The w
5、ork of developing Inter- national Standards is carried out through IS0 technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental and non-governmental, in
6、 liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 1129 was developed by Technical Committe
7、e ISO/TC 5, Metal pipes and fittings, and was circulated to the member bodies in March 1979. It has been approved by the member bodies of the following countries : Australia Austria Belgium Canada Chile Czechoslovakia Denmark Finland France India Israel Italy Japan Korea, Rep. of Libyan Arab Jamahir

10、RD IS0 1129-1980 (El Steel tubes for boilers, superheaters and heat exchangers - Dimensions, tolerances and conventional masses per unit length 0 Introduction The outside diameters and thicknesses have been selected from IS0 4200. The masses per unit length are in accordance with clause 4. 1 Scope a
11、nd field of application This International Standard specifies the diameters, thicknesses, tolerances and conventional masses per unit length of fired tubes, including superheater and heat exchanger tubes. This International Standard does not apply for tubes according to IS0 6756 and IS0 6759. NOTE -
12、 This International Standard may not cover all types of heat exchangers. 2 References IS0 4200, Plain end steel tubes, welded and seamless - General tables of dimensions and conventional masses per unit length. ) IS0 5252, Steel tubes - Tolerance systems.

13、gers.” IS0 6759, Seamless tubes for heat exchangers. ) 3 Tolerances The tolerances permitted on the outside diameter and thickness of the tubes result from the method of manufacture, the steel type and the heat treatment. The tolerances should be selected from the following values : 3.1 Tolerances o
14、n outside diameter D, : f 1 % with a minimum of f 050 mm D, : f 0,75 % with a minimum of + 030 mm D, : +_ 0,50 % with a minimum of +_ 0,lO mm The tolerances on outside diameter include ovality. 3.2 Tolerances on thickness T 2 : & 12,5 % with a minimum of k 0,4 mm T, : f 10 % with a minimum of f 0,2
15、mm T, : f 7,5 % with a minimum of f 0,15 mm T, : f 5 % with a minimum of f 0,lO mm The tolerances on thickness include eccentricity. 3.3 Other tolerances For tolerances, other than outside diameter and thickness, reference shall be made to IS0 5252. 4 Conventional masses per unit length The conventi
16、onal masses per unit length given in table 1 for carbon and alloy steel tubes have been selected from IS0 4200. The conventional masses per unit length given in table 2 for austenitic stainless steel tubes are the masses of IS0 4200 multiplied by a factor of 1 ,015. This factor assumes an average de
17、nsity for these tubes of 7,97 kg/dm3. The conventional masses per unit length given in table 3 for ferritic and martensitic stainless steel tubes are the masses of IS0 4200 multiplied by a factor of 0,965. This factor assumes an average density for these tubes of 7,73 kg/dm3. I) At present at the st
