Since its establishment in 1993, Dongsuh Industry Co., Ltd. has specialized in manufacturing SEALING products for power generation facilities in Korea. In particular, as we manufacture SEALING products, which are mostly used in critical power generation equipment systems, we value quality stability and develop excellent technical skills. The reliability of quality has been verified by acquiring 'Q', the highest level of safety of qualified suppliers, including ISO 9001 and 14001, and the five leading power companies under the Korea Electric Power Corp. have various quality certificates. We are also conducting R&D to continuously improve quality, improve working environment, and develop new products. Based on these efforts, we have won awards for excellent suppliers to major power generation companies in Korea and expanded our production lines by steadily increasing sales. We are now trying to move beyond the domestic market to the global market. SPIRAL WOUND GASKETOutstanding capability for high temperature and high pressure Automatic flexibility and recovery from the change of temperature, pressure, vibration and working conditionsEfficient production for any type of dimensions such as round or oval type, etc.Outstanding sealing capability as it is produced according to the pressure of unbalanced flange. Hoop and Filler materials can be selected according to special operating conditions. GRAPHITE MOLD PACKING â?¢ Graphite Tape Packing is the packing that compressed and molded in a certain dimension for easy installation. â?¢ The graphite's self-lubrication capability and low coefficient of friction allow to use in a wide range without giving damage on the reciprocating and rotary shaft. â?¢ If you want to disassemble only gland without disassembling pump and valve, you can just cut it and deliver. â?¢ You can get better sealing effects if you use with ALS910C, ALS900G and ALS955W depending on the use purpose. RING JOINT GASKET Ring joint gasket is a type of pressure energized gasket used on pipe flanges, pressure vessels, Valve bonnets handling, high pressure steam, gas, hot oil, solvent vapor at high temperature. DONGSUHs experienced technology offers many different types so that customers may select the most suitable one in accordance with operating conditions.
