Problems solved by technology

[0002] In petroleum processing enterprises, large-scale anti-corrosion tanks are widely used in all aspects of production. Most of the current anti-corrosion tanks are steel parts, and the interior is rolled or sprayed with anti-corrosion layers, half of which are made of anti-corrosion plastics. In contact with corrosive liquids, there must be no leakage points in various parts of the anti-corrosion tank. Therefore, the requirements for anti-corrosion materials and processing technology are very high. After the anti-corrosion tank is processed, strict testing is required. The current test method is simple and has no effect on the characteristics of anti-corrosion plastics. Comprehensive understanding, so accurate and professional inspection results cannot be given, and accurate judgments on the market prospects of products cannot be made, which affects the development of enterprises

Embodiment 1

[0021] The anti-corrosion tank anti-leakage test method described in the present embodiment comprises the following steps:

[0022] (1) Set the anti-corrosion tank in an environment of 15°C, seal all the branches except the manhole with a cover plate, and set the manhole at the top of the anti-corrosion tank;

[0023] (2) Drill round holes on the surface of the anti-corrosion tank, only punch through the outer steel wall without damaging the internal anti-corrosion layer, and the arrangement density of the round holes is 2 pcs / m 2 ;

[0024] (3) Weld the hydraulic quick joint at the round hole, prepare the vacuum machine, and connect the suction pipe of the vacuum machine to the hydraulic quick joint;

[0025] (4) Fill water from the manhole into the anti-corrosion tank, add 2% ethanol halfway, stir, and seal the manhole after filling with water;

[0026] (5) Heat the surface of the anti-corrosion tank to 125°C and keep it there, start the vacuum machine for 40 minutes, and ...

Embodiment 2

[0031] The anti-corrosion tank anti-leakage test method described in the present embodiment comprises the following steps:

[0032] (1) Set the anti-corrosion tank in an environment of 20°C, seal all the branches except the manhole with a cover plate, and set the manhole at the top of the anti-corrosion tank;

[0033] (2) Drill round holes on the surface of the anti-corrosion tank, only punch through the outer steel wall without damaging the internal anti-corrosion layer, and the arrangement density of the round holes is 2 pcs / m 2 ;

[0034] (3) Weld the hydraulic quick joint at the round hole, prepare the vacuum machine, and connect the suction pipe of the vacuum machine to the hydraulic quick joint;

[0035] (4) Fill water from the manhole into the anti-corrosion tank, add 1% ethanol halfway, stir, and seal the manhole after filling with water;

[0036] (5) Heat the surface of the anti-corrosion tank to 120°C and keep it there, start the vacuum machine for 50 minutes, and ...

Abstract

The invention discloses a anti-leakage test method for an anti-corrosion tank, which comprises the following steps: drilling, heating, vacuuming, and testing with an ethanol solution. The concept is ingenious, the operation is simple, and one person can complete the test. The method is special and can accurately judge anti-corrosion. Whether there is a leakage point in the layer, and at the same time adjust the limit stretch of the anti-corrosion layer to make it more suitable for the impact and corrosion of acid-base solution, and extend the service life by 60%.

Description

technical field [0001] The invention belongs to the technical field of petroleum equipment, and in particular relates to an anti-leakage test method for an anti-corrosion tank. Background technique [0002] In petroleum processing enterprises, large-scale anti-corrosion tanks are widely used in all aspects of production. Most of the current anti-corrosion tanks are steel parts, and the internal anti-corrosion coating is rolled or sprayed, and half of them are made of anti-corrosion plastics. Due to the long-term contact with acid and alkali, etc. In contact with corrosive liquids, there must be no leakage points in various parts of the anti-corrosion tank. Therefore, the requirements for anti-corrosion materials and processing technology are very high. Strict testing is required after the anti-corrosion tank is processed. The current test method is simple and has no effect on the characteristics of anti-corrosion plastics. Comprehensive understanding, so accurate and profess...
