Tri Clamp fittings

Tri Clamp fittings are hygienic stainless couplings. It guarantees unimpeded media flow and particularly high sterility, which is why it is used in many demanding industrial sectors such as pharmaceuticals, cosmetics, chemicals, biotechnology, and food. The fittings are made to different standards, but in most cases, their basic dimensions remain the same. 

In terms of design, these products stand out among the competition because they are symmetrical flange couplings. Tri Clamp fittings consist of four parts: two flanges, a seal, and a clamp that holds everything together. In addition, they also feature a higher quality surface finish, making it much less porous.

How are Tri Clamp fittings constructed?

Tri Clamp fittings consist of four components:

  • two flanges, 
  • a seal,
  • a screwed clamp.

Apart from the seal, all parts are made of stainless steel. This makes the couplings highly resistant to a wide range of media. In addition, they are mechanically very robust.

As far as the seal is concerned, several materials are used to produce it. EPDM rubber is very popular, but you will also find products made of NBR, PTFE or viton on the market.

What are the different types of Tri Clamp fittings?

Below, we listed different types of tri clamp fittings in terms of the assembly method. There are two basic product versions available:

  • with hose stub (connected by means of a clamp or collet);
  • weld-on.

What are the dimensions and other specifications Tri Clamp fittings?

Tri Clamp fittings are available in a number of versions. However, as they are manufactured according to different standards (e.g. ISO 2852, DIN 32676, BS 4825-3, ASME-BPE), the dimension tables may differ significantly.

Therefore, take into account that a product made to one standard may not be compatible with one made to another standard.

When it comes to maximum working pressure, it depends primarily on the size of the coupling. As a general rule of thumb, we assume the following division:

  • for fittings under 2 inches — at least 16 bar; 
  • for fittings over 2 inches — 10 bar.

However, remember that you should also take into account the maximum working pressure of the rest of the installation, i.e. hoses and pipes, among other things.

How to connect the Tri Clamp fitting together?

Before you assemble the Tri Clamp fitting into one piece, make sure that the two parts with flanges fit together. To do this, pay attention to two things:

  • the diameter of the flange (both must be identical, otherwise you will not connect them); 
  • the nominal diameter (this is the diameter of the passage, which should also be identical — otherwise there will be a rim inside, which will reduce the hygiene of the installation drastically).

Once you have selected the parts of the fitting properly, move on to assembly. It is very simple. Just follow the steps below:

  1. Place the seal between the flanges; 
  2. Press one flange against the other. 
  3. Place a clamp on both flanges and tighten firmly.

However, take into account that, depending on the type of connector (weld-on or with hose stub), the difficulty of assembly will vary. Be particularly careful when welding, as the final weld should maintain a high level of hygiene.

What does this mean? That there must be no crevices or other places on its surface where the medium could accumulate.

FAQ

How to choose the right Tri Clamp fitting?

arrow-up

When selecting the Tri Clamp fitting, pay particular attention to the flange diameter and the passage diameter. They should be identical on both parts. And if you are using a coupling with a stub, you should also measure the diameter of the stub. This will help you identify which standard you are dealing with, which will make it easier to choose the right components.

What does the improper selection of Tri Clamp fittings lead to?

arrow-up

When you poorly select the parts of a Tri Clamp fitting, there is a risk of so-called "dead zones" forming due to differences in internal diameters. Medium will accumulate in the faults, which will lead to the growth of bacteria and microorganisms over time.

Why use Tri Clamp fittings?

arrow-up

Tri Clamp fittings are well worth using because they offer a very high level of hygienic flow and a low risk of contamination of the medium. For this reason, they are widely used in industries where sanitary conditions play an important role.
