One-Minute Overview

Solid stainless steel disk that blocks a 2 inch flange joint.
Raised face (RF), 150LB class, 2 inch size, forged construction.
Corrosion-resistant body suits process lines and outdoor exposure.
Closes a pipeline end for good, or just until the job is done.

The RF blind flange closes a 2 inch piping joint with a solid plate. Forged stainless steel gives the part the corrosion resistance a pressure-boundary part needs, and the raised face (RF) is the usual sealing surface for this class of joint. Use it where the end of a line must be blocked - permanently, or temporarily while work is done further down the line.

A blind flange earns its keep at dead ends, at branches reserved for later tie-in, and across valves during maintenance, where a section has to be opened without draining everything around it. Stainless steel resists rust and oxidation, so the sealing face stays true and maintenance costs stay down over repeated shutdowns. Select the gasket for the media, bolt with fasteners of the matching class, and tighten in a star pattern. Check the mating flange face before ordering so RF lines up with the joint on site.

FAQ

Q1. What does the RF designation mean on this blind flange?

RF means raised face: the sealing surface stands proud of the bolting circle, which is the usual arrangement for steel flange joints of this class. The gasket sits on that raised ring, so the clamping load concentrates where the seal actually happens and the joint stays tight.

Q2. Where would I use a 2 inch blind like this?

At the end of a small-bore line, at a branch waiting for a future tie-in, or across a valve while maintenance is done downstream. Anywhere the line must be blocked - for good or just for the shift - the blind bolts in and gives a visible, positive closure.

Q3. Is stainless steel overkill for a simple blanking plate?

Only until the first time a carbon steel plate rusts to the gasket. The forged stainless body resists corrosion and oxidation, keeps the sealing face smooth through repeated shutdowns, and cuts the maintenance a corroded blind would demand. Call it cheap insurance for the joint.

Q4. How long does production take?

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