Are you hoping to generate flash steam from the process water, in which case this is viable, but you won't get loads of flash as you are only flashing down by 5 bar - but you will get something. You will also have water still at 20 bar and saturation temperature that you could get energy out of...
Hi,
I'm looking for a supplier for a DN500 globe stop valve, ANSI 600, for use on steam. Can anyone suggest a supplier that they have good experience of?

Gladdkenn,
The conductivity level is dependant on temperature and pH. Usually the sample is cooled through a sample cooler when taking samples (otherwise you risk some of the water flashing off and concentrating the TDS level in the water). You can either not bother to nutralise the sample and...
Hi,
I have been asked about the need for dielectric unions in steam and condensate systems when using a combination of steel pipes and SG iron and bronze valves. Can anyone give me advice on whether they are needed? Just so you know, the job involves hot water generation in hospitals.

I have been asked to select a steam trap for installation after a desuperheater. I have been led to believe that it is usual to install a collecting pocket with a trap in such circumstances. I believe the desuperheater will be a spray type.
What load do you base the sizing of the trap on? The...
I have been asked for help regarding the requirements for pressure testing new steam pipe installations. This is not my field of expertise and it is not my intention to start advising on a subject I know little about. But can someone point me in the direction of a standard that I can refer them...
Can anyone point me in the direction of some information regarding the use of superheated steam in heat exchangers. I know that it reduces the heat transfer rate as the bulk of the heat transfer is obtained by the change of phase, which only occurs after the steam has lost its superheat.
I do...
I belive you can use an oil in water turbidity meter. A standard turbidity meter will not do as it will only pick up solid particles, so be careful when contacting suppliers. Try the usual analytical instrumentation suppliers.

From what I have been led to believe, the vortex type of separator will give the better performance if the conditons are ideal (for the separator). Baffle type separators are better where the pressure and flow rate fluctuate. Personally, I prefer to specify baffle type units.
It is important...
pclegg25,
I would recommend the courses that Lancaster University run. I completed their Certificate course a year ago. This course is a 9 month course based on modules completed on campus along with written assignments. The course covers all aspects of project management and is applicable no...
I am not just on about any old 3 way valve. I am aware of the 3% rule.
I am aware of two companyies that offer such valves. Leser and Spirax Sarco. The manufacturers can double check that the changeover valve they offer complies with the 3% pressure drop requirement. Take a look at these...
It seems to me that there has been a lengthy discussion on the issue of 3 port valves for this application. As I origianlly suggested, a changeover valve, which is a type of 3 port valve specially designed for this purpose, would do the job. No need for keys, interlocks, mechanical linkages, or...
rdj123,
I guess that you are only after a PN16 valve if you want cast iron. I work in the steam business, so I know that Spirax Sarco do a range of bellows sealed stop valves.
