BS EN 1708-3:2012

What is BS EN 1708-3 - Wedding clad, buttered, and lined pressurized components about?

The EN 1708 series is a European Standard that discusses various requirements of basic weld joint details in steel.

BS EN 1708-3 complements EN 1708-1 with regard to applications in the industrial, chemical, and pharmaceutical sectors. It specifies established examples of how to construct claddings, linings, dissimilar joints, and complex connections relevant to the welding technology and with regard to pressurized components. In the following text therefore the term pressurized components will be used.

BS EN 1708-3 does not override conditions on dimensioning of welded joints regarding strength. It is to be applied in accordance with the specified application limits for pressurized components subject to compression stress with bearing wall thicknesses ≤ 30 mm. This limit is chosen for structural reasons and not for the heat treatment that may be required. The wall thickness limit applies to butt welds in the bearing vessel wall only and does not apply to flanges, torispherical heads, flat ends, or other similar parts.

Appropriate national regulations and corresponding design specifications are to be followed when selecting design examples as well as, if applicable, different, or further requirements.

• This European Standard applies to the following types of steel
• Non alloyed steels with a minimum tensile strength of Rm ≤ 450 MPa
• P295GH and 16Mo3 according to EN 10028-2
• Fine-grain steels according to EN 10028-3 with a minimum yield point ReL ≤ 355 MPa
• Austenitic steels according to EN 10028-7
