Spirally wound gaskets are constructed of a continuous strip of preformed V shaped metal which is wound spirally with pure graphite and inorganic fibers as fillers instead of asbestos, which is excellent in gas sealing and heat resistance. The complex combination of a single metal ply and soft filler offers greater resiliency than any other metallic gasket and therefore provides good compensation for relaxation, temperature or pressure cycling, and shock or vibration. Because there is a variety of sizes, shapes, and materials available such as copper, iron, stainless steel, monel, aluminium, and combinations of metal, pure graphite and inorganic fibers, please specify the details referring to the illustration below. A sample is acceptable for order made gaskets, but the standard shapes are illustrated below for your information. Applications: Pipe flanges, tanks, valve bonnets and other equipment. Size D1: 19mm, D2: 25mm, D3: 38mm. When ordering please specify the material from a)Expanded Graphite, b) Non Asbestos, c) PTFE.
螺旋缠绕垫片是由一条连续的预制V型金属制成,用纯石墨和无机纤维代替石棉作为填料螺旋缠绕而成,具有良好的气密性和耐热性。单一金属层和软填料的复杂组合提供了比任何其他金属垫片更大的弹性,因此可以很好地补偿松弛、温度或压力循环以及冲击或振动。由于有多种尺寸、形状和材料可供选择,如铜、铁、不锈钢、蒙乃尔、铝,以及金属、纯石墨和无机纤维的组合,请参考下图详细说明。定做的垫圈可以接受样品,但标准形状如下所示,供您参考。用途:管法兰、储罐、阀帽等设备。尺寸D1:19 mm,D2:25 mm,D3:38 mm。订购时请指定a)膨胀石墨,b)非石棉,c)聚四氟乙烯的材料。
