SYSTEM AND METHOD OF ASSEMBLY OF ＣＰＶＣ FIRE SPRINKLER SYSTEM EMPLOYING MECHANICAL COUPLINGS AND SUPPORTS

摘要

Fire sprinkler system, at least some of the pipes with CPVC pipe composites and chemically compatible elastomeric sealing member comprises a CPVC pipe of a mechanical device and interconnected group. Maintenance and system change can be performed without the use of solvent cement. An in-line joint is formed with a coupling device comprising a first end, a second end, and a pair of arcuate coupling having a concave inner surface extending between said first end and a second end segeumeonteueul. Longitudinal channels extending along the concave surface. At least one mechanical fastener is operative to connect detachably coupled with the segment of the pair. The elastic annular seal is located in a longitudinal channel of each segment. Branching device connects the branch pipe through the orifice in the main pipe using a saddle-type seal on the main pipe.
