Other testing
Leak testing
TIGHTNESS TESTS, also called or included in the group of LEAK TESTS, are mainly carried out on pipes, bulkheads, tanks, pressure vessels, tanks, etc.
It is an effective test to verify the tightness of any element through which a fluid passes or is stored (at pressure equal to or different from atmospheric pressure) by detecting leaks or filtrations when exerting pressure with water or air.
Among the existing leak test methods, the most frequent and the ones BUQUELAND offers are:
- By direct pressure bubbling
- By bubbling with chamber or vacuum box
For LEAKAGE CONTROL of tank bottom welds, BUQUELAND carries out inspections by means of vacuum box equipment that is designed internally and manufactured according to the different configurations of the areas to be tested.
Ferrite testing
The determination of ferrite content in austenitic and duplex stainless steels is essential to ensure structural integrity.
When the ferrite content is too low this can lead to significant structural weaknesses and heat cracking. When it is too high, corrosion resistance, toughness and ductility may be affected.
This type of measurement can be done quickly, economically, accurately and non-destructively, on-site and at any stage of steel fabrication.
BUQUELAND has portable equipment for ferrite content measurement by magnetic induction for verification, for example, in austenitic steel welded joints on the same part and repair if necessary.
Coating thickness testing
Coating thicknesses are another parameter that can be easily measured by magnetic induction, non-destructively and with portable equipment. It is necessary for the base material to be magnetizable and the coating to be non-magnetic.
This method is suitable for measuring galvanic coatings such as zinc or chrome, as well as paints and plastics.
The measured signal is compared with a characteristic curve that is stored in the device. This characteristic curve is achieved through calibration.
As one of the parameters that most affect the measurement results is the surface roughness, BUQUELAND has equipment prepared with probes with large poles as well as 2-pole probes. These probes integrate the roughness profile and therefore reduce the scatter in the measured values.
Hardness testing
HARDNESS TESTS allow to determine, in a quick way, the resistance of a material to be damaged, scratched or penetrated by a piece of another material and its hardening state. In this way we can know that the harder a material is, the more resistant it will be to deformation, wear and tear.
Quantitative techniques for measuring the hardness of a material are based on applying pressure by means of a small indenter that is forced on the surface of the material to be tested under controlled conditions of load and application speed. The depth or size of the resulting footprint is measured, which is related to a standardized hardness number,
BUQUELAND provides:
- Obtaining measurements by means of portable hardness tester for Rockwell, Brinell and Vickers hardness tests.
- Determination of hardness before and after heat treatment of materials and welds.
Ultrasonic corrosion inspection
One of the biggest problems that industries have to face in their production processes is the corrosion to which metallic elements are subjected, specifically pipes, tanks, reservoirs, tanks or boilers, causing deterioration of the material, reduction of the original thickness, and even causing losses of fluid or raw materials.
Corrosion not detected in time can generate serious structural failures affecting even the safety of processes, personnel and facilities.
This is why specific periodic inspections are necessary, according to the legislation or regulations for each type of component depending on its use or internal requirements.
BUQUELAND offers Ultrasonic Corrosion Inspection for the detection of corrosion either conventional or Phased Array, obtaining a permanent record, in:
- Inspection of piping in industrial installations, maintenance and repair of vessels for pitting or corrosion localization
- Storage tanks and reservoirs; inspection of ferrules and bottoms
- Tank bottom inspection / mapping on vessels such as gas tankers, chemical tankers, FPSOs, etc.
