Unfired pressure vessels - Part 3: Design
Design method for flat ends when fatigue is not the controlling factor; the present method in Clause 10 makes no distinction and may may be too conservative in these cases.

Replace the whole of Clause 10 with the following text:
10 Flat ends
10.1 Purpose
10.1.1 This clause specifies methods for determining the thickness of circular and non-circular unstayed flat
ends under pressure and for providing adequate reinforcement for openings fitted in such ends. Loads other
than pressure are not considered.
NOTE 1 For welded flat ends, the method takes into account the stresses caused by the junction forces and moments.
For bolted flat ends, the method takes into account the stresses caused by the forces and moments due to the flange and
bolting.
NOTE 2 For the design of vessels of rectangular cross-section, refer to Clause 15.
10.1.2 Stayed plates, i.e. plates supported by braces, stay bars or stay tubes, are not considered in this
clause.
NOTE Stayed plates may be calculated using the formulae and methods of the European Standard for Shell Boilers
(see EN 12953) with the nominal design stresses of this standard.
These rules do not apply to heat exchanger tubesheets, which are covered by Clause 13.
10.1.3 These rules do not apply to self-sealing covers, i.e. to covers where compression of the gasket is
obtained through the action of internal pressure and which are equipped with a bolting-up device.
