OUR HISTORY
Arctest was founded in September 1997, when SGS (Societé Generalé de
Surveillance), after 23 years in Brazil, decide to sell the NDT department to the
own CEO in Brazil.
The former CEO Alan Roberto Chanbom invite others directors and managers to
join in the raise of the company, now called ARCtest.
In almost 15 years, Arctest raise your operation status from 80 to 490 technicians
in NDT area.
Today, arctest run with 68 Iridium, 23 Selenium and 2 Cobalt sources, and 3 X-ray
equipments.
With investments, hard work and safe radioprotection, Arctest receive the ISO
9001 seal and became a largest NDT company in Brazil.
In the late 80s, seeking medical applications, companies around the world began
to develop a two-dimensional X-ray detector called Image Plate (IP), with the aim
of replacing the traditional radiographic film.
The need to reduce the radiation dosis and provide better image contrast with low
noise is a big incentive to research new products. The rapid replacement of
radiography with intensifying screens for computer systems has brought many
operational advantages, such as the electronic archive of images and post-image
processing.
However, it created the need to acquire new knowledge, concepts and modification
of existing procedures and brought out a new set of problems to be solved.
In computed radiography, the concept of image quality has a new meaning and
interpretation due to their unique attributes, the contrast and brightness of the
final image can be manipulated with the pre-digital signal processing.
ARCTEST, as leading-edge company in several new technologies in the field of nondestructive testing
and more specifically in the area of radiographic testing, improved and developed in Brazil the
technique of computed radiography (CR).
For more than 14 years, ARCTEST has been developing, testing and improving new techniques, so there
is a constant cleaning in the area of Radiation Safety and also make the computed radiography (CR) an
important tool, quick, safe and reliable, which undoubtedly in a few years, will replace the currently
used industrial radiography.
This search has been highlighting the pioneering ARCTEST worldwide and is recommended by
manufacturers of RC systems, certification bodies and customers served.
The ARCTEST was the first company worldwide to describe an operational procedure for checking the
physical condition (corrosion), even before bodies such as ASME and BSI create RC Standards.
Already using the RC since August 1998 with Gendex systems, was necessary to qualify the procedure
again when Petrobras launched its standard (N-2820) in December 2007.
Also in 2007, Petrobras issued the standard N-2821, where he started, along with
national and international bodies, the process of qualification and validation of welded joints
in RC.
The process took place in three stages, and reached the final after 2.5 years.
First, Petrobras invited to the process six manufacturers of RC systems, including:
Dürr, Kodak, GE, Gendex, CIT and Fuji (declined the invitation)
To operate the systems, were invited companies providing service in the industry:
Arctest and four other companies.
The "division" of the sets was decided as follows:
Arctest represent Gendex and Kodak
Company 2 represent the GE Company
Company 3 represent the company Dürr
Company 4 represent the company CIT
Company 5 (which would represent the Fuji) also ended up representing the Kodak
For the qualification process, Petrobras fabricate 756 joints, all with flaws, divided into
four sets of 21 spools with 9 joints each.
Each spool had a combination of diameter x thickness.
Phase 1 – X-ray of 5 diameter x thickness different joints.
At this stage all service providers performed radiographs.
Gendex Equipment (represented by Arctest) failed the tests.
Phase 2 - Radiograph of 21 spools with RC and RG for comparison, using X-rays, and
Iridium Selenium (In Bunker)
The second company did not reach the level of quality equipment Dürr, which
transferred to the representation of Arctest.
The third company initially tried a partnership with Arctest, but ended up passing the
equipment for the CIT Arctest finalize the process.
At this stage no equipment could reach the level of quality required by gamma rays
(Iridium and Selenium). Only with the use of X-ray
For the next phase, there were only:
ARCtest (Dürr, Kodak and CIT) and the 5th Company (GE).
Thereafter the CIT would request the equipment back to England, giving up the 3rd phase of qualification.
Stage 3 - Radiograph of 21 spools with RC ( On Site)
At this stage Arctest complete the process qualifying 19 (of 21) combinations for the Kodak system and 19 combinations for the Dürr system.
The company 5 completed the qualifying 5 combinations with GE equipment.
After the process, SNQC (National Qualification and Certification System) presented the results at the congress NDT and Technical Diagnostics in Russia.
Arctest starts the Ecovap project, executing 731 joints from February to September 2010.
CR DEVELOPMENT
Today, due to the know-how given to ARCTEST, RC system manufacturers use this acquired
knowledge to develop their products, with examples:
KODAK
- Analysis of Software for better optimize to daily operations
-Tests with the new system HPX-1
-- Comparative tests between commercial IP and IP under development (BL / WH)
GE
- Partnership with Eletronuclear, carrying out several tests with GE systems.
- Tests with the new CRFlex and CR 25
VMI
- FMC Client. VMI scanner Operation on Rio de Janeiro site, after recommendation from
Petrobras.

Welds
Diameter x thickness combinations
For the initial use of the RC in welds were qualified thickness ranges according to the scope of work, which consisted in pipes of ¾ "to 3 ½" of 40 to XXS schedules.
The test are not limited to these combinations, but for use in other combinations should be followed the validation processes, by the following steps:
- Computerized Radiography for one or more specimens with defects.
- Comparison to conventional radiography
- Fill RQPEND (NDT Process Qualification Report)
- Send to SNQC for evaluation and release
CR APPLICATIONS
Weld
- Top speed in obtaining results
- Lower area isolation
- Loss of exposures far below than RT
- Features information and mapping with high accuracy
- Images viewing resources
- Standardized reports
- Remote Monitoring of work
- Less physical storage space use

Both for corrosion than for weld, we can understand the need to replace the RT by CR in the world.
Each and every process in the world continues at an incredible speed of modernization, technology, improvements and standardization.
