Production Process
1. Billet Preparation
High-quality carbon steel billets are heated to a high temperature to prepare for the forming process.
2. Extrusion
The heated billet is extruded through a precision die to form a hollow shell with the desired outer diameter.
3. Cold Drawing
The pipe is further processed through cold drawing to achieve precise dimensions and superior surface finish.
4. Heat Treatment
Normalizing or annealing is performed to enhance mechanical properties and relieve internal stresses.
5. Quality Inspection
The pipes undergo rigorous testing, including ultrasonic and hydrostatic tests, to ensure quality compliance.
Applications
Oil and Gas Industry
Widely used in oil and gas exploration, drilling operations, and refining processes where high pressure and corrosion resistance are critical.
Power Generation
Essential for boiler tubes and heat exchanger applications in power plants, providing reliable performance under extreme temperatures.
High-Pressure Hydraulic Systems
Perfect for hydraulic cylinders, high-pressure lines, and precision machinery requiring consistent wall thickness and strength.
Structural and Mechanical Applications
Used in construction, automotive, and mechanical engineering where structural integrity and precise tolerances are required.
Advantages
Superior Strength
Seamless construction eliminates welded joints, resulting in higher strength and reliability for high-pressure applications. The uniform structure provides consistent performance throughout the pipe length.
Dimensional Uniformity
Cold drawing process ensures consistent wall thickness and smooth interior surface, providing optimal flow characteristics and reduced pressure drop in fluid systems.
High-Temperature Resistance
Excellent thermal stability makes these pipes suitable for extreme temperature conditions in power generation, chemical processing, and other demanding industrial environments.
