Foreword

This part of BS 5276 has been prepared by Technical Committee PVE/1 to cover the dimensions of pressure vessel details. It supersedes BS 5276‑2:1983, which is withdrawn. This new edition of BS 5276‑2 incorporates technical changes only. It does not reflect a full review or revision of this standard, which will be undertaken in due course.

BS 5276 is published in the following Parts:

Part 1: Specification for davits for branch covers of steel vessels;
Part 2: Specification for saddle supports for horizontal cylindrical pressure vessels;
Part 4: Standardized pressure vessels.

Part 3 has been withdrawn without being replaced.

This Part 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 publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations.

1 Scope

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 °C, with corresponding values at higher temperatures.
