Insert blocks

The right insert blocks

Once the transit frames are installed, the cables and/or pipes that pass through them are kept securely in place by a sealing system that also prevents the spread of fire, smoke, hazardous fumes, water, etc. It is widely acknowledged that the most stable and safe form of sealing system consists of precision-moulded insert blocks of many different sizes that also provide the much needed application flexibility.

The stability and safety that insert blocks give to transits is derived primarily from two main features.

  • The very precise fit that modular insert blocks of different sizes achieve around cables/pipes to totally seal the space between them.
  • The toughness and robustness of the blocks, which do not deform over the long term.

These features make sure that not even gas can pass through a packed transit when it is installed correctly.

Safety

Cable and pipe transits must have features that make them safe in a variety of hazardous environments to protect people, property – including intellectual property like computer data – and to help ensure the continued operations of a business or other organization.

Frames

The design, materials, construction and finish of frames play decisive roles in determining the safety of frames in withstanding constant stress in maritime and land-based environments.

Cable management

Before working with insert blocks, cable management has to be carried out. Basically, this means that all cables passing through frames must have enough movement to allow them to be positioned correctly to facilitate fitting the insert blocks.

Professional installation

No matter how many safety features are built into the components of cable and pipe transits, they can only be realized through correct installation. This means that transits must be complemented with training to maximize the safety awareness in all stakeholders.

Testing and inspection

Testing for certification purposes is carried out in independent laboratories throughout the world. The Fire Test Procedure (FTP Codes) Standards, however, apply equally to all laboratories, no matter their location.
