Large Diameter Spiral Steel Pipe for Sewer & Drainage Projects
For sewage/drainage projects with high flow rates, long distances, and the need to withstand external or internal pressure, spiral steel pipes provide higher strength, longer single length, and more reliable connection performance than traditional pipes. Get a Quote / Check Specifications
Why Use Spiral Steel Pipe for Sewer & Drainage Systems?
High pressure bearing capacity: suitable for Sewer Force Mains (pressure sewage pipes), which is a scenario that gravity flow plastic pipes cannot handle.
Long distance laying: Single spiral steel pipes can reach up to 12 meters or even longer, reducing joints and lowering the risk of leakage (compared to concrete pipes).
Anti foundation settlement: Steel has better ductility than concrete and cast iron, and performs well in drainage engineering in earthquake zones or soft soil foundations.
Customized anti-corrosion: The interior can be lined with epoxy resin or cement mortar, and the exterior can be made with 3PE, perfectly responding to the chemical corrosion of sewage.
Applications of Spiral Steel Pipe in Drainage Infrastructure
Sewage Treatment Plants
Used for sludge pipes, process pipes, and inlet/outlet pipes in the factory area.
Stormwater Culverts & Drainage
Large caliber spiral corrugated pipes or steel pipes are used for water culverts under roads and bridges.
Marine Outfall & River Crossing
Steel pipes can be welded into a whole section and dragged into water, with excellent sealing performance.

FAQs about Steel Pipe for Sewer
Q1： Can steel pipe be used for sewer lines?
A： Yes, especially for large diameter mains, force mains, and outfall structures where strength is required.
Q2： How long does steel sewer pipe last?
A： With proper coating (FBE/3PE) and cathodic protection, lifespan can exceed 50 years.
Q3： What is the difference between SSAW and LSAW for drainage?
A： SSAW is more cost-effective for large diameters and thinner walls, making it ideal for low-pressure drainage.
