One-Minute Overview

Forged A182 F304 blind flange that blocks or temporarily closes a pipeline end.
2 inch, 150LB, raised face for a tight gasket seal.
SS 304 stainless steel body resists corrosion and reduces maintenance.
Good fit for chemical, petrochemical and food processing lines.

This A182 F304 blind flange seals a 2 inch line with a solid forged disk rated 150LB. The raised face concentrates bolt load on the gasket, while the SS 304 stainless body keeps rust and chemical attack at bay. It is the part you bolt on when a pipeline end must be blocked outright or held closed for a shutdown window.

During maintenance the blind gives positive isolation: crews can open a section downstream while the rest of the plant keeps running. The forged body handles repeated bolt-up cycles, and the 304 grade tolerates the wash-downs and process chemicals common in food and chemical plants. Match stud bolting to the flange class, tighten in a star pattern, and inspect the face each time the joint is broken. Where the line is pigged or cleaned in place, check the blind thickness and facing against your procedure so the closure does not trap residue.

FAQ

Q1. How does this blind help during a shutdown?

It gives a positive, visible block at the isolation point. The solid forged disk stops flow completely, so crews can open downstream piping without leaning on a valve that might pass. With a proper gasket and class-matching bolting, the pressure boundary stays sound while work goes on.

Q2. What distinguishes this A182 F304 blind from other 2 inch blinds?

The flange is a 2 inch 150LB forged blind with a raised face, material SS 304 stainless steel, carrying the A182 F304 forging designation. Select it to match your material callout, verify the face is clean and flat before bolting, and confirm the pressure rating suits the service.

Q3. Can I use this blind as a permanent pipe cap?

That is exactly what it is: a bolted end closure for a pipeline. Blind flanges stay on as permanent caps or wait at future tie-in points until the next branch is needed. Treat it like any pressure part, with the correct gasket and bolting, no improvising with mismatched nuts.

Q4. What payment terms do you accept?

T/T, L/C at sight and other internationally accepted terms. The exact terms are agreed with you before production starts, because the payment schedule has to match the order value, the shipping method and the delivery schedule you need — which is also why we confirm them up front rather than after shipment.
