When it comes to building or maintaining sanitary systems in industries like food, beverage, and pharmaceuticals, reliability isn’t optional. Every connection must be strong, leak-proof, and compliant with strict hygiene standards. Bolted clamps are one of the most trusted tools to achieve that.
At DuvaSanitary, we supply high-quality bolted clamps that deliver the strength, durability, and precision required for critical process systems. But what makes bolted clamps different from other clamp types—and when should you use them?
What Is a Bolted Clamp?
A bolted clamp is a mechanical connector used to join two ferrules or flanges by tightening a bolt (or set of bolts) to create a secure, sealed connection. Unlike quick-release clamps or hinged designs, bolted clamps offer a more permanent and robust hold, ideal for high-pressure or high-temperature applications.
In a sanitary system, bolted clamps are commonly used where:
- Connections are not frequently disassembled
- Strong, vibration-resistant joints are needed
- Higher operating stress or pressure is expected
Why Choose Bolted Clamps?
While there are many types of clamps available, bolted clamps offer unique benefits that make them ideal for certain scenarios:
1. Stronger Hold Under Pressure
Bolted clamps distribute force evenly and securely, making them perfect for systems with high internal pressure or mechanical stress.
2. Vibration Resistance
In environments where pumps, mixers, or moving parts create vibration, bolted clamps maintain their grip, reducing the risk of leaks or loosening over time.
3. Durability
With fewer moving parts and a solid construction, bolted clamps tend to outlast lighter clamp styles—especially in demanding industrial settings.
4. Precise Compression
By adjusting the torque during installation, you can fine-tune the compression on the gasket for an exact, leak-free seal.
When to Use Bolted Clamps in Sanitary Systems
Bolted clamps are often the go-to choice for:
- Permanent or semi-permanent installations
- Systems subject to thermal cycling or mechanical movement
- Applications requiring maximum seal integrity
- Installations where space or access is limited for frequent disassembly
They’re widely used in processing facilities for dairy, beer, pharmaceuticals, and cosmetics, where sanitary compliance and mechanical strength must go hand in hand.
Choosing the Right Bolted Clamp
When selecting a bolted clamp, consider the following:
- Size and compatibility: Match the clamp to your ferrule or flange size.
- Material: Most sanitary bolted clamps are made from 304 or 316L stainless steel for corrosion resistance.
- Bolt type and torque requirements: Make sure the hardware is compatible with your tools and procedures.
- Certifications: Look for 3-A, FDA, or ASME compliance if required by your industry.
At DuvaSanitary, we offer a curated selection of bolted clamps that meet strict sanitary standards. Our clamps are engineered for performance and built to last, even in the most demanding environments.
Final Thoughts
Bolted clamps may not be as quick to install as their hinged counterparts, but their strength, stability, and reliability make them indispensable in many sanitary systems. When the process can’t afford failure, a bolted connection can provide peace of mind.
