FOREWORD

This Indian Standard ( Second Revision ) was adopted by the Bureau of Indian Standards, after the draftfinalized by the Pig Iron and Cast Iron Sectional Committee had been approved by the Metallurgical EngineeringDivision Council.

This standard was first published in 1964 and subsequently revised in 1979, .

For long it was believed that the fittings and accessories suitable for centrifugally cast ( spun ) iron spigot andsocket soil waste and ventilating pipes should be thinner than the fittings and accessories suitable for sand cast

;“4

spigot and socket soil waste ventilating pipes.,’

As such a single specification covering both the types of pipes and fittings, presently covered in IS 1230:1979‘Cast iron rainwater pipes and pipe fittings ( second revision )’. IS 1729:1979 ‘Sand cast iron spigot and socketsoil, waste and ventilating pipes, fittings and accessories (first revision )‘ would serve the purpose better and

IRON/DUCTILE IRON DRAINAGE PIPES ANDTTINGS FOR OVER GROUND NON-PRESSURE

PIPELINE SOCKET AND SPIGOT SEI?IES y(Second Revision )

1 SCOPE

1.1 This standard covers the requirements of castiron or ductile iron non-pressure above ground pipesand fittings used for discharge of waste water, sewage,rain water and for ventilation.

1.2 The pipes may be manufactured by centrifugallycast ( spun ) process in metal moulds or sand castand fittings by sand cast process.

1.3 This standard is applicable to cast iron or ductileiron pipes and fittings with either Type A or T~e Bsockets and having spigots as specified in thisstandard, Double socketted pipe lengths and weighthave also been included and these should comply withthe requirements of sockets and barrel pipe sectionspecified in the standard. In case of other type ofsocket/spigot joint the design should be based onthe dimensions of the spigots given in the standard,for reasons of safety and interchangeability.

3 DEFINITIONS

3.1 The distinctive character of discharge pipelineis that products flow through them in a single directionunder the force of gravity they are thus laid on a singleslope in the direction of flow. As a result, they includedescending, vertical, oblique or slightly slopingcomponents, but excluding any horizontal or ascendingcomponents.

3.2 For the purpose of this standard the followingdefinitions shall apply.

3.2.1 Above Ground — Pipeline within or external toa building including basements but excluding pipelinewhich has entered the ground ( see Fig. lC ).

3.2.2 Right Hand Fittings — A bend or breach soconstructed that when it is viewed with the accessdoor facing the observer, the arm of the bend or branchprojects to the right in the ascending direction(see Fig. la).

3.2.3 Left Hand Fittings — A bend or branch soconstructed that when it is viewed with the accessdoor facing the observer, the arm of bend or branchprojects to the left in the ascending direction(see Fig. lb).

requirements specified in the Tables 1 to33.

5.3 The pipes and fittings shall be stripped with allprecautions necessary to avoid warping or shrinkingdefects. The pipes and fittings shall be free from defectsother than any unavoidable surface imperfectionswhich may result from the method of manufacture andwhich do not affect the use ofthe fittings. By agreementbetween the purchaser and the manufacturer minordefects may be rectified.

5.4 The pipes and fittings shall be capable of beingcut with the tools normally used for installation. Thehardness of the external unmachined surface of thepipe and fittings should not exceed 215 HB whentested in accordance with IS 1500.

5.4.1 In case the hardness is more than 215 HB,fracture test shall be carried out and if fracture is grey(without showing any chilling effect ) such pipes andfittings shall be accepted.

5.5 Alternatively the Brinell hardness test shall becarried out on the test bar, cast from the same metaland of thickness not exceeding 10 mm.

IS 1729:2002

in Table 1.

10.2 The tolerance on mass shall be –5 percent.

10.3 No limit lo the plus tolerances of wall thicknesshave been specified.

11.2 Coating shall not be applied to any pipe or fittingunless its surfaces are clean, dry and free from rust.

11.3 Unless otherwise agreed between the purchaserand the manufacturer all pipes and fittings shall besupplied coated externally and internally with the samematerial by dipping in a tar or suitable base bath. Thepipes may be either preheated before dipping or thebathrnaybe uniformly heated. Alternatively, ifmutuallyagreed between the purchaser and the manufacturer,the pipes and fittings may be coated by spraying orbrush painting.

11.4 The coating material shall set rapidly with goodadherence and shall not scale off.

11.5 Where the coating material has a tar or similarbase, it shall be smooth and tenacious and hard enoughnot to flow when exposed to a temperature of 65°Cbut not so brittle at a temperature of O°C as to chipoffwhen scribed lightly with a penknife, The retentionperiod of sample at above temperature shall be up to5 min.

11.6 The coating test shall be conducted on a samplesize not less than 10 cm2 in area cut from a pipe orfitting.

11.7 Pipes or fittings which are imperfectly coatedor where the coating does not set or conform to therequired quality, specified in 11.1 to 11.7, the coatingshall be removed and the pipe or fitting be re-coated.

12 MARKING

12.1 Each pipe and fitting shall have cast, stampedor indelibly painted on it by the following:

a) Mantiacturer’s name, initials or identilcationmark,

3

-J

IS 1729:2002

b) The nominal diameteL

c) The last two digits of the year of manufhcturm,and

d) Any other mark required by the purchaser.

12.2 BIS Certification Marking

The pip> and fitting may also be marked with theStandard Mark.

12.2.1 The use of the Standard Mark is governed bythe provisions of the Bureau ofIndian Standards Act1986, and the Rules and Regulations made thereunder.The details of conditions under which the Iicence foruse of the Standard Mark may be granted tomanufacturers of producers maybe obtained from theBureau of Indian Standards.
