DIN EN ISO 13706 2012-03 PDF

Full title and description

STB DIN EN ISO 13706:2012-03 — Petroleum, petrochemical and natural gas industries — Air-cooled heat exchangers. This is the German adoption (DIN) of EN ISO 13706:2011 providing requirements and recommendations for design, materials, fabrication, inspection, testing and preparation for shipment of air-cooled heat exchangers.

Abstract

Specifies requirements and recommendations for air-cooled heat exchangers used in petroleum, petrochemical and natural gas industries. It is primarily applicable to exchangers with horizontal bundles but the principles may be applied to other configurations; covers design, materials, fabrication, inspection, testing and shipment preparation.

Scope

Applies to air-cooled heat exchangers for the petroleum, petrochemical and natural gas industries, giving requirements and recommendations for their design, materials, fabrication, inspection, testing and preparation for shipment. The standard is aimed primarily at exchangers with horizontal bundles but can be applied to other configurations as appropriate.

Key topics and requirements

• Design principles and mechanical requirements for air-cooled heat exchangers (bundle and structure design).
• Material selection and requirements, including new provisions for carbon steel in sour or wet hydrogen sulfide service (added in the 2012 DIN adoption).
• Fabrication, welding and workmanship criteria relevant to petroleum and gas industry service.
• Inspection and testing procedures, including recommended measurement procedures for airflow (informative Annex D) and measurement of noise (informative Annex E).
• Requirements for preparation for shipment and handling to protect exchanger integrity during transport.

Typical use and users

Used by engineering, procurement and construction (EPC) firms, plant designers, heat-exchanger manufacturers, third-party inspection bodies and asset owners/operators in oil, petrochemical and natural gas facilities to ensure safe, consistent and industry-aligned design, manufacture and delivery of air-cooled heat exchangers.

Related standards

EN ISO 13706:2011 / ISO 13706:2011 (international text); the DIN publication replaces DIN EN ISO 13706:2006-02. The standard is developed under ISO/TC 67 (materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries) and should be read in context with other industry standards for heat exchangers and pressure-retaining equipment.

FAQ

Q: What is this standard?

A: DIN EN ISO 13706:2012-03 is the German adoption of EN ISO 13706:2011 — an industry standard (ISO 13706:2011) that specifies requirements and recommendations for air-cooled heat exchangers used in petroleum, petrochemical and natural gas industries.

Q: What does it cover?

A: It covers design, materials, fabrication, inspection, testing and preparation for shipment of air-cooled heat exchangers, with primary application to horizontal-bundle configurations and informative annexes on airflow and noise measurement.

Q: Who typically uses it?

A: EPC contractors, mechanical and process engineers, exchanger manufacturers, quality/inspection bodies and plant owners/operators in oil, gas and petrochemical projects use this standard for procurement specifications, design verification and acceptance testing.

Q: Is it current or superseded?

A: The EN ISO text corresponds to ISO 13706:2011 (Edition 3, 2011). The DIN publication date is March 2012 and it replaced the earlier DIN EN ISO 13706:2006 edition; the ISO edition was confirmed as current in ISO’s review cycle. For project work always check for any later revisions or national amendments before use.

Q: Is it part of a series?

A: It is an ISO standard produced under ISO/TC 67 (subcommittee SC 6 for heat exchangers) and is published as EN ISO text for Europe; it relates to other standards addressing heat-exchanger design, testing and materials in the same technical area.

Q: What are the key keywords?

A: Air-cooled heat exchanger, heat exchanger design, petroleum industry, petrochemical, natural gas, fabrication, inspection, airflow measurement, noise measurement.
