Compression-style fittings designed to absorb localized thermal expansion or structural settling. Testing and Quality Assurance
to ensure tensile strength and ductility [1]. Scope of the BS EN 10311 Standard Bs En 10311 Pdf
By following these recommendations, the construction industry can ensure that steel tubes and pipes used in construction projects meet the required safety, quality, and performance standards, ultimately promoting a safer and more durable built environment.
BS EN 10311 defines essential jointing methods, including butt-welded, spigot and socket, and flange joints, for low-alloy steel tubes used in water infrastructure. The standard ensures uniform, leak-proof connections, facilitating compliance with technical requirements in public and industrial piping systems. More information can be found at the official standardizing body's website. | Standard | Scope | | :--- |
To prevent misapplication, the standard explicitly outlines scenarios where it :
Screw-type connections used primarily for smaller diameter tubes. Welded Joints BS EN 10311 defines essential jointing methods, including
Verifies the seal or weld can handle peak system surges without cracking or weeping. Differential pressure and sealing validation under stress.
Note: Non-destructive testing (NDT) such as radiography or ultrasonic testing is also required for certain applications, but procedure qualification always requires destructive validation.
Includes butt-welded joints, welded spigot and socket (sleeve) joints, and welding collars.
