Double Arch Rubber Bellows are available in two types, filled arch and unfilled.
The double arch rubber expansion joint is a hand built product manufactured using high strength and high quality rubber.
The design uses two arches in a rubber spool with full rubber faces, providing good movement and flexibility, vibration control and dampening, taking up pipe misalignment, thermal expansion, relieving stress and reducing noise a long a pipeline. The double arch allows greater movements than a single arch model.
A steel flange acts as a backing ring, and to enable nuts and washers to be securely tightened. The full rubber flange face provides an excellent seal.
Filled Arch type
The filled arch type is to be used on suction pipes as the negative pressure rating is 750mm.H.g.
The filled arch type is to be used on mining slurry applications as it is hard wearing and no slurry will get trapped inside with its smooth straight filled arch bore. Other applications include de-watering suction pipes, dredging suction pipes, sand/gravel, mineral processing and tailings.
Unfilled Arch type
The unfilled arch type is good for any application where elongation, compression and angular movement is required with vibration absorption.
Custom designs are available on request.
