In what scenarios is LSAW pipe primarily used?
LSAW Pipe is mainly used in large-diameter, high-strength pipeline and structural engineering projects, particularly where strict requirements for dimensional accuracy, weld quality, and pressure resistance apply
Main Applications of LSAW Pipe
| Oil & Gas Transmission | For long-distance transportation of crude oil, natural gas, and refined petroleum products. |
| Water Transmission | Used in municipal water supply, drinking water, seawater, irrigation, and large-scale water diversion projects. |
| Structural Engineering | Applied in bridges, building structures, offshore platforms, and large steel structures. |
| Industrial Piping | Used for transporting fluids in power plants, chemical plants, refineries, and other industrial facilities. |
| Offshore & Marine Engineering | Suitable for offshore pipelines, marine structures, and subsea engineering projects. |
| Pile & Foundation Projects | Used as large-diameter steel piles for bridges, ports, buildings, and other heavy infrastructure. |
| District Heating & Utility Pipelines | Applied in large-scale heating, cooling, and utility transmission systems. |
Anti-Corrosion Surface Treatments for LSAW Pipe
| 3PE Coating (Three-Layer Polyethylene) | Widely used for buried oil, gas, and water transmission pipelines, providing excellent resistance to corrosion, moisture, and soil environments. |
| FBE Coating (Fusion Bonded Epoxy) | Suitable for oil & gas pipelines, water pipelines, and harsh environments, offering strong adhesion and chemical resistance. |
| 3PP Coating (Three-Layer Polypropylene) | Designed for higher-temperature pipeline applications where greater thermal resistance is required. |
| Internal Epoxy Lining | Applied to the internal surface of water and fluid transportation pipes to prevent internal corrosion and reduce friction. |
LSAW Pipe End Treatments
| Plain Ends (PE) | Suitable for welding and general pipeline applications. |
| Beveled Ends (BE) | Commonly used for butt welding; the bevel angle and root face can be manufactured according to the applicable standard. |
| Flanged Ends | Used where detachable connections are required, particularly in water treatment, industrial piping, and equipment connections. |
| Custom End Preparation |
Special end configurations can be provided according to project drawings, connection methods, and customer requirements. |
