Monitoring, auditing and supervision of construction steel.
Examination of macroscopic and microscopic structures of metals.
Order to satisfy the needs of its customers in terms of metallic constructions’ Reception and Supervision, TIC provides a team of well-performed engineers, technicians certified at least Level II, Cotend, Cofrend , ASNT et CSWIP using high-tech equipments (Scanner for the control LFET, Scorpion B-SCAN with all accessories, Portable XRF alloy analyser, Holiday detector, Coating Thickness Gauge, Vacuum Box, Flacon Tank flour system, etc … ).
A thickness measurement is a control of the thickness per point. The measuring points are randomly chosen to give a general idea about the thickness of the plate or the inspected equipment.
Besides, and at the request of the customer, measurement points can be identified by meshes.
The metal surfaces in contact with the probe must be free of calamine or any other substance that might interfere with the transmission of the echoes.
The readings should be compared with respect to the nominal thickness of the sheet and the volume of the defect is determined by the distance between its extreme positions.
Thickness measurement can be performed on equipment with the following grades:
Are excluded, examination of welded joints of the various grades of steel filler metals with a structure of austenitic-ferritic or austenitic.
Chemical analysis: This step is often a necessary preamble to the metallurgical expertise, to assess precisely the composition of metals and alloys. Bases analyzed: Iron, Nickel, Aluminium, Copper, Cobalt.
Chemical analysis using gas analyzers specific ways:
Mechanical tests are intended to characterize the material behavior and allow to obtain very precise information on the behavior of the part or specimen under duress, and to precisely quantify the deformation.
Infrared thermograph is the most widely used for inspecting the integrity of electrical systems. It has the advantages of being quick and easy contact. Although heat is not a perfect indicator of the problems in electrical systems, the heat produced by an abnormally high electrical resistance often precedes by power outages.
This same technique is proposed for the detection of surface corrosion in the fuselage parts.
There are a number of methods to detect corrosion. Corrosion mapping provides accurate measurement and a virtual image of corrosion damage. The images are dynamically analyzed to determine the damage, the comparison of images and the thickness data to determine corrosion rates.
It is a method which is based on an automated scanning system of flat metal surfaces connected to a computer. It is intended primarily for inspection of plates making up the fund and the shells of product storage tanks (water, oil, fuel, etc.) to provide a mapping of defects detected on both sides of the sheet (lower and upper).
The Scorpion DCP robot remotely controlled using a single wheel probe « combined with dry, » which eliminates the need for a traditional couple. This allows the robot to move vertically, horizontally or even upside down, while remaining fully functional. Compatible with any ultrasound system, an umbilical cable 50 meters provides access to the most distant point of most structures, without the need for scaffolding.
Site Master Battery power 30, the system is capable of operating continuously for 8 hours on a single charge and maximizes the time available for inspection.
The method of metallographic replica is non-destructive examination which is to make an imprint of a steel after fine polishing of the place’s surface (mirror finish).
Examination using replica gives a reliable picture of the microstructure of steel controlled about 0.1 to 0.3 mm below the surface.
Order to examine the result by enlarging the optical microscope in the laboratory, the technician makes an impression or replica with a sheet of acetate, soaked in acetone it poses to the area to look at that and then after drying it up between two glass slides.
This plastic sheet replicates the metallographic structure of steel with high fidelity.
This fully transparent sheet is then placed in the laboratory, in light of the optical microscope to visualize the behavior of crystal lattices.
The vibrations produced by the rotating machine efforts reflect a dynamics generated by moving parts such as: Electric Motors or thermal, turbines, generators, gears, gearboxes, compressors, etc.
Monitoring the vibration signature can detect this defect.
Techniques for vibration measurements and spectral analysis of signals collected are powerful and precise tools, allow to do mechanical diagnostic.
This type of control can detect defects through an organic coating applied on steel. Defects involved are cracks, inclusions conductive pinholes.
This involve a visual inspection of the external and internal condition of the equipment to identify areas containing visible damage to the eye.
Except for some equipment, the internal exam may not be possible, such as pipelines and small diameter pipes. As a result, such monitoring is performed remotely using special equipment called an endoscope.
Areas containing damage will be other inspections to measure the size of detected defects and their severity on the dependability of the equipment.
The hardness of a metal is its ability to resist deformation. It is determined by standardized tests (Brinell, Meyer, Vickers and Rockwell). By measuring the depth, diameter or other parameter of the impression made by a punch according to the test.
Consists of determination of the degree or type of alloy by quantitative analysis of the percentage of chemical components present. Identification is made by the technique of X-ray fluorescence spectrometry.
The test PMI will never be considered a substitute for certificates of material.
This is a visual inspection of quantity and quality of goods.
Control by the method’s ability to service (FFS) assessment is used to evaluate the components under pressure containing defects or damage.
This is a review that applies to dimensional hydrocarbon storage tanks and steel structures to verify compliance of the dimensions according to a plan approved manufacturing.
This is a review of the box sealing USING vacuum applied for the detection of defects similar to micro-pipes and affecting the entire thickness of a metal wall.
It is complementary to other tests and allows the detection of such leaks in containers within which it is not possible to create an overpressure.
The safety valve is used to protect equipment flow control damage caused by the unexpected increase in pressure. Such devices are commonly called « pop » or safety valves.
The valves are designed to open automatically at a predetermined pressure.
The simplest type and most reliable valve is the valve spring in which a spring force opposed to the system pressure acting on the valve. TIC provides the service of calibration of valves in accordance with current standards.
This is the verification and approval of design notes for equipment such as boilers, separators, etc. In accordance with code and construction standards.
The measurement of ferrite is a method of non-destructive control for determining the content of ferrite in given steel. This method is only applicable in a range from 0 to 80% iron in the case of stainless steel and duplex. The principle of measuring the number of ferrite is based on the principle of magnetic induction. A magnetic field generated by a coil interacts with the magnetic components of the room. Changes in the magnetic field induce a voltage proportional to the ferrite in a second coil. This voltage is then exploited. All components within the non-magnetic structure are recognized.
