What diameter of high-temperature braided rope should I choose for industrial expansion joints?
The rope’s diameter depends on the size of the groove. As a general rule, the rope should be 10% to 20% wider than the groove to ensure effective compression. These values depend on the nature of the components.
The main difference between these two solutions is the working temperature. Zetex is stable from 500 to 700°C, while silicate fibres can withstand temperatures up to 1,000–1,200°C.
Biosoluble fibre twisted ropes and braided ropes are soft, flexible, and compressible. They retain some of their elasticity after compression, but it depends on the pressure exerted. The recovery rate also depends on the type of reinforcement used. Final Advanced Materials offers biosoluble fibre twisted ropes and braided ropes with fibreglass or stainless-steel reinforcements for ovens operating up to 1,200°C.
