The API 5L X52 material spiral steel pipe, made from high-quality carbon structural steel, serves primarily for transporting fluids such as petroleum and natural gas. It boasts thick walls, substantial weight, and high pressure resistance. The manufacturing process involves perforating, rolling, sizing, straightening, cutting, welding, and hydrostatic testing. These treatments render the pipe surface smooth, free from bubbles, and scars, while imparting high strength and corrosion resistance.
High Pressure Resistance: The API 5L X52 spiral steel pipe exhibits exceptional pressure resistance, ensuring smooth fluid flow within the pipeline while maintaining high safety levels.
Strong Corrosion Resistance: Fashioned from high-quality carbon structural steel and coated with an anti-corrosive layer post-treatment, its surface effectively prevents internal pipeline corrosion and rust.
Convenient Connection: The pipe offers diverse connection methods such as welding and flange connection, ensuring convenience, speed, and maintaining pipeline sealing and safety.
Low Fluid Resistance: The spiral design minimizes fluid resistance within the pipeline, thereby reducing energy loss during fluid transportation.
Easy Installation: Installation is straightforward, supporting various methods including bracket fixation and hoisting, while providing flexibility in pipeline layout to adapt to different terrains and environmental conditions.
III. Application Range
Widely used in fluid transportation fields including petroleum extraction, natural gas transmission, and chemical industries, the API 5L X52 spiral steel pipe also finds application in water conservancy projects, urban water supply, and drainage systems.
IV.API 5L X52 spiral line pipe Manufacturing Process
Perforation: Using a punching machine, steel plates are perforated to form cylindrical pipe blanks.
Rolling: Perforated pipe blanks undergo rolling to achieve a smooth surface, free from bubbles and scars.
Sizing: Sizing machines ensure precise diameter control to meet specified requirements.
Straightening: Treatment ensures pipes meet required bending curvature after rolling.
Cutting: Straightened pipes are cut to specified lengths as per requirements.
Welding: Welding or flange connection methods join cut pipes.
Hydrostatic Testing: Welded or connected pipes undergo hydrostatic testing to inspect sealing performance and pressure resistance.
