Non-destructive testing: Investigation of concrete structures

[Confident in Technical Skills] Leave the deterioration diagnosis of existing civil engineering structures, full-scale surveys, reinforcement studies, and seismic assessments to us. We also accept individual investigations.

We will investigate the deterioration of concrete structures (such as bridges and buildings), which are social capital, and create data for repair plans. When implementing seismic reinforcement work on structures like bridge piers, we will conduct preliminary rebar surveys to ensure the smooth progress of the construction. 【Individual Surveys】 - Measurement of crack depth using ultrasound (bridge piers) - Data on crack depth using ultrasound - Investigation of internal defects in concrete using X-ray imaging (deck slabs of elevated bridges) - Measurement of concrete thickness using ultrasound - Investigation of internal defects in concrete using ultrasound - Measurement of sound velocity in concrete using ultrasound, etc. *For details, please contact us or refer to the catalog.

Non-destructive testing "Ultrasonic Testing (UT)"

We are confident in our technical capabilities. We play a role in ensuring safety and reliability through non-destructive testing. Leave it to the professionals who hold numerous technical qualifications.

Ultrasonic Thickness Measurement Ultrasonic thickness measurement is a method of measuring the thickness of an object from one side using ultrasonic waves. It is typically measured with a specialized device called an ultrasonic thickness gauge. Ultrasonic waves are sent from the measurement surface of the object, and the time it takes for the reflection from the opposite side to return is measured and converted into thickness. A sensor called a transducer (probe) is used to transmit and receive the ultrasonic waves. ◎ Implementation of Ultrasonic Thickness Measurement Ultrasonic thickness measurement is conducted in accordance with the standard "Thickness Measurement Method Using Ultrasonic Pulse Reflection" (JIS Z 2355). Furthermore, the standard states that "the person conducting the measurement must possess the necessary qualifications or equivalent sufficient knowledge, skills, and experience." The "necessary qualifications" referred to here typically means individuals certified in ultrasonic testing by the Japan Non-Destructive Testing Association. *For more details, please contact us or refer to the catalog.

Non-destructive testing "Concrete X-ray inspection"

X-ray inspection that can detect electrical wires and gas pipes inside concrete! Prevents damage to buried objects before it occurs.

"Concrete X-ray inspection" is a method to confirm embedded objects such as rebar, electrical wires, and gas pipes inside concrete using X-ray images. In renovation work for buildings that are over ten years old and in seismic reinforcement work for structures, it is common to drill holes in concrete. This method can prevent damage to embedded objects like electrical wires and gas pipes inside the concrete. Just like taking an X-ray of the chest, X-ray images of concrete floors and walls are taken to check the condition inside the concrete using film. [Features] - X-ray inspection - Prevention of damage to embedded objects - Ability to confirm the interior of concrete - Verification possible with X-ray images *For more details, please refer to the catalog or feel free to contact us.

Non-destructive testing "Helium leak test"

"We are confident in our technical capabilities." We detect minute leaks that allow helium gas with a molecular weight of 2 to pass through.

Leak testing is one of the key non-destructive testing methods that is considered important not only in Japan but also in various countries around the world, including Europe and the United States. As a result, it is widely implemented in various fields such as chemical plants, nuclear power, and space development. Consequently, engineers need to have sufficient knowledge and experience regarding the characteristics of vacuum and leakage. Helium leak testing includes various methods tailored to specific purposes, such as quantifying the amount of leakage by pressurizing the product with vacuum or helium gas, and identifying leak points from invisible cracks. To meet the diverse needs of a wide range of customers, we are committed to ongoing engineer training. Additionally, for specialized products, we also conduct mock-up tests to validate the effectiveness of the testing methods. *For more details, please contact us or refer to our catalog.*

Non-destructive testing "Radiographic Testing (RT)"

"We are confident in our technical skills." We play a role in ensuring safety and reliability through non-destructive testing. Leave it to the professionals who hold numerous technical qualifications.

<X-ray Transmission Testing> With high defect detection accuracy and the advantage of being able to retain X-ray film, this method has become the most commonly used testing method today. Using a portable X-ray device combined with film and sensitizing paper, it is possible to capture images of steel up to 80mm thick and concrete up to 400mm thick. <Concrete X-ray Exploration> There has been an increase in renovation work on buildings that are over a decade old, and during these renovations, it is common to drill holes in the concrete using core drills. Inside the concrete, there are embedded items such as rebar, electrical wires, and gas pipes. By exploring the interior of the concrete with X-rays in advance, it is possible to prevent damage to these embedded items. The X-ray exploration method involves taking X-ray images of concrete floors and walls, similar to how we take chest X-rays, allowing us to check the condition inside the concrete using film. <γ-ray Transmission Testing> Gamma rays are used for investigating the corrosion levels inside complexly shaped cast steel products and boiler tubes. Our company has a wealth of experience in handling various notifications to government agencies and conducting on-site inspections using dedicated irradiation rooms. *For more details, please contact us or refer to our catalog.*

Non-destructive testing "Helium leak test" [Problem solving]

Detecting a tiny leak through which helium gas with a molecular weight of 2 is permeating!

Helium leak testing is one of the non-destructive inspections that is considered important not only in Japan but also in various countries around the world, including Europe and the United States. It is widely conducted in various fields such as chemical plants, nuclear power, and space development, and engineers need to have sufficient knowledge and experience regarding the characteristics of vacuum and leakage. There are various inspection methods tailored to specific purposes, such as quantifying the amount of leakage by pressurizing the inside of a product with vacuum or helium gas, and identifying leak points from invisible cracks. [Customer's Issue] There has been a phenomenon where the building's air conditioning (absorption chiller) does not heat or cool properly, necessitating urgent action from the supplier. [Solution] Conduct a leak test after vacuuming the piping system using helium leak testing to identify the leak points. The manufacturer will repair the identified areas, and a re-inspection will be carried out to confirm that there are no leaks. *For more details, please contact us or refer to the PDF.
