To ensure compliance with relevant standards in the food and medical technology sector, Schoeller Werk will from now on use a new surface roughness meter (profilometer). This allows stainless steel tubes to be precisely tested at each 10th or 20th standard production length.

What is more, the leading manufacturer of longitudinally welded stainless steel tubes can now measure the surface roughness values in both longitudinal and transverse directions. Customers will in future benefit from optimised products with even faster availability.

The manufacture of machine or product parts for medical technology or the food sector brings with it a great responsibility: comprehensive and precise quality control is essential. That is why Schoeller Werk invests continually in the latest technology, so it can supply its customers with a perfect finished product.

The firm has recently introduced a new device for the measurement of surface roughness values. The MarSurf GD 120 is controlled by software and permits the creation of its own measurement routines. In this way, Schoeller Werk can use pre-programmed settings for material samples, without having to alter the device setting manually to test a tube of different diameter.

Thanks to a probe with a dimension of 0.5 mm in the probe tip area, materials with an inner diameter of up to one millimetre can be precisely inspected. After each measurement, the device records a measurement protocol containing all information relevant to the test concerned. In particular, the measurement and the documentation of surface roughness values are simplified by the new device.
