Steel Tube Handbook - 2018

47 Tube tolerances – see page 47 - table 10 and 11. For tubes are valid minimal wall thickness - so the tolerances of T are only plus. The deliveries of hot finished tubes to these tolerances only upon agreement. Hot finished tubes are usually delivered with average wall thickness (two sided tolerances of T). Method of manufacture and delivery conditions – hot finished or cold drawn – depend on tube dimension or upon agreement (See table 5, page 40-41) Outside diameter Hot finished to 4” (101,6 mm) over 4”–7 1 / 2 ” (101,6–190,5 mm) –1/32 (0,8 mm) –3/64 (1,2 mm) +1/64 (0,4 mm) +1/64 (0,4 mm) Cold finished to 1” (25,4 mm) over 1”–1 1 / 2 ” (25,4–38,1 mm) over 1 1 / 2 ”–2” (38,1–50,8 mm) over 2”–2 1 / 2 ” (50,8–63,5 mm) over 2 1 / 2 ”–3” (63,5–76,2 mm) over 3”–4” (76,2–101,6 mm) over 4”–7 1 / 2 ” (101,6–190,5 mm) –0.004 (0,1 mm) –0.006 (0,15 mm) –0.008 (0,2 mm) –0.010 (0,25 mm) –0.012 (0,3 mm) –0.015 (0,38 mm) –0.015 (0,38 mm) +0.004 (0,1 mm) +0.006 (0,15 mm) +0.008 (0,2 mm) +0.010 (0,25 mm) +0.012 (0,3 mm) +0.015 (0,38 mm) +0.025 (0,64 mm) Allowed outside diameter tolerances according to ASTM A450/A450M, ASTM A1016/A1016M (ASME SA) Table 10 Ovality for thin-wall tubes [T ≤ 0,020in (0,5mm) / T ≤ 2% D up to D=2in (50,8mm) / T ≤ 3% D for D over 2in]: Tubes with D ≤ 1in (25,4mm) = 0,020in (0,5mm), tubes with D>1in = up to 2% of D (difference of maximum values) Allowedwall thickness tolerances according to ASTMA450/A450M, ASTMA1016/A1016M (ASME SA) Table 11 Wall thickness Hot finished to 0,095“ (2,4 mm) 0 +40 % over 0,095“ - 0,15“ (2,4 - 3,8 mm) 0 +35 % 0,15“ - 0,18“ (3,8 - 4,6 mm) 0 +33 % over 0,18“ (4,6 mm) 0 +28 % Cold finished With outside diameter to 1 1/2“ (38,1 mm) 0 +20% over 1 1/2“ (38,1 mm) 0 +22% For tubes with D≥2in and T≥0,220in are permitted divergences from calculated average T ±10%.
