Pricing for spiral steel pipes varies due to factors such as specifications, materials, and production processes.
In Cangzhou, the price of DN800 spiral steel pipes is around 190 yuan; the price of flanged spiral steel pipes with internal and external plastic coating is approximately 515 yuan; and the price of DN300 standard spiral steel pipes is around 3 yuan.
Prices listed above are just a partial range; specific prices may vary due to factors such as manufacturers and market conditions.
In the common material of spiral steel pipes, the strength of Q345B is mainly 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 indicates that the yield strength of Q345B is higher than that of Q235B.
Tensile Elongation: The elongation rate for Q345B is ≥19%, while for Q235B it is ≥21%. Although the difference is minimal, it still indicates that Q345B has better plastic deformation capabilities.
In summary, among the common materials for spiral steel pipes, Q345B boasts a high strength.
