What are the factors that affect the service life of the anticorrosive tape?

Release date:2017-11-28 Author: Click:

一分彩1.Effects of mouth and wound repair on polyprene anticorrosive tape

一分彩We know that the welding joints of oil pipelines must be repaired, and the damaged areas must be repaired. The quality of the mouth repair is also crucial to the external corrosion protection of metal pipes. If it is not handled properly, it will directly affect the anticorrosive effect of the entire pipeline. The repair and wound repair of polypropylene anticorrosive tape shall be strictly in accordance with SY / T0414-2007 standard. Anticorrosive tape

2. The impact of engineering construction on anticorrosive tape

一分彩During the construction process, the anti-corrosion layer wound by polypropylene anti-corrosion tape was also very damaged. When we are operating, we need to handle, stack, consign, and hoist the pipelines. At the same time, the buried pipelines need to be ditched and backfilled. If we do not pay attention to the above steps, the corrosion protection layer will be damaged. In these links, it is easy to overlook the backfill damage to the anticorrosive layer. Whether it is manual or mechanical backfill, if the soil or stones are too large during the backfill, the outer anticorrosive layer will be damaged. It must be cleaned and the damage is very small. It is easy to be found, and it is easy to leave a hidden danger of corrosion.

一分彩3.External mechanical force

Natural gas long-distance pipelines are generally buried and have some concealment. The basic construction along the pipeline, including excavation of canals, roads, bridges, and houses, etc. It is easy to cause external forces (especially during mechanical operations) to damage the anti-corrosion layer and pipelines outside the pipeline without knowing the exact location of the pipeline .

In addition, natural disasters should also be taken into account, such as debris flow, landslides, landslides, floods, etc., which will damage the shallow buried pipelines, and the anticorrosive layer of polypropylene anticorrosive tape construction.
