NON-DESTRUCTIVE TEST

Eddy Current Examination according to ASTM E309shall be applied on all tubes using External Longitudinal

notch with depth of no more than 7.5% of wall thickness (maximum notch depth 0.80mm and minimum notch

depth 0.30mm) , 0.30mm maximum width and 25mm maximum length, made from the same chemistry and size

of tubing.

THE CORE DRILLING RODS SURFACE CONDITION

The tubes must have smooth surface,black surface or black phosphatized.

THE STEEL PIPES MARKING

The request information shall be marked on each tube with paint, and

each bundle shall be identified with a securely attached metal tag.

TUBES PIPES SURFACE COATING

The tubes inside and outside shall be coated with a rust inhibitor

PACKING OF ALLOY TUBES

Standard Export worthy packing, preferably in hexagonal bundle with plastic wrapped and steel strapped.
