by a licensed plumber or certified pipefitter in accordance with applicable plumbing and piping codes such as the IPC or ASME B31 standards. Shut off system pressure and drain the line completely before removing or installing any flange. Slip-on flanges require two fillet welds — one at the pipe end face and one at the bore — to achieve a full-strength joint; do not rely on bolting alone to seal the connection. Inspect the gasket seating surface and mating flange face for damage before assembly.
