Non-metallic expansion joints suit utilities, municipalities, smelters, steel mills, petrochemical/chemical plants, cement plants, pulp/paper mills, waste heat recovery and cogeneration facilities.
Wahlco Metroflex has available non-metallic expansion joints for utilities, municipalities, smelters, steel mills, refineries, petrochemical plants, chemical plants, cement plants, pulp and paper mills, waste heat recovery and cogeneration facilities.
The joints can handle extreme heat conditions as well as abrasive and caustic gases, while meeting requirements for economy of installation, operation and energy efficiency.
Reliability is achieved with designs and features such as the mounting of belts with steel channels, instead of flatbars, for stronger and more consistent clamping force.
Two classes of advanced material are used for the belts - durable elastomers and rugged flouroplastics.
The firm's Supratef flouroplastic materials are a combination of fluorocarbon resins for chemical resistance and woven fibreglass reinforcement for high strength.
Supratef fabric is engineered to withstand the ductwork's full temperature range, even without the added protection of the firm's joint cavity insulation.
Each expansion joint is built to meet the requirements of each application, based on various model designs that Wahlco Metroflex has proven and refined.
The company has an inventory of expansion joint raw materials, permitting it in many cases to manufacture a belt replacement in one day for immediate delivery.
