    • Fire sprinkler system comprising a network of CPVC pipe lengths in which at least some of the pipe lengths are interconnected with mechanical devices having resilient sealing members that are chemically compatible with the CPVC composition. Repairs and system modifications can be made without the use of solvent cement. In-line joints are formed with a coupling device including a pair of arcuate coupling segments having a first end, a second end, and an interior concave surface extending between the first end and the second end. A longitudinal channel extends along the concave surface. At least one mechanical fastener is operative to detachably connect the pair of coupling segments. A resilient annular seal is located within the longitudinal channel of each segment. A branching device connects a branch pipe to a main pipe through an orifice in the main pipe utilizing a saddle-like sealing member. The pipe assemblies are able to pass UL testing protocols for wet fire sprinkler systems.
    • 消防喷淋系统,包括CPVC管道网络,其中至少一些管道长度与具有与CPVC组合物化学相容的弹性密封构件的机械装置互连。 维修和系统修改可以在不使用溶剂水泥的情况下进行。 在线接头形成有联接装置,该联接装置包括一对弓形联接段,其具有在第一端和第二端之间延伸的第一端,第二端和内部凹面。 纵向通道沿凹面延伸。 至少一个机械紧固件可操作以可拆卸地连接该对联接段。 弹性环形密封件位于每个段的纵向通道内。 分支装置利用鞍形密封构件将分支管通过主管中的孔连接到主管。 管道组件能够通过UL防火喷淋系统的UL测试协议。
