PT – PENETRATION TESTING

Penetration method is one of the non destructive testing techniques. Its used for detection of surface defects in both ferromagnetic and light alloys as well as austenitic steel. The limitation comes with porous materials and with complex shapes. PT is based on chemicals penetrating the discontinuities due to phenomenon of capilarity, Then the developer is getting into reaction with the penetrant chemicals and thus making the defect indication visible to human eye. Penetration testing can be done both during the production processm and after the part or product has been already in use, for diagnostic purposes. PT can be done manually or with an automated system. Depending on type of observation, the testing can be done in white light (artificatial or natural), or UV light. There are many different solutions for PT method.

APPLICATIONS OF PENETRATION TESTING

PT allows for detection of discontinuities in parts. This inspection method can also be used to test ceramics and plastic alloys. Penetration testing can detect defects such as discontinuities, cavities, leakiness, deep gashes, narrow and wide cracks, microfractures and surface porosities.
In serial production, the penetration testing is done on FPI lines.

ADVANTAGES OF PENETRATION TESTING

  • quick and easy inspection
  • high success rate of defect detection
  • low inspection cost
  • possibility of process automation (FPI lines)

DISADVANTAGES OF PENETRATION TESTING

  • high difficulty of porous surface inspection
  • detection of only open defects
  • cleaning and defreasing of inspected surface (dirty method)

PRODUCERS OF EQUIPMENT AND SYSTEMS FOR PT

Regarding PT method we produce the highest quality of equipment, but we also cooperate with other companies:

Our company has started the production of FPI lines in 2015 and we currently offer:

  • compact workstations
  • manual/semi-automatic/automatic lines
  • degreasing lines with manual or automated handling of elements – ultrasonic washers, jet washers
  • transport systems for specific technological requirements – manipulators, roller systems, gantry systems
  • waste water threatment systems

Chemetall Polska specializes in delivery of chemical compounds for surface processing.
Due to our cooperation we can offer chemicals for:

  • washing and degreasing of the surface
  • process of steel, zinc, or aluminum surface preparation
  • copper and brass surface coating of wires
  • ductile processing of metals
  • metal sheet processing
  • temporary corrosion protection
  • removal of paint coatings
  • forming, embossing and oiling
  • aluminum element processing before painting

WHY ITS WORTH IT TO CHOOSE CASP SYSTEM AS SUPPLIER OF DEVICES AND EQUIPMENT FOR PENETRATION TESTING

Casp System has an extensive offer of chemicals (penetrants), accessories, surface preparation lines and FPI lines for penetration testing. The offered technological lines for penetration testing allow for quick detection and identification of surface defects. Using the FPI lines enables verification of non porous materials made out of different materials (such as aluminum, magnesium, copper, titan, steel, brass, ceramics, plastics, glass and cast materials, for the purpose of detection of defects that can result in problems. We offer automated penetration testing that has wide use in aviation and car industries.

We can assure You that all FPI lines delivered by Casp System are made to last, with good quality and verified components, so that You, the customer, can use them for many, many years. In order for the penetration testing to be accurate, its neccessery to first make sure the surface is in proper condition. For this to be possible, we offer comprehensive solutions including ultrasonic washers that utilize the appropriate chemicals, but with lower concetration then in conventional methods. The advantage of those washers is their efficiency. The unit is effectively removing any contaminants, leaving the surface clear and ready for inspection. During usage, all the indicators, meters, and regulators that the FPI lines are equipped with allow for constant control of the state of the process every step of the way. Due to our care for the environment, we offer optionalally, filtration systems that allow for using the same water more then once in the process.
