Enhanced pressure-bearing capacity: Withstanding high pressure, it’s ideal for transporting liquids and gases.
Effective corrosion resistance: Coated with anti-corrosive materials, it prevents oxidation.
Streamlined construction: Longer length and larger diameter reduce welding and connection processes, cutting project costs.
Improved reliability: Crafted from high-strength steel, ensuring durability for long-term operations, thus reducing maintenance.
Versatile application: Suitable for various media like oil, natural gas, and water, making it highly adaptable.
In various industries, api 5l standard spiral steel pipes find utility in:
Petroleum, natural gas, and chemical transmission pipelines.
Water conservancy, heating, and steam supply systems.
Construction, bridges, highways, airports, and docks.
Line pipe spiral steel pipes are primarily utilized for long-distance transportation of non-corrosive media, including:
Oil and gas pipelines.
Hydraulic and municipal engineering projects.
Structural applications.
Construction of gas spiral steel pipes follows these steps:
Pipeline layout: Plan direction, diameter, and elbows to facilitate welding and connection.
Material preparation: Gather necessary pipes, fittings, valves, and sealing materials.
Pipe welding: Cut, bevel, and butt large-diameter pipes before arc or submerged arc welding.
Pipe connection: Utilize threaded, flange, or socket connections.
Pipeline testing: Perform static pressure, leakage, and opening tests to ensure safety.
Anti-corrosion treatment: Apply internal and external coatings for longevity and safety.
Adherence to safety regulations and procedures is paramount throughout the construction process to ensure project quality and safety.
