) Song Dynasty Seamless Steel Pipe Implementation Standard
Song Dynasty
Structural seamless pipes (/) are seamless steel pipes used for general structures and mechanical structures.
Seamless steel pipes for fluid transportation (/) are general seamless steel pipes used to transport fluids such as water, oil, and gas.
Seamless steel pipes for low and medium pressure boilers () are high-quality carbon used to manufacture superheated steam pipes and boiling water pipes for low and medium pressure boilers of various structures, as well as superheated steam pipes and arch brick pipes for locomotive boilers. Plain structural steel hot-rolled and cold-drawn (rolled) seamless steel pipes.
Seamless steel pipes for high-pressure boilers (
) are high-quality carbon steel, alloy steel and stainless steel heat-resistant for the heating surface of water tube boilers with high pressures and above. Steel seamless steel pipe.
High-pressure seamless steel pipes for fertilizer equipment () are high-quality carbon structural steel and alloy steel seamless steel pipes suitable for chemical equipment and pipelines with working temperatures of ~°C and working pressures of ~°C.
Seamless steel pipes for petroleum cracking () are seamless steel pipes suitable for furnace tubes, heat exchangers and pipelines in petroleum refineries.
) 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
Song Dynasty.
) Purpose
The expression method of seamless steel pipe is outer diameter*wall thickness.
Calculation formula
Seamless steel pipe weight per meter.*
Symbol meaning outer diameter wall thickness
Seamless steel pipe price per meter (outer diameter wall thickness)*wall thickness*.* Price per kilogram
