ROLL-UP FOR PNEUMATIC TESTS Russian patent published in 2019 - IPC G01N3/12 

FIELD: test equipment.

SUBSTANCE: invention relates to the field of roll-up for pneumatic testing of oil and gas equipment, can be used for testing in the conditions of the landfill. Roll-up for pneumatic tests according to the invention is made in the form of at least three structurally independent transportable modules having a closed rigid case, covering the bottom, roof and side surfaces of the module. Three modules above-mentioned include the observation and control data collection module, which contains the control and monitoring equipment, as well as the test module connected to it and the test module with the test object located in it, instrumentation and testing equipment, including a compressor and a receiver installed between the compressor and the test object, through which the compressor is connected to the test object, and a gas test medium storage module with storage tanks for the gas test medium. Moreover, the last two of these modules are interconnected by a pipeline supply and return gas test medium, one end of which is connected to the storage tanks of the gas test medium in the storage and distribution module of the gas test medium, and other end to the compressor in the test module thereof. In this case, the supply and return pipeline for the gas test medium is equipped with two bypass lines connected in parallel with the compressor to the receiver behind the compressor and to the pipeline in front of the compressor.

EFFECT: creation of roll-up for pneumatic tests with improved performance characteristics in terms of ensuring the possibility of safe testing at high pressures of the gas test medium and the reusability of the existing gas test medium in the storage module.
