Inspect inaccessible facilities including pipelines in concrete insulation and pipelines with complex geometric shapes
The history of PDT began in the well-known submarine facility SEVMASH where in 1973 the technique’s inventor and DIATECH's Vice President for Science and Technology, Professor V.K. Shuhostanov first applied PDT by testing submarine pressure hulls.
Technical capabilities of Phonon Diagnostics Technique allows it to inspect inaccessible facilities including pipelines in concrete insulation and pipelines with complex geometric shapes, pipe sections passing above and below river.
An interaction of material and energy appears in a component under operating conditions, i.e. the energy supplied from the outside interacts with material. As a result of this energy interaction, there are processes of redistribution, concentration and release (emission) of energy by the material. Phonon emission PhE is formed in the material and around it.
A good example of PDT applied on pipelines is a project performed on gas pipelines located on a landslide slope of Kama river, which are part of the 9-lines Uzhgorod corridor (see Figure 1). The arrangement of the system equipment is shown in Figure 2. Example layout of PDT inspection and monitoring results for Line 1 (Urengoy-Uzhgorod gas pipeline) on the landslide slope at the first (a) and second (b) stages of inspection is shown in Figure 3.

Phonon Diagnostics Technique is actively developing and is successfully applied on different types of facilities including main pipelines. It is confirmed by well-known international organizations as Bureau Veritas, Russian Maritime Register of Shipping, as well as numerous reviews of global oil and gas companies: Total, Conoco Phillips, Cepsa, Repsol, SINOPEC, Gazprom, Rosneft, Lukoil and others.
