DIN 3017 is a German Industrial Standard that specifies the requirements for high-quality worm drive hose clamps. It is one of the most recognized and respected standards for hose clamps globally, particularly in engineering and industries where reliability is critical. W2 stainless steel Germany type worm drive hose clamp is one type of din 3017 hose clamps.
Key Features of DIN 3017 Clamps
Materials:
Band: Must be made from stainless steel. The most common grades are:
A2 (304 stainless steel): For general corrosion resistance (e.g., automotive, industrial).
A4 (316 stainless steel): For enhanced corrosion resistance, especially in marine and chemical environments (resistant to saltwater and acids).
Screw and Housing: Also typically manufactured from stainless steel (A2 or A4) to ensure overall corrosion resistance and prevent galvanic corrosion between different metals.
Performance and Testing:
The standard sets rigorous benchmarks that clamps must meet:
Tensile Strength: The clamp must withstand a specified minimum pulling force without the band breaking or pulling out of the housing.
Pressure Resistance: It must seal a connection without leakage or failure at a defined proof pressure.
Vibration Resistance: The positive-lock mechanism is inherently designed to resist loosening under severe vibration.
Torque Strength: The screw must withstand a minimum torque without stripping.
Common Applications
DIN 3017 clamps are the preferred choice in applications where failure is not an option:
Automotive: Turbocharger and supercharger intercooler pipes, charge air systems, high-performance coolant and oil lines.
Marine: Engine room plumbing, fuel lines, cooling systems exposed to saltwater.
Aerospace: Ground support equipment and non-critical aircraft systems.
Industrial Machinery: Hydraulic systems, compressed air lines, chemical processing equipment.
Food and Beverage: When made from A4 (316) stainless steel, they are suitable for sanitary and wash-down environments.
