Petroleum, petrochemical and natural gas industries - Dry gas sealing systems for axial, centrifugal, and rotary screw compressors and expanders (ISO 6368:2021)

This document is applicable to dry gas sealing systems for axial, centrifugal, and rotary screw compressors and expanders as described in ISO 10439 (all parts), ISO 10440-1 and ISO 10440-2. Although intended for use primarily in oil refineries, it is also applicable to petrochemical facilities, gas plants, liquefied natural gas (LNG) facilities and oil and gas production facilities. The information provided is designed to aid in the selection of the system that is most appropriate for the risks and circumstances involved in various installations.
This document does not apply to other types of shaft seals such as clearance seals, restrictive ring seals or oil seals.
This document is a supplement to API Std 692, 1st edition (2018), the requirements of which are applicable with the exceptions specified in this document.

Petrokemična industrija ter industrija za predelavo nafte in zemeljskega plina - Tesnilni sistemi s suhim plinom za aksialne, centrifugalne in rotacijske vijačne kompresorje in ekspanderje (ISO 6368:2021)

Ta dokument se uporablja za tesnilne sisteme s suhim plinom za aksialne, centrifugalne ter rotacijske vijačne kompresorje in ekspanderje, kot je opisano v standardih ISO 10439 (vsi deli), ISO 10440-1 in ISO 10440-2. Čeprav je prvotno namenjen uporabi v naftnih rafinerijah, se lahko uporablja tudi v petrokemičnih obratih, plinarnah, obratih z utekočinjenim zemeljskim plinom (LNG) in obratih za proizvajanje plina. Podane informacije so namenjene za pomoč pri izbiri sistema, ki je najprimernejši za tveganja in okoliščine v različnih namestitvah. Ta dokument se ne uporablja za druge vrste tesnil za gredi, kot so labirintna, omejevalna ali oljna tesnila. Ta dokument dopolnjuje standard API 692, prvo izdajo (2018), katerega zahteve se uporabljajo za izjeme, določene v tem dokumentu.
