金属缠绕垫片采用优质SUS304、SUS316("V”形或“W”形)金属带及其它合金材料与石墨、石棉、聚四氟乙烯、无石棉等软性材料相互交替重迭螺旋缠绕而成，在开始及末端用点焊方式将金属带固定。金属缠绕垫片为半金属密合垫中回弹性最佳的垫片，金属缠绕垫片结构密度可依据不同的锁紧力要求来制作，并利用内外钢环来控制其最大压紧度，缠绕垫片接触的法兰密封面的表面精度要求不高。金属缠绕垫片特别适用于负荷不均匀、接合力易松弛，温度与压力周期性变化、有冲击或震动的场合。缠绕垫片是阀门、泵、换热器、塔、人孔、手孔等法兰连接处理想的静密封选择。

Metal spiral wound gasket adopts high-quality SuS304 or $US316 ("V" or '"W"shape) metal stripsother alloy materials and some flexible materials like graphite, asbestos,PTE and non-asbestos, which areoverlapped and wound spirally with each other, The metal strips are fixed on the initial and terminal ends bymeans of spot welding, The metal spirally-wound gasket has the best resilien ce among the semi-metal hermeticgaskets.lts structural density can be made subject to different locking forces. Also the internal and externalsteel rings can be used to control its maximum compaction, it's not demanding for the surface precision ofthe flange sealing surface contacting the spirally-wound gasket. lt's especially applicable for suchoccasions as uneven load, slack ioint, periodical changes of temperature and pressure, impact or vibration.It's an ideal static seal element for flange connection in valves, pumps, heat exchangers, towers, manholeshandholes and so on.
