The method of checks and tests of pressure vessels and tanks for crimping

Abstract

A method of checks and tests of pressure vessel and tanks under pressure with oil and air is the subject-matter of the invention. The method for checks and tests comprises shutting down and putting the installation back into operation after carrying out checks and tests. The method is characterized by the fact that the installation of which the containers and tanks, the pipes are part, remains in working condition, does not require their emptying. The checks and tests are done with working fluid at working pressure with authorization to operate at the technical characteristics - parameters guaranteed by the manufacturer or established by technical expertise.

[0012] The invention relates to ths technical fields betow:

[0013] - Industry

[0014] - Production linos and technological lines with eccentric presses with pneumo- hydraulic actuation, presses with hydraulic, pneumatic actuation (from the car manufacturing industry)

[0015] - Hydropower plants - CHE- with lubrication groups G.U.P,

[0016] • Installations and equipment with hydraulic and pneumatic drives from various fields

[0017] 4. Prasenfafw t of tee current state of the art

[0018] The current state of (he art stipulates that checks and tests at the CP (Pt + IP) maturity of periodical control (Technical review + Pressure test) for the evaluation of the technical condition of containers and tanks and connecting pipes under pressure, shouid be done with these containers and tanks stopped from operation, taken out of operation, emptied, isolated from the rest of ths installation following the tests to ba done; hydraulic and / or pneumatic with nitrogen, air if the manufacturer and ths designer wanted these tests to be carried out.

[0019] The correct stats of the art provides far the performance of resistance tests Pt«« (bar) ~ 15 min and the tightness test at pressure P4(bar) 30 min •* 60 min with the working fluid established in the construction technical book and mentioned on th® stamp piste. 12.2 ~ (tontfoUStfoh

[0020] S. Presentation of rfte tec / J.tecs / probf&n h‘?at the inverrlfon solves end / weenteffoo of tbs advantegss in re.taflor? to the state of the art.

[0021] The invention solves the teohnicsl problems in the fields of applicability presented under the conditions in which:

[0022] - it is not necessary to stop, remove from the installation and / w isotate, empty containers and tanks in order to cany out checks and samples it is not allowed to carry out hydraulic tests due to contamination considerations air and / or nitrogen flow and pressure cannot be ensured

[0023] - it is not possible to stop tee operation and empty the insfafiations / eguipment in which the tanks and containers are mounted

[0024] Solving the technical problem is done by tea invention presented by checks and tests in the installalkxvEqufomenl of which these IMSPs are a part (mechanical installations under pressure and pipelines), without removing them from the installation, without stopping and without emptying the installation, checking and doing tests -ss with the working fluid, at the working pressure in a distinct loop.

[0025] I specify that the national regulatory authority in the field of pressure equipment IMSP - mechanical installations under pressure, admits and accepts this Procedure of checks and tests and the European and international certification body on the Brussels list, TUV Austria with RENAR accreditation, for equipment under pressure 97 / 23CE accepts end admits this procedure for this field of applicability and has issued national and European certificauo^s

[0026] Protocol of technical verification Nd. 51 C ~ 100 / 20.102321 of Acceptance of the Procedure.

[0027] The invention solves the technical problems that had no solution, . it is a procedure - an operative method procedure that reduces the lime of checks, tests at installations, comptex equipment groups in which tea containers and tanks with this working fluid under pressure, from 10 * 16 days to 1 *■ 2 days, the savings being considerable, not having to stop, emptying these complex installations, not having to dismantle and / or isolate and remove these containers and tanks from ths instatiations in order to check and carry out samples and reassemble them in the Installations.

[0029] The Invention with the title Procedure - practice - method of checks and samples pressure vessels and tanks with oil. air oil, air / oii, Air (and oil} and the presentation of the advantages in retation to the current state of the art.

[0030] Checks and tests at periodic control due at 1 (one) * 4 (four years) of IMS? - mechanical installations under pressure, containers, tanks, pipelines for fluid CP ~ periodic: control (Rl + IP) (infernal review + Pressure test ) are done in order to evaluate their technical condition for safe operation. Checks, tests that are canted out based on this procedure that Is the subject of the patent application.

[0031] The procedure - practice ~ method is characterized by the fact that:

[0032] ~ applies to the field of applicability' presented, to the technical field presented with the technical characteristics and technical parameters of the presented invention. ,2 ~ aontmuotion

[0033] - does not require disassembly and / or isolation. removal of containers. pressure tanks from the installation, equipment, group in which they are installed- installed

[0034] - does not require stopping, emptying, decommissioning

[0035] - it is performed with rhe plant and containers and tanks in working condition

[0036] - it is performed wth the working fluid existing in the installation, containers, tanks at the working pressure

[0037] - does not require reassembly and reinstaliafion after checks and tests

[0038] - since the hydraulc test is not possible for masons of contamination and / or for reasons of high votome and weight of the test fluid, checks and tests are done with working fluid at working pressure.

[0039] - the time and period of cheeks and samples is considerably reduced ton W * 16 days to 1 * 2 days

[0040] - since pneumatic tests cannot be performed due to the volume, high fluid flow. and the lack of possibility of raising the pressure to high Pw (bar) and P&^sss (bar) vetoes, the tests and checks are done with the working fluid at the working pressure, reducing considerable costs related to these checks and tests.
