They are important in the design of gravity-fed equipment. They are designed to reduce the speed of grain movement by gravity, which makes it possible to reduce the risk of injury to the grain when changing the direction of its movement through gravity pipes. Available in round and square sections. Flange bolted fasteners. They are installed on straight sections in front of distributors, conveyors, elevators, silos, separators, grain dryers. They allow several times to extend the service life of gravity pipes and other equipment.
