Onis Line Blinds physically spread the pipe. All Onis Line Blinds moving parts are outside of the process, and there is no flow reduction in the pipe and no room for product build-up. The bodies of Onis Line Blinds are made from solid forgings and are not welded flanges. Onis offers a one year warranty (additional upon request). Installation support and on-site training for operators and maintenance personnel are also available.
