BS 853-2:1996 - Page 2

Specification for vessels for use in heating systems. Tubular heat exchangers and storage vessels for building and industrial services | Status: Confirmed, Current

1 Scope This Part of BS 853 specifies requirements for the design, methods of construction and testing of tubular heat exchangers and storage vessels for heating, cooling and heat recovery associated with building and industrial services with limiting conditions of 2 N/mm2design pressure, 300 °C maximum and 0 °C minimum temperature using such media as water, steam, thermal oils, glycol mixtures and oil. In addition to the definitive requirements, this standard also requires the items detailed in clause 4 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.

NOTE Attention is drawn to the dangers associated with heating flammable fluids above their flash points.

Three types of heat exchangers are covered by this standard:

1. a) fixed tubeplate at each end;
2. b) U-tubes (removable tube bundle);
3. c) straight tubes with floating head at rear end (removable tube bundle).
