The Raqeb Ultrasonic Scanner, developed by Pejvak Rayan Co., is an innovative R-Scan Corrosion Inspection Scanner designed to meet the demanding needs of industries such as oil and gas, petrochemicals, automotive manufacturing, and pressure vessel production. This advanced solution enables semi-automated, high-precision monitoring of wall thickness and corrosion on metallic pipes and storage tanks.1
The R-Scan Corrosion Scanner utilizes a wheel-type probe, dry coupling technology and a high-definition touchscreen interface to detect and measure internal surface corrosion with exceptional accuracy and speed. Unlike conventional systems, it requires no continuous application of water or gel, making it ideal for field conditions and limited-access inspections. The scanner collects and stores real-time test data both numerically and graphically, including A-Scan, B-Scan and heat map visualizations with full offline analysis and reporting capabilities.2
Engineered for ergonomics and field usability, the Raqeb scanner is lightweight, supports inspection over coated surfaces and features user-friendly controls and robust data management.3
These competitive advantages make it a highly efficient and cost-effective alternative to imported ultrasonic corrosion scanners.4
With its innovative design and proven industrial performance, Raqeb offers a reliable and scalable solution for comprehensive corrosion inspection across a wide range of metallic assets.5
Pejvak Rayan Company offers ultrasonic orrosion mapping (AUT) and various types of ultrasonic immersion scanners as part of its product portfolio.6
Tanks, pipelines, fittings, and valves are critical components of equipment used in the oil, gas, and petrochemical industries. Due to continuous exposure to stored fluids, these components are highly susceptible to corrosion over time.1
Corrosion typically manifests as a gradual reduction in wall thickness, resulting from the progressive loss of metal on the inner surfaces. This degradation may lead to structural defects, internal wall failure and eventually cause leaks, catastrophic failure or even explosions. Failure to detect corrosion in a timely manner can have severe and often irreversible consequences — including human casualties, substantial financial losses and serious environmental damage.2
With the rapid advancement of Non-Destructive Testing (NDT) technologies, it is now possible to inspect critical equipment without the need for disassembly or damage. Among these advanced methods, the use of high-precision Ultrasonic Scanners, such as the R-Scan Corrosion Scanner and other modern Corrosion Inspection Scanners, enables accurate detection of corrosion levels and precise measurement of remaining wall thickness. These cutting-edge tools significantly enhance the safety and operational reliability of industrial assets while also reducing inspection time and downtime in routine maintenance cycles.4
Ultrasonic Testing (UT) is one of the most reliable and widely used non-destructive testing (NDT) methods for corrosion detection and wall thickness measurement in metallic structures such as tanks and pipelines. Utilizing ultrasonic technology, this method enables precise evaluation of material condition without requiring access to the internal surface, making it ideal for in-service inspections and minimizing downtime.1
During ultrasonic testing, high-frequency sound waves are transmitted into the test material using an ultrasonic scanner. These waves are generated by a probe, which directs them through the component where they reflect off internal surfaces or discontinuities. Depending on the system configuration, the returning echoes are either captured by the same probe or by a separate receiving probe.2
Once captured, the ultrasonic signals are converted into electrical pulses for further processing. The testing unit then amplifies and filters the data, displaying it on the screen—typically as A-scan waveforms for detailed analysis.3
By analyzing the time delay between the transmitted and received echoes, and factoring in the known acoustic velocity of the material, the device accurately calculates the wall thickness at each measured point. This data is essential for assessing material loss due to corrosion.4
Advanced systems such as the R-Scan corrosion ultrasonic scanner and other high-resolution corrosion inspection scanners allow for automated and precise mapping of corrosion areas. These corrosion ultrasonic scanner improve inspection efficiency, ensure comprehensive data coverage, and support preventive maintenance strategies in critical infrastructure.5
Ultrasonic testing, especially when integrated with advanced scanning technologies, remains a cornerstone method in ensuring structural integrity and operational safety across various industries, including oil and gas, petrochemicals, and power generation.6
Model: PUS (CI 110) | Manufactured by Pejvak Rayan
The R-Scan (Raqeb) Ultrasonic Corrosion Inspection Scanner, model PUS (CI 110), is a semi-automatic system specifically developed for non-destructive thickness measurement and corrosion monitoring of metallic pipes and tanks. Designed and manufactured by Pejvak Rayan, this system is ideal for both ferrous and non-ferrous materials with outer diameters of 50 mm (2 inches) and above, and wall thicknesses ranging from 2 mm to 100 mm.1
This versatile ultrasonic scanner utilizes a portable, mouse-type probe that glides along the external surface of cylindrical or curved structures. The scanner emits ultrasonic waves into the material; the reflected signals are captured and processed to calculate precise wall thickness and detect internal corrosion or material loss.2
The inspection results are presented in multiple formats including: A-Scan, B-Scan, Digital Thickness Readout, Full-color Heat Map
For improved mobility and accuracy, the R-Scan is equipped with magnetic wheels and a precision encoder, enabling smooth, stable movement over curved or vertical surfaces. This allows for real-time, continuous scanning and full-profile thickness mapping, significantly enhancing inspection efficiency and reporting quality compared to traditional point-based thickness gauges.3
Offering a unique combination of portability, speed, and graphical data visualization, the R-Scan (Raqeb) model provides an advanced and reliable solution for corrosion inspection in various industrial applications, including petrochemical, power generation, water infrastructure, and pipeline maintenance.4
