Fire Tee Repair Clamp Application in Industrial Plant Fire Protection Pipeline

Fire protection pipelines inside industrial factories have more severe operating conditions than ordinary commercial buildings.Production equipment generates continuous mechanical vibration and transmits vibration force to fire water pipelines.Tee joints are typical stress concentration points and are more prone to fatigue cracks and corrosion perforation.Workshop atmosphere may contain oil mist,chemical vapour and high temperature radiation,putting higher requirements on the mechanical strength and corrosion resistance of repair clamps.

Heavy duty fire tee repair clamps adopt thicker metal shell and high strength bolts.The sealing gasket uses oil resistant and high temperature resistant elastomer formula.These clamps are suitable for fire mains laid on pipe racks in petrochemical,power and manufacturing plants.During installation on industrial pipe racks,operators need to keep the clamp assembly away from high temperature equipment surfaces and check the stability of adjacent pipe supports.

The repair process does not require large disassembly of pipe rack structures,reducing production interruption.After repair,regular overhaul together with fire pumps and valves is necessary.Inspection items include clamp shell corrosion,bolt tightness and gasket ageing.Reliable sealing of tee joints ensures industrial fire water network can maintain stable pressure and provide fire fighting water when fire accidents happen in production zones.
