SEG: New pipe conveyor commissioning in South East Asia
Sig: one of the main Pipe Conveyor Manufacturers
SIG is one of the most reliable and skilled manufacturers of pipe rubber conveyor belts.
Last year, in 2023, SIG successfully started an iconic steel cord pipe conveyor supply. It dealt with a 9km length item, with a tube diameter of 500mm, delivered to an important quarry in the Middle East.
Today, however, we tell you the crucial data related to one more of our important pipe conveyor installations.
As a matter of fact, in this case, one of the biggest worldwide OEMs (Original Equipment Manufacturers) has commissioned SIG to the realisation of two textile pipe conveyors, 350mm tube diameter, for 860 meters globally, to be delivered to one of the major cement players in SE Asia.
The two belts are now in operation with satisfaction from both parties: it’s about a result that is not so obvious, as manufacturing a pipe rubber conveyor belt is an extremely delicate and complicated task.
When designing and later producing such an item, great attention must be put on realizing a belt that could be flexible enough to wrap itself around handled material. If not, the concerned belt would be too rigid, and it will not accomplish the task it has been projected for.
Only a perfect matching between a great knowledge of the rubber conveyor belt industry and skilled workers can ensure the manufacturing of such a great product.
The benefits of tubular conveyor belt
Among the main advantages that such a textile pipe rubber conveyor belt has provided to the end customer are several aspects to mention:
- no dust and material spillage in the environment;
- minimization of maintenance costs;
- no changesets in the city buildings structures as the conveyor system passes through the city thanks to an underground tunnel;
- reduction of energy consumption.

Application fields of Tubular Conveyor Belts
As claimed, pipe rubber conveyor belts can guarantee many special advantages that can be transversally used for different industrial applications.
It doesn’t matter which kind of product you are handling, the only thing you have to focus on is avoiding dust and material spillage,, relying on a high-tech item.
For this reason, tubular shape rubber conveyor belts can be installed and found in the following industries
- cement plants
- power plants
- port terminals
- steel making plants
These are only some, and perhaps the most recurrent industrial fields where it is highly probable to observe a tubular shape rubber conveyor belt working, assuring top level performances.
Rubber compounds
When designing a tubular conveyor belt, there are several options to choose depending on conveyed material characteristics .
Since these items handle various materials, withstanding different working conditions during the years technical department has studied and developed an important number of rubber compound options, matching with some of the most important international market technical requirements, such as:
- abrasion resistant
- heat and oil resistant
- fire retardant
Talking in detail, here below you can find a summary of what was just explained:
| RUBBER COMPOUND TYPE | SIG CODE | DESCRIPTION |
| ABRASION RESISTANCE | CL | Standard abrasion resistant degree – abrasion loss 150mm3 |
| EXTRA ABRASION RESISTANCE | EC | Extra abrasion resistant degree – abrasion loss 90mm3 |
| FIRE RETARDANT | BS | Self-extinguish covers (K degree DIN 22102) |
| FIRE RETARDANT & OIL RESISTANT | AG | Oil resistant and self-extinguish covers (G+K degree DIN 22102) |
| OIL RESISTANT | OM | Oil resistant covers (G degree DIN 22102) |
| HEAT RESISTANT | CX | Heat resistant covers for 130°C and peaks 150°C |
| HEAT RESISTANT | MX | Heat resistant covers for 150°C and peaks 180°C |
| HEAT RESISTANT | TX | Heat resistant covers for 200°C and peaks 300°C |
Technical specifications of the textile tubular conveyor belt
Another crucial point you must focus on is the one concerning technical specifications and conveyor system design.
It is necessary to respect the specific technical data, to manufacture a suitable belt for the concerned and delicate industrial application. Otherwise, there could be serious problems connected to the belt:
- flexibility;
- stability;
- tube rigidity.
So, it is extremely important to ensure that the item can wrap around handled material and get a tubular shape to perfectly execute its task..
Just read the following table to have an idea of what just told you:
| NOMINAL TUBE DIAMETER | INDICATIVE BELTH WIDTH | STANDARD IDLER SPACING | MINIMUM TRANSITION DISTANCE | MINIMUM CURVE RADIUS | MAX LUMP SIZE | MAX SPEED | VOLUMETRIC CAPACITY |
| mm | mm | mm | mm | mm | mm | m/sec | m3/h |
| 100 | 450 | 1,10 | 2,5 | 30 | 33 | 2,2 | 21,2 |
| 150 | 600 | 1,10 | 4,0 | 45 | 45 | 2,2 | 46,9 |
| 200 | 800 | 1,30 | 5,0 | 60 | 60 | 2,5 | 84,7 |
| 250 | 1000 | 1,45 | 6,5 | 75 | 75 | 2,5 | 132,4 |
