    Application of ZH Induction Heating System for Pipeline Heating of Pipeline Construction

  • Preheating before pipe welding
  • In the construction of long-distance pipeline, the preheating of welding is very important because it can slow down the cooling rate after welding, make hydrogen diffuse and escape in the weld metal, and avoid cracking caused by hydrogen. It can also reduce the hardening degree of weld and heat affected zone to improve the crack resistance of welded joints. Preheating can reduce welding stress. Uniform local preheating or overall preheating will reduce the temperature of the welding zone between welding machines (also known as temperature gradient). Preheating can reduce the bonding degree of the welding structure, especially the bonding degree of the corner joint, reduce the occurrence of cracks, and increase the preheating temperature.
  • Preheating before coating
  • Preheating before coating can remove the moisture on the pipe surface, so that after the primer is applied, it can play a good moisture-proof and anti-corrosion effect, and avoid the generation of bubbles during the construction process. For example, if the moisture on the pipe surface is not removed, after the primer is applied, the heat shrinkable band is easy to cause poor bonding effect, generate bubbles or the separation of the primer and the heat shrinkable band, thus losing the role of anti-corrosion and sealing. Induction Heating System for Pipeline Heating of Pipeline Construction is the important equipment for Preheating before coating.
  • Heat Treatment
  • Welded parts are subject to high pressure whilst in operation and require a further process of stress relieving and tempering . This particular heat treatment is called post weld heat treatment ( PWHT ), a controlled heating cycle consisting of a heating phase , a holding time and a controlled cooling . Our induction heating systems are the best choice when the parts to be heated are too large or non – transportable and the process cannot be carried out in a furnace . When the parts vary and are large in number , we recommend our resistance Induction Heating System for Pipeline Heating of Pipeline Construction .
  • Anticorrosive Coating
  • Induction Heating System for Pipeline Heating of Pipeline Construction can specially protective coatings , such as FBE or heat shrink sleeves , are always applied on pipelines tubes , except for the jointing area which is coated with the protective material once the joint has been welded . Induction heating is used to preheat the pipe surface as this prevents oxidation and allows the insulating material to adhere well and quickly , without affecting the adjacent areas . Our induction heating generators and coils can be used for any coating applications onshore , offshore and in coating plants .
