When welding thin st/st (generally 304/316) tube we have traditionally TIG welded outside using a purge gas on the inside of the tube, but have previously tacked the assembly for trial fits without purge gasses.
A client has suggested that we should purge all tack welds as the oxide layer...
We have a vessel that is heated with steam in an atmospheric jacket.
The steam is thus at atmospheric pressure. The bulk water inside the vessel is at approx 35C and static. How can I calculate the mean temperature of the material of the vessel shell (in this case stainless steel).
I...
I am thinking of converting a Honda Blackbird engined race car to run on Bio-ethanol as I've heard that reasonable power increases can be attained without mechanical changes. Has anyone got any views / advice? in particular what CO figures should be achieved or is there an alternative to use...
Does anyone have any figures for the latent heat capacity of cream as it cools and the various fats solidify?
I'm aware that there is an effect both as cream is initially cooled and as it is aged, and that the actual make up of creams can differ, but can anyone point me towards a source of...
We are trying to feed granulated sugar from a hopper into preheated water to make a sugar syrup. The system works fine, but the steam rises from the water and dampens the sugar in the hopper causing blockages. We control sugar dropping with a rotary valve which has an air ring below (compressed...
Has anyone had any experience of de-odourising vessels or similar in the dairy industry? in particular looking for info on vacuum sizing and flow for a cream feed deaeration vessel.
Looking for formulii / rules of thumb, but current application has cream feed rate of 6000 lph at 85 C.
