    Operator Rounds

    They would need to be Class 1 Div 2 rated which would drive up the price very fast I am sure. Sorry I keep adding constraints.

    Operator Rounds

    Temperatures are around orifices and coolers on API flush plans to check that the seal is getting flushed properly. For example on a plan 11 flush an operator should check the temperature on the upstream and downstream side of the orifice if they vary significantly the orifice is clogged and...

    Operator Rounds

    Yes we did have that issue initally but have corrected it. Our primary issue now is picking up things in the background when trying to measure tubing / small bore piping due to the area the IR gun measures. This can be corrected by holding paper or a glove behind what you are measuring and...

If so how was the program run? and what equipment did you use to gather data? The refinery I work at has...

    Percent off Pump Curve

    Itdepends: I do not think dead heading this pump is an option from a process standpoint but I will confirm. However how would a restriction in the suction or discharge lines affect pump performance in relation to the the curve? My pressure gauges are right at the suction and discharge nozzles...

    Percent off Pump Curve

    Is there a standard method for calculating the percent off a pump curve for pump which has degraded performance over time (wear rings, impeller wear, any other reason really)? The way I see it there are two possible methods but maybe there is additional methods I am unaware of. The two I can...
