The processing of crude oil in refineries is a complex and multi- stage process in which crude oil is transformed into refined, high- quality end products or feed materials for petrochemical industry. Sealing technology for such diverse applications have to meet challenges in variousrespects; Risk of insufficient lubrication and dry running, media with a diversity of physical properties, high and low temperature ranges and the handling of hazardous substances and all other conditions which need to be controlled with absolute reliability. With a comprehensive range of API- compliant quality seals and supply systems, Sealmatic is playing a key role towards ensuring the reliability and safety of refinery processes.
