Advantages of Special-Shaped Tubes

Structural and mechanical properties

Excellent structural and mechanical properties, with higher bending and torsional stiffness.

Outstanding resistance to local instability

The flat surface enables more uniform pressure distribution, making it less prone to local buckling, especially when subjected to pressure or impact.

Connection and installation

Easy connection and installation, which simplifies the connection with other components.

Material and space saving

Achieving lightweight design with high space utilization. Special-shaped tubes can perfectly fit the structural space of equipment or products.

Core Working Principles

Moment of Inertia Principle (Bending and Torsional Resistance)

The bending and torsional resistance of a component mainly depends on how the material is distributed in its cross-sectional shape. The farther the material is distributed from the central axis, the larger the moment of inertia, and the stronger the bending resistance.

Surface Area-to-Volume Ratio Principle (Heat Exchange and Connection)

In heat exchange applications, a larger surface area means higher heat exchange efficiency. In connections, a larger flat contact area means a more stable connection.

Space Filling and Shape Fitting Principle

Maximize the use of available space, or match a specific shape to achieve functionality or aesthetics.

Stress Distribution Principle

Through reasonable shape design, stress can be guided and evenly distributed, avoiding failure caused by stress concentration.

Application scenarios

Automotive Manufacturing

Exhaust manifolds, tailpipes, fuel pipes, water pipes, body components, seats, etc.

Furniture and Home Decoration

High-end office furniture (table legs, partition frames); modern-style bed frames, sofa skeletons; store display racks and cabinets; external structures of household appliances.

Energy and Heat Exchange Industry

Air conditioning condensers and evaporators; automotive radiators and intercoolers; heat exchange pipes in power stations.

Manufacturing Process

Material

For each batch of materials, material verification and material performance testing are conducted to ensure the correct materials that meet requirements are used.

Tube Manufacturing

Continuous tube manufacturing equipment is used, capable of welding processing for materials with a thickness of 0.15–2.5mm and a tube diameter of 25–76mm.

Forming

Independently developed internal high-pressure forming equipment is adopted, which realizes internal high-pressure forming with water. It can smoothly achieve physical deformation of products without damaging the material, and features special-shaped deformation processing, environmental friendliness, and high efficiency.

Leakage Testing

100% immersion leak testing is performed.

Final Inspection/Packaging

All key installation dimensions undergo 100% full inspection to ensure no defective products are released.

Test items & standards

Cross-Sectional Dimension Inspection

Purpose: To inspect bellows-related data, including the thickness error rate after forming and the weld penetration depth.
Testing Equipment: Coordinate Measuring Machine (CMM) / Profile Projector / Metallurgical Microscope

Corrosion Resistance Test

Purpose: To verify the surface corrosion resistance of bellows when exposed to salt spray conditions for a long time.
Testing Equipment: Salt Spray Test Chamber

Material Physical Property Inspection

Purpose: To test the elongation and tensile strength of the material.
Testing Equipment: Universal Tensile Testing Machine

Weld Strength Inspection

Purpose: Through tensile tests / destructive tensile tests, verify whether the weld strength is sufficient, whether the weld penetration meets requirements, and whether there are air holes in the weld structure.
Testing Equipment: Tensile Testing Machine / Profile Projector

Full-Size Product Inspection

Purpose: Inspect all dimensions of the product in accordance with the product drawing to ensure all data meet customer requirements.

Air Tightness Inspection

Purpose: The air tightness test aims to verify whether there is leakage in the bellows and its connection parts, ensuring sealing performance and reliability under pressure conditions.
Testing Equipment: (Test method: Fill the bellows with gas of a certain pressure, such as air or nitrogen, and judge the sealing performance by detecting pressure drop or air bubble leakage.)
