3 TERMINOLOGY

3.1 Black Tube

Tube as manufactured without any subsequent surfacetreatment.

3.2 Nominal Bore

A size reference denoting the approximate bore of thetube. For each size of tube, the outside diameter is fixedby the corresponding screw thread dimensions ofIS 554 and therefore, the actual bore of each size oftube will vary according to the thickness.

3.3 Plain End

The end of the tubes shall be finished clean.

3.4 Bevel End

The finished tube end shall be with a specified angleand root face as given in Fig. 1.

3.5 Tube, Pipe

A long, hollow, open-ended object of circular or othercross-section. The term tube is synonymous with theterm pipe.

9 TOLERANCES ON THICKNESS AND MASS

9.1 The following manufacturing tolerances shall bepermitted on the tubes and sockets:

a) Thickness:

1) Welded tubes:Light tubes + not limited

– 8 percentMedium and heavy + not limitedtubes – 10 percent

2) Seamless tubes + not limited– 12.5 percent

b) Mass:

1) Single tube (light + 10 percentseries) – 8 percent

2) Single tube (medium ± 10 percentand heavy series)

3) For quantities per load + 7.5 percentof 10 tonnes, Min – 5 percent(light series)

4) For quantities per load ± 7.5 percentof 10 tonnes, Min(medium and heavyseries)

NOTE — For the purpose of minimum weighment of 10tonnes lot, the weighment may be done in convenient lotsat the option of the manufacturer.

10 JOINTS

10.1 All screwed tubes shall be supplied with pipethreads conforming to IS 554. Gauging in accordancewith IS 8999 shall be considered as an adequate testfor conformity of threads of IS 554.

10.1.1 Unless specified otherwise, tubes shall besupplied screwed with taper threads and fitted with onesocket having parallel thread. The socket shall conformto all requirements (except 6.4) of IS 1239 (Part 2).

10.1.1.1 In case of light tubes the application of taperpipe threads may be modified by permitting the outsidediameter of the tubes to be within the limits shown in col2 and 3 of Table 3. Where the tube approaches the lowerlimit of outside diameter, some incomplete threads(perfect at root and imperfect at the crest) may be expectedfrom and beyond the gauge plane. Such incompletethreads, shall not be regarded as justification for rejectionof the tubes. Also the minimum length of threads in lighttubes shall be 80 percent of that specified in IS 554.

10.2 The plain end pipes shall be supplied with squarecut. However, bevel end may also be supplied on mutualagreement between the purchaser and the manufacturer(see Fig. 1).

at the commencement and at the end of each workingperiod and at intervals not exceeding 2 h.

B-3.3 If on checking during production testing thereference standard defect is not detected even afterchanging the sensitivity by 2dB to allow for equipmentdrift, the equipment shall be recalibrated. Followingrecalibration, all tubes tested since the previous checkshall be retested, unless recordings from individuallyidentified tubes are available that permit classificationof those tubes into ‘suspect’ and ‘acceptable’ categories.

B-4 TEST PROCEDURE

Pass the tube to be inspected through the test unit atthe appropriate production speed, maintaining theproduction speed constant with ±10 percent underconditions identical to those used in the calibration ofthe equipment.

NOTE — Identical conditions include all instrument setting,mechanical motion, positioning of the encircling coil(s) inrelation to the tube and any other factor that affect thevalidity of the technique.

B-5 ACCEPTANCE

B-5.1 Any tube producing a signal lower than thesignals from the standard shall be deemed to havepassed this test.

B-5.2 Since NDT systems are known to be sensitive tosome features which do not cause leak, the tube rejectedby NDT may be retested hydraulically and whatevertubes pass the hydraulic test shall be accepted.

B-5.3 The tubes rejected in (see B-5.1) may also beretested off-line NDT equipment. Those which do notproduce reject level signals shall be accepted. Othersmay be accepted after cropping off the portionproducing reject level signals.

In this country, the regulations governing the use of tubes for conveying steam are laid down in the Indian BoilerRegulations published by the Central Boilers Board.

While formulating this standard, due consideration has been given to the trade practices followed in the countryin this field. Due consideration has also been given to international coordination among the standards prevailingin different countries. Assistance has been derived from the following publications:

ISO 65 : 1981 Carbon steel tubes suitable for screwing in accordance with ISO International Organizationfor Standardization

BS 1387 : 1985 Screwed and socketed steel tubes and tubulars and for plain end steel tubes suitable forwelding or for screwing to BS 21 : 1985 ‘Pipe threads for tubs and fitting where pressure-tightjoints are made on the threads’

This standard contains clauses 6.4, 7.1, 7.1.1, 11.2, 16.2 and 17.3 which call for an agreement between themanufacturer and the purchaser.

The other part of this standard is IS 1239 (Part 2) : 1992 ‘Specification for mild steel tubes, tubulars and otherwrought steel fittings: Part 2 Mild steel socket, tubulars and other wrought steel pipe fittings ( fourth revision )’.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the results of a test or analysis, shall be rounded off in accordance withIS 2 : 1960 ‘Rules for rounding off numerical values (revised )’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.

ERW Steel Pipes and Tubes

Based on the end user customer's requirement, ERW (electric resistance welded) steel pipes and tubes are available in various qualities, wall thicknesses, and diameters of the finished pipes. While manufacturing ERW steel pipes, only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel pipes and tubes possess high strength corrosion resistance, high deformability, high strength and high toughness. Before reaching the market place, ERW steel tubes and pipes are routed through numerous tests including a hydro-test, an ultrasonic weld inspection, bevel check, micrometer check, straightness evaluation, and ring gouge to ensure it’s quality. These pipes are used in fencing, line pipes, oil country tubulars, scaffolding, water and gas conveyance, structural, engineering purpose. There has been a tremendous increase in the production of ERW steel tubes due to growing demand in oil & gas industry, infrastructure and automobile usages.

Black Steel Pipes and Tubes

When steel pipe is forged, a black oxide scale forms on its surface to give it the finish which is seen on this type of pipe. Because steel is subject to rust and corrosion, the factory also coats it with protective oil. Those black steel are used for manufacturing pipe and tube, which will not rust for a long time and requires very little maintenance. It is sold in standard 21-foot lengths TBE. Black steel pipes and tubes are cut and threaded to fit the job. Fittings for this type of pipe are of black malleable (soft) cast iron. They connect by screwing onto the threaded pipe, after applying a small amount of pipe joint compound on the threads. Larger diameter pipe is welded rather than threaded. Black steel pipe is cut either with a heavy-duty tube cutter or cutoff saw or by hacksaw.

9 TOLERANCES ON THICKNESS AND MASS

9.1 The following manufacturing tolerances shall bepermitted on the tubes and sockets:

a) Thickness:

1) Welded tubes:Light tubes + not limited

– 8 percentMedium and heavy + not limitedtubes – 10 percent

2) Seamless tubes + not limited– 12.5 percent

b) Mass:

1) Single tube (light + 10 percentseries) – 8 percent

2) Single tube (medium ± 10 percentand heavy series)

3) For quantities per load + 7.5 percentof 10 tonnes, Min – 5 percent(light series)

4) For quantities per load ± 7.5 percentof 10 tonnes, Min(medium and heavyseries)

NOTE — For the purpose of minimum weighment of 10tonnes lot, the weighment may be done in convenient lotsat the option of the manufacturer.

10 JOINTS

10.1 All screwed tubes shall be supplied with pipethreads conforming to IS 554. Gauging in accordancewith IS 8999 shall be considered as an adequate testfor conformity of threads of IS 554.

10.1.1 Unless specified otherwise, tubes shall besupplied screwed with taper threads and fitted with onesocket having parallel thread. The socket shall conformto all requirements (except 6.4) of IS 1239 (Part 2).

10.1.1.1 In case of light tubes the application of taperpipe threads may be modified by permitting the outsidediameter of the tubes to be within the limits shown in col2 and 3 of Table 3. Where the tube approaches the lowerlimit of outside diameter, some incomplete threads(perfect at root and imperfect at the crest) may be expectedfrom and beyond the gauge plane. Such incompletethreads, shall not be regarded as justification for rejectionof the tubes. Also the minimum length of threads in lighttubes shall be 80 percent of that specified in IS 554.

10.2 The plain end pipes shall be supplied with squarecut. However, bevel end may also be supplied on mutualagreement between the purchaser and the manufacturer(see Fig. 1).

14.2 Bend Test on Tubes Up to and Including 50 mmNominal Bore

When tested in accordance with IS 2329 the tubes shallbe capable of withstanding the bend test withoutshowing any signs of fracture or failure. Welded tubesshall be bent with the weld at 90° to the plane of bending.The tubes shall not be filled for this test.

14.2.1 Ungalvanized tubes shall be capable of beingbent cold without cracking through 180° round a formerhaving a radius at the bottom of groove in the plane ofbending, equal to at least six times the outside diameterof the tube.

14.2.2 Galvanized tubes shall be capable of being bentcold, without cracking of the steel, through 90° rounda former having a radius at the bottom of the grooveequal to at least eight times the outside diameter of thetubes.

14.3 Flattening Test on Tubes Above 50 mm NominalBore

Rings not less than 40 mm in length cut from the endsof the selected tubes shall be flattened cold betweenparallel plates with the weld, if any at 90° (point ofmaximum bending) in accordance with IS 2328. Noopening shall occur by fracture in the weld area untilthe distance between the plates is less than 75 percentof the original outside diameter of the tube and nocracks or breaks in the metal elsewhere than in the weldshall occur until the distance between the plates is lessthan 60 percent of the original outside diameter.

NOTE — Slight premature cracking at the edges would notbe deemed to affect compliance with this standard.

at the commencement and at the end of each workingperiod and at intervals not exceeding 2 h.

B-3.3 If on checking during production testing thereference standard defect is not detected even afterchanging the sensitivity by 2dB to allow for equipmentdrift, the equipment shall be recalibrated. Followingrecalibration, all tubes tested since the previous checkshall be retested, unless recordings from individuallyidentified tubes are available that permit classificationof those tubes into ‘suspect’ and ‘acceptable’ categories.

B-4 TEST PROCEDURE

Pass the tube to be inspected through the test unit atthe appropriate production speed, maintaining theproduction speed constant with ±10 percent underconditions identical to those used in the calibration ofthe equipment.

NOTE — Identical conditions include all instrument setting,mechanical motion, positioning of the encircling coil(s) inrelation to the tube and any other factor that affect thevalidity of the technique.

B-5 ACCEPTANCE

B-5.1 Any tube producing a signal lower than thesignals from the standard shall be deemed to havepassed this test.

B-5.2 Since NDT systems are known to be sensitive tosome features which do not cause leak, the tube rejectedby NDT may be retested hydraulically and whatevertubes pass the hydraulic test shall be accepted.

B-5.3 The tubes rejected in (see B-5.1) may also beretested off-line NDT equipment. Those which do notproduce reject level signals shall be accepted. Othersmay be accepted after cropping off the portionproducing reject level signals.

In this country, the regulations governing the use of tubes for conveying steam are laid down in the Indian BoilerRegulations published by the Central Boilers Board.

While formulating this standard, due consideration has been given to the trade practices followed in the countryin this field. Due consideration has also been given to international coordination among the standards prevailingin different countries. Assistance has been derived from the following publications:

ISO 65 : 1981 Carbon steel tubes suitable for screwing in accordance with ISO International Organizationfor Standardization

BS 1387 : 1985 Screwed and socketed steel tubes and tubulars and for plain end steel tubes suitable forwelding or for screwing to BS 21 : 1985 ‘Pipe threads for tubs and fitting where pressure-tightjoints are made on the threads’

This standard contains clauses 6.4, 7.1, 7.1.1, 11.2, 16.2 and 17.3 which call for an agreement between themanufacturer and the purchaser.

The other part of this standard is IS 1239 (Part 2) : 1992 ‘Specification for mild steel tubes, tubulars and otherwrought steel fittings: Part 2 Mild steel socket, tubulars and other wrought steel pipe fittings ( fourth revision )’.

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the results of a test or analysis, shall be rounded off in accordance withIS 2 : 1960 ‘Rules for rounding off numerical values (revised )’. The number of significant places retained in therounded off value should be the same as that of the specified value in this standard.
