High-strength steels are growing in popularity as they offer increased performance at reduced weight and cost. These performance gains are particularly advantageous in harsh environments such as offshore wind farms.
This trend is driving demand for preheating, an essential step to maintain the tensile strength and integrity of steel by avoiding defects such as cracking. In fact, preheating is recommended and even mandated by many standards and codes of practice. It is usually applied immediately prior to cutting or welding, providing additional energy and allowing thicker sections to be cut and welded with better quality.
Successful preheating is achieved through precise temperature control and uniform heat distribution throughout the thickness of the material. The preheating temperature depends on the type and thickness of the material, and the subsequent process. It can be an extremely complex step and the optimum parameters vary from one application to another.
Optimum Preheating Performance
The productivity of preheating is greatly enhanced with acetylene, applied with best-in-class equipment. Because we understand that off-the-shelf solutions do not always fit individual needs, we have developed a range of specially designed burners and nozzles, engineered for reliable acetylene flames and long-lasting use. In addition, we customise these burners to maximise your thermal efficiency values.
Designed for ease of automation, our LINDOFLAMM® range of special burners offers the greatest possible cost efficiency and highest safety standards. Our end-to-end offering extends from acetylene supply solutions and burners to electronic components and supporting services.
