Mining
HRI is able to service various units within the mining industry.
Vessels
When vessels crack or rupture, they can leak hazardous and extremely hot materials at dangerous pressures that pose a considerable safety risk to workers in the immediate area. HRI technicians can repair external ruptures on vessels, often while they are in full operation. This allows workers to reenter the area as quickly as possible and results in a minimal decline in operation during the repair period.
In addition to mechanical and welding repairs, HRI technicians can perform inspections, including NDT ultrasound testing, on lines and vessel walls. Our technicians have developed specific repair procedures that consider the integrity of the parent material, and they will design a detailed repair plan that focuses on the requirements of your material.
Ductwork
Ducts in the ore smelting process become superheated, which can make repairs problematic for regular maintenance crews. HRI performs welding and mechanical repairs to heated ductwork surrounding both smelters and precipitators while the units remain online. Roasters HRI can perform high-temperature vacuuming of ash deposits in confined areas, and we are happy to schedule in advance routine maintenance to the unit.
