Squeezer CTT

Fire rated transit for cables and plastic pipes

The Squeezer CTT is a completely new design, a patented transit for cables and plastic pipes in marine applications

The transit consists of steel tubes rolled into a steel plate, which in turn is welded into an opening made in a deck or bulkhead. Cables or plastic pipes are drawn through the tubes, which are coated on the inside with an intumescent material. In the event of fire the coating swells and forms an effective seal against the flow of fire, smoke and gas.

Technical Data

Area of Use

The Squeezer CTT can be used for cables and plastic pipes penetrating fire rated walls, bulkheads and decks both below and above the maximum flooding surface.

Sealing Modules

The Squeezer CTT is supplied as standard modules, ready for welding into position.

Sizes and Numbers of Penetrants

Cables or pipes with diameters up to 45 mm can be drawn through a tube. In addition, several cables or pipes with smaller diameters can be drawn through the same tube. It is, however, important not to overfill the tubes since the final silicone end seal could then be difficult to apply.

Final Sealing

In order to prevent the flow of cold smoke and gas, and to withstand water pressure, each tube is sealed at one end with Firestop Sealant 3000, a fire rated, flexibel silicone sealant. The application of sealant is carried out in conjunction with the cable or pipe installation. Fire Stop Sealant 3000 is supplied in standard cartridges containing 310 ml. Approx. 40 ml will be required for an empty tube.

Insulation

The prescribed heat insulation of the bulkhead or deck should be extended over the Squeezer CTT plate.

Installation Directives

  1. Establish the number and size of cables/pipes which are to penetrate the division.
  2. Determine the number of Squeezer CTT tubes required. Do not overfill individual tubes. See the Ready-Reckoner for the maximum number of penetrants in a single tube.
  3. Determine the suitable Squeezer CTT module configuration.
  4. Cut a suitable aperture in the division. The size of the aperture should be equal to the size of the plate less 20 - 40 mm.
  5. Position the Squeezer CTT against the division with the longer parts of the tubes protruding at the insulated side of the division. Leave the protective plastic caps in place for the present.
  6. Weld the plate in place using an approved welding method. Inert-gas are welding is preferable to avoid undesired heating of the tubes' intumescent fire protection coating (tube temperature above 120"C should be avoided). Suitable consumables are: SMAW FCAW AWS 7016, AWS 7018 AWS E-71-T5, ESAB P48S or equal Filletjoint weld with a throat thickness (a) of approximately 2 mm. Preheating to avoid hydrogen cracking and welding method to follow structure welding instructions.
  7. Restore primer destroyed by the welding. The final coating can be of any type and colour of paint. Remove the label's protective film. Remove the protective plastic caps from the tubes.
  8. Pull the penetrants (cables or pipes) through the tubes.
  9. Seal one end of each tube to obtain gas- and watertightness with Firestop Sealant 3000 to a depth of approximately 20 mm. Use aluminium-silicate blanket as a backing to the sealant. Spread the sealant evenly over the surface with a spatula or a finger moistened with soapy water.
  10. Seal empty (reserve) tubes as in point 9.
  11. Leave the sealant to cure for at least 24 hours; complete curing is attained after c. two weeks.
  12. The prescribed heat insulation of the division should be extended over the sealing plate and between the individual tubes.

PIPELOCK

Pipelock sleeves are used around plastic pipes that penetrate "fire cells" - rooms or areas that are designed to resist fire. Manufactured from a high-quality, fire resistant, composite plastic, Pipelock resists corrosion and when burnt emits very little smoke.

An intumescent material inside the sleeve expands when affected by fire, putting pressure on the pipe it surrounds, sealing any gaps and preventing the spread of flame, smoke or gases into the protected cell.

ADVANTAGES

Easy installation. Maintenance free. Able to withstand severe weather conditions. Suitable for most sizes of plastic pipes. Approved by Lloyd's Register of Shipping, Det noske Veritas and Registro Italiano Navale.

FUNCTION

When a Pipelock is affected by fire the intumescent material within the sleeve is activated. At temperatures of 100 - 150"C this material expands to up-to 8 times its installed size, exerts a pressure of up-to 5 bar, and effectively seals the hole between the pipe and the barrier it penetrates. As heat increases, the surface layer of intumescent material forms a fire-resistant char preventing the passage of flame and gases.

INSTALLATION

The Pipelock sleeve is manufactured in two parts that fit easily together using stainless steel cleats. The sleeve can be fitted onto the surface of walls, bulkheads or decks or embedded within them. It is fixed in place with non-combustible screws or held in place by weld-on clamps.

To safe-guard against the passage of cold smoke or gas, any joint between the pipe and the sleeve is sealed with Fire Stop Sealant 3000.

TECHNICAL DATA

ORDERING

When ordering, please specify:

Firestop Sealant 3000 consumption:

Approx. 20 mi sealant per running meter of bead measuring 6 x 6 mm. Additional sealant may be needed if the pipe O.D. is substantially smaller than the Pipelock

INSTALLATION DIRECTIVES

  1. Determine which size of Pipelock sleeve is needed.
  2. Hold the two halves of Pipelock in place around the pipe. Mark the screwholes through the flange and onto the partition.*
  3. Remove the two halves of Pipelock and drill the holes for the screws.*
  4. Assemble the two halves of Pipelock around the pipe and fix them together using the sliding cleats.
  5. Bolt Pipelock to surface using four screws or bolts made from noncombustible material.*
  6. Apply a bead of Fire Stop Sealant 3000 to Pipelock flange where it meets the partition, to the joint around pipe and Pipelock and also between pipe and partition at the opposite side.

* The Pipelock can be weld fixed onto the partition using four stainless steel clamps as an alternative to screws. Such clamps are provided on request.
