Hardening and Tempering Furnaces for Pipes

From stand-alone heat treatment furnaces to complete heat treating lines, Tenova provides reliable equipment for the processing of pipe products. Tempering furnaces, hardening furnaces and innovative quenching systems are designed to meet the strict processing requirements of the modern pipe producing plant.

Tenova technology points of strength:

  • Beam system not cooled type using a special refractory casting
  • Easy mechanical system realized with hydraulic power or electromechanical
  • Easy sealing system
  • Top and bottom fired walking beam furnace design
  • Charging and discharging machines allow a flexibility to the system for handling different sizes of pipes
  • High velocity burners with free flame

Tenova typical requirements of a Hardening Furnace:

  • Process of Austenitizing: pipe reheating above Austenitizing point
  • Process of Normalizing: pipe reheating up to 920°C
  • Critical aspects:
    • Pipe could significantly bend getting into the hot furnace;
    • Pipe must be carefully handled mainly in this final phase of the treatment;
    • Small production and then very short furnaces so width length ratio high;
    • High pipe temperature uniformity to get the metallurgical requirement and keep proper shape during and after quenching.

Tenova typical requirements of a Tempering Furnace:

  • Process: pipe reheating up to 450-750°C
  • Critical aspects:
    • Very delicate process for getting the final mechanical properties of the pipe;
    • Wide product range and consequently wide range of heating temperature and soaking time;
    • Very tight temperature uniformity tolerance to get uniform mechanical properties.
