29、007 without any modification. DIN EN ISO 10438-4:2010-08 EN ISO 10438-4:2007 (E) 4 Introduction This International Standard was developed jointly with API 614, 5th edition. ISO 10438 is divided into four parts corresponding to the four chapters of API 614. Users of this part of ISO 10438 should be a
30、ware that further or differing requirements might be needed for individual applications. This part of ISO 10438 is not intended to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. This may be particularly
31、appropriate where there is innovative or developing technology. Where an alternative is offered, the vendor should identify any variations from this part of ISO 10438 and provide details. It is intended that this part of ISO 10438 be used in conjunction with 10438-1. This part of ISO 10438 requires
32、the purchaser to specify certain details and features. A bullet () at the beginning of a clause or subclause indicates that either a decision is required or further information is to be provided by the purchaser. This information or decision should be indicated on the datasheet(s); otherwise it shou
33、ld be stated in the quotation request or in the order. In this International Standard, US customary (USC) units are included in brackets for information. DIN EN ISO 10438-4:2010-08 EN ISO 10438-4:2007 (E) 5 1 Scope This part of ISO 10438 in conjunction with ISO 10438-1 specifies requirements for sup
34、port systems for self-acting gas seals (dry gas seals), for example as described in ISO 10439 and ISO 10440-1. These systems can serve equipment such as compressors, gears, pumps and drivers. NOTE For the purposes of this statement of scope, API 617 is equivalent to ISO 10439 and API 619 is equivale
35、nt to ISO 10440-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 104

38、ent, the terms, abbreviated terms and definitions given in ISO 10438-1 apply. DIN EN ISO 10438-4:2010-08 EN ISO 10438-4:2007 (E) 6 4 General 4.1 System selection Datasheets for system specifications are provided in Annex A. Annex B provides schemas of typical system components and diagrams of typica
39、l, complete dry gas seal support systems and modules. These schemas and diagrams illustrate the general philosophy and requirements of this part of ISO 10438 and are included to assist the purchaser in the selection of an appropriate system. The purchaser and the vendor shall mutually agree upon an
40、acceptable system. Annex C provides an inspector checklist of typical items reviewed by the purchaser. 4.2 Basic design 4.2.1 The equipment (including auxiliaries) covered by this part of ISO 10438 shall be designed and constructed for a minimum service life of 20 years and at least 5 years of unint
41、errupted operation. NOTE It is recognized that this is a design criterion. z 4.2.2 If specified, the purchaser may specify the vendor responsible for each portion of the design, scope of supply, installation and performance of the dry gas seal system. If the purchaser is not the end user, then the e
42、nd user shall approve the vendors specified. z 4.2.3 The purchaser shall specify the equipments normal operating point and all other operating points. Other parameters required for the design of the seal support system, such as gas composition, maximum and minimum flare pressure, maximum and minimum
43、 sealing pressure and settle-out pressure shall also be specified. 4.2.4 Unless otherwise specified, the lube-oil console and the dry gas seal module shall be mounted on separate skids. 4.2.5 The dry gas seal system shall be designed to serve the full range of equipment operating conditions specifie
44、d. These conditions may include but are not limited to the following: a) settle-out pressures; b) process relief-valve settings; c) shop test and field run-ins; d) start-up conditions; e) gas composition. NOTE This requires a detailed system review with the equipment suppliers, purchaser and owner,
45、and is normally finalized at the coordination meeting. 4.2.6 Control systems shall provide adequate gas velocity across the labyrinths at all clearances, including minimum labyrinth clearance to twice the maximum design labyrinth clearance to prevent migration of contaminents from the process gas. N
46、OTE In a flow-control system, velocity across the labyrinths decreases as clearances increase. 4.2.7 All gas streams (including alternate, backup, start-up sources) into the seal shall be provided at a temperature of at least 20 K (35 R) above their dew point in order to preclude the possibility of
47、liquid entering the dry gas seal. DIN EN ISO 10438-4:2010-08 EN ISO 10438-4:2007 (E) 7 NOTE 1 On some systems, the discharge temperature of the compressor gas stream might not provide this dew-point margin. NOTE 2 In some cases, this can require heaters and/or heat tracing by the owner. The dew-poin
48、t margin shall be maintained throughout the seal and not just at the supply connections. In some cases, alternate gases to the process gas should be considered for start-up or dew-point reasons. z 4.2.8 If specified, additional provision for seal-gas conditioning as specified by the purchaser shall
49、be furnished. NOTE Gas conditioning can involve heat tracing, alternate seal-gas sources, coalescing filters, or other provisions. 4.2.9 Valved vents, drains and piping shall be furnished to permit draining, cleaning and refilling of idle components, such as filter elements, while the equipment is in operation. 4.2.10 Seal-gas module piping shall be arranged such that it can be manually drained prior to start-up to avoid the possibility of c
