These permissible variations in length apply to tubes before bending. They apply to cut lengths up to and including 24 ft [7.3 m]. For lengths greater than 24 ft [7.3 m], the above over-tolerances shall be increased by 1⁄8 in. [3 mm] for each 10 ft [3 m] or fraction thereof over 24 ft or 1⁄2 in. [13 mm], whichever is the lesser.

 
 
 

 

SA192 Tube Hydrostatic Test Pressures

Each tube shall be subjected to the hydrostatic pressure test, or instead of this test, a nondestructive test may be used when specified by the purchaser.

SA192 Flattening Test

One flattening test shall be made on specimens from each end of two tubes selected from each lot or fraction thereof.

SA192 Flaring Test

One flaring test shall be made on specie- men from each end of two tubes selected from each lot or fraction thereof. These tubes shall be selected apart from those used for the flattening test.
