- Graphite Tape Packing is the packing that compressed and molded in a certain dimension for easy installation. - 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. - If you want to disassemble only gland without disassembling pump and valve, you can just cut it and deliver. - You can get better sealing effects if you use with ALS910C, ALS900G and ALS955W depending on the use purpose.

TECHNICAL DATA - Tensile Strength : 28 ~ 35 MPa - Elongation : 200 ~ 400% - Temperature : up to 500°F (260 C) - Hardness : R25 (Rockwell) Application - Control valves, Rod, piston FEATURES - Elimination of costly seal failure or blowouts - Reduced installation costs - Reduced equipment downtime with exact seal specifications - Reduced inventory costs - Lower friction / Friction a measurement of the resistance to sliding between a seal and hardware surfaces, is directly related to seal material coefficient of friction and the total load. - Longer Life / Individual sealing rings expand under bolt loading to maintain a tight, virtually leak proof set with up to 50% longer services over braided styles.
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.

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. MECHANICAL PACKING (VARIOUS MODELS DEPENDING ON CONDITON) PTFE V-PACKING SPRING ENERGIZED SEAL
Material : Graphite, PTFE, etc. Application : - Valve - Pump (Power plant, boiler water supply and condensate pump, etc.) - SOOT BLOWER - All other places requiring efficient sealing in the factory Feature : This braid packing adds the molybdenum-based anti-corrosion agent to the high purity flexible graphite tape at below 50ppm Chloride which is equivalent to the nuclear power level with high degree of thermal conductivity and low coefficient of the friction, and it is the multi-purpose packing designed for use of both valves and pumps as it is more endurable with the continuous filament carbon fiber inside the braid as well as the graphite inside in order to be endurable at high RPM and pressure. Therefore it is not necessary to use End Ring for prevention of extrusion. Moreover, the most optimal flexibility is guaranteed with the special braiding technology of DONGSUH ALS900G, so that the adjustment or harmonization with the shaft or stem is outstanding as the entire distribution is uniformed even if it is mounted in any shaft or stem size. No wearing or scratching of the shaft or stem can be found due to the self-lubricating function of the high purity graphite while decreasing the packing life span significantly. DONGSUH ALS900G is suitable for overall conditions in the factory such as valve and pumps, etc. Using with ALS350 Graphite Molding Packing as End Ring will get better sealing effect.
[Spiral Wound Gasket] Material Filler: GRAPHITE, PTFE, INCONEL, etc. Hoop: SUS304, SUS316L, etc. Feature The spiral wound gasket is the most ideal type having flexibility and recovery which are essential for high temperature and high pressure among semimetal gaskets. It is wound in spiral combined with V-type metal thin hoop and non-ferrous material filler. The winding start part and end part are wound by the hoop over several times and then both edge is processed by spot welding to make the gasket. The gasket has outstanding capability as it features unique structure with elastic metal and flexible filler. - Outstanding capability for high temperature and high pressure - Automatic flexibility and recovery from the change of temperature, pressure, vibration and working conditions - Efficient 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. [METAL GAKSET] - Ring Joint Gasket - Serrated Gasket - Double Jacketed Gasket - Metal O-Ring
1: Optimal Sealing by O-Ring Highly durable Teflon O-Ring was used and special coating was done at the contacting point of O-Ring to ensure perfect Sealing and secured operation at fire detecting. 2: Shock proof structure with steel ball support method With 8 steel ball support structure for shock esistance, it Is reliably safe from external impact and free from damage And leakage 3: Low Assembly Load By minimizing the assembly load with o-Ring Sealing Method, safety is secured with low pressure inside the Head. 4: Excellent Design As the head is installed in the building, aesthetic design By minimizing heat detecting with small head was made.
