Cylinders legalization and repair:


Cylinders are certified in the presence of an UDT inspector (Office of Technical Inspection); the process consists of the below listed stages:
  • visual inspection of a cylinder
  • weighing the cylinder zbiornika (to check for loss of cylinder weight) 
  • pressure test (checking the cylinder for leaks and strength by means of a water pressure test in a closed circuit) 
  • cylinder painting 
  • changing the cylinder marking (by stamping the marking and the date of the next cylinder certification)

Hire of:
