Features and Benefits

· Typical Pitting Resistance Equivalent (PRE) of 27 to 29 (15-15LC® Mod material) and 31 to 33 (15-15HS® Max material) exceeding the American Petroleum Institute (API) standard of 21 to 23.

· Extra-length tool joints provide ample space to re-cut the connections, reduce the wear rate on the OD and extend the service life.

· Proprietary compressive treated ID reduces stress corrosion cracking even under the most extreme conditions.

· Centre upsets protect tube from OD wear while at the same time reducing the risk of differential sticking.

· All connections cut to API standards with bore back box & stress relief pin as standard features.

· Each joint delivered complete with mill material certification and 3rd party connection inspection report to API Specification 7 standards.
