Refuerzo de matriz compuesta para la reparación de un ducto que transporta GLP
PRESENTACIÓN DEL CASO:
Una importante empresa de distribución de GLP ubicada en Lima, Perú, detectó que un ducto de una de sus líneas de distribución presentaba daños en su estructura externa causados por corrosión atmosférica.
La tubería de 12”, que opera con una presión de 150 psi, presentaba una falla de 55 cm de largo y una profundidad de 4 mm.

SOLUCIÓN
La solución propuesta por Morken no solo contempló reparar el daño detectado, sino también dotar al mismo de la protección anticorrosiva que le permitiera seguir operando por al menos 20 años más.
A tal fin, Morken reparó la zona dañada con un sistema de matriz compuesta basado en una combinación de fibra de carbono y materiales epóxicos que combinados le otorgan estabilidad mecánica a la tubería y aseguran la integridad del ducto.
El servicio fue ejecutado por un ingeniero certificado en reparaciones de matriz compuesta, en tan solo 45 minutos.
RESULTADOS Y BENEFICIOS:
Se solucionó rápidamente el riesgo operativo planteado por el cliente, reforzando el ducto en la zona dañada.
Las tareas se realizaron en un muy breve período de tiempo, sin registrar ningún inconveniente y con la tubería en operación, con el consiguiente ahorro de tiempo y dinero para el cliente.
Se evitaron posibles daños tanto físicos como a las instalaciones debido a la naturaleza del fluido transportado, al no ser necesario realizar trabajos de soldaduras.
La solución provista por Morken permitió extender la vida útil del ducto por al menos 20 años.
Reinforced composite matrix for the repair of a pipeline that transports LPG
Presentation of the case
A major LPG distribution company located in Lima, Peru, detected that a pipeline of one of its distribution lines had damage to its external structure caused by atmospheric corrosion. The 12 “pipeline, which operates at a pressure of 150 psi, had a failure of 55 cm long and a depth of 4 mm.

Solution
The solution proposed by Morken not only contemplated repairing the damage detected, but also giving it the anticorrosive protection that would allow it to continue operating for at least 20 more years.
To this end, Morken repaired the damaged area with a composite matrix system based on a combination of carbon fiber and epoxy materials that combined to give mechanical stability to the pipeline and ensure the integrity of the pipeline.
The service was executed by a certified engineer in composite matrix repairs, in just 45 minutes.
Results and benefits:
The operational risk posed by the client was solved quickly, reinforcing the pipeline in the damaged area.
The tasks were carried out in a very short period of time, without registering any inconvenience and with the pipeline in operation, with the consequent saving of time and money for the client.
Possible physical and facility damage was avoided due to the nature of the fluid transported, as welding work was not necessary.
The solution provided by Morken allowed to extend the useful life of the pipeline for at least 20 years.
SERVICE OF CALIBRATION AND MECHANICAL CLEANING OF A MINING AQUEDUCT
Presentation of the case
An important mining company in Chile detected the need to clean and calibrate a pipeline that transports water for the operations of the mine.
Being a strategic resource for the normal development of mining operations, it was vital to carry out tasks safely and efficiently.
By means of a field inspection, Morken engineers verified that the aqueduct has an important operational complexity since it is not possible to consecutively launch the two tools (cleaning and calibration).

Solution
Taking into account the characteristics of the duct, Morken engineers devised a PIG tool with two bodies linked by a cardan joint where, in the first body, metal brushes were mounted for internal cleaning and, in the second body, they were installed the calibration plates with a ring of magnets.
The entire service included the following scope:
- Internal cleaning by heavy drag using metal brushes with magnetos collection.
- Calibration of the duct through passage of Caliber Plate.
- Follow-up with state-of-the-art equipment: geophone, transmitter and electromagnetic detector.
- Analysis of the gauge plate for minimum step determination.
- Advice on cleaning and integrity of pipelines.
Results and benefits:
The cleaning of the aqueduct was carried out by dragging sediments and magnetizing metal elements that were trapped by the second body of the PIG. With this, fluid transport was improved by decreasing the loss of charge in the pipeline caused by the sediments.
Obstructions, ovalization, excess weld penetration and various dents were also verified.
After performing the run of the tools, the client was given the final report based on the international standard ASME B31.4-2016, in which the current status of the singularities of the pipeline and the cleanliness status were detailed.
Also, information was included that allowed the customer to know both the actual diameter and the minimum diameter of the pipeline, to later evaluate the passage of an intelligent tool.
