TD-200A 高压安全阀门盘根，又称全镍基盘根，通常用名：镍丝网包覆盘根。该盘根由高纯低硫膨胀石墨线编织而成，并在每根石墨线中加入了因科镍（Inconel）合金丝，在每根线的外面再用因科镍丝进行网状编织。它保留了TD-200I型镍丝石墨盘根的所有内在优点，即具有良好的热传导性，耐化学性及自润滑，同时全镍基金属包覆结构大大提高了盘根的机械强度，使盘根更致密，更结实。同时经特殊处理的玻纤丝代替了传统的棉纱，避免了高温下热烧失的弊病，以充分胜任超高温、超高压工况的阀门密封TD-200A Mesh Reinforced graphite packing the packing made of low-sulphur expanded graphite yarns with corrosion inhibitor, reinforced with Inco
nel wire. Each yarn is round braided with Inco
nel mesh again. The exclusive packing is formable, yet tough. Rated in steam service 550bar, maintains integrity in steam up to 850°C. It is a cost-effective as well as a co
nfident choice..适应于超高温、超高压工况的阀门密封.Designed for high temperature valve with high pressure. 服务范围 SERVICE LIMITS
