Key Features of double bolt hose clamps stainless steel:
Dual Bolt & Saddle Mechanism: This is the defining feature. Instead of a single screw, it uses two bolts that tighten a solid, band-shaped saddle. This design applies pressure evenly around the entire circumference of the hose, eliminating weak points and preventing the "hot spots" common with worm-drive clamps.
Heavy-Duty Construction: Made from high-grade stainless steel (typically 304 or 316), these clamps offer exceptional strength and durability. They are built to withstand high pressure, intense vibration, and mechanical stress without failing.
Superior Corrosion Resistance: The use of stainless steel makes them ideal for harsh environments. They resist rust and corrosion from water, chemicals, salt spray, and extreme temperatures, ensuring a long service life.
Wide & Reinforced Band: The band is significantly wider and thicker than that of a standard clamp. This distributes clamping force over a larger area of the hose, preventing it from cutting into or damaging softer hose materials.
High Tensile Strength: The materials and design give these clamps a very high tensile strength, meaning they can exert and maintain a tremendous amount of clamping force without stretching or breaking.
How to Choose the Right One:
Size: Ensure the clamp's diameter range matches your hose's outer diameter.
Stainless Steel Grade:
304 (A2): Excellent for most general and industrial applications with good corrosion resistance.
316 (A4): Superior corrosion resistance, essential for marine environments or exposure to harsh chemicals.
Band Width & Thickness: For higher pressures and larger diameters, a wider and thicker band is necessary.
Q&A for Stainless Steel Double Bolt Hose Clamp
Q: Is this double bolt clamp made entirely of stainless steel?
A: Yes, in our W4 and W5 grades, every component—including the band, the bridge, and the bolts—is made from high-quality stainless steel to prevent galvanic corrosion.
Q: Can these clamps be used in offshore oil and gas applications?
A: Absolutely. Our AISI 316 (W5) stainless steel double bolt clamps are specifically designed to withstand harsh saltwater and chemical exposures found in offshore environments.
Q: What is the benefit of the "double bolt" design for stainless steel hoses?
A: The dual-bolt mechanism provides much higher torque and even pressure distribution than standard T-bolt clamps, ensuring a leak-proof seal on thick-walled or high-pressure stainless steel reinforced hoses.
