Metals Testing

Tensile tests The methods used to test tensile specimens taken from or consisting of pipes vary according to the product form. Small, thin pipes are crushed at the ends for a sufficient length and then pulled, while cores are used in larger diameter pipes to prevent pre-damage through crushing. With larger pipes, standardized specimens are produced from material removed from the wall of the pipe. It is possible that specimens (taken longitudinally) may display the curve of the pipe radius; for reliable, pre-damage-free testing this radius should be compensated for with suitably shaped counter
