Component parts, such as large towers, high-pressure vessels, bridges, and high-pressure pipeline preheating and stress relief after welding, are also suitable for auxiliary heating of chemical pipelines and containers, making them an ideal localized heating equipment.
Flexible size changeable crawler-type electric heating elements should be selected according to the geometric shape, wall thickness, and heat treatment process requirements of the workpiece. The table below lists only a partial specification. Additionally, crawler-type heaters can be equipped with insulation materials and shells to form self-insulating heaters, which can be flat, right-angled, etc., for easy use.
