What is PD 6550-4 – Design of heat exchanger tubesheets about?
PD 6550 is Published Document that is an explanatory supplement to BS 5500:1988.
PD 6550 has been written to assist both the newcomer to pressure vessel design and the experienced vessel designer. PD 6550 describes the background to BS 5500 and its theoretical basis in design. Answers are given to many of the questions that are asked about the detailed and complex rules and requirements concerning the design of pressure vessels to BS 5500.
PD 6550-4 is the fourth part of the document that discusses the design of heat exchanger tube sheets used for unfired fusion welded pressure vessels.
Who is PD 6550-4 – Design of heat exchanger tubesheets for?
PD 6550-4 on the design of heat exchanger tubesheets is useful for:
- Pressure vessel manufacturer
- Product designers
- National authorities
- Regulatory bodies
- Users of BS 5500
- Certification bodies
Why should you use PD 6550-4 – Design of heat exchanger tubesheets?
In BS 5500, heat exchangers are divided into those with floating heads or U-tubes and those with fixed tube sheets. The type of exchanger chosen for a duty depends on the process requirements and on the limitations imposed by materials, mechanical design, and cost.
In all exchangers, the tube sheet forms an important structural component. It is an essential part of the barrier between shell side and tube side fluids. It must withstand the pressures of these fluids and must be strong enough to ensure that the numerous tubes to tube sheet attachments are reliable in service and remain free from leaks.
PD 6550-4 is your companion guide on understanding the practicality and technical expertise behind the design of heat exchanger tube sheets for pressure vessels.
