The reasons for the wide effect of seamless steel pipe are as follows: seamless steel pipe can be produced in combination with other materials, and the output is very large. It can be used to transport substances and accelerate the circulation of substances, such as pipeline transportation. Because it is stronger than ordinary steel tubes, it can also be used to measure the external pressure of liquids. It is a very good pressure measurement tool. It can be used not only to measure the water pressure of ordinary water, but also to provide energy for some mechanical products.


1. Structural seamless steel tube. Mainly used in general structure and mechanical structure.
2. Seamless steel pipe for conveying fluid. It is mainly used for fluid pipeline in conveying engineering and large equipment.
3. Seamless steel tubes for medium and low pressure boilers. It is mainly used for conveying medium and low pressure fluids in industrial boilers and household boilers.
4. Seamless steel tubes for high pressure boilers. It is mainly used for high temperature and high pressure conveying fluid collecting pipes and pipes of boilers in power plants and nuclear power plants.
5. Seamless marine carbon steel and carbon-manganese steel tubes. Mainly used in marine boilers and superheaters I, II pressure pipes.
6. Seamless steel tube is used in high pressure fertilizer equipment. It is mainly used in high temperature and high pressure fluid pipeline of chemical fertilizer equipment.
7. Seamless steel pipes are used for oil cracking. It is mainly used for boilers, heat exchangers and pipes, and for transporting fluid from petroleum smelters.
8. Seamless steel tubes for cylinders. Mainly used in the production of various gases, hydraulic cylinders.
In addition, there are seamless steel pipes for hydraulic props, high-pressure seamless steel pipes for diesel engines, cold-drawn or cold-rolled precision seamless steel pipes, and special-shaped inner diameters for cold-drawn seamless steel pipes, hydraulic cylinders and cylinders.
