We use our Armor Plate System made of composite materials - no need to weld or cut pipes.
Pittings of localized corrosion in gas and oil pipelines in operation can be permanently repaired and at the same time provide anticorrosive protection to stop the advance of said focused corrosion, with the Armor Plate System.

CIS / DCVG

The CIS technique is an inspection system developed for the detailed analysis of the cathodic protection levels in underground pipes. The technique consists of the continuous measurement of the pipeline potentials with respect to the copper / copper sulfate reference electrode.
The operator makes a tour of the pipeline by extending a fine-gauge wire, the operator advances on the pipe and the field computer records the values of the potentials.

DCVG's technique, “Direct Current Voltage Gradient” is a system developed for the detection and analysis of defects in the lining of underground pipes. The faults are located by examining the potential gradients in the ground, covering the pipes to determine the direction of the flow of the cathodic protection currents. Since cathodic protection acts in a current flow to exposed steel points in the pipe, defects in the coating can be individually located.

CIS - DCVG Inspections

We offer services to evaluate the integrity of gas and oil pipelines called EDCA Services, including the precise weighting of defects in the coating and corrosive activity, using a fast and efficient integrated CIS / DCVG technique, avoiding having to interrupt the inspection and return to the site. of the defect later.

External Corrosion Direct Assessment (ECDA)is a structured process used to assess the integrity of buried rail pipe. ECDA's goal is to enhance safety by managing the risk of pipeline corrosion failure while minimizing the cost required for excavations and repairs. ECDA can also be used where other methods such as on-line inspection (ILI) and pressure testing are not possible or practical. The practice recommended by the NACE Standard on Methodology for the Direct Assessment of External Corrosion of Piping (RP0502-2002) describes ECDA processes such that "... allow the prediction of susceptible areas where corrosion activity has given, is happening or can happen ... "

The application of ECDA to achieve reliable and meaningful results requires appropriate field equipment and experienced personnel to collect, record and analyze the collected data.
Our professional and field staff are experienced in ECDA inspections. We are provided with the equipment for the studies and data collection. The data is analyzed by professional engineers with many years of experience in pipeline corrosion prevention.

ECDA is a four-step process: 1) Pre-assessment; 2) Indirect inspection; 3) Direct examination; 4) Final evaluation. Below we explain the content of the steps by way of introduction:
1) Pre-assessment collects and evaluates the history and characteristics of the pipeline. Based on the information collected, the feasibility of applying ECDA is determined. When feasibility is established, the pipeline is divided into regions with similar exposure and where the same indirect inspection tools can be used.
2) Indirect inspection uses a combination of 2 or more field inspection techniques such as CIS, ACVG, DCVG, AC attenuation, etc., to identify areas with corrosion activities or coating failures. Data is evaluated and high risk areas are identified by systematic excavation analysis. con actividades de corrosión o las fallas de recubrimiento. Los datos se evalúan y se identifican las áreas de alto riesgo por el análisis sistemático por excavación.
3) Direct examination involves the selection of excavation sites and the physical identification of defects for later action such as repairs or replacement.
4) Post-assessment evaluates the 3 previous steps of the ECDA process and establishes the future evaluation schedule.

We have developed an integrated indirect inspection technique that links CIPS and DCVG measurements. This integrated technique allows acquisition of CIPS and DCVG data simultaneously. Higher efficacy and lower study costs are achieved by combining both techniques.
