Tube inserts serve several functions while contributing to the structures of which they are a part. They are far from being just aesthetic elements: in many cases they can serve to insulate the inside of the tube, making it watertight. They also help to give structures a more solid foundation and, in the process, make sure that it is stronger for a longer period of time. We would now like to show you the different types of tube inserts that exist and their functions and characteristics.
How are tube inserts made and used
Firstly, we should note that tube inserts can have different uses which will in fact be indicated by their shape. In fact, it is the function that gives them their shape, so we can find different types according to the purpose that these inserts have.
These inserts can help prevent corrosion of the tubes, keep them watertight, prevent compression, etc. They are generally made of polymers as the main material. This makes them cheap and very versatile parts that can be adapted to different sizes.
It must be said, by the way, that plastic is generally the best material for its great versatility, much more than the metal equivalents. Anyway, as a general characteristic we can say that they are easy to use and adapt to any piece and that they come in different sizes and shapes. To learn more about these indispensable elements in any structure, we recommend that you take a look at our news so you don’t miss anything and so we can advise you as a professional service.
Tube types according to their shape
We will first discuss types of tube inserts according to their shape.
Square-shaped inserts
Within the types of tube inserts with a square shape, we can find several subtypes. Depending on their characteristics, they can be used for different purposes and can offer different finishes in terms of sealing.
- Inner grooved ferrule
- Inner grooved ferrule for structural tubes
- Inner threaded ferrule
- Sloping inner grooved ferrule
- Sloping grooved inner ferrule
- Inner grooved end insert
- Chrome-plated inner grooved end insert
- Glossy inner grooved end insert
- Square outer ferrule
- Flexible square outer ferrule
Round inserts
This type of insert is suitable for round tubes and, again, depending on its own characteristics it can serve various functions depending on the purpose of the tube itself, as well as the specific needs of the structure it is used with.
- Inner grooved ferrule
- Reinforced inner grooved ferrule
- Lightweight, hemispherical anti-slip ferrule
- Flat inner ferrule
- Inner threaded ferrule
- Inner grooved end insert
- Chrome-type inner grooved end insert
- Semi-spherical inner grooved end insert
- Inner grooved end insert with gloss finish
Rectangular inserts
Again, these are inserts suitable for rectangular tubes and their shape indicates the function they will have within a given structure.
- Inner grooved ferrule
Inner grooved end insert- Rectangular outer ferrule
- Inner threaded ferrule
Inner grooved end insertOval inserts
Oval shaped for tubes that are usually used as part of decorative or designed elements of a structure.
- Inner grooved ferrule
- Inner grooved end insert
External tube inserts
This type of insert is used for the outer surface of a certain structure and generally has a double purpose: on the one hand it is decorative and, on the other, it protects against humidity and dirt. As you can see, their shape is adapted to that of the tube in which they are fitted.
- Exterior baton ferrule with metal washer
- Flexible outer rounded ferrule
- Reinforced outer ferrule
- Rectangular outer ferrule
- Rounded outer ferrule
Adjustable feet
These inserts regulate both the height and length of the tubes to which they are attached. In doing so, they add versatility and mobility to the structures they are part of. There are the following types:
- Inner threaded ferrule
- Adjustable feet
- Bases with ball-and-socket joints
- Adjustable feet with ball-and-socket joint
- Inner threaded ferrule
Special tube inserts
These are inserts generally with irregular shapes unlike those above and which can fulfil complementary functions to those of protection and sealing of the interior.
- Horizontal or clamp ferrule
- Rack tube ferrule
- Snap-in bumper
- Snap-in for round tube
- Oval ferrule with flat base
- Nut cap
- Semi-spherical bumper
- Ferrule for horizontal tubes
- Shoe
Types of tube inserts according to their design
We will now talk about the types of tube inserts that exist according to their design. We can identify several types based on this criterion.
Clamp elements
These are inserts that usually fasten to the tube with a bolt and their joints are made of rubber.
Threaded
In general, these are inserts for pipes that are in high demand and used in various sectors ranging from communications to insulation for gas and water. They are made of Special materials for sealing their joints. This is why we don’t need to use additional sealants to make them watertight.
Types of tube inserts according by placement
We can also identify two types depending on where the inserts are placed.
Plugs for external tubes
These are generally used more as decorative elements. However, they also serve another purpose, which is to protect the inside of the tube from possible obstructions, as well as from moisture.
Internal type
At this point we must talk about the finned inserts which have a grooved design that allows them to be held fast by the internal part of the tube. These inserts fit in the socket and the top of the plugs are sealed with a cap-like design.
Other types of tube inserts
Finally, we will discuss other types of tube inserts that have specific functions of various kinds.
For rear end cover
They serve to isolate part of a facility or to protect a particular system from waste or residue spillage.
Shipping Covers
They are used to protect a pipe from possible damage or deformation during the shipping process.
In short, at Fortaps you can find the widest catalogue of tube caps to find the type and model that best suits your own needs.
