Pressure vessel details (dimensions) - Part 2: Specification for saddle supports for horizontal cylindrical pressure vessels

Requirements for dimensions and materials for saddle supports welded to stationary horizontal cylindrical pressure vessels.

This part of BS 5276, specifies dimensions and materials for saddle supports welded to stationary horizontal vessels with internal diameters between 600 mm and 3 000 mm, conforming to PD 5500 and having ellipsoidal or torispherical dished ends.

This British Standard is applicable to saddle supports welded to vessels manufactured from carbon, carbon manganese and austenitic steels having a permissible design stress not exceeding 210 N/mm2 at 50 degree C, with corresponding values at higher temperatures.

This part of BS 5276 provides data for evaluating the maximum permissible loads on shells of vessels, this data being based upon the requirements of PD 5500. Attention is drawn to PD 6497 which indicates the derivation of the basic equations and constants used in PD 5500. Maximum permissible loads for support parts are also specified.

This British Standard supersedes BS 5276-2:1983 which is withdrawn.

This Standard includes the following cross-references: BS 21, BS 449-2, PD 6497, PD 5500:2003, BS EN 10025 and BS EN 13000 (all parts).
