　钢包垫片系指内部用非金属材料(柔性石墨聚四氟乙烯、石棉橡胶板、陶瓷纤维）等，外部用特定的冷作工艺包覆金属薄板的复合型垫片，按垫片截面通常分为平面型包覆及波纹型包覆两种，是最传统的一种密合垫片，适用于热交换器、压力容器、泵、阀及法兰面密封。但回弹力有限，需要求法兰表面平坦及紧固力很高才能达到良好效果。根据不同材料可以组合成304不锈钢包石棉包覆垫片，不锈钢包石墨包覆垫片等多种形式。              
　　金属缠绕垫片（基本型）是采用标准优质的SS304、SS316（“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、无石棉等柔性材料相互重叠螺旋缠绕，并在开始及末端用点焊方式将金属带固定而成。              
　　性能：耐高温、高压、耐腐蚀，具有良好的压缩率和回弹率。              
　　应用：石油、化工、电力、冶金、船舶、造纸、医药等法兰连接处的管、阀、泵、人孔、压力容器及              
　　换热设备的密封部位是理想的静密封材料。              
　　不锈钢带形状：“V”“W”"SUS""U"。              
　　不锈钢带材质：A3、304，304L，316，316L，蒙乃尔        Monel，钛材Ta        。
