There are numerous types and specifications of spiral steel pipes. The following is just a partial list of available specifications:
Diameters (DN) range from 20 mm (DN20) to 2000 mm (DN2000), with common diameters including: DN50, DN100, DN150, DN200, DN250, DN300, DN350, DN400, DN450, DN500, DN600, DN700, DN800, DN900, DN1000, DN1200, DN1400, DN1600, DN1800, and DN2000.
The above data is for reference only. If needed, it is recommended to consult the manufacturers of spiral steel pipes.
In common spiral steel pipe materials, the strength of Q345B is primarily reflected in the following aspects:
Tensile Strength: The tensile strength of Q345B is 370~500 N/mm², whereas Q235B's tensile strength is only 230~340 N/mm². This indicates that Q345B has a higher tensile strength than Q235B.
Yield Strength: The yield strength of Q345B is ≥320 MPa, while Q235B's yield strength is ≥195 MPa. This means Q345B has a higher yield strength than Q235B.
Tensile elongation: The elongation rate of Q345B is ≥19%, while that of Q235B is ≥21%. Although the difference in elongation rate is not significant, it still indicates that Q345B has better plastic deformation capability.
In summary, among the common materials for spiral steel pipes, Q345B has the strength.
