Expertise Areas

LABORATORIES

CTDUT has full-scale facilities and research laboratories for the testing of products and services used in the pipeline mesh. An infrastructure that offers technical and economic advantages to both suppliers and operators (considering the high risk and high cost of conducting tests in active pipelines).

DESCRIPTION OF THE LABORATORIES

PIPELINE OF 14’’

Also called LOOP14, it consists a 14’’ circuit with 100 meters in length, equipped with several flared and easily removable spools. These spools have caused and mapped defects, facilitating the evaluation of new tools for inspection of pipeline integrity. New reels can be produced and included to attend specific needs of new developments.

The loop has a pumping system and two cannons to launch and receive PIGs.

It can be operated with water or inert gas.

Flow in the test with water: 190 to 320 m³/h in expansion for 190 to 640m³/h

Configuration: aerial, flanged spools, nearby launcher and receiver cannons

APPLICABILITIES

PIG’s testing and evaluation plus integrity inspection tools

Operator’s Training and Certification

Tests of Leak detection

LABORATORY OF CATHODIC PROTECTION AND COATING – “LPCR”

External Corrosion is one of the major hazards to the integrity of the pipelines. The main techniques to prevent and control this threat are the anticorrosive coatings and cathodic protection. The knowledge and development of these techniques are crucial for a new scenario in the pipeline area, with its increase, aging and constant change of the requirements of the operational safety.

LPCR has a complete infrastructure dedicated to the studies of cathodic protection.

It is designed to evaluate and test new products and equipment, train and qualify professionals, make researches, evaluate and develop anticorrosive coatings e parameters of cathodic protection in controlled space.

LABORATORY FOROIL PIPELINE OF 12” TESTS

The Oil Pipeline of 12” tests is a dedicated terminal with a piping of 12’’ for multiphase use with crude oil and byproducts, ethanol or water. It is possible to customize the installation through interchangeable spools, with flanges, which can simulate faults or conditions of interest.

Several flow and pressure meters distributed in the line allow testing and evaluation of the performance of the product. In multiphase operation, the flow meters located in the input lines allow the control of the mixture of different products.

The main advantages of using this installation for testing are the risk reduction during the tests and more flexibility to change the parameters of operation of the line during the tests, without causing impact on the transport installations by actual pipelines in operation.

PROJECTS IN PROGRESS

 

Project 1

Minimization of the operational impact of solid particles on pipes in Pressure Reducing Stations – PRS.

Client: National Institute of Technology – INT, through Project with PETROBRAS/CENPES (Project PT -144.01.13408 – SIGITEC 2017/00516-8)

It is a project to evaluate the effects of speed on the release of corrosion particles on pipes, resulting from the drag of the gas and to evaluate the technologies of filtration on the speeds identified as the most critical aiming to reduce issues related to clogging that happen in the Pressure Reduction Stations installed on field. To achieve this, an aerial pilot circuit will be built with a pipe of 16″and a Pressure Reduction Station – PRS, infrastructure available on CTDUT through the Project of FINEP – pilot circuit LOOPGAS.

Project 2

Study of metallic coatings applied by thermal spray for internal cathodic protection of welded joints in ducts and internally coated lines.

Client: National Institute of Technology – INT, through Project with PETROBRAS/CENPES (Project PT-144.01.13406 – SIGITEC 217/00360-8)

The project aims to evaluate and develop techniques of plating to protect welds made in internal joints, an admittedly fragile point of pipeline construction. It can be an excellent alternative to improve the reliability of internal corrosion in submarine gas pipelines in future and for the protection of pipelines with transport of liquids (oil and byproducts), containing produced or solubilized water.In this project several pilot sections submitted to different conditions using pipes of 16″ will be made as well as  infrastructure available on CTDUT through the Project of FINEP – pilot circuit LOOPGAS.
