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.

 

Packing:

Packed in wooden box or bundles protected with plastic paper, and suitably protected for sea-worthily delivery or as requested.

 

The Product marking shall include the ASTM A210 or ASME SA210, size, heat no., Lot No. and Manufacture name or logo.
