Dual Bead Worm Gear Clamp stainless steel Perforated Band America Stainless Steel Hose Clamp American lined Pipe Clamp

The American-style lined hose clamp is a type of hose clamp with a built-in protective lining structure, and its core features are as follows:

- Structural Design:
It adds a lining pad inside the steel strap based on the traditional American-style hose clamp (steel strap + cover), which wraps around the inner side of the steel strap to prevent the strap from directly contacting the pipe surface.
- Main Functions:
- Anti-Wear: The lining pad isolates the steel strap from the pipe, preventing the hose (such as rubber or plastic pipes) from being scratched or abraded during tightening.
- Vibration and Noise Reduction: The lining material buffers vibrations and reduces noise caused by friction between the pipe and the clamp.
- Enhanced Sealing: The lining fills gaps to improve the tightness of the connection, making it particularly suitable for sensitive or precision pipelines.

Size List

Here's how to select an American-style cover hose clamp:

Pipe Diameter

- Accurately measure the outer diameter of the pipe to be fixed. The inner diameter of the hose clamp should be slightly smaller than the pipe's outer diameter, typically 0.5–1 mm smaller, to ensure a tight fit. For example, if the pipe’s outer diameter is 30 mm, choose a clamp with an inner diameter of 29–29.5 mm.

Tightening Force Requirements

- For high-pressure, high-vibration environments (such as automotive engines), select large-sized, high-strength clamps with a steel strap width of 12.7 mm or more to provide sufficient tightening force.

- For low-pressure ordinary water or gas pipes, medium or small-sized clamps with a strap width of 8–10 mm are suitable.

Working Environment

- In humid or corrosive environments (e.g., chemical workshops, outdoor wet areas), choose stainless steel clamps (e.g., 304, 316) for enhanced corrosion resistance.

- In dry, non-corrosive ordinary environments, galvanized carbon steel clamps offer better cost-performance.
