With more industries, the demand for steel pipes is constantly increasing. This has strongly promoted the development of steel pipes in terms of variety, yield and quality. This gives all the industries that will use the steel pipe, more options. Different industries have certain differences in the choice of steel pipes. After all, different industries, the performance of steel pipes required, and the environment in which steel pipes are used cannot be the same. This gives all steel pipe types a good market.
However, in recent years, such a trend has been broken by a new steel pipe, which is a seamless steel pipe. Nowadays, seamless steel pipe has become the most popular pipe and has been chosen by many industries. The reason why we choose seamless steel pipe is because it is more adaptable to complex environments.
Adaptability to the environment of use
For example, the general seam steel pipe, if long-term, is in a humid environment. Then the pipe is very easy, it will start to rust, and once the pipe starts to rust, all aspects of performance will be worse than before. If in the transportation industry, rusty pipes will also affect the quality of tap water, which will affect everyone’s health.
If you are using seamless steel pipes, there is no such worry at all. Because it has excellent antioxidant treatment. The most important thing is that the seamless steel pipe is a good way to isolate the impact of the wet environment on the pipeline. This allows it to withstand wind and rain even when exposed to the outdoors, but the pipeline itself does not change.
Moreover, seamless steel pipes are more widely used than seamed steel pipes. The general-purpose seamless steel pipe is rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, and has the largest output, and is mainly used as a pipe or structural component for conveying fluid.
Types of supply
According to the use, there are three types of supply: a, supply according to chemical composition and mechanical properties; b, supply according to mechanical properties; c, supply according to water pressure test. Steel pipes supplied in categories a and b, if used to withstand liquid pressure, are also subjected to hydrostatic testing. Special-purpose seamless pipes are used for boilers, chemical power, geological and petroleum.
Seamless steel tubes have hollow sections and are used in large quantities as pipelines for transporting fluids, such as pipelines for transporting petroleum, natural gas, gas, water and certain solid materials, which are superior to erw steel pipes. Compared with solid steel such as round steel, the steel pipe has a lighter weight when it has the same bending and torsional strength, and is an economical section steel. Widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automotive drive shafts, bicycle frames and steel scaffolding used in construction, such as steel scaffolding, to make ring parts, improve material utilization, simplify manufacturing processes, save materials and processing In working hours, steel pipes have been widely used for manufacturing.
