Ultrasonic thickness gauge simultaneously measures the thickness of the epoxy paint and anti-corrosion paint on the surface of the asbestos board.

The porosity and fibrous structure of asbestos materials form a waterproof layer that effectively blocks water molecules from passing through, preventing moisture penetration. They are high-temperature resistant, corrosion-resistant, wear-resistant, low-density, highly elastic, and have low thermal conductivity, making them suitable for various environmental conditions. Surface treatment for corrosion resistance extends their service life and enhances safety performance. Non-fibrous cement asbestos boards are a green and environmentally friendly material, with advantages such as water resistance, fire resistance, crack resistance, and corrosion resistance, thus having a wide application prospect in the construction industry, hydraulic engineering, and other fields.

How to correctly choose a high-temperature coupling agent for high-temperature measurement

Ultrasonic coupling agents are essential consumables in contact ultrasonic testing. Industrial coupling agents are used to eliminate the air between the probe and the object being tested, allowing ultrasonic waves to effectively penetrate the workpiece to achieve the detection purpose. If the coupling is poor and there is an air layer between the probe and the inspected workpiece, it will affect the effective transmission of ultrasonic waves, making conventional testing impossible.

Ultrasonic probe cable that can replace imports

The cable is also called an ultrasonic probe cable, which is a high-frequency coaxial cable used to connect the ultrasonic probe with the ultrasonic flaw detector/thickness gauge. This coaxial cable can eliminate the influence of external electromagnetic waves on the excitation pulses emitted by the ultrasonic probe and the echo pulses received, and prevent the high-frequency pulses within the probe cable from radiating outward in the form of electromagnetic waves.

How to detect pitting in industrial pipeline wall thickness inspection in advance.

Pitting corrosion, as the initial stage of corrosive damage, occurs when the metal surface is subjected to tensile stress or chemical substances, leading to the destruction of the protective layer and the formation of localized penetration. This exposes the metal substrate directly to the corrosive environment, resulting in the formation of localized corrosion pits that develop deeper. Typically, fatigue sources are easily formed in areas where pitting occurs. The formation of corrosion pits on the structural surface alters the surface state of the structure, subsequently leading to localized or overall damage.
