High Frequency Post Weld Heat Treatment Equipment

Brief introduction of Canroon high frequency post weld heat treatment equipment:

Induction post weld heat treatment machine is designed and manufactured by Canroon fused for pipes PWHT/post weld heat treatment (DHT dehydrogenation heat treatment, ISR intermediate stress relief), widely applied and welcomed by oil&gas piping, offshore platform construction, and power plant construction & repair.

For PWHT, the suitable pipe size with Diameter of 200-1600mm and Thickness of 25-120mm, heating temperature will reach 788℃ at most.

Besides, application of welding preheat, joint anti-corrosion coating and shrink fitting are also very efficient.

Features of high frequency post weld heat treatment equipment:

• precise control

•  

  The heat is induced within the part itself by alternating electrical current, thus uniform temperature throughout the heating zone is realized.

  This uniquely energy-efficient process converts up to 90% of the expended energy into useful heat, and time-to-temperature is faster than conventional processes due to the method of applying heat, reducing cycle time.

• Uniform Heating

•  

  Once fault occurs, CR2000 will act with display of fault code, which was detailed explained in the manual book.

• High Efficiency

•  

  Due to modular design, the maintance will be easy and low-cost.

• Self Diagnosis

•  

  Fault codes will display and be recorded for reference, and system will respond with protection action like shutdown once fault occurs such as open-loop output or short out.

• Easy Maintenenace

•  

  The interface offers two basic control mode to choose including temperature control and power control. The former one has 4 modes of preheat, bake-out, PWHT, custom. The last one has 2 modes ofconstant power and power VS time. Each mode offers different parameters to set. Thus brings the benefit of wide applicability and precise control.

• Fault Record

•  

  We have display board to show working parameters, and temperature recorder can feedback PWHT curve, you can print it.
