Pipe Inspection System – Ultrasonic equipment

The FLAW HUNTER SLP 9503 is an advanced pipe inspection system designed for full-body evaluation of seamless steel pipes. As a state-of-the-art seamless pipe ultrasonic system, it ensures uncompromising quality control through precise detection of longitudinal and transverse flaws, laminations, corrosion, and wall thinning. Equipped with cutting-edge ultrasonic pipe inspection equipment, the system delivers outstanding accuracy and reliability in every inspection cycle.1

Engineered in compliance with API 5L, API 5CT, IPS, and IGS, this solution offers unmatched performance across critical industries including oil and gas, petrochemical, power generation, and automotive manufacturing. the seamless pipe inspection system covers pipe diameters from 2” to 24” and wall thicknesses up to 40 mm, making it suitable for a wide range of operational demands.2

Moreover, with modular channel configurations ranging from 32 to 64, advanced water column coupling technology, and high-speed automation, the FLAW HUNTER SLP 9503 guarantees complete body coverage at inspection speeds of up to one pipe per minute. Its intelligent software records every detail, processes results in real time, and generates clear, professional PDF reports for full traceability.1

Developed by Pejvak Rayan, this seamless pipe ultrasonic inspection system establishes a new benchmark in precision, productivity, and innovation — delivering confidence you can measure in every millimeter.1

Importance of Seamless Pipe Inspection

Seamless steel pipes play a vital role across critical industries such as power generation, oil and gas exploration and transmission, refineries, petrochemical plants, shipbuilding, boiler manufacturing, and the automotive sector. Not only are they valued for their exceptional strength, but they also withstand extreme internal and external pressures in highly demanding environments. Moreover, global statistics indicate that seamless pipes represent nearly 65% of the worldwide pipe manufacturing industry.1

Because these pipes are produced without welded joints, international standards including API 5L, API 5CT, IPS, and IGS require non-destructive testing (NDT) for strict quality control. As a result, implementing a seamless pipe ultrasonic inspection system with full-body inspection capability becomes indispensable — ensuring accurate detection of longitudinal and transverse flaws as well as precise measurement of wall thickness.1

Ultrasonic Testing in Seamless Pipe Evaluation

Among the most precise and widely used NDT techniques is ultrasonic testing. Particularly in pipes with wall thicknesses exceeding 10 mm, this method demonstrates excellent performance in detecting internal and external flaws, corrosion, and delamination.1

The seamless pipe ultrasonic testing process involves transmitting high-frequency ultrasonic waves into the pipe wall using a dedicated probe. These waves reflect off the inner surfaces and are received back by the same probe. The reflected signals are converted into electrical pulses and transmitted to the ultrasonic pipe inspection equipment. Once received, these signals are processed, filtered, and amplified to generate interpretable waveforms on the display.1

By calculating the time intervals between pulse reflections and using the known speed of sound in the material, the system determines the exact wall thickness of the pipe.1

Pejvak Rayan, a leading knowledge-based company, specializes in designing and manufacturing high-performance ultrasonic pipe inspection equipment and system. With a deep understanding of the challenges faced in critical industries, the company has developed a fully automated seamless pipe ultrasonic inspection system dedicated to offline full-body inspection of seamless steel pipes.1

This seamless pipe ultrasonic inspection system offers exceptional precision in flaw detection and thickness measurement, ensuring compliance with stringent quality standards. The system architecture includes multiple ultrasonic channels configured specifically to detect various internal and external anomalies across the entire surface area of the pipe.1

Overview of the Seamless Pipe Ultrasonic Inspection System, pejvak rayan

The FLAW HUNTER SLP 9503 is a fully automated, multi-channel seamless pipe ultrasonic inspection system engineered to perform high-resolution inspection, flaw detection, and wall thickness measurement of seamless steel pipes. Developed in alignment with global standards such as API 5L, API 5CT, IPS, and IGS, this seamless pipe ultrasonic inspection system guarantees full-body coverage either in offline mode or integrated within production lines.1

It can detect a wide range of standard reference defects, including 1.6 mm diameter through-holes, 6 mm FBH (Flat Bottom Hole) to 50% of wall thickness, and multiple longitudinal and transverse notches (N5, N10, N12.5) on both inner and outer surfaces of the pipe. Probes are mounted on carrier arms that traverse along a 13-meter boom, driven by a precision encoder. Simultaneously, the pipe rotates to allow spiral scanning, ensuring 100% body coverage.1

Channel Configuration and Inspection Capabilities

The seamless pipe ultrasonic inspection system (FLAW HUNTER SLP 9503) features an optimized arrangement of ultrasonic channels as follows:1

Eight Channels for Wall Thickness Measurement : These channels utilize pulse-echo techniques to measure pipe wall thickness at various positions along its length with exceptional accuracy.1

Twelve Channels for Longitudinal Flaw Detection: Probes in this group are arranged in two opposing sets of six, angled to emit ultrasonic waves in both clockwise and counter-clockwise directions. This enables the system to detect longitudinal cracks, lack of fusion, and other discontinuities on both inner and outer pipe surfaces.1

Twelve Channels for Transverse Flaw Detection: Similarly, these are configured in two opposing arrays of six probes each. They transmit ultrasonic waves in directions parallel to the pipe axis, effectively identifying transverse cracks, lamination defects, and other perpendicular discontinuities.1

Due to surface roughness caused by hot rolling and heat treatment processes, seamless pipes often exhibit inconsistent coupling conditions. Therefore, the system employs a water column technique to ensure uniform acoustic transmission and enhanced signal clarity during inspection.2

Advanced Features, Software, and System Expandability

To increase testing throughput (up to one pipe per minute), the seamless pipe ultrasonic inspection system is upgradeable to a dual-head configuration with 64 channels.1

This enhancement allows for simultaneous inspection of both halves of a 12-meter pipe, dramatically increasing productivity without compromising inspection resolution.1

The integrated software platform supports real-time visualization of 32 A-Scan and 32 Strip Chart channels simultaneously. Each test result is stored individually in PDF format and can be extracted via USB, CD, or exported to factory-wide data networks for comprehensive quality documentation.1

This intelligent ultrasonic pipe inspection equipment not only ensures superior accuracy but also delivers unmatched reliability for critical seamless pipe applications.1
