Painting & Coating Inspection Service

BDNDT Provide Painting & Coating Inspection Service in Bangladesh.

The word “coating” is a generic term and includes “painting”. The terms “coating” and “painting” are used
interchangeably throughout literature. In the most general terms, a “coating” is a protection against corrosion, where “painting” may have additional properties, such as color or ultraviolet screening pigments.
The other term often used together is “lining.” In general, when describing the coating of internal surfaces
of pipes or tanks, the term “lining” is also used, and to identify the coating of external surfaces the terms
“coating” or “painting” are always used.

Methods of Non-Destructive Testing of Concrete (Civil NDT)

We Know Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure, or system for characteristic differences or welding defects and discontinuities without causing damage to the original part. NDT is also known as non-destructive examination (NDE), non-destructive inspection (NDI), and non-destructive evaluation (NDE).

CIVIL NDT: Non-destructive tests (NDT) are test methods which are used to examine the hardened concrete structure for their suitability for its intended use without interfering in any way with the integrity of the material or its suitability for service.

Various non-destructive methods are commonly used of testing concrete have been developed to analyze properties of hardened concrete, which are given below.

 

1. Rebound Hammer Test

The rebound hammer test measures the elastic rebound of concrete and is primarily used for estimation of concrete strength and for comparative investigation.

02. Ultrasonic Pulse Velocity Test
It is used for the finding the compressive strength of concrete.

3. Carbonation Depth Measurement Test
This NDT Method is used to determine the depth of concrete affected due to combined attack of atmospheric carbon dioxide and moisture causing a reduction in level of alkalinity of concrete, and reinforcement may suffer from corrosion as a result.

4. Radiographic Test
Radiographic test is used to detect voids in the concrete and the position of stressing ducts.

5. Permeability Test
Permeability test of concrete structure Method is utilized to find the permeability which is the measure of flow of water through the concrete.

6. Acoustic Emission Techniques
These Method have been used to study the initiation and growth of cracks in concrete.

7. Penetration Resistance or Windsor Probe Test
This test is used to measure the surface hardness and hence the strength of the surface and near surface layers of the concrete.

8. Half-cell Electrical Potential Method
This NDT test is used to detect the corrosion potential of reinforcing bars in concrete.

9. Covermeter Test
This test method is used to measure the cover to reinforcement bars in structure and also the diameter of reinforcement used in existing member.

10. Sonic Integrity Test method
Sonic integrity test is using an instrumented hammer providing both sonic echo and transmission methods. It is broadly used to test the quality of concrete structures.

11. Tomographic Modelling

Tomographic modelling, which uses the data from ultrasonic transmission tests in two or more directions, is employed to detect voids in concrete.

12. Impact Echo Test
It is used to detect location and extent of defects such as cracks, voids, delamination, honeycombing and debonding in plain, reinforced concrete and post-tensioned concrete structural members.

13. Ground Penetrating Radar
Ground Penetrating radar or impulse radar testing is used to detect the position of reinforcing bars or stressing ducts. This method is used in place of radiographic inspection for inspection of post-tension cables, conduits in concrete and osition of reinforcement bars.

14. Infrared Thermography
This method is used to detect concrete defects such as voids, cracks, delamination and other anomalies in concrete. This method is also used to detect water entry points in buildings.

Cathodic Protection Service Provider in Bangladesh

We Know Cathodic protection is a method for preventing corrosion on submerged and underground metallic structures. Cathodic protection is commonly used to protect numerous structures against corrosion, such as ships, offshore floaters, subsea equipment, harbours, pipelines, tanks; basically all submerged or buried metal structures. The technique is based on converting active areas on a metal surface to passive, in other words making them the cathode of an electrochemical cell.

BDNDT.COM offers all aspects of Cathodic Protection services for buried Pipework,Tank, Vessel, Jetty etc. that include Design, Supply of Materials, Testing and Inspection,Installation, Pre-commissioning, Testing & Commissioning, Maintenance and Troubleshooting.

Visual Testing (VT) Inspection Service in Bangladesh

We know Visual testing (VT) is one of methods of non-destructive testing of optical type. It is based on obtaining information about the tested material with the help of visual observation or of optical and measuring instruments. The VT often precedes or is carried out together with other tests, and it is fundamental for the correct interpretation of results. Visual testing method allows detecting discontinuities, deviations of the size and shape from the specified ones for more than 0.1 mm when using instruments with magnification up to 10x.visual inspection has the aim to get a qualitative and dimensional analysis of the item according to specific acceptability criteria, whose evaluation must imply measurement instruments for an accurate sizing of the imperfections.

BDNDT started to provide Visual Testing (VT) testing Service provide in Bangladesh. The experience we have gathered in Visual Testing (VT) testing during the last five years has given us the confidence to extend the VT testing service to corrosion control and management if required.

What Does Dry Film Thickness (DFT) Mean?

Dry film thickness (DFT) also know as coating thickness gauge is the thickness of a coating as measured above the substrate. This can consist of a single layer or multiple layers. DFT is measured for cured coatings (after the coating dries). Dry Film Thickness is probably the most critical measurement in the coatings industry. It provides vital information as to the expected life of the substrate, the product’s fitness for purpose, its appearance and ensures compliance with a host of International Standards.The thickness of a coating depends on the application and type of process employed. Proper thickness should be determined by recommended coating system parameters.

A coating is the most critical component in an anticorrosive coating system. The main function of a coating is to provide corrosion protection by adhesion to the substrate. It is critical that the applied thickness be sufficient to ensure corrosion protection as well as proper adhesion.

Film thickness is measured to ensure its compliance with ASTM, ISO and other specifications. There are coating inspection tools that are used at every stage of the coating process to ensure DFT meets correct specifications.

Types of DFT gauges include:

  • Magnetic pull-off (Type I)
  • Constant pressure probe (Type II)
  • Electronic magnetic flux
  • Eddy current gauge

The standards concerning DFT measurements include:

  • ISO 2808
  • BS 3900 Part C5
  • BS 5494
  • ASTM D1005
  • D1400
  • D2691
  • SIS 184160
