Precision in tube processing is essential to ensure the quality of electric heaters. It is well known that elements coming out of the rolling mill can vary in length by about 1–2%, depending on the filling machine. Thanks to length compensation technology, dimensional variations that may occur during the production process can be eliminated.

CSM MACHINERY offers ideal solutions for compensating length differences, which also facilitate the subsequent bending phase by ensuring the correct distribution of tolerances along the heater length. Different principles exist for compensating dimensional tolerances of heating elements; therefore, at CSM Machinery we offer both a drawing solution and the Equilong, an in-line machine integrated with the reduction rolling mill.
