Oil & Gas

Our industrial line of hard-facing and welding wire is utilized heavily in the oil & gas industry.

Hardfacing material is applied to the contact surfaces and moving areas of the valve, such as the valve seat, to provide wear resistance and corrosion resistance. Our wire is used to hardface valves in markets such as oil & gas, nuclear power, chemical, mining, and refining. Valve components are hardfaced with Our cobalt-based material. It is available in three forms: cast rod, small diameter TIG wire, and powder. The cast rod is very prevalent in the industry and it’s used in SMAW sometimes, while the small diameter wire is suitable for automated and robotic welding. Automation has significant consumable advantages over traditional methods, allowing reduced downtime due to switching out material, diminished excess labor, and retention of the valuable cobalt-based material.

Our cobalt based wire is primarily applied as an overlay for carbon steel, stainless steel, and nickel-based alloys. For example, hardfacing valve seat and plugs using Co6, a cobalt-based material with a nominal composition of Co (Bal), Cr (29), W (5), and C (1), will produce a wear and corrosion resistant coating extending the life of the application. Many valves that involve high pressure, high temperature steam require cobalt based alloys to withstand their harsh operating environment.

Our products demonstrate the necessary hardness characteristics and wear resistance properties to be used in valve applications. Resistance to high temperatures is also a critical property of these hardfacing alloys. Typical applications include:

  • Ball valves
  • Gate valves
  • Butterfly valves
  • Diaphragm Valves

Our rapidly growing product line supplies most of the hardfacing demands of the oil & gas industry. Our products are ideal for adhesive wear, contact fatigue, corrosion, and erosion. Their strength and ability to withstand these wear factors make them one of the most exceptional hardfacing consumables on the market. They are available in wires, continuous cast rod (3.2mm and up), and powder.
