    Software to track boiler watertube repairs, replacements, inspections, etc

    Do any of you know of a software where you can model some kind of 3D model of a watertube boiler and track repairs, replacements, inspections, etc that are made? Currently doing this with spreadsheets and looking for a better option. Thanks

    CO2 regulator freezeup

    Sulfuric Acid Piping Slope

    Thanks for the info. What I am looking for is to slope the pipe so it drains back to the tank. For a water line, you would normally look at 1/4" per 1'. I was wondering if there is an acid equivalent. Thanks.

    VFD vs. Head Tank for Constant Pressure

    Hi Keith, Thanks for your answer! By head tank, I mean large elevated tanks where the water is pumped to create constant pressure. They are normally used on industrial sites such as mines.

    Hi LittleInch, I am well aware that the pipeline needs to be made safe prior to work. What I am really trying to determine is if someone more knowledgable then I can suggest a better method then purging with water before we go ahead with it. The real problem is the pipeline location, making...

    Pipeline purge prior to work

    Greetings all, I have a quick question about pipeline repair procedures. We will be cutting out some pipeline sections to replace them. What is the normal work procedure? Obviously, the sections will be drained of fluid but is a total purge also necessary? The operator suggests that the...
