“Welding rollers made from ceramic: A service life 20 to 30 times that of welding rollers made from steel and significantly fewer signs of wear.”
Fully finished longitudinally welded pipes are produced from a flat metal belt. The metal sheet is fed in through welding rollers to ensure that the mold fits perfectly and the necessary longitudinal seam is cleanly welded. This is precisely where extreme precision is required, where the edges of the metal are positioned at exact intervals. However, the rollers are also subject to heavy loads here, which can lead to wear.
CeramTec silicon nitride welding rollers can achieve a service life 20 to 30 times that of welding rollers made from steel in longitudinal pipe welding. Silicon nitride ceramics demonstrate significantly fewer signs of wear and are able to ensure the quality of the welding seam for longer periods.
