Pd 5500 63.pdf

Pd 5500 63.pdf is a document that contains the specification for unfired pressure vessels, which are containers that hold fluids under pressure without being exposed to combustion or other chemical reactions. Unfired pressure vessels are used in various industries, such as oil and gas, chemical, pharmaceutical, food and beverage, and power generation. They can have different shapes, sizes, and materials, depending on their design and function.

The document is based on PD 5500:2021+A2:2022, which is the latest edition of the UK's national pressure vessels code. PD 5500 is published by BSI, the British Standards Institution, and is updated every three years with annual amendments. PD 5500 specifies the requirements for the design, manufacture, inspection, and testing of unfired pressure vessels made from carbon, ferritic alloy, and austenitic steels. It also includes material supplements containing requirements for vessels made from aluminium, copper, nickel, titanium, and duplex.

The document covers the following topics:

  • General information, such as scope, interpretation, definitions, responsibilities, and information exchange between the purchaser and the manufacturer.

  • Material selection and properties, such as nominal design strength, corrosion allowance, and low temperature applications.

  • Design principles and criteria, such as construction categories, design stresses, design pressure and temperature, thermal loads, wind and earthquake loads, and corrosion protection.

  • Design of specific components, such as cylindrical and spherical shells, dished ends, cones and conical ends, flat ends and flat plates, openings and nozzle connections, spherically domed and bolted ends, and vessels under external pressure.

  • Fabrication and welding requirements, such as welding procedures and qualifications, weld preparations and details, weld repairs and rework, post-weld heat treatment, non-destructive testing methods and acceptance criteria.

  • Inspection and testing requirements, such as inspection plans and records, hydrostatic testing methods and pressures, pneumatic testing methods and pressures, leak testing methods and pressures.

  • Documentation requirements, such as data reports and certificates of conformity.

The document is intended to provide guidance for the design and assessment of unfired pressure vessels in accordance with the relevant regulations and standards. It is not a substitute for the application of professional judgement by competent engineers. The document also does not cover all aspects of unfired pressure vessel design and manufacture. For example, it does not address issues such as fatigue analysis, fire resistance, or vibration analysis. These topics may require additional considerations or references to other standards or codes.

The document is available in PDF format from the BSI website. It can be purchased as a single document or as part of a subscription service that provides access to all editions and amendments of PD 5500. The document is also compatible with other BSI standards publications on related topics, such as BS EN 13480 on metallic industrial piping, BS EN ISO 15614 on specification and qualification of welding procedures for metallic materials, or BS EN ISO 3834 on quality requirements for fusion welding of metallic materials.

Pd 5500 63.pdf is a useful resource for engineers, designers, manufacturers, inspectors, regulators, and users of unfired pressure vessels. It provides a comprehensive set of requirements and best practices for ensuring the safety and performance of these important industrial components.
