    pump alignment

    I assume you are talking about coupling alignment. We run hot oil pumps at 540 deg F. I use magnadrive coupling, which is aligned only with a straight edge. Since there is an air gap, no misalignment load is transferred to pump shaft/bearings/seal. Wonderful for extending life of these...

    VARIABLE RATIO TRANSMISSIONS

    Try MagnaDrive Corp, How about permanent magnets with an adjustable gap allowing a turn down ratio of 100%!! feedback loop to allow any set point or constantly variable speed you want. Built in soft start capability. It is variable gap between permanent magnets and copper plate. Magnet...

    A106 sched 40 hot oil steel pipe potential for warping.

    Thanks for the suggestion metalguy, Here is scenario. This 3 inch Sch 40 pipe sitting in mill (ambient air about 100 deg F) with hot oil flowing thru it. Suddenly hit with 2 in fire hose, water at about 80 deg F. So, in probably a fraction of a second the surface temp on one side is reduced...

    A106 sched 40 hot oil steel pipe potential for warping.

    Thank you Stanweld for the response. If I understand your comment, it would be possible to have some "mild warpage" even after the temp difference from one side of pipe to the other is no loger there? In this case the pipe is vertical, about 15 ft long and supported only at bottom...

    A106 sched 40 hot oil steel pipe potential for warping.

    Adding to my thread, If water is sprayed on one side of a hot pipe it will obviously curve in the direction of side that was cooled. The question is at these relatively low temperatures, will any of the curvature be retained once the steel pipe temp is back in equilibrium? I suspect not, but...

    A106 sched 40 hot oil steel pipe potential for warping.

    These 3 inch pipes (not insulated) supply hot oil to each press platten. oil temp is 410 deg F. These secondary loops have constant oil circulation. If sprayed with fire hose (2 inch) with ambient temp water is there any chance of pipe warpage? This press has 16 plattens 8 ft by 16 ft and...
