This TIP intends to provide guidelines that may be used to increase the maximum allowable working pressure of American Society of Mechanical Engineers (ASME) certified cast iron paper machine dryers. This process, in which no physical change is made to the dryers, is defined as an “alteration” by the National Board Inspection Code. Machine capacity may be increased by increasing dryer steam pressure. This benefit may be accompanied by an increase in machine speed.
