10. FAQ (Heavy Duty Hose Clamp Industry Glossary)
FAQ: Professional Terminology Explained
Q1: What is the difference between SS201 and SS304 in heavy duty hose clamps?
A1: SS304 contains more nickel and chromium, offering superior corrosion and temperature resistance, resulting in longer service life and better performance in harsh environments than SS201.
Q2: What is “band width,” and how does it affect performance?
A2: Band width refers to the width of the clamp’s steel strip. Wider bands (e.g., 16mm or 20mm) distribute clamping force over a larger area, reducing hose deformation and leak risk in high-pressure applications.
Q3: What standards should stainless steel hose clamps meet?
A3: Look for ISO 9001, ISO 2852, ANSI B1.1, and for specialized applications (food/water), additional FDA or EN 682 certification.
Q4: What is “service life” and how is it measured?
A4: Service life measures how long a clamp maintains its function under defined conditions. For SS304 clamps, it exceeds 15 years with proper environmental matching and installation.
Q5: What torque should I apply to a heavy duty hose clamp?
A5: Typical recommended torque: 7–9 Nm for SS304/SS201 clamps. Always refer to the manufacturer’s spec sheet and use a calibrated torque wrench.
Q6: What is the advantage of CNC manufacturing in clamp production?
A6: CNC processes provide unparalleled repeatability, allow for tighter tolerances, and ensure each clamp meets specification, especially critical for OEM and high-safety applications.
Q7: What post-sale support do you offer?
A7: Puxing Clamp provides 2-year product warranties, technical installation guides, acceptance test reports, and responsive engineering support for all heavy duty hose clamp shipments.
