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

Online Corrosion Monitoring is a corrosion detection instruments and remote corrosion telemetry system that provides wireless ultrasonic inspection.1 The safest corrosion monitoring systems is the Pejvak Rayan wireless online ultrasonic corrosion monitoring system. This remote corrosion telemetry system uses wireless technology and ultrasonic technology to continuously and correctly monitor corrosion in pipelines, pressure vessels, valves, and fittings.2 Corrosion One of the most crucial pieces of equipment in the gas, oil, and petrochemical industries are tanks, pipelines, fittings, and valves. The materials that are kept inside of these gadgets cause corrosion over time.4 This corrosion occurs as the loss of metal from the inner wall after coming into contact with a liquid, which reduces the inner wall and leads to flaws and inner wall cracking. There are various ways that corrosion manifests itself, including penetrates from water droplets, embrittlement from hydrogen, and stress corrosion from sulfur during the refining process.5 The significance of corrosion detection Along with increased costs, problems like material leaking, chemical reactor or tank explosions, and catastrophic, frequently irreversible consequences to life, the economy, and the environment are also brought about by the deterioration of pipelines and storage tanks under pressure from corrosion and the inability to detect it in time.6 Early corrosion detection can be a very suitable and preventive soluti

Detecting lamination defects is critical for quality control in steel manufacturing. Pejvak Rayan developed the FLAW HUNTER UST9508, a state-of-the-art system for lamination and delamination detection in steel production. This system is a core component of any strip inspection system. It supports robust ultrasonic testing of steel plates and thorough sheet inspection. The FLAW HUNTER UST9508 improves defect detection in both ultrasonic testing of steel plates and sheet inspection. It is integrated into a complete strip inspection system for accuracy and efficiency in defect detection.1 For oversized or non-automated formats, we offer a semi-automated Plate Ultrasonic Testing Trolly that complements our strip inspection system. This equipment enhances quality of ultrasonic testing of steel plate lamination.2 Compliance with International Standards In the manufacturing of line pipes for oil and gas transmission, compliance with international standards such as API 5L, ISO 10893-9, and EN 10160 requires thorough UT inspection of plates to detect internal and surface defects including lamination, delamination, inclusions, and debonding. These structural flaws, if undetected, can compromise the integrity of the final welded pipes used in critical infrastructure. Technical standards typically mandate that a minimum of 25% of the plate’s effective width, along with 25 mm from each edge, be inspected to ensure defect-free performance in critical zones.3 Common Defects in Steel Plates
