Sewage helical steel pipes are used for discharging wastewater, commonly applied in urban drainage systems, wastewater treatment plants, and other facilities requiring wastewater treatment.

Compared to standard steel pipes, it boasts enhanced corrosion and pressure resistance, effectively withstanding the侵蚀 of various corrosive substances in wastewater, thereby extending the pipe's service life. Additionally, the manufacturing process of the spiral steel pipes for sewage discharge is more intricate, usually requiring multiple stages and anti-corrosion treatment to ensure quality and reliability.

When selecting and using drainage spiral steel pipes, various factors must be considered, such as corrosion resistance, pressure resistance, flow rate, and pipe material, as well as installation and maintenance requirements, to ensure long-term stable operation and achieve good drainage and environmental protection effects. Additionally, for use in special environments, more suitable types and specifications of drainage steel pipes should be chosen.

Spiral steel pipes are typically made from low carbon structural steel or low alloy structural steel, such as Q235A, Q235B, 10#, 20#, Q345 (16Mn), L245(B), L290 (X42), L320 (X46), L360 (X52), L390 (X56), L415 (X60), L450 (X65), L485 (X70), L555 (X80), L290NB/MB (X42N/M), L360NB/MB (X52N/M), L390NB/MB (X56N/M), L415NB/MB (X60N/M), L450MB (X65), L485MB (X70), and L555MB (X80). These steels are all suitable for the production of spiral steel pipes.
