  • Ferrous | Rolling (Metalworking) | Galvanization

    Sizing mills have 2 10 stands, and can have two or three rolls per stand. As the circumference is reduced, the wall thickness is increased. In stretch reducing mills, which normally have three rolls per stand, and up to 30 stands, an increase of wall thickness is avoided, as tensile forces are applied between the stands during the process.

  • Think piston accumulators for wind turbines

    Oct 06, 2010 · These differ for piston and bladder accumulators. In a bladder accumulator, the compression ratio can be no greater than 4:1. In a piston accumulator it can be 10:1 or greater as long as the design pressure is not exceeded. The difference is that beyond a 4:1 ratio, the bladder can be crushed by hydraulic fluid pressure to the point of damage.
