Extreme-Pressure Pipe Fitting 极高压不锈钢螺纹管件接头 替代品
核心特性与用途
高强度耐压：适用于液压流体管路中连接设备，可承受极端压力。
耐腐蚀性能：316 不锈钢材质具备优异的抗腐蚀能力，适合腐蚀性环境。
常见类型与功能
穿墙接头（Through-Wall Fittings）
别称：隔板接头（Bulkhead Couplings）。
功能：穿过墙体安装，形成流体进出口；安装时需将垫圈置于墙内侧以确保密封。
90° 弯头过渡接头（Female x Male 90° Elbow Adapters）
别称：街头弯头（Street Elbows），用于改变管路方向。
直通三通（Inline Tees）与直角三通（Right-Angle Tees）
别称：分支三通（Branch Tees）与运行三通（Run Tees），用于管路分流或汇合。
螺纹类型与密封设计
螺纹类型 | 兼容性 / 密封特性 |
NPTF（Dryseal） | 与 NPT 螺纹兼容，干密封设计，无需额外密封剂。 |
BSPP、公制螺纹 | 采用垫圈或垫圈 + 垫片组合防漏。 |
UN/UNF（SAE Straight） | 别称 O 型圈凸台螺纹，外螺纹端通过垫圈密封，防止泄漏。 |
应用场景
适用于高压液压系统、化工设备、海洋工程等对耐压性和耐腐蚀性要求高的场景，确保管路连接的可靠性与密封性。
