When it comes to tri-clamp connections, there are two main types: the 2-segment (single hinge) and the 3-segment (double hinge). As a sommelier and brewer, I have worked with both types and can share my personal experiences with you.
Let's start with the 3-segment style clamps, which are the ones I primarily use and recommend. These clamps are often considered to be more “heavy duty” due to their sturdy construction. The main advantage of the 3-segment type is that they are easier to install in tight spaces. This can be particularly useful in breweries or wineries where equipment is often packed closely together. I have encountered situations where the 2-segment clamps simply wouldn't fit due to limited space, but the 3-segment ones saved the day.
The 3-segment clamps consist of three separate pieces that are hinged together. This design allows for more flexibility and ease of use. When opening the clamp, the two outer segments swing outwards, creating a wider opening. This makes it simpler to attach or detach fittings, especially when dealing with larger diameter pipes or hoses. I have found this feature to be extremely helpful when connecting and disconnecting various components during the brewing process.
On the other hand, the 2-segment clamps have only one hinge and consist of two pieces. While they can be suitable for certain applications, I generally find them to be less versatile compared to their 3-segment counterparts. These clamps have a narrower opening when fully open, which can make it more challenging to attach or detach fittings in tight spaces. However, they can still be useful in situations where space is not a constraint and a secure connection is required.
The 3-segment tri-clamp fittings are my preferred choice due to their heavy-duty construction and ease of installation in tight spaces. The ability to create a wider opening when attaching or detaching fittings makes them more versatile in various brewing and winemaking applications. However, the 2-segment clamps can still serve their purpose in situations where space is not a limitation. Ultimately, the choice between the two types of tri-clamp connections depends on the specific needs and constraints of the brewing or winemaking setup.
