Conforma Clad Inc. offers rotary airlock protection with tungsten carbide tiles. Areas of the airlock that are protected by tungsten carbide tiles include the tips of the veins, the entire inner diameter of the housing and the end plates. Airlocks can be rebuilt to specified tolerances; using either carbide or ceramic tiles depending on customer requirements. Machining and grinding capabilities allow modification of the areas to be protected so that they can accept any specified coating or lining, which can then be ground to meet exact tolerances.
