Method Statement For Installation T&C of Chemical Fire Suppression System

Fire Suppression System Installation Procedure
Piping Work

  • Use schedule 40 pipes with 3000 PSI fittings. Install pipe and fitting in strict accordance with the approved drawing.
  • Piping between cylinder and nozzles must be through shortest route possible.
  • Any deviation in the routing or number of fittings must be approved by the Design Engineer prior to the installation.
  • All piping shall be earth bonded. Piping must be reamed free of burrs and ridges after cutting or threading.
  • Teflon tape only need to be applied on pipe joints. Tape should be applied on male thread only.
  • All pipe hangers must conform to general industry standard.
  • For reducing pipe size use only concentric bell reducers.
  • Before fixing discharge nozzles blow the system piping free of debris.
  • Install nozzles, ensure that correct nozzles types part numbers and orifice sizes are installed in the proper locations.
  • Ensure piping and nozzles do not interface with objects in the hazard area.
  • Install SINORIX1230 cylinder at the location shown in the drawing observing the safety requirements while handling the SINORIX1230 cylinder.
  • Secure the cylinder to a solid structure.
  • Connect the pipe system to the cylinder.

Installation of Fire Detection System

  • Arrange detection system material inspection and obtain necessary approval.
  • Install the control panel and devices as per the approved drawing layout.
  • Test the cabling for open, short circuits prior to connecting to devices.
  • Terminate the cabling and conduct pre commissioning tests on the system.
