Use of seamless steel tube

Oct. 23, 2019

Seamless steel pipes are made of a single piece of metal with no seams on the surface. According to the production method, seamless tubes are divided into hot rolled tubes, cold rolled tubes, cold drawn tubes, extrusion tubes, jacking tubes, etc. According to the shape of section, seamless steel tube is divided into circular and special-shaped tube, special-shaped tube has square, oval, triangle, hexagon, melon seed shape, star, with a variety of complex shapes of wing tube. The maximum diameter is 650mm, and the minimum diameter is 0.3mm. Depending on the use, there are thick wall seamless steel pipe and thin - walled tubes.

Seamless steel tubes are widely used. General purpose seamless steel tubes are rolled from ordinary carbon structural steel, low alloy structural steel, or alloy structural steel. They produce the most. A pipe or structural part used primarily for conveying fluid . There are three types of supply according to different uses: (1) supplied according to chemical composition and mechanical properties; (2) supply according to mechanical properties; (3) supply according to hydraulic test. Steel tubes supplied according to class a and class b, if used to withstand liquid pressure, shall also be hydraulically tested. There are many kinds of seamless tubes for boiler, chemical power, geology and petroleum.

Seamless fluid steel tube has a hollow section, a large number of fluid used for conveying pipelines, such as oil, natural gas, gas, water and some solid materials pipelines. Compared with round steel and other solid steel. It is a kind of economical section steel with the same bending strength and torsional strength. It is widely used in manufacturing structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction, etc., to make ring parts with steel pipe, which can improve material utilization rate, simplify manufacturing process and save material and processing time. Steel pipe has been widely used in manufacturing.

Used in steel pipe manufacturing ring parts, can improve material utilization rate, simplify manufacturing process, save material and processing time, such as rolling bearing ring, jack sleeve, etc., has been widely used in steel pipe manufacturing. Steel tubes can be divided into circular tubes and special-shaped tubes according to the shape of cross sectional area. Since the circular area is the largest given the same circumference, more fluid can be transported through the circular tube. In addition, when the circular section is subjected to internal or external radial pressure, the force is more uniform, therefore, the vast majority of steel tubes are circular tubes. However, circular pipe also has certain limitations, such as in the plane bending conditions, circular pipe is not as strong as square, rectangular pipe bending strength, some agricultural machinery framework, steel and wood furniture, commonly used square, rectangular pipe. Special-shaped steel tubes with other section shapes are required for different purposes.
