Preheating of field joint coating as a part of the pipeline welding is often a critical phase of the pipeline construction: a fast, accurate and uniform heating, especially on large diameters, is often not easy to achieve with traditional gas flame and resistance heating systems.

When higher temperatures are required or even in peculiar installations sites, such as extremely cold regions, the use of induction heating systems is not only recommended but, in most cases, it represents the easiest and most reliable method to meet the cycle times demanded by the industry, in order to get an accurate and uniform heating around the full circumference and bandwidth of the weld joint.

LK2 offers different types of Induction Heating Systems to suit a wide range of pipeline diameters and temperature requirements. Induction coils are powered by either diesel or rotary converter generators.
