Production Process
Billet Preparation: High-quality carbon steel billets are heated to a high temperature.
Extrusion: The billet is extruded through a die to form a hollow shell.
Cold Drawing: The pipe is further processed through cold drawing to achieve precise dimensions and surface finish.
Heat Treatment: Normalizing or annealing is performed to enhance mechanical properties.
Inspection: The pipes undergo rigorous testing, including ultrasonic and hydrostatic tests, to ensure quality.
Applications
Oil and gas exploration and refining
Power generation (boiler and heat exchanger tubes)
High-pressure hydraulic systems
Structural and mechanical applications
Advantages
High Strength: No welded seams, making them stronger and more reliable for high-pressure applications.
Uniformity: Consistent wall thickness and smooth interior surface.
High-Temperature Resistance: Suitable for extreme temperature conditions.
