Why use carbon steel special-shaped pipes
1.Excellent mechanical properties
Carbon steel profiled pipes have high strength and toughness, can withstand greater pressure and load, and are suitable for load-bearing structures and heavy-duty applications.
2.Good processability
Carbon steel is easy to cut, weld and form, and can be customized in various sizes and shapes according to specific needs to meet different design requirements.
3.Cost-effectiveness
Compared with other materials (such as stainless steel, aluminum alloy, etc.), carbon steel has a lower cost and is suitable for large-scale production and application, which can effectively reduce project costs.
4.Wide range of applications
Carbon steel special-shaped pipes are widely used in many industries such as construction, machinery manufacturing, automobiles, oil and gas, and chemicals, and have strong adaptability.
5.Abrasion resistance and durability
Carbon steel profiled pipes have good wear resistance in certain applications and can be used for a long time in harsh environments.
6.Various surface treatments available
Carbon steel special-shaped pipes can be subjected to a variety of surface treatments such as hot-dip galvanizing, spraying, phosphating, etc. to enhance their corrosion resistance and aesthetics and adapt to different use environments.
7.Lightweight design
The design of the special-shaped tube can optimize the use of materials and achieve lightweight while ensuring strength, which is suitable for the needs of modern engineering.
8.Environmental
Carbon steel material can be recycled, which meets the requirements of sustainable development.
Production process
1.Raw material preparation
Material selection: Select appropriate carbon steel materials according to product requirements. Commonly used ones are Q235, Q345, etc.
Cutting: Cutting large coils or large blocks of steel into suitable sizes for subsequent processing.
2.Molding
Hot Rolling or Cold Rolling: Steel is processed into tubes by hot rolling or cold rolling process. Hot rolling is suitable for large diameter tubes, and cold rolling is suitable for small diameter tubes.
Special-shaped tube forming: Use special forming equipment (such as special-shaped tube forming machine) to process the steel tube into the required special-shaped section (such as rectangular, square, oval, etc.).
3.Welding
Welding process: For special-shaped pipes that need to be welded, use appropriate welding processes (such as arc welding, laser welding, etc.) to weld the edges of the pipes together to ensure welding quality.
Welding inspection: Perform non-destructive testing (such as ultrasonic testing, X-ray testing, etc.) on welded joints to ensure that the welding quality meets the standards.
4.Heat treatment
Annealing treatment: Annealing treatment is performed on the special-shaped pipe after welding to eliminate internal stress and improve the toughness and plasticity of the pipe.
Normalizing: In some cases, normalizing may be necessary to improve the mechanical properties of the material.
5.Surface treatment
Cleaning: Remove oxides, oil stains and impurities from the pipe surface.
Surface treatment: Hot-dip galvanizing, spraying, phosphating and other surface treatments can be performed as required to improve corrosion resistance and aesthetics.
6.Cutting and finished product inspection
Cutting: Cut the special-shaped tube into the length required by the customer.
Finished product inspection: Inspect the finished product in terms of size, appearance, performance, etc. to ensure that it meets customer requirements and relevant standards.
7.Packaging and Shipping
Packaging: The finished products are packaged according to transportation requirements to ensure that they are not damaged during transportation.
Shipping: Qualified products will be shipped to the customer’s designated location.
