One-Minute Overview

Socket weld flange in SS 316 stainless steel, 2 inch, 300LB, raised face.
Forged body dimensioned to ASME B16.5 for high-temperature and high-pressure service.
SS 316 grade resists corrosion in aggressive process media.
Quick to install and disassemble in refinery and chemical plant piping.

The SS 316 socket weld flange puts a 2 inch pipe into a machined socket and locks it with a fillet weld, keeping the bore smooth and the joint strong. Forged from SS 316 stainless steel, it shrugs off corrosive media that would attack lesser grades, while the 300LB raised-face rating covers high-temperature and high-pressure duty carrying flammable or explosive gas and liquid.

Name: SS 316 SW Flange
Size: 2"
Pressure: 300LB
Material: SS 316
Flange Face: RF
Process Method: Forged
Standard: ASME B16.5

The 316 grade keeps its corrosion resistance in chemical plants and oil refineries where process streams are anything but friendly. At 2 inch, a socket weld makes sense: the pipe seats in the socket, the hub controls alignment, and the fillet weld finishes the job without the precision fit-up of a butt weld. Crews can install and disassemble the flange quickly during turnarounds, and the raised face holds a tight seal at 300LB through thermal cycles. Match the stud bolting to the adjoining 300LB flange and tighten evenly to the gasket guidance.

FAQ

Q1. Why pick SS 316 for a socket weld flange?

Because some lines are mean. SS 316 keeps its corrosion resistance in aggressive process media, so the flange lasts longer in refineries and chemical plants where a plain grade would pit and weep. Add the forged body and the 300LB raised face, and you get a joint that stays tight.

Q2. So it survives hot, high-pressure duty? Dare I ask what it carries?

You may ask — it is rated for exactly that. High temperature, high pressure, flammable or explosive gas and liquid are its normal workday. The forged body takes the load and the RF face keeps the seal, which is the whole point when the alternative is a leak.

Q3. What does ASME B16.5 cover on this flange?

The dimensions, the 300LB pressure class and the raised-face configuration follow ASME B16.5, so the flange mates with standard 300LB fittings and gaskets. The SS 316 material and the socket weld end are built inside that same framework for high-temperature, high-pressure service.

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.
