 Welding problems are sometimes encountered during the installation of carbon steel tubes. So, how to weld tubes? What should we pay attention to when welding carbon steel tubes? 1. Gas welding Gas welding can be used for welding, which is to mix combustible gas and combustion-supporting gas together, use it as the heat source of the flame, and then melt and weld the pipes together. 2. Arc welding Arc welding can also be used, that is, arc welding is used as the welding method. A heat source that connects the pipes together. This welding method is often used in industrial production. In addition to the above two methods, the welded pipeline can also use contact welding, and the specific method to be welded depends on the material and requirements of the pipeline. Steel consists of iron and carbon with small amounts of miscellaneous metals, such as manganese, chromium, silicon, vanadium, and nickel. Low carbon steel contains only 0.3 percent carbon, making it incredibly easy to weld...

Because oil and gas pipelines are buried underground for a long time, they are very prone to corrosion problems due to soil, moisture and other factors. At present, pipeline corrosion in the petrochemical industry is mainly divided into two types: 1) External corrosion, the so-called external corrosion specifically refers to the corrosion caused by the connection between the metal material of the pipeline and the corrosive medium in the external environment.At the same time, since some pipelines have an insulation layer outside, moisture may accumulate under the insulation layer due to other factors (sometimes due to the high temperature of the medium in the pipe, the external moisture may be heated) to cause corrosion. 2) Internal corrosion, the so-called internal corrosion specifically refers to the corrosion of the inner layer of the pipeline. The types of internal corrosion that occur are different depending on the properties of the fluid in the pipeline. Including acid corrosion, ...
