Industrial Exhaust Clamps Double Bolt Robust European Heavy Duty Double Band Hose Clamps
Features and Advantages
- Super Strong Tightening Force: The double-bolt structure increases tightening force by 50%-100%, capable of withstanding pressures above 0.8MPa to prevent pipeline detachment or leakage.
- Excellent Anti-Vibration Performance: Symmetrical force design reduces the risk of unilateral loosening, suitable for strong vibration environments such as construction machinery and ships.
- Large Diameter Adaptability: Typically suitable for pipe diameters ranging from 50-300mm, commonly used in industrial oil pipelines, large ventilation ducts, etc.
- Repeated Adjustability: Bolts can be disassembled and adjusted multiple times, facilitating pipeline maintenance and repair.
Application Scenarios
- Industrial Fields: Petrochemical pipelines, high-pressure pipelines of sewage treatment equipment, and mud conveying pipelines of mining machinery.
- Construction Machinery: Hydraulic systems of excavators/loaders, brake pipelines of cranes, and conveying pipes of concrete mixer trucks.
- Marine and Offshore Engineering: High-pressure oil pipelines in ship cabins, seawater cooling systems, and large pipeline connections on offshore platforms.
- Municipal Engineering: Water transmission pipelines of waterworks, high-pressure gas pipelines, and sealing and fixing of thermal heating pipelines.
Installation Precautions
1. Symmetrical Tightening: Use a torque wrench to tighten bolts in a diagonal sequence in 2-3 stages to ensure uniform force on both sides. Recommended torque values: 12-15N·m for M6 bolts, 20-25N·m for M8 bolts.
2. Washer Use: In high-pressure scenarios, use rubber or metal washers to enhance sealing and prevent the steel strap from scratching the pipeline.
3. Environmental Adaptation: Stainless steel materials must be selected for corrosive environments; high-temperature spring washers are required for high-temperature scenarios (e.g., exhaust pipes).
4. Regular Inspection: Check bolt tightness every quarter or every 500 operating hours to avoid loosening due to vibration.
Summary: With their double-bolt structure and thickened materials, double-head heavy-duty hose clamps are the first choice for high-pressure and large-diameter scenarios, especially in industrial applications with strict requirements for sealing and anti-vibration. However, attention must be paid to installation torque and environmental adaptation to achieve optimal performance.
