Hot-bolting is not permitted on our assets.

At SRJ, we see this a lot across multiple industries where the established approach in an organisation is to minimise risk by preventing hot-bolting altogether. We understand this position because hot-bolting has previously been carried out using the wrong tools or no tools to mitigate the risk of loss of containment. In the past, the safe approach was to ban the practice entirely.

However, once we explain the design, testing and verification that have gone into BoltEx® and convince the Technical Authority of a company that BoltEx® is the way forward, the next issue we typically come up against is “Our company flange management procedures don’t allow for hot-bolting.

Unsurprisingly, this is an area that SRJ can help with as well. We have written countless hot-bolting procedures as stand-alone documents or integrated into an existing flange management strategy document.

We tailor the hot-bolting procedure to the client’s existing risk management approach and ensure that it fully aligns with all principles in any pre-existing strategy. We also confirm that the hot-bolting procedure complies with global and local regulatory requirements.

Finally, we make sure that the procedure is usable to the asset workforce and agreed upon by all necessary stakeholders. We work hard for our clients to ensure that the procedure integrates seamlessly, is fit for purpose and provides safe, effective outcomes every time.
