ISO 16812 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 supplements API Std 660, 9th edition (2015), the requirements of which are applicable with the exceptions specified in ISO 16812. ISO 16812 is applicable to the following types of shell-and-tube heat exchangers: heaters, condensers, coolers and reboilers.
Note: ISO 16812 is not applicable to vacuum-operated steam surface condensers and feed-water heaters.
ISO 16812 on the shell-and-tube heat exchangers is useful to:
Shell-and-tube heat exchangers have the ability to transfer large amounts of heat in relatively low cost, serviceable designs. API Std 660, 9th edition (2015) specifies requirements for shell-and-tube heat exchangers, however with new developments a large section of that document has been deemed outdated.
ISO 16812 provides you with references to the appropriate documents for the various sections of API Std 660. This helps you to use the current and accepted practices for the shipment of shell-and-tube heat exchangers.
