Merit Brass A653L-96 Socket Weld Pipe Flange 6 in SS316

Product Description

The MERIT BRASS A653L-96 is a socket weld pipe flange designed for 6-inch pipe with an 11-inch outside diameter. Manufactured from Grade 316/316L stainless steel, this flange is built for corrosion-resistant piping systems where weld-in fittings are required. It carries an 8-bolt-hole pattern with bolt holes centered 9.5 inches across and individual holes measuring 0.875 inches in diameter. Rated at 150 psi, it is suited for moderate-pressure process and mechanical piping applications. A licensed pipefitter or plumber typically handles socket weld flange installation in commercial and industrial settings.

This flange fits 6-inch nominal pipe and is used in piping systems that require a permanent, full-penetration weld connection at the flange face. Typical applications include process piping, chemical handling lines, marine installations, and food-grade systems where 316 or 316L stainless steel is specified for chloride or corrosion resistance. The socket weld style accommodates smaller bore pipe ends inserted into the socket before welding, producing a smooth internal flow path. It is sold individually.

Key Features

• Grade 316/316L stainless steel construction for superior corrosion resistance
• 150 psi pressure rating suitable for standard-service piping systems
• 11-inch outside diameter with 8 evenly spaced bolt holes
• 9.5-inch bolt hole circle diameter with 0.875-inch bolt holes
• Socket weld connection style for secure, full-penetration weld joints
• Circular profile for standard raised-face or flat-face flange mating

Compatibility

Designed as an OEM-style socket weld pipe flange for 6-inch nominal pipe in 150-class stainless steel piping systems where Grade 316 or 316L material is specified.

Installation Notes

Socket weld flanges are installed by licensed pipefitters or journeyman welders and must be welded in accordance with applicable ASME B31.3 or B31.1 piping code requirements. Depressurize and drain the piping system completely before removing any existing flanges or fittings. Insert the pipe end into the socket to the proper gap depth per code before tack-welding and completing the fillet weld. Verify flange face alignment and bolt hole orientation before final weld passes to avoid stress on mated components.
