А. S. Annenkov et al. Operative ultrasonic inspection of pipelines
Productivity and reliability of ultrasonic inspection of pipelines can be increased by application of the small-sized devices with a multichannel flaw detector and multielement acoustic systems, and also by using express diagnostic techniques and specialised converters.
C. Collins. High definition X-ray inspection of oil and gas pipelines
The most widely used, reliable and time-proven method of non-destructive weld examination during pipeline construction is radiography. Two alternative on-site radiography methods are available for pipelines of nominal diameter above 150 mm (6 inches), namely the External and Internal techniques. The author draws attention to the Internal radiography with the pipeline X-ray crawler detailing its advantages.
B. Brodsky, Z. Martinek, S. Starman. The VIZUS 2000 System for the inspection of pipe welded joints
The article contains the description of the ultrasonic VIZUS 2000 System for in-field inspection of welded joints. VIZUS 2000 is a multichannel system of high efficiency and reliability. Independent channels allow giving 40 - 70 impulses to each millimeter of the weld instead of 5 - 10 impulses for a multiplexer system. The classic impulse method, TOFD, as well as the spectral method are used for on-line signal processing.
NDT in the UK
P. J. Mudge. A review of the industry
R. Shipp. NDT in the electricity supply industry
The Electricity Supply Industry (ESI) has made a very substantial contribution to the development of NDT in the UK. Many of the features we now know in the heavy industrial NDT sector have resulted from development work, initiatives and problem solving arising from the ESI. The work was fuelled by a large power station building programme and a nationalised industry which placed great store in science, engineering and technology. But a great change came in the mid-1980s. An economic recession stopped the plant building programme and privatisation split the industry. The ESI is now having to learn to live in a new world. This paper gives a brief history of these events, describes the current situation within the ESI and reviews future challenges.
T. McNulty. NDT in the UK petrochemical industry
The paper describes the role of NDT and Inspection in the UK's petro-chemical industry. The two principal NDT technician Certification Schemes used in the UK are the British PCN scheme and the American ASNT scheme. Conventional NDT is widely used for weld inspection and corrosion detection. The intrinsically safe isotope exposure device known as SCAR (Small Control Area Radiography) is described. The use of non-invasive and on-line NDT techniques is becoming important as operational and cost benefits for plant owners become more obvious. Often these techniques are aimed at the rapid screening of pipework for the detection of Corrosion under Insulation (CUI). The Long Range Ultrasonic Testing (LRUT) technique is described. This technique provides a testing method for buried, thermally insulated or otherwise inaccessible pipe, over a range of many tens of metres. The technique is quick, easy to apply and will detect pipe wall cross sectional metal loss of 10% or better. The use of Electromagnetic Acoustic Transducers (EMAT's), Time of Flight Diffraction (TOFD), AC Field Measurement (ACFM) and inspection software databases are also briefly described.

A. Vajpayee. Detection of Internal and External Pits from Outside of a Pipe with New Technology.
In-line inspection tools are commonly used to detect and locate pitting on pipelines with high accuracy; however, after excavation it is not always known exactly where the pitted area is located. External coatings must be removed and the pipe cleaned down to bare metal with sand-blast or other techniques, so that supplemental NDT techniques can be employed to locate the pitting and confirm its dimensions prior to repairs. A new technology has been developed, with industry support, to locate pits through coatings and deposits. Pit depths and remaining wall thickness can be sized, and pitted areas can be mapped out. Where access is provided to the inside of the pipe, a second (internal) tool, using the same multi-channel technology, can be used to scan up to 100 meters from the access point .
