The pigging system consists of elastic projectiles (“pigs”) with a diameter slightly larger than the pipeline carrying the liquid. The pigging process introduces a pig into the pipeline. (usually automatically). and push it through the pipe. A pig is pushed through a pipeline by pressurizing the piping system behind it. Compressed air, carbon dioxide, nitrogen, freshwater or even the next product (depending on the application) provide the pressure. The liquid residue in the pipeline is recovered. Instead of flushing down drains, waste disposal, or collection areas: Propelled by pipe cleaners. and forced into the fill or storage tank at the destination, or returned to the source. Processing then continues with the remaining product.

At present, there are many methods for determining the corrosion rate, such as gravimetric method, volume method, polarization curve method (polarization resistance method) and so on. Gravimetric method is a classic method, which is suitable for laboratory and field coupons. It is one of the most reliable methods for determining the corrosion rate of metals. It can be used to detect the corrosion resistance of materials, select corrosive agents, and check the anti-corrosion effect when changing process conditions.

Pipeline oil leakage is a serious risk during pigging. Although there are various reasons for pipeline oil leakage. But generally speaking, it mainly includes the following two aspects: First, after long-term corrosion of the pipe body, there are thin parts in the severely corroded parts. The thin part of pipe wall may be broken during ball passing. There is also a risk of oil leakage from the pipeline.

Removal Tool usually works with Corrosion coupons. Corrosion coupons are necessary equipment to detect or evaluate the corrosion status of the pipeline system. It can accurately display the corrosion situation inside the pipeline system and assist in the maintenance of the pipeline.

Pig Scraper jamming is a serious problem that may occur during pigging. If it is not serious, it will cause the interruption of the oil transportation process. In severe cases, it may cause an abnormal increase in pipeline pressure. This may even lead to serious problems such as pipe leakage. There are various reasons for pig jamming.

Having established the usefulness of industrial process pipeline cleaning, it is equally important to know when to implement pipeline cleaning solutions. There are various points in the lifetime of a pipeline where pipeline cleaning solutions must be applied.

Classification of oil pipelines in pipeline cleaning has two categories: The first is the internal oil pipeline of the enterprise. For example, the gathering and transmission pipeline connecting the oil well with the metering station or the combined station in the oil field. Or pipelines inside refineries and oil depots. Its length is generally short, and it is not an independent business system. The other is a long-distance oil pipeline. For example, the pipeline transporting qualified crude oil from the oil field to the refinery or railway transfer station. Its pipe diameter is generally large, and there are various auxiliary projects. This kind of pipeline is an independent system. They have another name “trunk pipelines”. According to the type of medium transported, oil pipelines include crude oil pipelines and product oil pipelines. To ensure the service life of the pipeline, both of them need pipeline cleaning.
