DIMENSIONS AND TOLERANCES

Material:  

Tubing made from low-carbon steel confirmting to the following chemical compostion.

MECHANICAL PROPERTIES:

The finished tubing have mechanical properties of following table:

Quality:

Lengths of finished tubing is reasonably stragiht and have smooth ends free from burrs.

Tubing is free from scale and injurious defects and have a workmanlike finish.

Surface imperfections such as handling marks, die marks, or shallow pits shall not be considered injurious

defects provided the imperfections are within the tolerance specified for diameter and wall thickness.

The removal of such surface imperfections is not required.
