Welding forming roll

Improve process reliability of longitudinal tube and tube welding

The welding roller made of silicon nitride ceramic is harder, the hardness is more than HV1400, and the service life is traditional alloy steel welding 20 to 30 times of the receiving roller.

Longitudinal welded pipes are used in a variety of applications, such as heating equipment or pipes. No matter what field they are manufactured for:Welding rollers ensure safe and accurate longitudinal welding. XY uses silicon nitride to make these welding rollers.Silicon ceramic material has resistance to high stress, high hardness, and wear resistance, so it has long service life.

The coated longitudinal welded pipe is made of flat metal strip. The metal sheet is fed into the welding roller to ensure the perfect fit of the mold,longitudinal seams are necessary for clean welding. This is the reason that extremely high accuracy is officially required, and the metal edges are positioned at precise intervals.However, the rollers are also subjected to load-bearing loads and may wear out. The use of XY silicon nitride in longitudinal tube welding life expectancy is 20 to 30 times that of iron welding rollers. Silicon nitride ceramics significantly reduce wear and ensure a longer period of time quality of the weld.
