t = Nominal Wall Thickness D = Ordered Outside Diameter Outside Diameter: Based on circumferential measurement. Out-of-Roundness / Ovality: Difference between major and minor outsidediameters. Alignment / Straightness: Using a 3 m straightedge placed so that both ends are in contact with the pipe, measure the contact deviation between the pipe and the straightedge.
(a) Le tolleranze del diametro esterno comprendono l’ovalizzazione, fatta eccezione per tubi sottili (tubi avente uno spessore del 3 % o meno del diametro esterno specificato) per i quali la tolleranza del diametro è applicabile solo alla media degli estremi valori del diametro (massimo e minimo), in una qualsiasi sezione trasversale. Per i tubi sottili, la differenza nelle letture esterne estreme (ovalizzazione) di una qualsiasi sezione trasversale non deve superare l’1,5 % del diametro esterno specificato.
b) For seamless pipe only. Tolerances on welded pipe shall be as agreed between the manufacturer and the purchaser.
(c) For thin-wall pipe, defined as pipe having a wall thickness of 3 % or less of the specified outside diameter, the diameter tolerance, shall apply only to the mean of the extreme (maximum and minimum) outside diameter readings in any one cross section. For thin-wall pipe, the difference in extreme outside readings (called ovality) in any section shall not exceed twice the permissible variations in outside diameter of the specified diameter.
d) Normal Wall Tube and As-Drawn, ovality will be held within the outside diameter tolerances shown in the table. Normal Wall Tube and Annealed, ovality will be held within 2 % of the theoretical average outside diameter. Light-Wall Tube and As-Drawn, up to but not including 1 1⁄4 in. (31.8 mm) in outside diameter, ovality will be held within 2 % of the theoretical average outside diameter. Light-Wall Tube and Annealed, Ovality will be held within 3 % of the theoretical average outside diameter.
(e) The permissible variations in this table apply to individual measurements, including out-of-roundness (ovality) except for the following:
(f) For pipe 5 in. (127 mm) and under in outside diameter, the tolerance on the outside diameter applies for individual measurements and includes ovality. For pipe over 5 in. (125 mm) in outside diameter, the mean outside diameter shall conform to the permissible variations of this table and individual measurements shall not exceed twice the permissible variations of this table.
(g) Non c’è tolleranza supplementare per l’ovalizzazione su tubi con uno spessore nominale maggiore del 3 % del diametro esterno. Su questi tubi, la media della misurazione massima e minima del diametro esterno dovrà essere all’interno della tolleranza del diametro esterno. Una tolleranza supplementare di ovalizzazione, pari al doppio della tolleranza del diametro, applicata +/-1/2, è consentita per tubi con uno spessore nominale del 3% o inferiore del diametro esterno nominale.
(h) Light-Wall Tube, the plus and minus wall tolerance shown in the table shall apply down to and including 0.005 in. (0.13 mm) in wall thickness. For wall thicknesses less than 0.005 in. (0.13 mm), the tolerance shall be +/-0.0005 in. (0.013 mm).
(p) If specific cut lengths are ordered. (q) Random Lengths: Where nominal random lengths on tubing 1⁄8 in. (3.2 mm) and larger in outside diameter are specified, a length tolerance of +/- 31⁄2 ft (1.06 m) applies to the nominal length.This is a total spread of 7 ft (2.10 m). Random lengths in sizes 1⁄8 in. (3.2 mm) and larger in outside diameter shall be subject to a length range of 5 to 24 ft (1.50 to 7.30 m). Long random lengths are subject to a range of 15 to 22 ft (4.57 to 6.70 m). Random lengths in sizes up to, but not including 1⁄8 in. (3.2 mm) in outside diameter, and fragile light-wall tubes over this outside diameter are subject to the length range of 1 to 15 ft (0.30 to 4.57 m). (r) Up to 2” (50.8mm)
(r) Fino a 2 ” (50,8 mm)
(s) Queste variazioni ammissibili di lunghezza si applicano a pipe o tubes in verghe. Esse si applicano lunghezze fino a 24 ft (7,3 m) . Per lunghezze superiori a 24 m, un’ulteriore tolleranza di 1/8”(3,2 mm) per ogni 10 ft (3,0 m) o della stessa frazione, è ammessa fino ad un massimo di ½” (12,7 mm).
Round tubing is subject to a straightness tolerance of one part in 600 [equivalent to a depth of arc of 0.030 in. (0.76 mm) in any 3 ft (0.91 m) of length].
(u) For more detailed information please see the relevant ASTM/ASME code.

a) Options that have to be specified.
b) T<=0.01D and T<=4mm
c) T<=0.05D
d) For 219,1<D<=610 & 0,05D<T<=0,09D
e) For 30<=D<=219,1 or 219,1<D0,09D
0) The out-of-roundness (0) shall be calculated using the following equation:
(Dmax-Dmin)/Dx100
where
0 = out-of-roundness, in percentage;
Dmax = max outside diameter D, measured in the same plane, in mm;
Dmin = min outside diameter D, measured in the same plane, in mm;
D = specified outside diameter, in mm.
Other types of bevels can be made on request.
