[0012] 4. Presentation of the state of the art

[0013] The current state of the art stipulates that during checks and tests at periodic control due CP (RI + IP), internal revision and pressure test, for the evaluation of the technical condition of pressure vessels and pressure pipes, the checks and tests should be carried out with these vessels and pipes removed from the installation, emptied, isolated from the rest of the installation, following which the tests will be made hydraulically and / or pneumatically with nitrogen or air if the manufacturer and / or the designer allows the tests to be performed with these fluids: water, nitrogen, air.

[0014] If it is not allowed to carry out these tests with these fluids, due to contamination considerations, (medicine and research in physics and nuclear engineering), (wind tunnel aviation research), or if it is not allowed to carry out hydraulic tests because of the volume size and weight; or if the performance of pneumatic tests with air or nitrogen is not allowed, or if the pressure test with air or nitrogen cannot be performed due to the fact that the required flow and pressure cannot be ensured at the value of the sealing pressure or, at the value of the test pressure resistance Plest(bar) the need to solve this technical problem arose.

[0015] 5. Presentation of the technical problem that the invention solves and presentation of the advantages in relation to the state of the art 12.2.- Description of the invention continuation

[0016] The invention solves the technical problems in the fields of applicability presented above under the conditions in which: it is not allowed to carry out samples and tests at IMSP - mechanical installations under pressure: fluid containers and pipes for contamination reasons it is not allowed to carry out the hydraulic test due to the large volume of the weight and the lack of the possibility of raising the pressure to the required value Piling (bar), P test (bar) the flow of air and / or nitrogen cannot be ensured at the required pressure

[0017] The problem is solved by the presented invention, by checks and tests in the installation / equipment of which these IMPS are a part (mechanical installations under pressure - containers and pipes), without removing them from the installation, without emptying the installation and these IMPS.

[0018] Checks and tests being done with the working fluid at the working pressure in the distinct loop.

[0019] I specify that the national regulatory authority in the field of pressure equipment, ISCIR admits and accepts this Procedure of checks and tests, samples and the European and international certification body on the Brussels list, Tt / KAustria with REXNAR accreditation for pressure equipment 97 / 23 / EC accepts and has issued the certifications for this field of applicability with European recognition. I am attaching the PE of the ISCIR accepting the procedure for this field of applicability.

[0020] The invention solves the high technical problems that did not have a solution, it is a process - a method, an operational procedure that reduces the time of checks, tests at facilities and complex equipment in which containers and pipes under pressure are mounted and installed from 25 + 30 days to 3 + 4 days, the savings being considerable, not having to remove these containers, pipes, installations, equipment from operation, not having to empty them, mounting, installing, carrying out tests in the installation / equipment.

[0021] 6. Disclosure o f the Invention as claimed - invention with the title Procedure - practice - method of checks and samples containers and pipes with oxygen, nitrogen, argon, CO2, H2, medical air and industrial air and Presentation of Advantages in Relation to the State of the Art

[0022] Checks and tests at the due date of the mechanical installation under pressure, vessels and pipes CP - periodic control (R1 + IP) - internal revision + pressure test - are done in order to evaluate their technical condition for safe operation, checks and tests that are carried out based on the (procedure) of this procedure, - practice - verification method, which is the object of the invention patent application.

[0023] The procedure -practice - method of checking and testing containers and pipes with oxygen, nitrogen, argon, CO2, Hi, medical air and industrial air which is the subject of the invention patent application is characterized by the fact that:

[0024] It does not require the removal, dismantling and emptying of containers and pipes for fluids from the installation in which they are mounted, installed.

[0025] It does not require the redeployment and installation of containers and pipes from the installation from which they were dismantled for carrying out the tests

[0026] Checks and tests are done with the installation of which these containers and pipes are part in working condition without stopping and emptying the installation 12.2.- continuation

[0027] Checks and tests are done with the working fluid, at the working pressure, at the operating pressure of the installation in a separate loop

[0028] Since the hydraulic test is not possible due to contamination and / or due to the high volume and weight of the working fluid, checks and tests are done with working fluid, considerably reducing the time of checks and costs

[0029] Since the pneumatic tests cannot be performed due to the volume, high fluid flow rate and the lack of possibility to raise the pressure to the required values of pressure P tightness (bar), and Presistence (bar) the tests and checks are done with the working fluid, at the effective working pressure, reducing - considerable trial times, reducing related costs, greatly reducing test pressures and at the same time solving the technical problem of rising the pressure to high values in containers and pipes with very large volumes and very high pressures.
