Non-Destructive Controls on Steel Wire Rope and Lifting Accessories

SIRTEF has got inside personnel qualified by the CICPND and certified at the 2nd level to make Non-Destructive Controls on steel wire ropes, slings and lifting accessories with the following methods:

Penetrating Liquids

This kind of control is carried out to highlight defects on surfaces of any kind of material (castings, welding, pipes, etc.). The non-destructive test method with penetrating liquids is based on visual examination of the surface after the application, in sequence, of a penetrating product and a detector one.

The method makes all discontinuities visible on the surface as they normally are not visible or are hardly visible to the naked eye instead. Here below technical details:

• Controllable surfaces:
  Actually, all non-porous surfaces, areas without grooves or areas able to absorb penetrating liquids.
• Detectable Defects:
  Surface defects such as cracks, porosity, folds and incisions
• Functionality:
  Easy to use – applicable on site - sensitive to even apparently un-significant defects
• Application:
  Surface controls on non-porous materials

Magneto-scope Control

This kind of control is based on the deviation the magnetic field lines, as being induced in a ferromagnetic material, undergo at the presence of some discontinuity.
It is used in the control of welding, castings, etc.

Here below the technical details:

• Detectable Features:
  Magnetic flow dispersed due to superficial or sub-superficial discontinuities such as: cracks, cavities and inclusions
• Functionality:
  Sensitive to both surface and sub-surface defects
• Application:
  Surface and sub-surface controls on all ferromagnetic materials
