considerations. The hoseline arrangements shown are example layouts. Other arrangements may be more suitable for
certain situations.
2-6.3 Switching Manifolds (1 Set)
NSN 3835-01-210-5593
a.
The switching manifold provides the means of controlling flow between the fuel modules, the contaminated fuel
module and the associated pipeline. Valving in the switching manifold allows cuts between batches of different
fuels arriving at the TPT from the associated pipeline, with the product interface going into the contaminated fuel
module.
b.
The switching manifold consists of one 25-piece bundle (475 ft.) of aluminum pipeline sections (Fig. 2-36 and
para. 2-5.2), one crate (25 ea.) of double groove coupling clamps (Fig.'s 2-37A, and 2-378), nine 6-inch
aluminum gate valve assemblies (Fig. 2-54), nine 6-inch aluminum double groove tees (Fig. 2-55), and one
sampling assembly. The sampling assembly is covered as a specific item in paragraph 2-4.8 and Fig. 2-22.
c.
Ideally, the switching manifold should be as compact as possible, however, certain situations may require extra
length.
d.
The meter strainer, MS1H, is located in specific site technical manuals or by field instruction.
2-6.4 Transfer Hoseline Assemblies (3 Sets)
NSN 3835-01-210-5613
a.
The transfer hoseline assembly provides the connection between the switching manifold, the secondary tank
farm modules, the primary tank farm modules and the return manifold to the pipeline system. Valve assemblies
in the transfer hoseline allow the switching of product between the fuel modules.
b.
The transfer hoseline assembly consists of approximately 2.75 miles of 6-inch lightweight collapsible hoseline
(Fig. 2-30), one 6-inch aluminum wye assembly (Fig. 2-39) and two 6-inch aluminum cross assemblies (Fig. 2-
38).
c.
The hoseline is provided in flaking boxes, with two 250 ft. lengths connected by a swivel coupling, per box.
Three flaking boxes can be stacked on the bed of a truck (may vary according to truck type and terrain) and
flaked out continuously.
d.
Note the location of the cross and wye assemblies relative to the secondary tank farm modules (Fig's. 2-63A and
2-63B) and the plot plan of secondary tank farm modules (Fig's. 2-38, 2-48, and 2-58). The proper placement of
these assemblies is very important to insure the layout of the secondary tank farm modules can be done
properly.
2-6.5 Fuel Dispensinq Assemblies (3 Sets)
NSN 3835-01-211-6835
a.
The fuel dispensing assembly is the means of issuing petroleum products from a TPT. There is one fuel
dispensing assembly for each of the three fuel units. Using a primary tank farm module as its pumping source
and bulk holding point, the fuel dispensing assembly allows fuel distribution to many users simultaneously.
