Shaped/Profile Carbon Steel Tube
Shaped or profile carbon steel tubes are specialized steel tubes that have been manufactured into various cross-sectional shapes other than the standard circular form. These tubes can be square, rectangular, oval, or even more complex custom profiles, depending on the application requirements.
Shaped/Profile Carbon Steel Tube
what is Shaped Steel Tube？
A Shaped Steel Tube, also known as a Hollow Structural Section (HSS), is a metal profile with a hollow cross-section that comes in various shapes such as rectangular, square, circular, and elliptical. Typically made from steel, these tubes offer high strength-to-weight ratios, making them ideal for structural applications in construction, manufacturing, automotive, and furniture industries. They are valued for their durability, versatility, and aesthetic appeal, often used in building frameworks, machinery, vehicle frames, and modern furniture designs.
What is the most cost-effective metal material for manufacturing Shaped Steel Tube？
Carbon steel is a cost-effective material for manufacturing shaped steel tubes due to its affordability, versatility, and mechanical properties. It primarily consists of iron and carbon, with varying carbon content influencing its strength and ductility. Low carbon steel, or mild steel, is particularly suitable for shaped tubes due to its ease of forming. While carbon steel offers good tensile strength and is widely available, it is prone to rust and requires protective coatings for enhanced durability in corrosive environments. Despite this, its widespread use in construction, automotive, and machinery industries underscores its economic and practical advantages.
Products Process
I. Raw Material Preparation and Pretreatment
Billet Selection
Select carbon steel round bars or rolled rods that meet performance requirements, ensuring material composition and dimensions are compatible with subsequent processing equipment.
Surface Treatment
Remove rust from corroded round steel using wire brushes or coarse sandpaper to eliminate surface oxidation layers, exposing the metallic base. Apply anti-rust primer if necessary to extend material storage life.
II. Cutting Process
Cutting Technology
Cut round steel into specified lengths based on design drawings. Common methods include shearing, laser cutting, or waterjet cutting to ensure edge flatness and dimensional accuracy (±0.5 mm).
Equipment Selection:
Small diameters (≤DN25): Manual saws or grinding wheel cutters.
Large diameters (≥DN200): Oxy-acetylene flame cutting.
III. Forming Process
Heating Treatment
Heat cut billets to a temperature adjusted for material type, reducing deformation resistance to facilitate subsequent extrusion or rolling.
Forming Techniques
Rolling/Extrusion: Use rolling mills or extruders to shape round steel into special-section pipe blanks. Control roller pressure and mold precision.
Drawing: Apply drawing for high-precision small-diameter pipes to achieve target dimensions^7.
Bending/Straightening: Use hydraulic presses or mechanical straightening equipment to correct pipe straightness and ensure cross-sectional tolerances.
IV. Finishing Operations
Beveling
Process pipe ends with beveling machines or angle grinders (e.g., 65° V-groove). Maintain a 1–1.5 mm blunt edge and 2–3 mm joint gap to ensure weld quality.
Surface Polishing
Enhance surface smoothness via mechanical polishing or chemical treatments, minimizing defects in subsequent welding or coating processes.
V. Welding and Assembly
Welding Process
Tack Welding:
For pipes ≤150 mm in diameter: 4 tack welds (5 mm each).
For pipes >150 mm: 6 tack welds to ensure root penetration.
Alignment Accuracy:
Weld axis straightness deviation ≤1 mm (≤100 mm diameter) or ≤2 mm (>100 mm diameter).
Connection Methods
Select welding (arc welding, gas-shielded welding) or mechanical connections (screws, flanges) based on application requirements to ensure structural stability.
VI. Post-Treatment and Inspection
Surface Coating
Apply hot-dip galvanizing by immersing pipes in molten zinc to form a corrosion-resistant layer, improving weather resistance and aesthetics^6.
Quality Inspection
Dimensional Checks: Use calipers or laser rangefinders to verify cross-sectional dimensions and straightness.
Non-Destructive Testing (NDT): Inspect weld integrity via X-ray or ultrasonic testing.
VII. Packaging and Storage
Wrap pipes in moisture-proof paper or secure them in wooden crates to prevent deformation during transport. Label specifications and production batches.
Product Main Characteristics
Multiple Cut Surface Shapes
Demand for different types of steel pipes, installation and machining, rectangular, square and other non-circular shapes, non-circular shaped cutting surfaces, different alignment process landscape support or construction demands
High Mechanical Strength And Bending Performance
In general, the refrigeration equipment has increased material density, its structural properties are good in ordinary world pipes, and its resistance to stiffness is outstanding in terms of its ability to accept pressure, so it can be used in high-quality cargo fields.1
Excellent Processing Suitability
Allows for cutting, cutting, bending, etc. Live processing, cooling technology step by step, completion of measurement accuracy, surface optical quality, full-fledged pumping process design requirements
Low production quality
The quality of raw materials for steel is low, the production technology is mature, and different types can be designed to reduce material consumption.
