The cleaning of the pipeline is to dredge the pipeline, clean up the sludge in the pipeline and keep it unblocked for a long time, so as to prevent waterlogging in the city. Water Treatment Pipeline cleaning has become an important work that Drainage Department should pay more attentions. In the drainage pipeline, a large number of sundries and cement sand at the infrastructure construction site will precipitate and deposit, which will cause pipeline blockage. Without the cleaning of pipelines, it will cause excessive flow of sewage, pollute the environment and bring trouble to people’s life.

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.

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.

The main component of Corrosion Probes is a metal sensing element. The element is destroyed after the probe is corroded by the medium in the environment in which it is used. Then its geometry changes. Using Ohm’s law, the resistance of a metal element is related to its geometric size. Finally, by measuring the resistance change of the element before and after corrosion. Combining the time monitoring of the two monitoring readings, we can calculate the corrosion rate (mm/a).

Pipeline damage Pipeline damage is usually the first indication of corrosion problems. However, in many cases. Such signs of pipeline damage will obviously exist for months or years. It’s just that people have been ignoring it. This damage may be minor (in the form of pinhole leakage). It can also be catastrophic. Because whether the water quality is damaged or the pipeline is replaced, it will bring significant economic losses.

After the oil pipeline has been in use for a long time, the inside of the pipeline will be corroded, which requires the use of corrosion test tools to detect the degree of corrosion of the pipeline. So what are the test methods for corrosion coupon ? The editor below will explain in detail the method of corrosion sample test, I hope to help everyone. The details are as follows.
