1、TECHNICAL SPECIFICATION RECIPROCATING POSITIVE DISPLACEMENT PUMPS AND METERING PUMPS DEP 31.29.12.30-Gen. July 1983 (DEP Circular 19/97 has been incorporated) DESIGN AND ENGINEERING PRACTICE USED BY COMPANIES OF THE ROYAL DUTCH/SHELL GROUP This document is confidential. Neither the whole nor any par
2、t of this document may be disclosed to any third party without the prior written consent of Shell Internationale Petroleum Maatschappij B.V., The Hague, the Netherlands. The copyright of this document is vested in Shell Internationale Petroleum Maatschappij B.V., The Hague, the Netherlands. All righ

Neither the whole nor any part of this document may be reproduced, stored in any retrieval system or transmitted in any form or by any means (electronic, mechanical, reprographic, recording or otherwise) without the prior written consent of the copyright owner. PREFACE DEP (Design and E
4、ngineering Practice) publications reflect the views, at the time of publication, of: Shell International Oil Products B.V. (SIOP) and Shell International Exploration and Production B.V. (SIEP) and Shell International Chemicals B.V. (SIC) The Hague, The Netherlands, and other Service Companies. They
5、are based on the experience acquired during their involvement with the design, construction, operation and maintenance of processing units and facilities, and they are supplemented with the experience of Group Operating companies. Where appropriate they are based on, or reference is made to, nationa
6、l and international standards and codes of practice. The objective is to set the recommended standard for good design and engineering practice applied by Group companies operating an oil refinery, gas handling installation, chemical plant, oil and gas production facility, or any other such facility,
7、 and thereby to achieve maximum technical and economic benefit from standardization. The information set forth in these publications is provided to users for their consideration and decision to implement. This is of particular importance where DEPs may not cover every requirement or diversity of con
8、dition at each locality. The system of DEPs is expected to be sufficiently flexible to allow individual operating companies to adapt the information set forth in DEPs to their own environment and requirements. When Contractors or Manufacturers/Suppliers use DEPs they shall be solely responsible for
9、the quality of work and the attainment of the required design and engineering standards. In particular, for those requirements not specifically covered, the Principal will expect them to follow those design and engineering practices which will achieve the same level of integrity as reflected in the
10、DEPs. If in doubt, the Contractor or Manufacturer/Supplier shall, without detracting from his own responsibility, consult the Principal or its technical advisor. The right to use DEPs is granted by SIOP, SIEP or SIC, in most cases under Service Agreements primarily with companies of the Royal Dutch/
11、Shell Group and other companies receiving technical advice and services from SIOP, SIEP or SIC. Consequently, three categories of users of DEPs can be distinguished: 1)Operating companies having a Service Agreement with SIOP, SIEP, SIC or other Service Company. The use of DEPs by these Operating com
12、panies is subject in all respects to the terms and conditions of the relevant Service Agreement. 2)Other parties who are authorized to use DEPs subject to appropriate contractual arrangements. 3)Contractors/subcontractors and Manufacturers/Suppliers under a contract with users referred to under 1) o
13、r 2) which requires that tenders for projects, materials supplied or - generally - work performed on behalf of the said users comply with the relevant standards. Subject to any particular terms and conditions as may be set forth in specific agreements with users, SIOP, SIEP and SIC disclaim any liab
14、ility of whatsoever nature for any damage (including injury or death) suffered by any company or person whomsoever as a result of or in connection with the use, application or implementation of any DEP, combination of DEPs or any part thereof. The benefit of this disclaimer shall inure in all respec
15、ts to SIOP, SIEP, SIC and/or any company affiliated to these companies that may issue DEPs or require the use of DEPs. Without prejudice to any specific terms in respect of confidentiality under relevant contractual arrangements, DEPs shall not, without the prior written consent of SIOP and SIEP, be
16、 disclosed by users to any company or person whomsoever and the DEPs shall be used exclusively for the purpose for which they have been provided to the user. They shall be returned after use, including any copies which shall only be made by users with the express prior written consent of SIOP and SI
17、EP. The copyright of DEPs vests in SIOP and SIEP. Users shall arrange for DEPs to be held in safe custody and SIOP or SIEP may at any time require information satisfactory to them in order to ascertain how users implement this requirement. All administrative queries should be directed to the DEP Adm
18、inistrator in SIOP. NOTE: In addition to DEP publications there are Standard Specifications and Draft DEPs for Development (DDDs). DDDs generally introduce new procedures or techniques that will probably need updating as further experience develops during their use. The above requirements for distri
19、bution and use of DEPs are also applicable to Standard Specifications and DDDs. Standard Specifications and DDDs will gradually be replaced by DEPs. DEP 31.29.12.30-Gen.

21、hich is an upgrading and revision of Standard Specification P-5-3 dated March 1970, contains the minimum technical requirements for reciprocating positive displacement pumps and for metering pumps for use in oil refineries,chemical plants, gas plants and, where applicable, in exploration, production
22、 and new ventures. ThisspecificationgivesSIPM/SICMamendmentsandsupplementstothetwo corresponding API Standards: -APIStandard674,FirstEdition,May1980,PositiveDisplacementPumps- Reciprocating -API Standard 675, First Edition, March 1980, Positive Displacement Pumps - Controlled Volume It shall be used
23、 in conjunction with data/requisition sheet DEP 31.29.12.93-Gen. for reciprocating pumps. As a rule the requirements of this specification shall be adhered to. However, national and/or local regulations may exist in which some of the requirements are more stringent. The contractor shall determine by
24、 careful scrutiny which of the requirements are the more stringent and which combination of requirements will be acceptable as regards safety, economic and legal aspects. In all cases the contractor shall inform the principal of any deviation from the requirements of this specification which is cons
25、idered to be necessary, in order to comply with national and/or local regulations. The principal may then negotiate with the authorities concerned with the object of obtaining agreement to follow this specification as closely as possible. Unless otherwise authorized by SIPM, the distribution of this
26、 specification is confined to companies belonging to or managed by the Royal Dutch/Shell Group, and to contractors and manufacturers/suppliers nominated by them under cover of a secrecy agreement. All publications referred to are listed in Part IV. DEP 31.29.12.30-Gen. July 1983 Page 4 PART II GENER
27、AL INFORMATION This specification is written in four parts of which Part III, the principal part, gives SIPM/SICM amendments and supplements to API Std 674, First Edition, May 1980, and to API Std 675, First Edition, March 1980. Problems stemming from the publication of revisions or amendments to th
28、e above standards by the American Petroleum Institute in 1983 or subsequent years shall be referred to the principal. Reciprocating positive displacement pumps, direct-acting and power frame types, shall conform to API Std 674, as amended or supplemented by this specification. Metering pumps shall c
29、onform to API Std 675, as amended or supplemented by this specification, and to those amendments/supplements to API Std 674 indicated by the symbol (M) in the margin. For ease of reference, the clause (or paragraph) numbering of API Std 674 has been used throughout Part III of this specification. Wh
30、ere an amendment or supplement to a clause in API Std 674 applies equally to a corresponding clause in API Std 675, the instruction relative to the clause concerned in API Std 674 also identifies the corresponding clause in API Std 675. When there is no corresponding clause in API Std 675 to which r
31、eference can be made, when required, the symbol (M) in the left-hand margin indicates where metering pumps shall comply with the amendment/supplement concerned. Clauses (paragraphs) in API Std 674 and in API Std 675 not mentioned remain unaltered. Where cross references are made the number of the se
32、ction/sub-section/clause of this specification referred to is shown in brackets. A bullet () in the margin against certain clauses (paragraphs) in API Std 674 and API Std 675 indicates that a decision by the principal is required. These decisions shall be indicated directly in data/requisition sheet
33、 DEP 31.29.12.93-Gen., when provisions are made for them; otherwise, they shall be indicated in the data/requisition sheet(s) under the heading Additional Requirements, or stated in the purchase order. DEFINITIONS For the purpose of this specification, the following definitions shall hold: Shall and
34、 Should -the word shall is to be understood as mandatory, and the word should as strongly recommended to comply with the requirements of this specification. The Principal is the party which initiates the project and ultimately pays for its design and construction. The Principal will generally specif
35、y the technical requirements. The Principal may also include an agent or consultant, authorized to act for the Principal. *For Group operating companies having a service agreement with SIPM or SICM, the term Principal shall be taken as referring to SIPM - MFEE/21.
