With the development of modern industry, pipelines, as an important tool for fluid transportation, are constantly being updated and improved. Among them, seamless steel pipelines have become the number one choice in the pipeline industry nowadays because of its many advantages such as high strength, resistance, high temperature:pressure resistance and corrosion resistance. In this paper, the durability and reliability of seamless steel pipelines will be discussed in depth.

I. Durability of seamless steel piping

1. Selection of material

The material of seamless steel pipe is the basis of its superior performance, and high quality steel can better ensure its durability. Currently, there is a wide variety of steel materials available in the market, and some low-quality steel materials are used by some unscrupulous manufacturers to manufacture seamless steel pipes due to their low cost and easy availability. These low-quality steels are prone to lose their original strength and toughness during the process of high pressure and high temperature, which affects the durability of the pipes. Therefore, when choosing the material of seamless steel pipe, it is necessary to choose high-quality steel, such as 20#, 35#, 45#, etc., to ensure the durability of the pipe.

2. Requirements for surface treatment

In addition to the choice of material, the surface treatment of seamless steel pipe is also very critical. The service life of any pipe will be affected by the external environment, and the problems of rust, corrosion and oxidation on the surface are important factors affecting the service life of the pipe. Therefore, when manufacturing seamless steel pipe, its surface must be treated to prevent problems such as rust and corrosion. Commonly used methods include painting, electroplating, hot-dip galvanizing, etc. These surface treatment methods can effectively improve the durability of seamless steel pipe.

Second, the reliability of seamless steel pipeline

The reliability of seamless steel piping refers to the fact that the piping will not have problems such as leakage or breakage during the use of the piping, thus ensuring the safe transportation of fluids. The reliability of seamless steel piping is affected by factors such as manufacturing standards, welding quality, and piping installation, in addition to the material and surface treatment mentioned above.

1. Strict requirements of manufacturing standards

The manufacturing standard of seamless steel pipe is the basis of pipe reliability. Under the specification of national standards, the production of seamless steel pipe must meet certain size error, wall thickness error, material composition, chemical composition and other requirements. Especially in the wall thickness of seamless steel pipe, the thickness should be controlled according to the actual needs to ensure that the pipe will not be deformed or cracked when it is subjected to high pressure and high temperature.

2. The importance of welding quality

In the production and installation of pipelines, welding is inevitable. High-quality welding can ensure the reliability of the pipeline, while low-quality welding is one of the main causes of pipeline leakage, fracture and other problems. Therefore, in the production process of seamless steel pipe, jointing technology and welding quality have received more and more attention. High-quality welding can ensure the reliability of the pipeline, to avoid the leakage of the pipeline, fracture and other potential safety hazards

3. Pipe installation requirements

In addition to manufacturing standards and welding quality, pipe installation is also an important factor affecting the reliability of the pipeline. In the installation process of seamless steel pipeline, a series of measures need to be taken to ensure that the pipeline is not damaged, bending or twisting and other situations. Particularly at the pipe connection, suitable connection methods and sealing materials must be used to ensure that the pipe is immersed in leakage, otherwise the pipe will be prone to leakage problems.

Overall, seamless steel piping is a quality choice in the piping industry today. Its durability and reliability are important factors that directly affect the service life and safety of the pipeline. In order to ensure the quality and reliability of the pipeline, strict measures must be taken in the selection of materials, surface treatment, manufacturing standards, welding quality and pipeline installation to ensure that the seamless steel pipeline does not have any safety hazards in use!
