    pickling pipe

    I need some direction from some of you experts. I'm currently trying to start a new hydraulic system-piping is all carbon steel-contractors installed the piping, it was hydro-tested, chemically flushed, pickled, supposedly neutralized and then contractors went to an oil flush and had to meet a...

    metric pipe chart

    Can someone direct me to a website that has a metric pipe chart with wall thickness, working pressure and burst pressure ratings. Didn't come up with much when I searched on the "net". Thanks, Tom

    annual cost of electric motor

    I'm trying to justify energy savings on an electric motor that runs 3 hydraulic pumps. The motor is 125 hp, 480 VAC and amp load will vary according to how many of the pumps are loaded ( amp draw is approx. 50 amps with no pumps loaded and increases to approx 140 as work is done)probably...

    VFD with hydraulic pump??

    How much energy savings, if any can be derived from replacing a 40 hp 1200 rpm motor with a VFD motor-this is to run a hydraulic pump-system pressure is 2000 PSI and most of the time only about 15-18 gpm makeup fluid is needed. The original system keeps the 1200 rpm constant and loads/unloads...

    piping failure

    Is there a direct connection relating pipe failure(esp. welds in carbon)to increase in temperature. I thought I had read a thread about this on one of the forums-I've searched for it and have either missed it or dreamed the whole thing up. I work in a large minimill and our glycol comsumption...

    drain lines termination above/below fluid level

    This subject generated a lot of interest on IFPS board. I'm interested in any input from this group of professionals. Several posters were pro above the fluid level-several including myself were pro below minimum fluid level. The discussion started specifically about drain lines for valves...
