TuffRod Drill Pipe is made to the industry standard S135 Specification.
- Tensile Strength 145,000 PSI (The maximum stress the material will sustain before fracture.)
- Yield Strength 135,000 PSI (The stress corresponding to a specified permanent (plastic) deformation – the point at which the material yields and won’t spring back)
- Elongation .7% EUL (The increase in the gauge length, measured after fracture of the specimen within the gauge length, usually expressed as a percentage of the original gauge length / EUL Extension Under Load)
