Introduction
Seamless steel tubes have many advantages, such as excellent corrosion resistance, high temperature resistance, high tensile strength and durability, which make them a preferred choice for many applications including the production of gas cylinders used in the medical and industrial sectors.
This article outlines the application of seamless steel tubes in the production of gas cylinders as used in the medical and industrial sectors, discussing their advantages and the various steps involved in the process.
Working principle
The production of gas cylinders using seamless steel tubes involves several stages, including rolling, pipe welding, heating, cooling and testing.
Rolling
Steel tubes used for gas cylinders are typically made using the rolling process, which involves passing a metal through a series of rollers in order to produce a tube of desired size and shape. During the rolling process, the finished tubes are subjected to a number of tests to ensure that they meet certain industry standards.
Pipe welding
Once the seamless steel tubes have been produced, pipe welding is used to join them together and create a cylindrical shape. This process involves using a welding machine to heat the ends of the tubes to high temperatures and then join them together. It requires a great deal of skill and precision, as any imperfections or irregularities in the welded joint can cause the cylinder to fail safety tests.
Heating and cooling
Once the welding is complete, the gas cylinder is heated to a temperature of around 400 deg C. This serves to seal the welded joint and also dissolve any impurities present in the metal. After the temperature has been reached, the cylinder is then cooled, allowing it to eventually return to room temperature.
Testing
The last step of the process involves subjecting the cylinder to various tests, such as compression and tensile strength tests, in order to ensure that it meets the industry safety standards. This is an essential part of the process and helps to ensure that cylinders produced using seamless steel tubes meet all necessary requirements.
Conclusion
The production of gas cylinders using seamless steel tubes is a complex process that requires a great deal of skill and precision. However, it offers several key advantages, such as excellent corrosion resistance, high temperature resistance and excellent tensile strength. By undergoing rigorous safety tests, gas cylinders produced from seamless steel tubes can also be used in the medical and industrial sectors with a high degree of reliability.
