TPS SRD SUPREME ROUGHNESS DEFINITION S u p re m e FIELDS OF APPLICATION Special fields of application require product features which go far and beyond the standard. This also includes surface quality requirements of stainless steel tubes, especially in the following applications: Chemical and Pharmaceutical Industry Semiconductor Industry / High-purity media supply Medical technology Biotechnology or with special heat exchangers types The fields of application may be diverse – however, they all have one thing in common: A plain surface guarantees a safer utilisation and the operation runs more smoothly. It, for instance, prevents the deposition of debris of aggressive media in heat exchangers or the contamination during the transport of high-purity gases. For more than 40 years now, we have continuously been enhancing the bright annealing process of our tubes. Today, we meet or exceed our customers´ high expectations without any difficulties thanks to our exceptionally smooth surface. During the process, we require no leach or acids, to ensure sustainability and to fulfill environmental requirement
