# 939/939B系列PTFE波纹软管 > 派克波纹PTFE软管，具有优异的柔韧性和耐扭结能力，在化学品传输、高温液压和非常狭小的管路布置空间应用场合中，能表现出优异的产品性能。 所属技术：流体连接 ## 系列介绍 派克939/939B系列波纹PTFE软管，具有优异的柔韧性和耐扭结能力，能成功地应用于化学品传输、高温液压和非常狭小的管路布置空间应用场合。另外，其易弯曲的能力也使得其最小弯曲半径小于919/919B软管，以简化管路的布置和方便软管的安装。该系列软管既可以提供天然PTFE、符合FDA要求的芯管产品939，也可以提供导走静电的芯管产品939B，这取决于在流体介质传输过程中是否会有静电荷的产生。 两种芯管类型的软管产品都采用304不锈钢丝编织的增强结构，使得该系列软管产品能广泛地使用于流体处理、交通和军事等市场应用中，并提供持久牢固、灵活多变、耐扭结的解决方案。 市场: • 流体处理 • 交通 • 军事 • 工业 特性/优点： • 优异的柔韧性 • 优异的耐扭结能力以简化管路的布置和软管的安装 • 优异的化学兼容性 • 耐高温的能力 应用: • 化学品传输 • 一般液压 • 非常狭小的管路布置空间的各种应用 • 高温流体介质的传输 证书/符合标准: • FDA CFR 177.1550 (仅939软管) 技术参数: • 芯管:939 - 符合FDA要求的天然PTFE橡胶 939B - 黑色静电耗散的PTFE材料 • 增强层:304不锈钢钢丝编织 • 静电耗散芯管939B软管仅用于传输不导电流体，比如油品、油漆、燃油、蒸汽等等。 • 该系列软管不建议用于蒸汽-冷水循环的应用场合 • 73°F (23°C)时其最小爆破压力是最大工作压力的4倍。 • 与93N系列软管接头匹配扣压 • 软管内径I.D.采用公称尺寸 • 软管外径O.D.采用最大尺寸公差设计 ## 技术参数 | 参数 | 值 | 单位 | | --- | --- | --- | | 设计因素 | 4 | | | 介质 | Chemicals, Lubricants (Oils), Petroleum Hydraulic Fluids, Water, Food Abrasive Powders, Food & Beverage, Industrial Fluids, Industrial Gases, Steam, Fuels (Oil), Air Use with static-dissipative hose, Inert Gases | | | 符合规格 | FDA 21 CFR 177.1550 (Natural -
