... that have traditionally been used for monitoring corrosion in oil refineries. Two of the most common are corrosion probes and manual ultrasonic inspection. Intrusive Corrosion (or Electrical Resistance, ER) Probes Corrosion probes have been in use since the 1960s and are a very well-established technology...

..., but also reduce maintenance costs. Non-destructive testing like radiography/X-ray and ultrasonic testing are the common monitoring methods commonly used. This paper describes the application and effective use of such inspection techniques to enhance the reliability of inspection of storage tanks. Storage...

...Experimental Setup Figure 1 shows the experimental setup that is used to carry out the ultrasonic corrosion monitoring with permanently installed transducers. On one side of the 10 mm thick steel sample, a 3D-printed corrosion chamber is attached. During a corrosion experiment, the electrolyte...

... have not done any field installations with this equipment yet (as of November 2006). To gain experience, and for verification of the instrumentation, a number of lab experiments have been carried out using electrical DC current to stimulate corrosion as shown in Figure 2 below. Abstract Ultrasonics...

...Abstract An ultrasonic in-line inspection tool has successfully inspected a crude oil pipeline, which is 48-inches in diameter and 1287kms in length. This is one of the biggest crude oil pipeline systems in the world. The longest distance of a single inspection run is 1055 km. The survey runs have...

... and the riser in particular. In this description a new approach for a detailed ultrasonic inspection of the risers only is explained, based on the application of a compact umbilical (cable, tether) operated tool. This requires that the riser is bled down and liquid filled. The inspection tool provides on-line...

...On successful completion of the conceptual development a range of subsequent minor developments and improvements were initiated and these are further described in the section entitled “Conclusions”. Abstract This paper is concerned with a new non-invasive ultrasonic transducer for measuring...

... by process safety management regulations (OSHA 29 CFR 1910.119) are forcing more operators to conduct on-stream corrosion monitoring inspections. These inspections rely predominantly on the results of ultrasonic thickness (UT) measurements, which in turn are managed by using commercial software databases. UT...

...In order to be able to make a quantitative comparison of calculated and observed HIC crack growth rates, an experimental set up was developed enabling a simultaneous determination of the main parameters governing crack growth. By combining a hydrogen permeation set up with an ultrasonic monitoring...

... ultrasonic pigs have been developed. [ 1 ] (Off)loading lines and open risers often only provide single sided access and are not equipped with pig launch-and receive traps. For this category of pipelines, RTD developed cable operated ultrasonic pigs. This paper provides an overview of the possibilities...

...DISCUSSION There are many category classifications that could have been used, to group the tube results. Almost every tube is unique in its ultrasonic response. For example one boiler tube with a light deposit loading might give an R1 number of 16 and another boiler tube (from a different boiler...

... inspection tool using ultrasonic measurement technology has been developed by NKK Corporation with assistance from Alyeska Pipeline Service Company who is responsible for pipeline maintenance and inspection of the Trans Alaska Pipeline System (TAPS). This ultrasonic tool has succeeded in inspecting the wall...
