β-PPH法兰盲板，具有优异的耐化学腐蚀性、抗冲击性和耐高温性。螺栓与管路法兰对接，实现管道端口的完全封堵与可靠隔离。
β-PPH法兰盲板是一种高性能的管道封堵配件，中间无孔，通过螺栓与管路上的法兰对接，实现管道端口的完全封堵与可靠隔离。江苏吉庆管材集团使用的是全新β改性的均聚聚丙烯原料，具有优异的耐化学腐蚀性、抗冲击性和耐高温性。
一是管道端口封堵隔离——用于临时停用的管线端口、待扩展的预留口、反应釜检修盲断等场景，完全隔离介质，避免渗漏污染；
二是系统分段试压与安全防护——在管道系统试压、试漏及设备检修时作为隔离段，保障作业安全，同时在管路系统需要扩展时保留后续对接条件。
1. 化工行业：管线临时封堵与永久隔离
2. 建筑给排水：高位水箱备用口与管网改造
3. 制药与纯水系统：洁净管路隔离
4. 环保工程：污水处理与废气系统
