Merit Brass 450-24 Slip on Pipe Flange 1-1/2 in 150 Psi Ss 304

Product Description

The MERIT BRASS 450-24 is a slip-on pipe flange designed for 1-1/2 inch pipe with a 5 inch outside diameter. Manufactured from Grade 304 stainless steel, it is rated to 150 psi and suited for piping systems where corrosion resistance is a priority. The circular flange features four bolt holes spaced 3-7/8 inches across bolt hole centers, with each bolt hole measuring 5/8 inch. Plumbers, pipefitters, and mechanical contractors use this type of flange to connect pipe sections to valves, equipment, or other flanged components without threading or welding the pipe end.

This flange is appropriate for residential and commercial plumbing, process piping, and mechanical systems where 1-1/2 inch stainless steel pipe is specified. The slip-on design allows the pipe to pass through the flange bore before welding, simplifying alignment during installation. Grade 304 stainless steel construction makes it a common choice in wet, corrosive, or sanitary environments where carbon steel flanges are not suitable.

Key Features

• Slip-on connection type allows pipe insertion before final weld, easing field alignment
• Grade 304 stainless steel construction for corrosion resistance in wet or chemical-exposure environments
• 150 psi pressure rating suitable for standard-service piping applications
• Four bolt holes at 3-7/8 inch bolt hole center spacing for standard flange bolt patterns
• 5/8 inch bolt hole diameter accommodates standard flange fasteners
• Circular profile with 5 inch outside diameter for 1-1/2 inch nominal pipe size

Compatibility

Designed as an OEM-style replacement or new-installation slip-on flange for 1-1/2 inch nominal pipe size piping systems rated to 150 psi.

Installation Notes

Slip-on flanges are installed by licensed pipefitters or plumbers and typically require fillet welding at both the face and bore of the flange to the pipe. Shut down the piping system and verify zero pressure before beginning any flange work. Follow applicable codes such as ASME B31.1 or B31.3 for pipe welding and flange assembly procedures. Inspect mating flange faces and use an appropriate gasket rated for the service conditions before bolting up.
