Spiral Steel Pipes: Essential for Oil, Gas & Infrastructure Projects
Spiral Steel Pipes, characterized by their outer diameter × wall thickness specifications, are critical components in oil, gas, and industrial piping systems. Manufactured as single-sided or double-sided welded pipes, they undergo rigorous hydrostatic testing, weld strength checks, and cold bending evaluations to ensure reliability.
Key Applications of Spiral Steel Pipes
-
Oil & Gas Industry
-
Primary use: Long-distance pipelines for crude oil and natural gas transmission.
-
-
Hydraulic & Hydroelectric Projects
-
Essential for water pipelines in dams and hydropower stations.
-
-
Chemical Industry
-
Transport corrosive chemicals with specialized corrosion-resistant variants.
-
-
Construction & Infrastructure
-
Used in bridges, urban rail transit, and structural supports for high-load durability.
-
-
Agricultural Irrigation
-
Distribute water efficiently in large-scale farmland systems.
-
-
Marine Engineering
-
Deployed in offshore oil platforms, wind farm foundations, and subsea pipelines.
