A characteristic attribute that guarantees the complete sealing of a cable or pipe

We spoke with Antonio Alonso, HTS Product Manager, about this unique feature that we find in the Hawke Transit System sealing blocks.

Hello Antonio. Could you tell us what is the function of the so-called 5 sealing faces?

 The 5 sealing faces function as 5 differentiated sealing points within the compression system where the block grips the cable. This structure of the blocks provides a great adaptability of these to the different cables or pipes and gives our system a lot of flexibility when choosing the blocks for sealing a certain cable or pipe.

How do they act?

These 5 sealing faces act in two ways.

 1º In the event of a possible leakage of fluid elements such as water or gas, each time these elements face one of these sealing faces, they make it difficult for them to pass through.

2º They adapt perfectly to the shape of the cable or pipe. The grooves inside the block allow the 5 sealing faces to deform as necessary to adapt to all the irregularities that the cable or pipe may present, since as we know many cables and pipes do not come perfectly smooth.

This structure of the blocks provides a great adaptability of these to the different cables or pipes and gives our system a lot of flexibility

Do they guarantee total tightness?

Absolutely. Our blocks guarantee the total tightness of the passage.

What material are these blocks made of and why?

These blocks are made of a type of intumescent polymer, free of halogens, which in case of fire guarantees their integrity and the safety of all personnel who are in a close radius. This composition prevents them from releasing toxic fumes that are potentially harmful to health.

In summary, our blocks have a structure and composition governed by the highest quality standards and guarantee the total tightness of the transit, protecting both the assets of our clients and the lives of the personnel.
