RGP Ex System At Sea On land Ex EMC

These Ex cable and pipe transits are used in high-risk maritime, offshore and land-based environments to minimize danger by preventing the spread of fire, water, gas, chemicals and other hazards substances.

The system consists of a round rubber frame (RGP Ex) and rubber blocks. The RGP Ex system must be installed with a MCT Brattberg sleeve as a kit, and packed with rubber blocks suited for each cable and pipe dimension. The compression bolts are tightened to compress the rubber blocks against cables and pipes to establish a tight seal.

Benefits of MCT Brattberg Ex systems

  • Ex rated transit for hazardous environments
  • Assists cable management
  • Seals the penetration against the passage of fire, water, gas, sound and environmental hazards
  • Can be combined with special EMC modules and for Grounding and Bounding
  • Unlike other brands our system can be dismantled and re-used
  • Marked blocks for increased safety
  • No adaptation of standard blocks needed

Instructions

Ex

  • Available as both equipment and component

Component:
Component is not intended to be used alone and requires additional consideration when incorporated into other equipment or systems for use in explosive atmospheres (refer to IEC 60079-0)

  • All blocks marked with black or green marking.
  • Ex system combined with EMC has yellow marking on the front face (see EMC instructions) and black or green on the back.
  • MCT Brattberg RGP Ex system must be installed with supplied sleeve.

Correct and safe installations

To achieve the highest standard of safety, a cable or pipe transit must be installed correctly. As there are many different types of frame – which may be either welded, bolted or glued into position – and insert block, it is essential that installers known when to use the most appropriate installation method.

For more information, please view following instructions, videos or download manuals as PDFs.

 


PRESSURE-TIGHT INSTALLATION
RGP Ex All contact surfaces between the pipe and the RGP plug must be cleaned carefully prior to installation. Do not use any lubricant on these surfaces. All blocks must be lubricated carefully with MCT Brattberg lubricant. The penetration must not be subjected to pressure for at least 48 hours after installation. This is to allow the pressure to equalise throughout the penetration. It will take more time for the pressure to equalise at temperatures below 20°C.
Note: If the installation is subjected to pressure, all components must be replaced after removal and refitting.
