This document provides a listing of available Swagelok hose and flexible tubing styles and associated data and indicates whether each is acceptable for code construction at LANL when used within its limits
This document lists Swagelok flex hoses approved for use in LANL’s pressure safety systems under ASME B31.3 standards. It includes hose series, manufacturer ratings, burst test data, and LANL-wide approval status. Each hose type is evaluated for compliance with code requirements and temperature-dependent pressure ratings.
The document references Swagelok’s historical brands (Whitey, Cajon, Nupro) and provides guidance on component standards such as ASTM F423 and BSI BS 6501. It also notes which standards are superseded and includes references to specific annexes (A323.2) for additional requirements.
