Permitted Variations in Wall Thickness
In addition to the implicit limitation of wall thickness
for seamless pipe imposed by the limitation on weight in
Specification A999/A999M, the wall thickness for seamless
and welded pipe at any point shall be within the tolerances
specified in Table 3, except that for welded pipe the weld area
shall not be limited by the “Over” tolerance. The wall thickness
and outside diameter for inspection for compliance with this
requirement for pipe ordered by NPS and schedule number is
shown in Table X1.1.

Mechanical Tests, Grain Size Determinations, and
Weld Decay Tests Required

1 Mechanical Testing Lot Definition—The term lot for
mechanical tests shall be as follows:
1.1 Where the final heat treated condition is obtained,
consistent with the requirements of 6.2, in a continuous
furnace, by quenching after hot forming or in a batch-type
furnace equipped with recording pyrometers and automatically
controlled within a 50 °F [30 °C] or lesser range, the term lot
for mechanical tests shall apply to all pipes of the same
specified outside diameter and specified wall thickness (or
schedule) that are produced from the same heat of steel and
subjected to the same finishing treatment within the same
operating period.
1.2 Where the final heat treated condition is obtained,
consistent with the requirements of 6.2, in a batch-type furnace
not equipped with recording pyrometers and automatically
controlled within a 50 °F [30 °C] or lesser range, the term lot
shall apply to the larger of: (a) each 200 ft [60 m] or fraction
thereof and (b) those pipes heat treated in the same furnace
batch charge for pipes of the same specified outside diameter
and specified wall thickness (or schedule) that are produced
from the same heat of steel and are subjected to the same
finishing temperature within the same operating period.
