) Songti seamless steel pipe
Songti is a long steel material with a hollow section and no seams around it.
Widely used to manufacture structural parts and mechanical parts , such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction, etc., using steel pipes to make ring-shaped parts can improve material utilization, simplify the manufacturing process, save materials and processing hours, and has been widely used in manufacturing.
Song style steel pipes can be divided into round tubes and special-shaped pipes according to different cross-sectional area shapes
Song style steel pipes.
Because under the condition that the circumferences are equal
, the circle area
of Song font is larger than
Song font
, and circular tubes can transport more fluid
Song Dynasty.
Song Dynasty In addition
, the ring cross-section is relatively evenly stressed when it bears internal or external radial pressure. Therefore, the vast majority of steel pipes are round pipes
