Specification and application of seamless pipe

Seamless pipes have hollow parts and can be used as pipes for conveying fluids, such as pipes for oil, natural gas, gas, water, and some solid materials. Compared with solid steel such as round steel, seamless pipes are lighter in weight when the bending strength is the same, and are widely used in the manufacture of frames and mechanical parts such as economical section steel, oil drills, automobile drive shafts, bicycle frames, and steel scaffolding for construction engineering .
The use of seamless pipes to make ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc., which have been widely manufactured with steel pipes, and are indispensable materials for various conventional weapons. etc. are all made of steel pipes.
1. Structural seamless pipes are used for general structures and mechanical structures.
2. Seamless pipes for fluid transportation are used to transport fluids such as water, oil, and gas.
3. Seamless tubes for low and medium pressure boilers are used to manufacture low and medium pressure boilers of various structures for overheating.
Seamless pipes can be divided into tubular and special-shaped pipes according to the cross-sectional shape. Under the condition of the same circumference, the circular area is larger, so more fluid can be transported with circular pipes. In addition, the ring section is more uniform in force when bearing internal or external radial pressure, so most steel pipes are tubular.
