Abstract: The article summarizes the international and Russian experience in the development and operation of devices for full-scale testing of pipes and also discusses the requirements for a new design of the devices for hydraulic testing of pipes under combined loading with internal pressure and bending.
Also, the article summarizes typical schemes of pipe loading in the process of testing and variants of applying loads in time.
The analysis of the requirements for the test devices includes consideration of the main components of the hydraulic installation for cyclic pressure loading and the device for applying the bending moment as well as requirements for the placement of test devices equipment.
The results of the analysis demonstrate that the construction of a new test devices will allow testing the entire range of pipes in use with the purpose of assigning actual reliability values and safe service periods, introducing correction factors into design models (in case of non-compliance of estimated and actual values), determining maintenance and repair schedules.

Keywords: testing device, full-scale pipe sample, bending, internal pressure
