Lot of 4 Fike 12" 300 ANSI FSR Rupture Disc Holders (316 SST) — New Surplus with MTRs

Item Overview

This listing is for four (4) massive, brand new Fike FSR Rupture Disc Holders. These are heavy-duty, industrial-grade safety components designed to securely hold rupture discs between standard pipe flanges in high-pressure process piping.

These specific holders are 12-inch (DN300) size, rated for Class 300 ANSI flanges, and are constructed entirely from premium 316 Stainless Steel. They were manufactured in the USA and shipped directly to Syncrude Canada Ltd. (a major oil sands operator) but were never installed. They remain in their original factory wooden crate.

Crucially, this lot includes the original EN 10204 Type 3.1 Material Test Reports (MTRs) from McInnes Rolled Rings, proving the exact chemical composition and heat treatment of the steel. This paperwork is mandatory for installation in most refinery, petrochemical, and oil & gas facilities.

Application

Rupture disc holders are installed in critical process piping to provide a secure, leak-tight seal for rupture discs. The FSR (Forward Scored Rupture) series is designed for high-performance pressure relief in demanding environments, such as refineries, chemical plants, and offshore platforms. The NACE MR0175 compliance means these holders are certified for use in sour gas (H2S) environments.
