Fabric Selection for Diaphragm

Fabric Selection for Diaphragm

A key component of Diaphragms is the fabric reinforcement selected to ensure the diaphragm will withstand the application pressure and cycle life expectations 

Diatax has developed a comprehensive selection of standard fabric styles, each with specific physical characteristics that are selected based on weave patterns, tensile strength, form-ability and chemical and heat resistance capabilities, as well as other variables.

When selecting the fabric to be used to reinforce the diaphragm, the following factors are important:

  • Diaphragm pulse rate effect
  • Risk of tearing of the fabric due to flange sealing conditions
  • Required balance between sensitivity and strength of the fabric
  • Environmental effects on the fabric, i.e. flammability and temperature
