Refrex® (Multi) Tube Bellows

Refrex® multi tube bellows are flexible seals around multiple pipe penetrations in the roof of a petrochemical furnace. They prevent cold air ingress due to under pressure and are to absorb both axial and lateral movements. Refrex® multi tube bellows can be applied up to 1300°C.

Due to the use of high-quality high-temperature fabrics, the process pipes are not limited in their movements as a result of thermal expansion of process pipes. The design of the Refrex® 1230/1430 tube bellows ensures that the seal between the opening in the roof and the process pipes is optimal in order to minimise cold air ingress. This saves a considerable amount of energy.

We can provide you with the right seal!
