FLG BS&B 4" Flange Mount Burst Disc — 10 PSIG

What pressure, flow and temperature is it rated for?

This unit is rated at 10 PSIG burst pressure. Flow capacity and temperature rating are not specified in the listing; you'll need to request the specific BS&B model number or catalog data sheet from the seller to determine these values. Burst discs are typically selected based on rupture pressure and flow coefficient (Kd), which varies significantly by design type and size.

What materials are the wetted parts?

The listing specifies 14.0 stainless steel construction but does not detail which components this refers to or whether seals and gaskets are included. Typical BS&B flange mount sets include the rupture disc, holder, and process gaskets; you should request a complete material specification and confirm what's included in this set.

What should I inspect before putting it into service?

Verify the disc is undamaged with no dents, scores, or corrosion on the rupture surface, and confirm the holder flanges are flat and undistorted. Check that all nameplates and stamps are legible to confirm the rated burst pressure, and ensure gaskets appropriate for your service are available. Burst discs are single-use devices that cannot be tested without destroying them, so visual inspection and documentation review are critical before installation.
