PART 2 PRODUCTS

2.1 MATERIALS

The type of materials which come in contact with the fuel shall be noncorrosive. No zinc coated metals, brass, bronze or other copper bearing alloys shall be used in contact with the fuel. Additional requirements are as follows:

2.1.1 Piping

Construct all pipe and piping components of Schedule 10S, Grade TP304L, stainless steel conforming to ASTM A312/A312M. Only seamless pipe will be used.

2.1.2 Fitting and Bends

Same thickness as adjoining pipe.

2.1.3 Components

Stainless steel.

2.1.4 Structural Steel

Structural steel shall conform to ASTM A36/A36M, hot dipped galvanized after fabrication and painted a factory standard color.

2.2 EQUIPMENT AND MATERIAL

2.2.1 Truck Fill Stand Pantograph Fabrication - (Non-Recessable)

a. Truck fill stand pantographs shall consist of three main sections, plus one connecting section and one dispensing end. Total length of the three main sections shall be 10 feet.

b. The dispensing end shall be designed to be coupled to the refueling truck at heights of 12 to 55 inches above the road.

c. The dispensing end shall be supported by an adjustable spring, weight device or hydraulically actuated cylinder to counter balance the weight of the pressure fueling nozzle, shut-off valve, flanged swivel joints and connecting pipes to ensure that only minimum force occurs when connecting pantograph to tank trucks. One person shall be able to operate the dispensing end. Pantograph shall be provided with a nozzle hanging support.

d. Hoses shall not be permitted as a part of the truck fill stand pantograph.

e. The three main sections of the pantograph shall be locked together when stored.

f. The overall electrical resistance between the flanged end and the pressure fueling nozzle shall not exceed 1 kilo Ohm. Grounding straps across the swivel joints are not permitted.

g. The pantograph shall be equipped with a permanent sampling, pressure gage, drain and vent assemblies.

SECTION 33 52 43.12 Page 4

h. The connecting section and the dispensing end shall be locked to the main sections of the pantograph when in the stored mode.

2.2.2 Flanged Swivel Joints

a. Anchor end, intermediate, and hose end pantograph swivel joints shall be stainless steel, single plane, flanged capable of rotating 360 degrees. Welded swivel joints and welding of swivel joints to the pipe and/or elbow is not permitted. Welding of swivel joints to flange joints is permitted. Swivel joints shall be of the non-lubricated, maintenance free type with non-lubricated bearings and no lubricating fittings.

b. No leakage shall be permitted under positive or negative pressure conditions. No leakage shall be permitted under high or low temperature conditions. The swivel joints shall be warranted for three years against leakage due to both positive and negative pressure conditions.

c. There must be electrical continuity from one flange to the other without the use of ground straps. The electrical continuity from one flange to another (without the use of ground straps) shall be less than 1000 ohms. Each swivel joint shall have at least two ball bearings and one roller bearing and two seals.

[*Am-2]

2.2.3 Not Used

2.2.4 Sampling Connection

Sampling connection shall be provided. Materials shall be Type 316 stainless steel. Material for ball valve, quick disconnect coupling shall be Type 316 stainless steel. Each sampling connection shall consist of a 1/4-inch sampling probe where the probe faces upstream, ball valve, a quick disconnect coupling and aluminum dust cap. The sampling connections shall be capable of accepting a sampling kit for drawing the samples required to assure fuel quality. Provide a 3-foot, fuel resistant sampling hose with mating quick disconnect fitting.

2.2.5 Pressure gage assembly

Assembly shall consist of 4-inch ASME B40.100 pressure gage and pressure gage stop cock. Pressure gage shall be liquid filled type with an indicating range 0-275 psig. Material shall be Type 316 stainless steel.

2.2.6 Drain and Vent Assemblies

Assemblies shall consist of a 1/2 inch ball valve and shall terminate with a 180 degree pipe gooseneck and screwed cap for the vent, and the drain shall have a 1/2 inch ball valve and shall terminate with a cam type quick disconnect.

2.2.8 Dry Break Quick Disconnect

A 3-inch semi-dry break quick disconnect (MIL-DTL-24788, Class 1 or equivalent) shall be mounted between the shut-off valve hose end and the pressure fueling nozzle. The semi-dry break quick disconnect shall be capable of swiveling through 360 degrees and shall incorporate a 60 mesh strainer in the portion attached to the pressure refueling nozzle (also known as the male half).

[*Am-2]

2.2.9 Pressure Fueling Nozzle

SAE AS5877, 2-1/2-inch nozzle D-3 [Text Deleted] shall be provided for the connection between pantograph and aircraft. Design shall be for single point fueling of truck at a flow rate of 600 gpm with maximum pressure drop of 30 psig. Nozzle shall be provided with a permanently installed quick disconnect sampling coupler. (Gammon GTP-235-3/8 Jet Test QD meets this requirement.) Provide pressure gage with 0-100 psig indicating range mounted on actuator for use with quick disconnect sampling coupler.

2.2.10 Aviation Fuel Hose

Fueling hose shall conform to EI 1529, Grade 2, Type C, semi-hardwall, 3 -inch nominal hose designed for use with specified fuel for a working pressure of 300 PSIG over a working temperature range of -22 to 131 degrees F. Hose shall be constructed of braided synthetic cord surrounded by an interior rubber tube and an exterior rubber cover. Provide permanent brass, threaded, male NPT, both ends.
