Hose Swing Bending Testing Machine: Precision Evaluation for Gas Appliance Hose Durability
The Hose Swing Bending Testing Machine is a specialized instrument engineered to conduct swing bending tests on stainless steel corrugated hoses used in gas appliance connections. These hoses are critical for safe gas transmission, and their ability to withstand repeated swinging and bending—common in installation, maintenance, or daily use—is vital for preventing leaks and ensuring long-term reliability. The machine subjects hoses to controlled oscillating movements, simulating real-world stress conditions, and is operated via a liquid crystal touchscreen. It automatically stops once the preset number of test cycles is reached, guaranteeing consistent and accurate results.
This tester strictly complies with GB/T 41317-2022, the Chinese national standard governing the performance testing of stainless steel corrugated hoses for gas appliances. Adherence to this standard ensures that test results align with industry safety and quality benchmarks, making the machine indispensable for manufacturers, quality control teams, and regulatory bodies focused on gas system safety.
Premium Engineering
Crafted with exquisite machining precision and a unique industrial design, the machine balances functionality with user-centricity. Its robust frame and high-grade materials ensure stability during high-cycle swing tests, even under continuous operation. Ergonomic features—such as easy hose mounting points, clear status indicators, and accessible maintenance panels—simplify operation, reducing downtime and enhancing workflow efficiency. This attention to engineering detail ensures durability in demanding industrial environments.
Intelligent Control System
Equipped with a PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) large-color LCD touchscreen, the machine offers intuitive and precise control. Operators can effortlessly set key parameters—swing angle, speed, cycle count, and pressure—via the user-friendly interface, which also displays real-time data such as cycle progress, current angle, and pressure readings. This automation minimizes human error, streamlines testing processes, and ensures consistency across multiple tests.
Precision Motion Control
- High-Performance Servo System: A powerful servo motor and driver deliver accurate regulation of swing angles within the -30°～30° range (digitally adjustable), strictly adhering to the requirements of GB/T 41317-2022. This precision ensures that each oscillation replicates real-world bending stress, critical for reliable durability assessments.
- Closed-Loop Speed Stability: A self-adjusting closed-loop control system maintains a steady swing speed of 30 cycles/min (with digital adjustability), even as hose flexibility changes during testing. This stability prevents speed fluctuations that could distort results, ensuring uniform force application throughout the test.
Reliability & Safety Features
- Power Failure Memory Function: In the event of a power outage, the machine automatically saves the last completed cycle, allowing seamless resumption of testing without restarting. This feature minimizes downtime and preserves data integrity, especially for long-duration tests.
- Automatic Cycle Termination: Once the preset cycle count (0~9,999,999) is reached, the machine stops immediately, preventing over-testing and protecting both the specimen and equipment.
- Gas Safety Integration: For tests requiring gas pressure simulation, the system includes ventilation/exhaust controls and automatic gas source shutdown when specified pressure thresholds (monitored via a 0～100kPa gauge) are met. This prevents hazardous gas buildup, enhancing workplace safety.
- Operator Protection: A reinforced safety protection door encloses the testing area, shielding operators from moving parts and potential hose failure during high-stress cycles, ensuring compliance with industrial safety protocols.

These parameters reflect the machine’s focus on precision and safety. The 5kg load simulates real-world stress from attached gas appliances, while the wide cycle range accommodates both short-term quality checks and long-term durability assessments. Its substantial weight (350kg) and sturdy dimensions ensure stability during high-speed oscillations, preventing vibration-related inaccuracies.
The Hose Swing Bending Testing Machine is specifically designed for evaluating stainless steel corrugated hoses used in:
- Residential Gas Appliances: Stoves, water heaters, and boilers, where hoses often endure minor swings during use.
- Commercial Kitchens: Heavy-duty gas equipment, where hoses may be subjected to frequent movement during cleaning or repositioning.
- Industrial Gas Systems: Manufacturing facilities, where hose durability under repeated bending is critical for operational safety.
By simulating these real-world conditions, the machine helps manufacturers identify weak points, optimize hose design, and ensure compliance with GB/T 41317-2022. For regulatory bodies and third-party labs, it provides a standardized method to verify product safety, reducing the risk of gas-related accidents.
The Hose Swing Bending Testing Machine combines advanced motion control, intelligent automation, and robust safety features to deliver accurate, reliable data on the bending durability of gas appliance hoses. Its adherence to GB/T 41317-2022, precision engineering, and user-centric design make it an essential tool for ensuring the safety and performance of stainless steel corrugated hoses. Whether used in production quality control or research and development, this machine empowers stakeholders to uphold the highest standards of reliability in critical gas systems.
