Steel Tubes, Pipes and Fittings Sectional Committee, MTD 19

FOREWORDThis Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards, after thedraft finalized by the Steel Tubes, Pipes and Fittings Sectional Committee had been approved bythe Metallurgical Engineering Division Council .

This standard was originally published in 1966, first revised in 1981 and subsequently in 1991.While reviewing this standard in the light of the experience gained during these years, thecommittee felt to revise the same, taking note of the present practices being followed in thecountry and also overseas standards existing on the subject. I n the revision of this standard thefollowing main modifications have been made:

a) Provision of outside diameters and thicknesses of pipes have been revised in accordance withthe provisions, of International Standards.

b) Exhaustive tables for chemical composition of steels to be used and tensile properties of the

pipes have been incorporated.c)Annexes A to D as the guideline for Protection Against Corrosion have been added which

recommend methods of protecting pipes against corrosion. It covers external as well asinternal protection. Separate Indian Standards incorporating various types of protectivecoatings and materials thereof are expected to be published in due course of time.

In the formulation of this standard due weightage has been given to international coordinationamong the standards prevailing in different countries in addition to the practices in the country.This has been met by deriving assistance from the following publications:

This edition 4.2 incorporates Amendment No. 1 (May 2002) and Amendment No. 2 (October 2003).Side bar indicates modification of the text as the result of incorporation of the amendments.

For the purpose of deciding whether a particular requirement of this standard is complied with,the final value, observed or calculated, expressing the result of a test or analysis, shall be roundedoff in accordance with I S 2 : 1960 Rules for rounding off numerical values ( r evi sed). The numberof significant places retained in the rounded off value should be the same as that of the specifiedvalue in this standard.

9.3Guided Bend Test (For SAW Pipes)

Strips not less than 40 mm wide, cutcircumferentially from pipes perpendicular toweld seam with the weld near the middle of thesample shall, without fracture, be doubled overa round bar the diameter of which shall becalculated as given below. The weldreinforcement shall be removed from the faces.

located in the parent metal, the heat affected

zone, or the fusion line, shall not be the causefor rejection.

Any test specimen that shows defectivepreparation, or material imperfection unrelatedto the intent of the particular mechanical test

whether observed before or after testing, maybe discarded and replaced by another specimenfrom the same length of the pipe.

9.3.3 On examination of the bent specimen,opening out of a slight defect due to incompleteroot penetration or lack of root fusion need notbe considered a cause for rejection provided thedefect has sound metal at the back and oneither side of it. In border l ine cases, furthertests shall be made on specimens from thesame weld adjacent to the original testspecimen.

ANNEX D

( Foreword andCl ause16.1 )

TAPE COATING SYSTEM

D-1 GENERALFor corrosion protection of metal pipes oftenseveral outer wraps, hot or cold applied areused. For very corrosive soil condition coldapplied tapes are used on steel pipes at site. Inthe factory normally hot applied tape coatingare used. Unless the transportation is madevery carefully these factory applied tapecoating may get damaged.

For normal construction considerations coldapplied tapes are applied as a three layersystem consisting:

a) Primer,

b) Corrosion preventive tape (inner layer),and

c) Mechanical protective tape (outer layer).

D-2 OUTER LAYER TAPE

The outer layer shall consist of polyolefinbacking with a laminated elastomer typeadhesive. The outer layer tape shall becompatible with the inner layer tape. Thefunction of the outer layer tape shall beprimarily to provide mechanical and outdoorweathering protection to the tape system andsecondarily, to contribute to the overall

corrosion protection properties of the system.

D-3 PRIMER

The primer shall be applied to the properlyprepared pipe surface before application of theinner layer tape. The fusion bonding mediumbetween the pipe surface and inner layer tape.

D-4 INNER LAYER TAPEThe inner layer tape shall consist of a polyolefinbacking with a lamented adhesive. The innerlayer tape shall be applied after the primer andbefore the outer layer tape.

The primary purpose of the inner layer tape isto provide the corrosion protection coating.

D-5 TOTAL COATING SYSTEM

The total thickness of the system made up ofinner tape and outer tape may vary dependingon pipe diameter operating condition andinstallation conditions. In no case shall the

thickness be less than those given below:The tapes can be applied directly onto theprimed pipe surface by means of mechanicalcoating/wrapping equipment manually or bymachine. The inner layer tape shall be speciallyapplied with overlap width and applicationtensions as recommended by themanufacturers. The minimum overlap shall benot less than 25 mm when a new roll of tape isstarted and the ends shall be overlapped atleast 150 mm measured circumferentially. Theoverlap shall be smooth and shall be located toensure the continuity of the inner layer coating.

The outer layer tape shall be applied over theinner layer tape using the same technique.

The overlap of the outer layer shall not coincidewith the overlap of the inner layer tape. Theminimum overlap of the applied tape andminimum end tap of two rolls shall be same asspecified for inner tape.
