Product Advantages

High Strength: The steel structure provides excellent mechanical strength and pressure-bearing capacity, making the pipe suitable for demanding pipeline applications.

Large Diameter Capability: Spiral forming technology enables efficient production of large-diameter pipes, supporting high-volume fluid transportation.

Cost-Effective Production: Using steel coils and continuous spiral welding optimizes material utilization and improves manufacturing efficiency.

Reliable Welded Joint: Advanced automatic welding technology delivers consistent, strong spiral seams for reliable in-service performance.

Flexible Specifications: Spiral steel pipes are available in a range of outside diameters, wall thicknesses, steel grades, and lengths.

Good Structural Performance: Strength and rigidity make them suitable not only for fluid transportation, but also for structural and foundation applications.

Easy to Customize: Pipe dimensions, surface treatment, coating, and end configurations can be customized to meet project requirements.

Product Features

Spiral Steel Pipe is manufactured using a spiral forming process. Steel coils are continuously uncoiled, leveled, formed into a cylindrical shape at a specified angle, and welded along the spiral seam. This production method enables the manufacture of large-diameter pipes while maintaining consistent dimensional accuracy and welding quality.

Depending on the application, the pipe may be supplied with different surface finishes and corrosion protection systems, such as external or internal coatings. Ends can also be processed as plain ends, beveled ends, or other configurations required for installation. Quality inspections may include dimensional checks, visual inspection, weld inspection, hydrostatic testing, and other tests in accordance with applicable standards and project requirements.

Product Applications

Spiral Steel Pipe is widely used across industries and infrastructure projects, including:

Water Supply Pipelines: Suitable for municipal, industrial, and long-distance water transmission systems.

Oil and Gas Transportation: Used for pipelines transporting crude oil, natural gas, and other petroleum products.

Drainage Systems: Commonly used in municipal drainage, wastewater, and stormwater transportation projects.

Structural Engineering: Used as structural members in bridges, buildings, towers, and other construction projects.

Pile Foundations: Large-diameter spiral steel pipes can be used as foundation piles for buildings, bridges, ports, and other heavy structures.

Industrial Pipelines: Suitable for transporting various liquids and gases in industrial facilities.

Heating and Energy Projects: Used in district heating networks and other energy-related pipeline systems.
