ISO/TC 67/SC 6/WG 8 - Process heat transfer equipment

This document specifies the requirements for the procedures and design criteria used for calculating the required wall thickness of new tubes and associated component fittings for petroleum, petrochemical and natural gas industries. These procedures are appropriate for designing tubes for service in both corrosive and non-corrosive applications. These procedures have been developed specifically for the design of refinery and related process-fired heater tubes (direct-fired, heat-absorbing tubes within enclosures). These procedures are not intended to be used for the design of external piping. This document does not give recommendations for tube retirement thickness. A technique for estimating the life remaining for a heater tube is described This document is a supplement to API 530, 7th edition (2015) including addendum 1 and addendum 2, the requirements of which are applicable with the exceptions specified in this document.

This document specifies requirements and gives recommendations for the mechanical design, material selection, fabrication, inspection, testing and preparation for shipment of shell-and-tube heat exchangers for the petroleum, petrochemical and natural gas industries. This document supplements API Std 660, 9th edition (2015), the requirements of which are applicable with the exceptions specified in this document. This document is applicable to the following types of shell-and-tube heat exchangers: heaters, condensers, coolers and reboilers. This document is not applicable to vacuum-operated steam surface condensers and feed-water heaters.

ISO 13705:2012 specifies requirements and gives recommendations for the design, materials, fabrication, inspection, testing, preparation for shipment, and erection of fired heaters, air heaters, fans and burners for general refinery service. ISO 13705:2012 is not intended to apply to the design of steam reformers or pyrolysis furnaces.

ISO 12211:2012 specifies requirements and gives recommendations for the mechanical design, materials selection, fabrication, inspection, testing and preparation for shipment of spiral plate heat exchangers for the petroleum, petrochemical and natural gas industries. ISO 12211:2012 is applicable to stand‑alone spiral plate heat exchangers and those integral with a pressure vessel.

ISO 12212:2012 specifies requirements and gives recommendations for the mechanical design, materials selection, fabrication, inspection, testing and preparation for shipment of hairpin heat exchangers for use in the petroleum, petrochemical and natural gas industries. Hairpin heat exchangers include double-pipe and multi-tube type heat exchangers.

ISO 13706:2011 gives requirements and recommendations for the design, materials, fabrication, inspection, testing and preparation for shipment of air-cooled heat exchangers for use in the petroleum, petrochemical and natural gas industries. ISO 13706:2011 is applicable to air-cooled heat exchangers with horizontal bundles, but the basic concepts can also be applied to other configurations.

ISO 25457:2008 specifies requirements and provides guidance for the selection, design, specification, operation and maintenance of flares and related combustion and mechanical components used in pressure relieving and vapour-depressurizing systems for petroleum, petrochemical and natural gas industries. Although ISO 25457:2008 is primarily intended for new flares and related equipment, it can also be used in the evaluation of existing flare facilities. Further guidance and best practices are provided for the selection, specification and mechanical details for flares and on the design, operation and maintenance of flare combustion and related equipment. ISO 25457:2008 also includes a set of data sheets, together with instructions and guidelines, for use in communicating and recording design information.

ISO 15547-2:2005 gives requirements and recommendations for the mechanical design, materials selection, fabrication, inspection, testing, and preparation for shipment of brazed aluminium plate-fin heat exchangers for use in petroleum, petrochemical and natural gas industries.

ISO 15547-1:2005 gives requirements and recommendations for the mechanical design, materials selection, fabrication, inspection, testing, and preparation for shipment of plate-and-frame heat exchangers for use in petroleum, petrochemical and natural gas industries. It is applicable to gasketed, semi-welded and welded plate-and-frame heat exchangers.

ISO 13704:2007 specifies the requirements and gives recommendations for the procedures and design criteria used for calculating the required wall thickness of new tubes and associated component fittings for petroleum-refinery heaters. These procedures are appropriate for designing tubes for service in both corrosive and non-corrosive applications. These procedures have been developed specifically for the design of refinery and related process-fired heater tubes (direct-fired, heat-absorbing tubes within enclosures). ISO 13704:2007 does not give recommendations for tube retirement thickness; Annex A describes a technique for estimating the life remaining for a heater tube. The procedures given in ISO 13704:2007 are not intended to be used for the design of external piping.

ISO 16812:2007 specifies requirements and gives recommendations for the mechanical design, material selection, fabrication, inspection, testing and preparation for shipment of shell-and-tube heat exchangers for the petroleum, petrochemical and natural gas industries. ISO 16812:2007 is applicable to the following types of shell-and-tube heat exchangers: heaters, condensers, coolers and reboilers. ISO 16812:2007 is not applicable to vacuum-operated steam surface condensers and feed-water heaters.

ISO 13706:2005 gives requirements and recommendations for the design, materials, fabrication, inspection, testing and preparation for shipment of air-cooled heat exchangers for use in the petroleum and natural gas industries. ISO 13706:2005 is applicable to air-cooled heat exchangers with horizontal bundles, but the basic concepts can also be applied to other configurations.

This International Standard specifies requirements and gives recommendations for the mechanical design, material selection, fabrication, inspection, testing and preparation for shipment of shell-and-tube heat exchangers for the petroleum and natural gas industries. This International Standard is applicable to the following types of shell-and-tube heat exchangers: heaters, condensers, coolers and reboilers. This International Standard is not applicable to vacuum-operated steam surface condensers and feed-water heaters.
