Rotary Unions Exporter
PULP & PAPER INDUSTRY
Rota-Tech paper applications span the production chain from the raw pulp and paper mills, to the downstream paper converters. Mills use steam joint and siphon systems and water unions for heating and cooling. Converters use rotating unions for heating and cooling rolls, as well as winders with air clutches and brakes. Massive equipment is used to manufacture paper rolls from raw pulp.
Rota-Tech rotating unions are used in the headbox, press rolls and nip rolls, while the dryer section employs Rota-Tech steam joints and siphons for steam and condensate removal. Calendar rolls require unions for either steam or hot water. Large parent rolls of paper from the mill are placed on winders with air clutches and brakes so that paper rolls can be heated or cooled, coated, cut, slit or cured. Rota-Tech rotating unions are used for heating and cooling rolls. The pulp is fed to a paper machine where it is formed as a paper web and the water is removed from it by pressing and drying. Drying involves using air or heat to remove water from the paper sheets. Various forms of heated drying mechanisms are used. On the paper machine, the most common is the steam heated can dryer.
In paper sector; rolls which used to dry the wet paper, must be heated. To heat these rolls; hot oil or steam is used. While rolls rotate, supply and return lines are stationary. High Temperature Rotating Joints are used to connect these stationary pipes to rotating rolls without any leakage.
