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.

Oil is extracted from the underground to the ground and transported to a large refinery to refine the crude oil into the raw materials and the oil which we need. In the process of transporting crude oil, the main transportation tools are divided into two kinds. One is to transport crude oil by vehicle mounted oil tank truck. In this case, the cost is very high. Generally, crude oil is transported by oil 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.

In Shenyang EMT Piping Technology Co., Ltd,, on Dec. 6, the staff sang the familiar birthday song to send sincere wishes to several "birthday stars" wearing birthday hats.

This is China Shenyang EMT Piping Technology Co., Ltd, We are a professional manufacturer of pipeline cleaning products

Description Polyurethane disc is the main component of pigs. Based on years of experience in production and on-site actual pigging operations. So we draw on the advanced technology of foreign pipeline companies to continuously improve the outer dimensions and materials of polyurethane discs to achieve optimal cleaning.

Pigs for Pipeline Cleaning Pigs are supporting equipment for pipeline cleaning. Pigs for Pipeline Cleaning are driven by gas, liquid, or pipeline transmission medium. It can carry other auxiliary equipment to complete various complex pipeline operations. Without pigging technology, it is impossible to carry out pipeline construction and operation. Only pigs can accomplish a lot of work economically. Therefore, pipeline technology and pigging technology are inseparable.

The Working Process of The Pig is As Follows: Stage 1: Product transmission. Stage 2: The pig is pushed into the product pipeline by compressed air. Stage 3: Pig return.
