5 key points for choosing nozzle material


① Fluid and temperature of environment

  PVC: Less than or equal to 40°

  UPVCLess than or equal to 50°

  PPLess than or equal to 60°

  PVDFLess than or equal to 70°

  PEEKLess than or equal to 260°

  Stainless steelLess than or equal to 400°

  HastelloyLess than or equal to 400°                                                         

 

 

 

 

② Chemical resistance

 

  Stainless steel is not able to be resistant to chemicals.
