Sealing liquefied natural gas presents a unique set of engineering challenges. At temperatures approaching −260°F, conventional sealing assumptions often break down as materials stiffen, hardware contracts, and light gases exploit even the smallest leak paths. The Cryogenic LNG Seal Design Playbook provides engineers with a practical reference for understanding how these conditions impact sealing performance and how spring-energized seals can be designed to maintain reliable contact in LNG service.
This guide walks through the key considerations for LNG sealing, including operating environment characteristics, common seal failure modes, spring and material selection, gland and hardware design, installation practices, and a practical design checklist. Whether you are specifying seals for new LNG equipment or troubleshooting leakage in existing systems, this playbook offers clear guidance to help engineers design more reliable sealing solutions for cryogenic applications.
