Analysis of the effect of corrosion pipeline renovation

(1) Excavate the damaged points with a detection potential gradient greater than 50dB, and replace or repair the steel body according to the degree of corrosion.

(2) For the leakage point of the anticorrosion layer of the pipe perforation, considering that the anticorrosion insulation layer has entered the water and has corrosion conditions, it is replaced locally. The pipe section without perforation and the insulation resistance of the anticorrosion layer is greater than 20008 # m2 shall be retained.

(3) For pipes that are evenly pierced throughout, the perforation density is about 3 times / 100m; the pipe section is not perforated, but the insulation resistance of the anticorrosive layer is less than 20008 # m2; the number of perforations in low-lying areas is more than once / 50m, and the anticorrosive insulation layer is asphalt All pipes of perlite and plastic perlite must be replaced.

The accuracy rate of the pipeline reconstruction amount determined by the inspection and investigation is 32% of the single inspection.

Adjust the path of the tested pipeline, adjust a total of 11 oil ring paths, shorten the distance of 4.6km, and save 70 @ 104 yuan. Due to the targeted maintenance and reconstruction, the investment has been greatly reduced. For example, the Fang 6 external pipeline has a total length of 6.4km. After the inspection, it is determined to repair 87 sections, with a length of 0.45km. A total investment of 6.2@104 yuan is required. In 2002, the pipeline was tested for 440km, of which the reported pipeline corrosion amount was 230km, the test block (Chengdong, Dingwang Station) was 150km, and the external oil pipeline was 60km (Feiyantan, Futai Station). The maintenance amount was 8km, and all or part of the replacement 52km, with an investment of 1090 @ 104 yuan.

At the same time, the maintenance of the pipelines including 13 oil transfer stations in question, the comprehensive recovery of the pipelines of the two oil transfer stations, and the external pipelines of the two joint stations are equivalent to 1000km pipelines, with an average investment of 1.09@104yuan/km. According to the above According to the analysis, the existing pipelines of Hekou Oil Production Plant were renovated in a partial maintenance mode, designed to prolong the service life by 16 years, with 8 inspections and repairs, and inspections and repairs every other year. The annual maintenance is 0.45km, with a total investment of 49.6@104 yuan. If the whole replacement is done at one time, the design life is 15 years, and the investment is 161.5@104 yuan.

Pipeline inspection and maintenance measures can accurately locate the location of pipeline corrosion and corrosion hazards through inspection. After optimized design, targeted maintenance and reconstruction can be carried out to reduce blindness. Simultaneous inspection and repair of pipelines Establish a pipeline inspection and maintenance mechanism to inspect and repair parts with light corrosion, and include pipelines with severe corrosion in the annual renovation plan.
