Minco Pipe - Burning Bars, Oxygen Lance Pipe, Ceramic-Coated Pipe and Exothermic Cutting Products

Minco Pipe (MPI) supplies the metals and mining industries with exothermic cutting products, castings and other items for ferrous and non-ferrous metal applications. Our range of many services and products includes burning bars, mag rods, therm rods, ceramic-coated and black oxygen lance pipes, burning bars and oxygen lane holders, ferrous and non-ferrous castings, iron plugs, oxygen probes, and thermocouples.

Burning bars for the mining industry

Burning bars are tubing or pipe filled with special wires. The burning bars are attached to a high-pressure oxygen source, ignited and maintain a sustained tip temperature of 3,000ºC to 4,000ºC.

Burning bars are ideal for quarrying applications, burning holes to set charges, cutting ferrous or non-ferrous materials and ores, tapping heats, cutting heavy scrap, cutting armor plate, demolition, and many other mining and smelting applications. Burning bars are used to cut nearly any material quickly and efficiently. Many sizes are available but a typical size burning bar is 17.1mm (outside diameter) by 3m.

ThermRods for mining equipment repair

ThermRods are small burning bars, typically 6mm to 10mm (diameter) by 0.6m to 1.5m (length), filled with a combination of tubes and wires. ThermRods are available in plain-end and quick-coupled end variations.

ThermRods are attached to a low-pressure oxygen source and have a tip temperature of 2,400ºC to 3,000ºC. Smaller burning bars are especially effective in maintenance and construction projects such as the removal of frozen bolts and pins, the cleaning of tubes, pipes and boiler tubes, and the maintenance and repair of mining equipment and other heavy equipment where precise cuts are required.

Exothermic oxygen lance pipes

MPI’s oxygen lance pipe is a hollow electric-welded tube available in various sizes, from 10.3mm to 50mm (inside diameter) and up to 6.4m (length). Oxygen lance pipes are used for cleaning slag spills, furnace maintenance and injecting oxygen or other gases into furnaces or ladles. Oxygen lancing is a reliable and economical means for tapping heats or other production operations.

Burning bar and oxygen lance holders

"Lever action" MPI holders are available for any size of burning bar and lance pipe. The holders eliminate the requirement for threaded pipe. Heat and splatter shields, ball valves and oxygen hoses are available.

Ceramic-coated pipes for molten metal applications

MPI's ceramic-coated pipe (CCP) is a carbon steel pipe with multiple, thin layers of ceramic coating both exteriorly and interiorly. The ceramic coating is resistant to slag attack and extends the life of the pipe when it is immersed into molten metal or in high temperature atmospheres. The CCP applications include powder injections, tap-hole cleaning and opening nozzles in ladles, tundishes and launders.

CCP was developed to increase the lance life beyond conventional calorized or black pipes. Due to MPI’s innovative methods of refractory deposition for interior and exterior coatings, CCP provides unequaled lance life at lower cost. A special ceramic coating has been developed for copper smelter applications.

Gas-injecting CCP for electric furnaces

CCP is used to inject gas into the submerged electric furnaces. The pipe provides a much longer life in the high-temperature furnace environment than previously used stainless-steel pipes. Using CCP to inject gas in submerged electric furnaces reduces costs and downtime for smelter production.

Some of the various uses of MPI’s CCP include the following:

• Cutting scrap, raising bath temperatures and decarburizing
• Opening nozzles in tundishes and ladles
• Injecting carbon and other powders into the electric furnace and ladle
• Opening the iron notch of a blast furnace
• Injecting argon into ladles
• Injecting argon and oxygen into the aod
• Injecting flux for degassing in aluminum melting furnaces
