1. SCOPE

1.1 Scope. This standard covers standard methods for swage tubes, stuffing tubes, and kickpipes on surface ships and submarines.

1.1.1 Application. These installation methods are to be used by all installing activities. These methods do not identify ship or type, but do establish minimum standards of acceptance for Naval ships. It is the responsibility of the user activity to determine which method satisfies their requirements. It does not authorize relaxation of any requirement specifically invoked by new construction, conversion, overhaul, or refurbishment contracts. In instances where deviated design requirements (for example, ship type, ship class, and so forth) conflict with the requirements of this standard, the requirements of this standard govern. Any deviation for electric plant installation identified in this standard is to be submitted to NAVSEA 05Z3 for resolution.

2. APPLICABLE DOCUMENTS

2.1 General. The documents listed in this section are specified in sections 3, 4, or 5 of this standard.

3. DEFINITIONS

3.1 Collective protective system (CPS). CPS is a system designed to inhibit the entry of chemical, biological, and radiological contaminants into collective protection zones on board ships. A collective protection zone is a section of the ship, which is defined by a physical boundary that inhibits the entry of CBR contaminants into the zone. A total protection zone is pressurized to 2 inches WG and its supply ventilation air is continuously filtered to remove chemical vapors and CBR particulate and aerosols.

3.2 Community stuffing tube for bulkheads. Community stuffing tube for bulkheads is a system of passing multiple cables through ballast tank bulkheads on submarines.

3.3 Kickpipe. Kickpipe is a pipe welded into the deck with a stuffing tube attached. Kickpipes provide protection of electrical cable at deck penetrations and are used to clear an obstruction or preserve alignment.

Kickpipes may be aluminum, steel, stainless steel, or brass to suit the installation or standard pipe sizes to suit the required stuffing tube.

3.4 Metal stuffing tube. Metal stuffing tube is a system of passing single electrical cable through decks and bulkheads and entering enclosed equipment on Naval ships. Metal stuffing tubes are manufactured in accordance with MIL-S-24235. Stainless steel is an alternative material which should be considered for use in applications highly susceptible to corrosion.

4. After the cables are properly secured, plastic sealer (electrical insulation MIL-I-3064, Type HF) shall be used to seal the space around the cable within the gland nut, and also within the open end of stuffing tubes, after the tubes are packed.

5. Stuffing tubes with insufficient clearance for passing cables may be reamed in place, not exceeding 0.031".

6. Many thermosetting plastic ingredients have poor shelf life. It is recommended that activator and hardener over three months in storage be discarded and replaced.

7. Instructions contained herein are intended for use with presently installed tubes where it is necessary to:

a. Replace existing cables

b. Install undersized cables

Instructions:

1. Type 1 (see figure 3A11):

a. Both ends of tube may be packed with prefabricated packing in accordance with MIL-DTL-16685.

b. Both gland nuts shall be tightened to give the prefabricated packing an initial set. Then the gland nuts should be removed and a split gland ring (Method 3A-11-3) added to each end of the tube.

c. Both gland nuts shall be tightened. For cables with a minimum outside diameter, where the gland nut cannot be sufficiently tightened, additional split gland rings (Method 3A-11-3) may be added to each end of the tube. The gland nuts in the final tightened position shall have the undercut and 2 or 3 threads exposed.

2. Type 2 (see figure 3A11):

a. The tubes should be installed in the bulkhead with the air relief screw on the top and the 90-degree ⅛"

I.P.S. fitting on the bottom.

b. Same as 1(a) above.

c. Same as 1(b) above.

d. Same as 1(c) above.

e. With the air relief screw backed off and using a lever operated lubricating gun with a flexible hose, fill the center position of the stuffing tube with sealing compound. See table 3A1-I for material. When sealing compound exudes from the air relief screw, secure the screw and continue the sealing of the stuffing tube with an additional eight to fifteen strokes of the lubricating gun. The additional strokes are to make certain that the center portion of the tube is completely filled with the compound. Free or excessive leakage of the sealing compound around the gland nuts indicates that the tube has been improperly packed. Where this occurs, the tube end must be repacked.

FIGURE 3A1. Passing cables through pressure-proof bulkheads – submarine instructions for packing stuffing tubes manufactured in accordance with drawing 9000-S6202-73899 (figures 3A11 and 3A12).

Instructions (continued):

3. Type 3 (see figure 3A12):

a. Same as 1(a) above.

b. Same as 1(b) above.

c. Same as 1(c) above.

4. Type 4 (see figure 3A12):

a. Same as 2(a) above.

b. Both ends of the tube shall be packed with a single ring, butt ended tight of flexible metallic packing

(Navy symbol 1430) forced tightly into place, followed by one ring of sealing packing (MIL-DTL-16685, Composition B) and one tapered ring of retainer packing (MIL-DTL-16685, Composition A). These packing rings shall be set up tight using the spacer sleeve, which provides the cavity for the sealing compound. The purpose of the packing up to this point is to seal off the space around the cable within the pipe extension to prevent entry of the sealing compound.

c. Same as 1(a) above.

d. Same as 1(b) above.

e. Same as 1(c) above.

f. Same as 2(e) above.

5. General instructions (all types):

a. With gland nuts, rings and packing sets in place, care must be taken to properly guide the cable through the tube to prevent damage or injury to the packing sets.

b. On cables where the initial clearance between the packing set and the armor is not sufficient to allow the cable to be pulled through the stuffing tube with the packing set and gland nut in place, the packing sets may be stretched and the gland nut, ring, and packing allowed to ride free on the cable until the cable is pulled into position. The packing set may be stretched by the use of a smooth tapered rod.

c. Where welding room is available, installation shall be the same as Types 1 and 2. If backing plate is necessary, it shall be the diameter of the tube plus 1", thickness 3⁄16".

d. Welding shall be in accordance with NAVSEA T9074-AD-GIB-010/1688.
