    Derating of centrifugal slurry pumps

    55% (by mass) slurry with solids sg of 3 and fluid sg of 1.2 (overall density of 1800 kg/m3). In determining the ER and HR using the Warman catalogue, can the value of S (solids sg) be reduced by 3/1.2 to reduce the effect of ER / HR?

    Instrument Bypass Line

    We are considering using a 80NB bypass line off a 400NB to install a conductivity probe. The bypass line will have isolation valves and enable on-line maintenance to the probe. In theory there should be flow, however the concern is that fluid dynamics at the bypass may prohibit flow through the...

    Pressure Vessel Relief Valve - Interpretation of the codes

    The codes (AS1210 and ASME) call for RVs to protect the vessel. I am looking at a Condensate Receiver which would normally receive about 500 tph of condensate. In the extreme case, if a number of things all went wrong at the same time the flow can go up to 1500 tph. The design therefore has to...
