oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. steel pipes are commonly used which can be subject to both internal and external corrosion. this paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. the pulsed eddy current (pec) method has been successfully ...

Oil–water emulsions are widely generated in industries, which may facilitate some processes (e.g., transportation of heavy oil, storage milk, synthesis chemicals or materials, etc.) lead to serious upgrading environmental issues pipeline plugging, corrosions equipment, water pollution, soil etc.). Herein, the sources, classification, formation, stabilization, and separation oil–water systematic...

The overall cost of structural corrosion is estimated to be in the order trillions dollars throughout world. This a fault that can bring numerous harms industries through water infiltrations, roof breaking and collapsing structures, even create work-related accidents. In this research, an artificial intelligence was developed evaluate aerial images factory roofs, aiming towards more accurate ef...

Safe pipeline transportation of energy resources is a major concern for the public. Since a pipeline has been built and buried, geologic hazards, corrosions and third-party damages all pose cumulative internal and environmental risks to the pipeline’s integrity. As today’s pipeline engineering and operation become more reliant on geospatial data for safety in the pipeline’s life cycle of design...

OBJECTIVES This study investigated whether coins of the new European currency (euro) corrode when they are exposed to gastric acid, and whether this change can be detected radiographically. METHODS The eight different denominations of coins were immersed for seven days in 0.15 N hydrochloride acid (HCl), which corresponds to the level of post-prandial gastric acid. A Swedish crown coin and th...

Titanium tubes generally exhibit superior resistance against electrochemical corrosions amid seawater for their passive films TiO2. However, hydrogenassisted corrosion (HAC) is actually the Achilles’ heel to titaniummaterials when the temperature exceeds near 70 8C. In this event, severe degradations like quick thinning and leakage were frequently detected on a large number of titanium tubes ex...

Computer-based structural health monitoring (SHM) systems are deployed in complex civil structures for continual sanity checks and early warning purposes. Skyscrapers, overextended bridges, oil refineries and pipelines are examples of civil structures that need to be continually monitored for corrosions, decays, stress and temperature change. Integrating multi-vendor SHM systems, which are tech...

We have developed a laser ultrasonic visualization(LUV) equipment. It can be used to study the ultrasound propagation in an arbitrary-shaped object, and also be used to the nondestructive inspection of materials and structures. The LUV equipment consists of the hardware and the software. The hardware consists of a pulsed laser, a scanning mirror (galvanometer scanner), an ultrasound sensor, a l...
