CUTTING, BEVELLING
Pipe cutting and Bevelling machine
The only beveling machine designed with the end users based on their know-how
DWT offers equipment for beveling thick pipes with a historical know-how from the technicians working on site with these machines. DWT GmbH in Essen, Germany manufactures equipment for the preparation and chamfering of pipes before welding, used for thick-walled pipes, boiler pipe panels and water-cooled walls. Pipe preparation is the first and most important step in the process before welding. Especially for thick-walled pipes, the pre-weld preparation bevel must be perfect to obtain the quality welding result. We offer a unique product range for the needs of the international pipe installation industry, where the materials to be processed are becoming more and more sophisticated. Nowadays the increase in thickness and the steels are more and more difficult to machine. Our beveling machines can meet the needs of the modern world regardless of thickness and material. The portable machines are lightweight so that they can be handled by one man in different job site configurations.
