Stringent Safety Standards: Global regulatory bodies continue to impose stricter safety and environmental standards, necessitating robust testing and certification for all steering components.

These trends underscore the critical need for suppliers to not only meet current specifications but also to innovate and provide solutions that anticipate future industry demands for performance, reliability, and cost-effectiveness.

Technical Specifications & Materials

The performance of a Kragstuurbuis van hoë gehalte is fundamentally determined by its material composition and adherence to precise technical specifications. Our tubes are engineered to withstand the demanding conditions of hydraulic systems.

Typical Materials:

Carbon Steel Alloys: High-strength low-alloy (HSLA) steels like SAE 1010, SAE 1020, or equivalent are commonly used for their excellent tensile strength and fatigue resistance. These are often treated with anti-corrosion coatings.
Stainless Steel: For applications requiring superior corrosion resistance, such as those exposed to harsh chemicals or marine environments, grades like 304 or 316 stainless steel are preferred.
Aluminum Alloys: Used in applications where weight reduction is critical, often for return lines or lower-pressure sections, offering good thermal conductivity and corrosion resistance when properly treated.
Specialized Elastomers/Fluoropolymers: For flexible sections or hoses within the assembly, materials like EPDM, NBR, or FKM are chosen for their resilience to hydraulic fluids, temperature extremes, and chemical degradation.

Critical Technical Parameters:

Operating Pressure: Typically ranging from 70 Bar (1000 PSI) to 150 Bar (2200 PSI) for standard systems, with burst pressures often exceeding 400 Bar (5800 PSI) to ensure a safety factor of at least 4:1.
Temperatuurspeling: Designed to perform reliably from -40°C to +120°C, accommodating diverse operational climates and engine bay heat.
Corrosion Resistance: Achieved through galvanization, zinc-nickel plating, or specialized organic coatings, providing over 400 hours of salt spray resistance (ASTM B117).
Vibration Fatigue Life: Tubes must withstand millions of vibration cycles at operational frequencies without developing cracks or leaks, validated through rigorous dyno testing to SAE J188 standards.
Internal Surface Finish: Smooth internal bore is crucial to minimize flow restriction and cavitation, ensuring optimal fluid dynamics and pump longevity.
Bending Radius: Precision-controlled bending to meet OEM specifications without compromising tube integrity or wall thickness.

High-Quality Power Steering Tubes: Durable & Leak-Proof Performance

These parameters are meticulously controlled throughout the manufacturing process, ensuring that each Kragstuurbuis van hoë gehalte meets or exceeds industry benchmarks for performance and reliability.

Manufacturing Process Flow for High-Quality Power Steering Tubes

The production of a Kragstuurbuis van hoë gehalte involves a multi-stage, precision-engineered process designed to ensure structural integrity, dimensional accuracy, and optimal performance under extreme conditions. Our manufacturing adheres to stringent international standards like ISO 9001 and IATF 16949.

Process Steps:

Material Selection and Preparation:
High-grade seamless steel tubing (e.g., SAE 1010/1020, DIN 2391/2445) or stainless steel is sourced from certified suppliers. Incoming material undergoes spectrometric analysis and mechanical testing (tensile strength, yield strength, elongation) to verify compliance with specifications.
Tube Cutting and Deburring:
Tubes are cut to precise lengths using CNC-controlled saws or laser cutting, minimizing material waste and ensuring dimensional accuracy. Ends are meticulously deburred to prevent internal contamination and facilitate subsequent processing.
Precision Bending (CNC Machining):
Advanced CNC tube bending machines form the tubes into complex geometries with tight tolerances. This process requires precise tooling and programming to avoid kinking, flattening, or excessive wall thinning at bends. Optical scanning ensures conformity to 3D CAD models.
End Forming and Flaring:
Tube ends are precisely formed (e.g., flaring, swaging, beading) to create secure, leak-proof connections with hydraulic fittings. This often involves cold forming processes that enhance material strength at critical connection points.
Brazing or Welding (for multi-component assemblies):
Where multiple tube segments or fittings need joining, automated brazing or TIG/MIG welding processes are employed. Weld integrity is verified via visual inspection, dye penetrant testing, or X-ray inspection to ensure no porosity or structural flaws.
Cleaning and Surface Treatment:
Tubes undergo multi-stage cleaning (e.g., alkaline wash, ultrasonic cleaning, passivation for stainless steel) to remove oils, debris, and contaminants. This is followed by corrosion-resistant coatings, such as zinc-nickel plating (offering >400 hours salt spray resistance per ASTM B117) or epoxy e-coating, applied uniformly for optimal protection.
Assembly (if applicable):
For complex assemblies, additional components like brackets, isolators, or flexible hose sections are integrated with specialized tooling.
Rigorous Testing and Quality Control:
Every tube undergoes comprehensive testing:
- Leak Testing: 100% pneumatic pressure testing or hydrostatic pressure testing to specified burst pressures (e.g., 4x working pressure).
- Dimensional Inspection: CMM (Coordinate Measuring Machine) or optical scanning ensures all dimensions, bend angles, and end forms meet tight tolerances.
- Functional Testing: Vibration fatigue testing (SAE J188, J2053), thermal cycling, and pressure pulsation tests simulate real-world conditions to validate service life and reliability.
- Cleanliness Verification: Internal cleanliness tests to prevent contamination of hydraulic systems.
Packaging and Delivery:
Finished tubes are carefully packaged to prevent damage and contamination during transit, often using protective caps for open ends.

This meticulous process ensures a service life often exceeding 10 years or 150,000 miles in typical automotive applications, significantly reducing maintenance needs and improving overall system reliability. Target industries include automotive OEM, heavy equipment manufacturing, and specialized industrial hydraulic systems where reliable fluid transfer is paramount.

This extends component life, especially in regions with harsh weather or in industrial settings. Our coatings often surpass 1000 hours of salt spray resistance for specific applications, greatly exceeding standard requirements.
Optimized Vibration Damping: Precision bending and optional integrated damping elements (such as resonance dampeners) are designed to absorb system vibrations and fluid pulsations. This reduces NVH (Noise, Vibration, and Harshness), enhancing driver comfort and preventing premature wear on pumps and racks.
Enhanced Material Durability: Utilization of high-strength steel alloys or robust stainless steel, combined with meticulous heat treatments, provides excellent fatigue resistance and structural integrity over millions of operational cycles. This translates into a significantly longer service life compared to standard alternatives.
Precision Dimensional Accuracy: Manufactured with tight tolerances using CNC technology, ensuring perfect fitment and seamless integration with existing hydraulic systems. This eliminates installation issues and potential leak points.
Leak-Proof Connections: Advanced end-forming techniques (e.g., precise flaring, double-flaring, or O-ring boss connections) create robust, leak-free seals when properly installed with compatible fittings, critical for maintaining hydraulic system integrity and fluid levels.
High Internal Cleanliness: Tubes are thoroughly cleaned to remove manufacturing residues, preventing contamination of the hydraulic fluid. This protects sensitive components like steering pumps and valves from abrasive wear, extending the life of the entire power steering system.

These advantages collectively contribute to a more reliable, durable, and safer power steering system, directly impacting vehicle uptime and operational costs.
