Spiral pipes are mainly used for oil and natural gas pipelines, and their specifications are expressed by outer diameter * wall thickness. Spiral pipes are single-sided welded and double-sided welded. Welded pipes should ensure that the water pressure test, tensile strength of the weld and cold bending performance meet the requirements.
Industry uses and main models of spiral steel pipes
Spiral steel pipes are widely used in many industries due to their excellent performance and wide adaptability. The following are its main application areas:
Oil and gas industry:
Used to transport oil, natural gas and other media, especially in long-distance transmission pipelines.
Hydraulic and hydropower engineering:
Applicable to the construction of hydropower stations in large-scale water conservancy projects, such as water pipelines.
Chemical industry:
Corrosion-resistant piping systems required in the chemical production process, used to transport chemicals and other corrosive substances.
Building and infrastructure:
Building structure support, bridge construction, urban rail transit projects, etc., as one of the important
Agricultural irrigation:
The main road of the farmland irrigation system is laid to ensure the effective distribution of water resources.
Marine engineering:
The basic structural parts of the submarine oil and gas extraction platform and the pile foundation materials of the offshore wind farm.
Main models
Spiral steel pipes have different models and specifications according to different application scenarios and technical requirements. Common models include but are not limited to the following:
Q235B: Ordinary carbon structural steel, widely used in general construction engineering and manufacturing.
20#: Low alloy high strength structural steel, suitable for applications requiring higher strength.
L245 / L415: Suitable for fluid transportation under high pressure environment, such as oil and gas pipelines.
Q345B: Low alloy high strength structural steel, with good weldability and cold forming performance, commonly used in bridges, towers and other fields.
X52 / X60 / X70 / X80: High-grade pipeline steel, designed for oil and gas transportation under extreme conditions, capable of withstanding higher pressures and temperatures.
SSAW (Submerged Arc Welded): Double-sided submerged arc welded steel pipe, suitable for large diameter thick wall pipelines, commonly used in the field of energy transmission.
