Indian StandardSPECIFICATION FOR

STEEL PIPE FLANGES

o. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institutionon 29 October 1971, after the draft finalized by the Steel Tubes, Pipes andFittings Sectional Committee had been approved by the Structural andMetals Division Council.

0.2 The importance of piping installations in various industries h~necessitated the preparation of this standard for the users and manufac­turen of flanges and flanged fi ttings,

0.1 In the formulation of this standard due weightage has been given tointernational co-ordination among the standards prevailing in differentcountries in addition to relating it to the practice in the field in thiscountry. Considerable assistance has been drawn from BS 4504: 1969• Flanges and bolting for pipes, valves and fittings' issued by the BritishStandards Institution.

0.4 For the information of designers the high temperature properties ofsteels, wherever available, have been given in Appendix A. Values forother steels will be included when available.

0.5 This standard contains clauses 1.3, 5.2 and 7.1 which call for anagreement between the purchaser and the manufacturer.

0.6 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, express­ing the result of a test or analysis, shall be rounded off in accordance withIS : 2·1960·. The number of significant places retained in the rounded offvalue should be the same as that of the specified value in this standard.

I. SCOPE1.1 This standard covers the requirements for cast, forged and plate orflat steel pipe flanges of the following types for use in industry for oil,water, steam, air, gas and chemical services:

a) Integral,b) Weldin~ neck,

c) Plate,d) Screwed boss,e) Slip-on boss,f) Loose ftanges for welded-on lapped pipe ends, andg) Blank.

1.2 This standard does not specify limitations on the use of various methodsof attachment of flanges to pipe or other equipment. The adequacy foroperating conditions of any method of attachment specified should bedetermined by the designer of the piping or equipment.

1.3 The types and materials of gaskets used shall be agreed between thepurchaser and the manufacturer.

NOTa 1- The term • plate 8an.' indicatel the .hape or the ftanse u the &an.. areDot necell&rily made from .teel plate but may be made from rOI"l~ or cast Iteel.

a) Size,b) Materials specification,c) Class rating, andd) Manufacturer's name or trade-mark.The remaining information should be made available to the purchaser,

if required.11.2 The product may also be marked with Standard mark.

11.2.1 The use of tbe Standard Mark is governed by tbe provisions of tbeBureau of Indian Standards Act, 1986 and tbe Rules and Regulations madethereunder, The details of conditions under wbich tbe licence for the use ofStandard Mark may be granted to manufacturers or producers may be obtainedfrom the Bureau of Indian Standards.

12. PRESERVATION AND PACKING

12.1 After inspection, and before despatch, flanges shall, if necessary, bedried and cleaned.

12.1.1 Threaded and machined surfaces shall be well-covered with anapproved rust preventive material that will not become fluid and run offat 65°0.

12.1.2 Exposed faces of flanges shall be protected over their entiresurface with a suitable close-fitting protector securely attached at notless than four points. The type of protector and method of attachmentshall be approved by the purchaser.

12.2 PackiDI12.2.1 Flanges shall be bundled by bolting them together or securing
