SUPPLEMENTARY REQUIREMENTS S1. U-Bent Tubes

The following supplementary requirements shall apply when U-bent tubes are specified by the purchaser in the inquiry,
contract, or order. S1.1 Limitation of Supplementary Requirements for U-bent Tubes S1.1.1 The requrements for U-bent tubes
included in this supplement are limited to the alloys, conditions (tempers), tube outside diameter (OD), and wall thickness
ranges and bend radii listed in Table 6.

S1.2 Permissible Variations in Dimensions (Fig. S1) S1.2.1 Leg Spacing - The leg spacing, measured between the points
of tangency of the bend to the legs shall not vary from the value (2R - specified tube OD) by more than the amounts shown
below where R is the specified centerline bend radius:

Centerline Bend Radius (R), in. (mm)	Tolerance, in.(mm)
Up to 18 (457), incl	1/16(1.6)
Over18 to 30 (457 to 762), incl	3/32(2.4)
Over 30 to 36(762 to 914), incl	1/8(3.2)

S1.2.2 Diameter of Tube in U-Bent Section - Neither the major, nor the minor outside diameter of the tube at any one
cross section included within the points of tangency of the bend shall deviate from the nominal diameter prior to bending
by more than 10%. S1.2.3 Wall Thickness of Tube in U-Bent Section -The wall thickness of the apex of the U-bent section
shall be not less than the value determined by the following equation: Tf=T(2R)/(2R + D) where

Tf = thickness after bending, in.(mm)
T = minimum permissible thickness of tube wall prior to bending, in.(mm)
R = centerline bend radius, in. (mm),
and D = nominal outside diameter of the tube, in. (mm).

When specified by the purchaser, proof of conformance to this requirement shall be obtained by bending a tube specimen,
representative of the material offered, to the scheduled radiusof bend, cutting the tube at the apex of the bend, measuring
the tube wall at the cross section of this apex section, and comparing the measured value with the calculated value of Tf
S1.2.4 Length of U-Bend Tube Legs - The length of the tube legs as measured from the point of tangency of the bend and
the tube leg to the end of the tube leg shall not be less than that specified, but may exceed the specified values by the
following amounts:
