Regular inspection of the wall thickness of pressure bearing equipment such as pipelines, containers, and reaction vessels is a key step in preventing leaks and ensuring safe operation during chemical production and equipment maintenance. However, traditional ultrasonic thickness gauges rely on coupling agents and have high surface requirements, especially in high-temperature, coated, or corrosive environments, which often limits their application. In response to these industry pain points,KODIN 3A-EM High Temperature Electromagnetic Ultrasonic Thickness GaugeThe characteristics of non-contact, no need for coupling agents, and high temperature resistance provide an efficient and reliable thickness measurement solution for the chemical industry.

1、 Facing the challenges of typical chemical working conditions

Chemical testing environments often have the following characteristics and impose strict requirements on testing equipment:

1）High temperature online detection: Many pipelines and equipment are operating continuously at high temperatures, and traditional methods require shutdown for cooling, which affects production.

2）The surface condition is complex: the outer wall of the equipment often has insulation layers, anti-corrosion coatings, rust or rough surfaces, and pre-treatment is time-consuming and labor-intensive.

3）High safety and efficiency requirements: It is necessary to obtain data quickly and accurately, and minimize the impact on normal production and personnel operations.

4）Diverse materials: involving various metal materials such as carbon steel, stainless steel, alloys, etc.

The design of KODIN 3A-EM was born to address these challenges.

II Core Advantage: Why is it suitable for chemical industry sites?

1. Truly achieve online high-temperature detection

Standard high temperature probe: can withstandAt a surface temperature of 800 ℃, thickness measurements can be taken on operating boiler pipes, high-temperature reactors, cracking furnace tubes, etc. without waiting for equipment cooling.

Non contact and lifting capability: The probe allows for a lifting distance of up to3mm (carbon steel), can penetrate thin insulation materials or directly measure slight corrosive substances.

2. No need for coupling agents, suitable for complex surfaces

By using electromagnetic ultrasound technology, no coupling agent is required, eliminating measurement errors caused by coupling agent evaporation, uneven application, or high temperature failure.

The requirements for the surface of the workpiece are extremely low. Coated, corroded, or rough surfaces usually do not require polishing treatment, greatly saving on-site preparation time and improving detection efficiency.

3. Intelligent and simple operation, intuitive and trustworthy data

A-scan waveform display: Both the host and the APP support real-time waveform display, which can intuitively judge the quality and consistency of the measurement signal and improve the reliability of the detection results.

Intelligent Connection and Sharing: ThroughWiFi connected tablet app enables richer B-scan imaging, big data management, and one click report generation, facilitating data traceability and analysis.

Temperature compensation function: Automatically performs temperature compensation to ensure the accuracy of measurement data in different temperature environments.

4. Durable and portable, suitable for harsh environments

All metal shell, sturdy and durable, capable of adapting to possible collisions and corrosive atmospheres in chemical plant areas.

Compact and lightweight in size (with a host weight of approximately)500g）， Built in long-lasting lithium battery, especially suitable for high-altitude, narrow space or large-scale inspection operations.

III Typical chemical application scenarios
