  • The High Pressure Torsion (HPT) Process :: Total Materia

    The high pressure torsion process compacts the material under very high pressure between two plungers producing a very specific material microstructure Ultrafine grained materials offer substantial advantage over coarser grained materials displaying higher strength and better ductility Among the SPD techniques, HPT process is one of the most powerful techniques to prepare ultrafinegrained

  • What is the difference between a High and Low Pressure

    A Low Pressure Ball Float Valve is provided with a larger hole within the valve assembly (looking down inside the threaded end) to fill the tank or cistern up more quickly, however if the water pressure is too high this will result in excessive noise or water hammer Conversely if a high pressure ballcock valve or insert (with small hole) is used the cistern (or tank) will take a long time to
