Double Bolt Hose Clamp | Heavy Duty Zinc Plated Iron Clamps for High Pressure

The Iron Double Bolt Clamps, more accurately described as Forged Iron Double Bolt Hose Clamp, is a heavy-duty, industrial-grade clamping device. It is recognized for its exceptional strength and rigid construction, designed for the most demanding applications where a permanent, leak-proof seal is critical on hoses, pipes, or tubing.

Key Features of Iron double bolt clamps

Malleable or Forged Iron Body: The clamp's main saddle or frame is constructed from malleable iron or forged steel. This material is heat-treated, giving it tremendous strength and shock resistance, making it much stronger than clamps made from sheet metal.

Dual Bolt Mechanism: This is the defining feature. It uses two high-tensile steel bolts (often zinc-plated or coated) and nuts to apply closing force. Turning the bolts draws the two ends of the rigid saddle together, creating a powerful and even clamping pressure.

Rigid Saddle Design: Unlike the flexible band of a worm-gear or even a stainless steel double bolt clamp, the iron clamp has a solid, pre-formed saddle. This rigid structure ensures that the clamping force is applied evenly and prevents the hose from being deformed or ovalized under high pressure.

Heavy-Duty Construction: Every component is built for maximum durability and performance under extreme conditions, including high pressure, intense vibration, and temperature fluctuations.

Benefits of iron double bolt clamps

Maximum Strength and Pressure Rating: This is the primary advantage. The rigid iron construction provides the highest mechanical strength of common clamp types, making it suitable for extremely high-pressure systems.

Superior Vibration Resistance: The dual-bolt design, combined with the rigid saddle, makes it virtually impossible for the clamp to loosen under vibration, a critical feature for industrial machinery, pumps, and engines.

Prevents Hose Collapse: The rigid saddle fully supports the hose, preventing it from collapsing or distorting under vacuum conditions or extreme clamping force.

Durability and Longevity: The robust construction ensures a long service life in tough environments. While it can rust, coatings can mitigate this.

Double bolt clamps Q&A

Q: Why use double bolt clamps instead of single bolt T-bolt clamps?

A: Double bolt clamps provide dual-side compression and a more rigid saddle, making them superior for extremely thick-walled industrial hoses where a single bolt might not apply enough uniform pressure.

Q: Are these double bolt clamps suitable for high-vibration environments?

A: Yes, the dual-bolt mechanism and reinforced machine bolts are specifically designed to resist loosening caused by intense vibration in mining, construction, and pump systems.

Q: What is the surface treatment of these clamps?

A: Our clamps are standard zinc-plated (Cr3+ or Cr6+) for excellent corrosion resistance. Stainless steel options are also available for marine applications.
