Wholesales Butt Joint Exhaust Clamp

The Butt Joint Exhaust Clamp, also commonly known as a Band Clamp or Slip Joint Clamp, is a high-performance, adjustable clamping device designed for sealing and securing overlapping sections of exhaust pipes, particularly at slip-fit or lap joints. It is the preferred choice in automotive, marine, and industrial exhaust systems due to its ability to create a strong, uniform seal around the entire circumference of the pipe, effectively preventing exhaust leaks, reducing noise, and providing a secure mechanical connection.

Components of butt joint exhaust clamp

1. Fasteners:

Bolts & Nuts: Two sets of Hex Head Bolts and matching Nuts.

Grade/Coating: Grade 8.8 (a medium-tensile strength carbon steel), electroplated with Zinc for basic corrosion protection and durability.

Function: These are the primary tightening mechanisms. The bolts pass through the folded ends of the band and the "I-beam" spacer. The Grade 8.8 provides sufficient strength for high-torque tightening without shearing, ensuring the clamp can withstand the vibration and thermal cycling of an exhaust system.

2. Pressure Distribution Spacer (The "I-Beam"):

Material: Aluminum Alloy (lightweight and strong).

Design: "I"-beam or "H"-beam profile.

Function: This is a critical component. It sits between the two bolt heads/nuts and the clamp band. Its design serves two key purposes:

Prevents Band Collapse: It stops the folded ends of the thin stainless steel band from buckling or deforming when the bolts are tightened.

Ensures Even Pressure: It transfers the tightening force from the bolts evenly across the full width of the band, allowing for a consistent and uniform seal around the entire pipe circumference.

3. Clamp Band:

Material: Stainless Steel (typically Grade 201 or 304 for corrosion resistance).

Dimensions: 75mm wide and 0.6mm thick.

Function: This is the main body of the clamp that wraps around the exhaust pipes. The 75mm width provides a broad sealing surface for superior leak prevention, while the 0.6mm thickness offers an excellent balance of strength and flexibility for easy tightening and a secure hold.

Application of butt joint exhuast clamp

Custom Fabrication: In custom-built exhaust systems for hot rods, race cars, motorcycles, or specialty equipment, fabricators frequently use reducing pipes to transition between different components. The reducing lap clamp provides a reliable, removable connection at these joints.

Connecting to Downpipes or Headers: In turbocharged applications or performance upgrades, aftermarket downpipes or headers often have a larger diameter than the mid-section of the exhaust. A reducing clamp is perfect for this high-performance junction.

Industrial & Marine Exhaust Systems: Used in diesel generators, marine engines, and industrial machinery where exhaust piping may need to transition between sizes due to space constraints or design requirements, and a leak-free seal is critical for safety and efficiency.
