NanoSteel coating tapped for mine project

PROVIDENCE – Canadian wear-resistant casing manufacturer Trimay Wear Plate Ltd. has selected The NanoSteel Co. Inc.’s Super Hard Steel weld alloy to improve the wear protection of its steel concrete slick line at a mine in northern Canada.

The slick line, a 1,968-foot-long vertical borehole used for delivering concrete to backfill mined-out sections and reinforce rock walls, consists of NanoSteel-clad API L80 steel casing and Trimay’s proprietary threaded-joint system.

Coated in NanoSteel’s wear-resistant Super Hard Steel alloy, the slick line will see a wear rate of 1 millimeter thickness loss per every 320,000 tons of concrete delivered through the line, or more than thirty times the wear resistance of an uncoated API L80 steel casing, which would experience a wear rate of 1 millimeter of thickness loss per every 10,500 tons of concrete.

The service life of the Trimay-NanoSteel system is projected to achieve full “life-of-mine” duration, exceeding 19 years, NanoSteel said.

“The high hardness and toughness properties provided by our weld overlay result in the improved wear performance for this application,” said Tom Santos, vice president and general manager of coatings for NanoSteel. “Because of this, a slick line clad with our material eliminates several replacement cycles for a life-of-mine solution.”

The steel concrete slick line will be installed at the mine in the first quarter of 2014 and is the second line of identical configuration commissioned by Trimay for the same mine.
