Hi,
There is an area where we would like to install a number of steel vessels, supported off legs, for storing liquids. Some core sampling was carried out last week (attached a couple of photos) and we managed to get a measurement of the slab thickness in a couple of different locations. It is...
Hi,
The plant I am working in has experienced some very rapid and localised corrosion on 316 stainless steel process pipework. It is almost entirely around the heat affected zone. See attached document showing some photographs of this. The duty is a clean in place return line. To mitigate the...
Hi,
We're running a duty/standby hot water (180oF) centrifugal pump arrangement on our plant hot water ring main. A mechanical seal failure occurred over the weekend on one of the pumps.
The seal faces are silicone carbide. The pumps have been running for less than 6 months continuously. I am...
Hi,
We're running a hot water ring main and have experienced some issues with pressure spikes bursting gaskets on a plate and frame heat exchanger.
Water is pumped from a 20,000L tank via. centrifugal pumps that are powered by variable speed drives. There is a 100m pipe run before the water...
Hi,
I've two jacketed pressure vessels which are serviced by both cooling water and low pressure steam. There is a compressed air blowdown inbetween cooling/heating duties.
I need to be able to eliminate air from the jacket when heating and cooling.
At the moment there is a thermostatic air...
Hi, I'm having some issues with a centrifugal pump which is being used on a CIP tank.
Pump is 18.5 kW and is on a frequency inverter drive.
Tank capacity is 2,500L
Pump suction pipework diameter is 3" NB
Pump suction pipework length is ~ 1m
There is a full bore ball valve in the suction line...
Hi,
I am installing a hot water ring main to serve a number of end users in a factory. The main is fed via. a 20 m3 buffer tank with a centrifugal pump on an inverter drive, it returns back to the same tank.
The average demand I have calculated will be 15 m3/h.
The pump will be spec'd to...
Hi from a long time lurker and first time poster,
I am attempting to size a pipe for a shear thinning, non-newtonian fluid. I have some rheology data which I have attached to the post.
The required flow rate through the pipe is 6 m3/hr. The pipe length is approximately 60 meters.
I regularly...
