Steel

Tubetech uses only steel that meets exact specifications for chemistry, tolerances, finishes and coil weights. Every coil is accompanied by a certificate of chemistry and every one is weighed, inspected visually, checked for gauge accuracy and tested for surface hardness and finish.

Nondestructive and Destructive Testing

Nondestructive testing is performed on the mill using an eddy current tester, which tests for weld and steel integrity and for imperfections not easily seen on visual inspection.

Destructive testing takes three forms: In one, an expansion plug expands the tube hydraulically 25% to 30% of it's diameter to test weld integrity, weld seam alignment and ductility. A second flattens the tube wall-to-wall to examine weld integrity. The third, a cone expansion test, checks the tube's ability to be flared.

 

Final Inspection

Before shipment, tubes are inspected to check surface, wall thickness and length.
