One-Minute Overview

Slip on flange in SS 321 stainless steel, 2 inch, 300LB, raised face.
Forged and dimensioned to ANSI B16.5 for a dependable bolt-up.
SS 321 grade is specified for aggressive fluids and harsh environments.
Fixed to pipe or equipment by a fillet weld for quick installation.

The SS321 slip on flange pairs a slip on profile with the SS 321 stainless steel grade. This 2 inch, 300LB flange carries a raised face and is forged to ANSI B16.5 dimensions. SS 321 is the grade specified for aggressive fluids and harsh environments, so the flange holds up where corrosion is the daily worry. It is mounted by a fillet weld directly to the pipe or the equipment nozzle, keeping installation quick on site.

Name: SS321 Slip On Flange
Size: 2"
Pressure: 300LB
Material: SS 321
Flange Face: RF
Standard: ANSI B16.5

A slip on flange is forgiving to align and quick to weld: slip it over the pipe, tack it square, and run the fillet weld inside the bore and around the hub. The 300LB class suits higher-pressure lines than Class 150 while keeping the same bolt-up simplicity. Choose SS 321 when the media is aggressive or the environment harsh; for mild duty a basic grade would do, but the 321 grade buys margin against corrosion. Match the mating flange class, bolt circle and gasket style before ordering.

FAQ

Q1. What does SS 321 actually buy me over a normal stainless flange?

The material. This flange is forged from SS 321 stainless steel, which is picked for aggressive fluids and harsh environments where corrosion is the main worry. Dimensions still follow ANSI B16.5 and the class is 300LB, so the upgrade is about the steel, not the fit.

Q2. Which standard and pressure class apply to this flange?

The flange is dimensioned to ANSI B16.5 and rated 300LB in the 2 inch size, with a raised face for gasket seating. Bolt circle and drilling follow the standard, so it mates with other ANSI B16.5 Class 300 flanges. Confirm the gasket suits the service before ordering.

Q3. Can I weld it on with my eyes closed?

Please keep them open. A slip on flange takes a fillet weld inside the bore and around the hub, and the fit-up still wants a square, clean joint. The forgivable part is alignment; the unforgivable part is skipping the weld inspection or using the wrong filler for SS 321.

Q4. How long will production take?

Standard sizes are typically ready within 30 days, and in-stock items ship immediately. Larger or custom orders get a confirmed date per order, because the schedule depends on quantity, material, the bolt pattern you specify, and how busy production is at the moment you order.
