Tolerances for diameter and out of roundness

API 5L pipe wall thickness tolerance

Wall thickness t mm (in)	Tolerances a mm (in)
SMLS pipe b
≤4,0 (0.157)	+0,6 (0.024) -0,5 (0.020)
＞4,0 (0.157) to ＜25,0 (0.984)	+0,150 t -0,125 t
≥25,0 (0.984)	+3,7 (0.146) or 0,1 t, whichever is the greater -3,0 (0.120) or . 0,1 t, whichever is the greater
Welded pipe c,d
≤ 5,0 (0.197)	± 0,5 (0.020)
＞5,0 (0.197) to ＜15,0 (0.591)	± 0,1 t
≥ 15,0 (0.591)	± 1,5 (0.060)

Please Note:

a If the purchase order specifies a minus tolerance for wall thickness smaller than the applicable value given in this table, the plus tolerance for wall thickness shall be increased by an amount sufficient to maintain the applicable tolerance range.
b For pipe with D W 355,6 mm (14.000 in) and t W 25,0 mm (0.984 in), the wall-thickness tolerance locally may exceed the plus tolerance for wall thickness by an additional 0,05 t, provided that the plus tolerance for mass (see 9.14) is not exceeded.
c The plus tolerance for wall thickness does not apply to the weld area.
d See 9.13.2 for additional restrictions.

API 5L pipe length tolerances shall be complied as following conditions:
a. Random length shall be delivered as below table 12.
b. Approximate lengths shall be delivered as tolerances of +/- 500 mm.
