Application and Validity:

Type approved transit system for cable, pipe and bundle pipe in Class A divisions (bulkhead and deck). GK transits consist of GK metal frame and GK sealing system (modules and accessories halogen-free). GK transits meet the integrity and insulation criteria of the divisions. Max. operating temperature of the cable/pipe 90°C. All work is carried out in accordance with current welding and mounting instructions and should only be carried out by trained personnel, in compliance with legal regulations. For projects of the German Navy VG 88717 must be taken into account. Depending on the requirements, transits can be completely-, partially- or un-insulated. The regulations of the responsible flag state administration must be ob-served if necessary. Information, technical drawings, certificates, insulation instructions, training and inspections are available on request from Roxtec GmbH (technic-germany@roxtec.com or www.gkmarine.de).

1. Packing chambers: Measure & Prepare

Clean the frame and, if neces-sary, re-paint it (approx. 100 µm layer thickness).

Quick check of the chamber dimension with GK test mandrel (61.0; 121.0 or 181.0 mm) or suit-able measuring equipment.

Single frames and the outer chambers of the group frames in particular tend to warp due to the weld-ing process. Deviations from the tolerance should be eliminated before inserting the cables/pipes. If in doubt, determine exact values with suitable measuring equipment. For gas and water tightness, the tolerance of ± 1.0 mm must be observed.

3. Modules: Size & Diameter

Determine cable/pipe diameter e.g. with GK caliper gauge.

Check fit of both module halves on the lines. An approx. 1 mm gap between the module halves should not be compressible by hand. For gas and water tightness, the modules must not be selected too large or too small.

The „MPL“ module plates are suitable for 8 lines of the same size (7-11 mm) in a row.

Filling modules „FM“ and tween plates „ZWP“ fill the frame completely (max. FM-60/00 & RAM 60/00 allowed in transits with pressure requirements).

Select module halves: MH-15; -20; -30; -40; -60; -90 & -120 for Ø 2-108 mm with partially overlapping inner diameters.

4. Execution: Filling & Packing heightsBy filling the packing frames with modules, the certified fire resis-tance class (through additional fire protection insulation) and the compressive strength is guaranteed. Filling continues until the pack-ing height „H“ is reached. Two module halves „MH“ each seal one line. In case of pressure requirements, (gas and water pressure) only one block size should be used in each module row. If a large number of lines is required, four small „MH“ modules may be used in addition to large „MH“ modules (e.g. 2x40 & 4x20). Only here may the small modules be turned by 90° if necessary. The largest module in the row determines the height of the packing row. Filling modules „FM“ and tween plates „ZWP“ fill the frame completely. Each row ends with a metal anchor plate „VAS-Metal“. Without pressure require-ment, plastic anchor plates „VAS-HF“ can be used instead of metal anchor plates.

5. Frame: Finish & Tighten KADThe KAD is always secured between two „VAS metal“. Always use a „ZWP“ between frame and „VAS“!

The pre-press tool (VPH) reduces air gaps and further assembly is made easier. If mounting is interrupted, the VPH compresses the module rows and the anchor clutch (VASK) secures the modules when the VPH is removed. The VASK must be removed before further assembly.

One wedge seal KAD for each chamber width: KAD-60; KAD-120 and KAD-180 (untightened height = 40 mm).

Expose the wedges of the KAD and then carefully lubricate all sliding surfaces with GK mounting lubricant directly before assembly.

Push the KAD in completely up to the stop. The KAD must al-ways be mounted between two VAS. Beyond that, the position is arbitrary.

Tighten KAD nuts evenly (with wedge tool). Tighten the special nut tighten the nuts until stop, but each nut must be checked individually. Module offset max. 3 mm, modules must not rest on the VAS edge! The tightening procedure is OK when all visible gaps are closed, lines are firmly compressed between the module halves and GK mounting lubricant is pressed-out. Optimum tightness is achieved after 24 hours!

Disassembly & ModificationGeneral note:

The GK Packing System is a type-approved and safety-relevant element for shipbuilding and must be used accordingly. Initial installation puts the plastic material under considerable compressive force and distorts it to a degree in order to achieve the required fire resistance class and any required pressure resistance. Depending on the time, temperature and other environmental influences, material that has already been installed should not be reused in cases of uncertainty. Corrections to incorrectly installed transits must be made promptly after initial installation before the lubricant has dried and the installation shows signs of setting. For modification of the transits, the wedge seal must always be completely loosened and reset to the height of 40 mm (see following points). No care or maintenance of the GK Packing System is required. However, the system should be checked at regular intervals for com-pleteness, damage, corrosion or contamination with harmful substances such as oil, fuel, acids and alkalis, etc., which could impair the safety of the penet-ration. If necessary, the GK Packing System should be cleaned or replaced in order to restore its safe condition.

To open the packing chamber, loosen KAD nuts step by step and loosen the wedges of the KAD by hammer blows on the nut(s) until KAD is completely relaxed.

Use a flat object to lower the KAD plates from VAS or mod-ules, release KAD to 40 mm initial height.

Remove KAD and reuse it only if KAD is undamaged and in perfect condition. Faultless VAS metal are reusable!

For transits without pressure re-quirements: Fill the affected rows completely with new modules; with pressure requirement: fill the frame completely with new modules and accessories.

Lubricate the module halves; insert the lower half of the module into the frame, insert the upper half at a slight angle into the frame, apply slight pressure or short hammer blows.
