    Data Validation

    Hello Everyone, I am fairly new to using drop down menus in Excel, but I have managed to get a few working and have them linked so the drop down menu is dependent on an initial selection. For example, you can see the webpage here I am using to make the conditional lists.... ->...

    Hello Everyone, I had a recent assignment where we were looking at installing pumpable insulation into a casing due to hot spots. We were looking at Kaowool type HS pumpable. The product spec sheet recommends installation with an extrusion pump. Our vendor offers these pumps for rent, but...

    Hello Everyone, I hope you are all doing well. I have a question about job search ethics that I do not remember being brought up before and I didn't have much luck with the search. I am a field service engineer with an OEM manufacturer. The work is great, I have learnt a lot, but I got...

    Turned Charts Off

    Hello Everyone, I have accidentally done something I've never done before in Excel. I've turned off all my charts in a workbook. I still have all my data, but I cannot insert a chart. The icons on the ribbon for charts and illustrations are not active. Does anyone know how I did this?

    Orifice Flange Tap Routing and Orientation

    Hello Everyone, I've done a search of the internet and this site regarding the routing of the piping to flange taps around an orifice plate. I've found a number of references to the orientation of the taps on the flange, but I'm looking for information on routing of the piping from the ports...

    Flushing Connection

    We have a customer who is looking to flush their system before any of the external piping is complete as part of their pre-commissioning. We consider our flushes to be high flow, low pressure relatively speaking(150usgpm, 100psi for example). We are rarely on-site during the flush, and even...

    Set Point Line

    Hello Everyone, I make a lot of scatter graphs where I compare temperatures to their setpoints using Excel. I'm wondering if there is a way to mark the set point on the graph as an option? What I've been doing is either drawing a line or adding a set point temperature column in my data. I...

    Dinosaurs

    As usual, I wasn't really sure which thread to put this in, but I decided on this thread... How do you manage your spreadsheets with respect to your work? I find sheets to be a personal thing. My boss seems to want to force everyone to use his old, outdated, ugly spreadsheets. They drive me...

    PID - the D

    Hello Everyone, I have a general question regarding PIDs that I hope is easy to answer. I've done a search of this forum and I'm not sure I've seen the answer, but if I have, I didn't understand it or missed it. In PID controllers, the D is the derivative term. I saw somewhere it described...

    Temp. Transmitter Head Residue

    Hello All, I'm not 100% sure this is the right forum to post this, but it seems like the best place to start. I'm on-site commissioning a boiler and I have a number of thermocouples/transmitters throughout the unit and piping. Two of these are installed on the bottom of two different outlet...

    Alternative for Flushing Pipes

    Hi Everyone, I've been asked to look into the process of "Froth Flushing" by my PM. I've started a web search and, so far, most of the websites I've been to have the exact same information. Even the wording is almost identical. I'd be interested to hear any comments from any exposure any...

    Xsteam

    Does anyone have any experience getting Xsteam to work in their own Excel worksheets? The program works great for me as a separate file, but I cannot figure out how to use it within my own files. I'm sure there is a way but I cannot get it to work. As always, any help is appreciated.

    Cell Highlighting

    Hi everyone, I'm having an issue with Excel 2007 that has been bothering me for sometime. I've spent sometime looking online for a solution but haven't had any luck. My problem is when I highlight cells in Excel the colour that the cells are highlighted in is a very light grey and it's hard...

    Cooling Tower Make-up Pumps

    I'm having an issue at my plant with our cooling tower's make-up water pumps. What we're seeing is our cooling tower calls for make-up water, solenoids valves open downstream of the pump, five seconds later our make-up pump turns on, and then instead of pushing water up to the tower, the pump...

    I'd appreciate some help trying to figure out something I've seen in our plant that I have not been able to explain. We are a district energy plant and have several remote stations. Our system is closed loop. What I've noticed is the pressure on the return line from each of the stations is...

    Welding Requirements

    I work in Canada on hot water systems. These systems are all indoors and isolated from the outdoor conditions. The pipework is also easily accessible throughout the lifetime of the units (well they're supposed to be). A few people have told me lately that our welding procedures are extremely...
