Tubing and rods inspection


Inspection, washing and reconditioning of casing, tubing and rods by Non Destructive Testing methods and the newest technologies in washing systems. Certification and selection according to the pre-established acceptance-rejection criteria.


Most common causes of pipe and sucker rod failures

  • Insufficient inspection of the tube body and thread.

  • Damages during handling and / or transport.

  • Bad practice in lowering the well pipes.

  • Corrosion in the internal and external part of the pipe due to the presence of corrosive fluids.

  • Design and operation failures.

  • Failures in connections and couplings.

  • Rod failures due to deflection and surface damage.

  • Lack of traceability of each piece, identification and improvement of the process.

  • Lack of availability of rods and pipes at the wellhead.


Implementation of Non-Conventional NDT techniques, computerized maintenance management and the washing and recovery process

  • Washing of Tubing and Rods prior to inspection.

  • Visual inspection of the body and ends.

  • Inspection of the pipe body with electromagnetic and UT technique.

  • Placement of couplings with the adequate torque in tubing and rods.

  • Inspection of threads with magnetic particles and Induced Currents.

  • Calibration of the internal diameter of the tube body with Drift Mandrel.

  • Classification of the material according to the grade.

  • Separation and stowage of tubular material and rods.

  • SIGMA (Comprehensive Asset Maintenance Management System).


The final report includes a detailed list of all the tubes, identifying the location of all the flaws detected in the length of the tube.

The list has an easy filtering system that allows you to access the results of each of the tubes, quickly and easily.
