石墨填料环/ Graphite seal ring/1015/0911

产品特点: Product features 

由石墨带压制而成，无任何填充剂和粘接剂，纯度大于98%，具有膨胀石墨材料的各项特性，能经受温度和压力的剧烈交变，是各种填料函的理想密封元件。填料环标准截面为方形，也可加工成楔形或V形碗形等，产品有阀门专用填料（石墨环）、石墨纸、石墨板、石墨波纹带、自密封、碗型垫等。材料还可以根据要求添加钢丝等制做增强型模压填料环适合高压部位密封，常用于各种化学液体，强碱、强酸、有机溶剂、液氧等强腐蚀性环境。 

It is pressed by graphite tape, without any filler and adhesive, with a purity of more than 98%. It has various characteristics of expanded graphite material, and can withstand severe alternation of temperature and pressure. It is an ideal sealing element for various stuffing boxes. The standard section of the packing ring is square, and it can also be processed into wedge-shaped or V-shaped bowl. The products include special valve packing (graphite ring), graphite paper, graphite plate, graphite corrugated belt, self sealing, bowl gasket, etc. The materials can also be used to make reinforced molded packing rings by adding steel wires as required, which are suitable for sealing high-pressure parts and are commonly used in various chemical liquids, strong alkalis, strong acids, organic solvents, liquid oxygen and other strong corrosive environments. 

应用范围: Application Scope
