I am trying to determine the most appropriate (and cost effective) insulation covers for piping and vessels containing sodium hydroxide in concentrations ranging from 25% to 50% and temperatures from 100F to 350F. Aluminum is not appropriate because the NaOH will dissolve it if it leaks, and...
Thanks for the response. A control valve on the air bleed line with a PIC loop on the pump suction is the approach I have used previously. The issue has been with getting the correct amount of air into the suction to allow the control valve to be put in automatic so it will adjust within a...
I am trying to find the correct method for determining how much air should be added to the suction of a vacuum pump to control the suction pressure at a specified value within the design range of the vacuum pump. My previous attempts at determining the air flow have not been accurate enough, so...
Does anyone know of a vendor that can supply an 8" diameter Kynar-lined bent pipe section with two approximately 20 degree bends in it? The overall length is about 5 feet. I've only been able to locate suppliers of this type of pipe who can produce a maximum 4" diameter bent pipe.
I need to purchase some thermowells and pressure instrument diaphragms for pipe which has a saturated brine solution at 280 degF that is about 25 wt% NaCl? Any concerns with long-term corrosion issues if I use Hastelloy C material? Would titanium be a better choice than Hastelloy C? Where can...
Working on an application to supply toilet/sink wastes from a remote part of a plant to a pressurized sewer. Have been told that the pressure in the system is 35 psig. This is a small daily volume, probably 200 gallons per day. Sewer line is up in a pipe rack. My inclination is that a wet well...
