For liquid with different specific gravity, multiply capacity of pipes by specific gravity, and add weight of pipes to it. & Use flow rate of 1m/sec for calculating flow rate and velocity in pipes and diameter of pipes. Ex.) For flow velocity when using 2S pipe at 10m3/h: V (Velocity of Flowing Fluid) =10(m3/h)/6.46[(m3/h)/(1m/sec)]=1.55m/sec 2 3FDPNNFOEFE 5JHIUFOJOH 5PSRVF BOE *ODPNQBUJCMF .PVOUJOH .FUIPE Tightening torque for 1S ~ 3S should be 3N t m, and for 8A ~ 15A should be 3N t m or more. Further tightening or loading of pipes may deform the gaskets and cause liquid slug, leakages and damages. When fluid leaks during use, retighten pipes with torque above. If this fails to stop leakage, replace gaskets. *ODPNQBUJCMF .PVOUJOH .FUIPET 1) Pipes are not aligned. 2) Pipes are not horizontally aligned. 3) There is too much clearance between pipe fittings.
