Major investment to safely harvest and refine our natural resources throughout the world has caused the marketplace to focus more broadly on the quality of steel pipe for oil casing and pipeline transportation systems. ISO 6892-1, ASTM A370, API5L, and ISO 3183 specifications contain tensile testing procedures which can present a variety of challenges based on the shape of the pipe, the wall thickness, and the radius.

The challenges of tension testing of pipe and tube to these standards:

Gripping full section pipe/tube

Obtaining suitable strain measurements
