1、TECHNICAL SPECIFICATION THERMAL INSULATION (AMENDMENTS/SUPPLEMENTS TO THE CINI MANUAL “INSULATION FOR INDUSTRIES“) DEP 30.46.00.31-Gen. July 1999 DESIGN AND ENGINEERING PRACTICE This document is confidential. Neither the whole nor any part of this document may be disclosed to any third party without
2、 the prior written consent of Shell International Oil Products B.V. and Shell International Exploration and Production B.V., The Hague, The Netherlands. The copyright of this document is vested in these companies. All rights reserved. Neither the whole nor any part of this document may be reproduced
3、, 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 owners. PREFACE DEP (Design and Engineering Practice) publications reflect the views, at the time of publicati
4、on, 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 are based on the experience acquired during their involvement with the design
5、, 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, national and international standards and codes of practice. The objective is to set
6、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, and thereby to achieve maximum technical and economic benefit from standardi
7、zation. 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 condition at each locality. The system of DEPs is expected to be sufficiently fl
8、exible 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 the quality of work and the attainment of the required design and engineering
9、 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 DEPs. If in doubt, the Contractor or Manufacturer/Supplier shall, without det
10、racting 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/Shell Group and other companies receiving technical advice and services from
11、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 companies is subject in all respects to the terms and conditions of the relevant
12、 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) or 2) which requires that tenders for projects, materials supplied or - genera
13、lly - 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 liability of whatsoever nature for any damage (including injury or death) suffere
14、d 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 respects to SIOP, SIEP, SIC and/or any company affiliated to these companies that m
15、ay 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 disclosed by users to any company or person whomsoever and the DEPs shall be
16、 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 SIEP. The copyright of DEPs vests in SIOP and SIEP. Users shall arrange for DEP
17、s 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 Administrator in SIOP. NOTE: In addition to DEP publications there are Standard
18、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 distribution and use of DEPs are also applicable to Standard Specifications and DDD
19、s. Standard Specifications and DDDs will gradually be replaced by DEPs. DEP 30.46.00.31-Gen.

July 1999 Page 4 PART IINTRODUCTION 1.1SCOPE This DEP specifies requirements and gives recommendations for external thermal insulation of above ground surfaces of equipment and piping. This DEP is based on th
31、e *CINI Manual “Insulation for Industries“ (English Version), dated 1997-11-03. Note: * CINI = Committee Insulation Netherlands Industry This DEP replaces the DEP of the same number dated December 1988. This revision also incorporates the relevant contents of DEP 30.46.00.32-Gen. dated October 1988
32、and that DEP is now withdrawn. This DEP is divided into six parts: Part I gives an introduction, outlines the relationship between this DEP and the CINI Manual and explains the other parts. The CINI Manual covers both hot and cold insulation for indoor and outdoor facilities, but not all parts of th
33、e CINI Manual are applicable to thermal insulation practices within the Shell Group. However, the applicable material specifications and the numerous construction details, obtained from different disciplines and years of experience, form a good basis for a proper insulation standard. Part II contain
34、s standard practices and procedures not covered by the CINI Manual. Part III gives amendments and supplements to the CINI Manual. For ease of reference, the clause numbering of the CINI Manual has been used. Clauses of the CINI Manual that are not mentioned shall apply as written. Wherever reference
35、 is made to the CINI Manual it shall be understood to mean the CINI Manual as amended/supplemented by this DEP. PartIVspecifiesrequirementsandgives recommendationsforinspection and maintenance of existing insulation systems which are not covered in the CINI Manual. Part V lists the publications refe
36、renced in this DEP. Appendices, containing diagrams and drawings. 1.2DISTRIBUTION, INTENDED USE AND REGULATORY CONSIDERATIONS Unless otherwise authorised by SIOP and SIEP, the distribution of this DEP is confined to companies forming part of the Royal Dutch/Shell Group or managed by a Group company,
37、 and to Contractors nominated by them (i.e. the distribution code is “C“, as described in DEP 00.00.05.05-Gen.). This DEP is intended for use in oil refineries, chemical plants, gas plants, onshore and offshore oil and gas production facilities, loading and unloading terminals, and supply/ marketing
38、 installations. If national and/or local regulations exist in which some of the requirements may be more stringent than in this DEP the Contractor shall determine by careful scrutiny which of the requirements are the more stringent and which combination of requirements will be acceptable as regards
39、safety, environmental, economic and legal aspects. In all cases the Contractor shall inform the Principal of any deviation from the requirements of this DEP which is considered to be necessary in order to comply with national and/or local regulations. The Principal may then negotiate with the Author
40、ities concerned with the object of obtaining agreement to follow this DEP as closely as possible. 1.3DEFINITIONS For the purpose of this DEP the following definitions shall apply: The Principal is the party that initiates the project and ultimately pays for its design and construction. The Principal
41、 will generally specify the technical requirements. The Principal may also include an agent or consultant, authorised to act for the Principal. DEP 30.46.00.31-Gen. July 1999 Page 5 The Main Contractor is the party that carries out all or part of the design, engineering, procurement, installation an
42、d commissioning or management of a project. The Principal may sometimes undertake all or part of the duties of the Main Contractor. The Insulation Contractor is the party that carries out the insulation works, including engineering, material supply, installation and quality control. The Manufacturer
43、/Supplier/Vendor is the party that manufactures or supplies materials, equipment and services to perform the duties specified by the Main Contractor and/or Insulation Contractor. The word shall indicates a requirement. The word should indicates a recommendation. DEP 30.46.00.31-Gen. July 1999 Page 6
44、 PART II INSULATION SCOPE, ENGINEERING, APPLICATIONAND QUALITY CONTROL 1.DESIGN OF THERMAL INSULATION SYSTEMS DEP 30.46.00.31-Gen. July 1999 Page 7 1.1EXTENT OF THERMAL INSULATION Thermal insulation is required for: -Thermal conservation of equipment and piping if economically justified. -Temperatur
45、e control of processes or products, e.g. to avoid condensation, solidification, or too high a viscosity. -Personnel protection, i.e. on surfaces with a temperature of 70 C or higher if these present a danger. -Preventing or reducing damage to equipment and piping from exposure to freezing conditions
46、. In the engineering stage attention shall be paid to the insulation design, bearing in mind optimal life cycle costs, process requirements, maintenance aspects of insulated lines during operation and possible corrosion under insulation. Insulation shall not be applied to piping or equipment that ha
47、s been designed to emit heat or where cooling is required or acceptable by the process (e.g. piping to air coolers, blow down systems and condensate return lines) if there is no heat recovery at the end of the line. Each line should be insulated separately; a common insulation cover should not enclo
48、se adjacent lines. If approved by the Principal, deviations shall be shown on the piping drawings. Valves, flanges and nozzles shall be insulated, unless other requirements are overruling, e.g.: -Flanges in hydrogen service shall not be insulated. -Flanges in systems containing hydrocarbons above th
49、eir auto-ignition temperature shall not be insulated. -The 80% rule for bolting has been applied to flanges in accordance with ASME B31.3 (ref. DEP 31.38.01.11-Gen.). Valves and flanges in piping shall be provided with removable insulation covers. Nameplates and stampings shall be left clear of insulation or shall be fitted on the outside of the cladding. All metal surfaces under insulation shall be suitably protected with a complete paint system in accordance with DEP 30.48.00.31-Gen. or DEP 70.48.10.10-Gen. DEP 30.46.00.31-Gen.
