  • The simple process of the stainless-steel pipe and crimp-fitting design is:
  •  
  • - Tubing, or cut tubing is to be deburred internally and externally prior to inserting into the fitting.
  •  
  • - Ensure the O rings are in place in the fittings.
  •  
  • - Tubes are to be externally marked at the face of the fitting prior to assembly to ensure full insertion and proper crimping to ensure a leak free joint.
  •  
  • - Crimping tools used are to be electrically-driven hydraulic operation, and in accordance with fitting manufacturers standards and specifications.
  •  
  • - Provision is to be made for purchase of crimping tools in your tender.
  •  
  • - No use of solvents or oils are to be used on O rings during assembly of piping and fittings. Only soapy water.
  •  
  • - Pipe assembly to be loosely supported prior to crimping to ensure the correct alignment is achieved.
  •  
  • - After crimping, perform a visual inspection that the crimp has been executed correctly.
