To determine the length, divide the available head of the pumping station by the friction loss per mile for the specific tubing at the specified design flow rate. This is a dual-axle trailer with four bolster attachments and an adjustable tow boom Figurepage 8. The petroleum group, assigned to the theater army, is the major Army petroleum operator for the theater.
These sections can be recovered later if they are not used. Bulk fuels are transferred by pipeline to tank farms. This is the standard te mperature for both design and operation of military pipeline systems.
It is intended for flood, transfer, and general utility service.
Each pumping-station set differs slightly in its capabilities and component listings. It is used to pull the 4-ton bolster trailer, to transport pipe to the construction site, and to haul valves, couplings, and soldiers to and from the construction site.
Locate the next pumping station FigureStep 3page using the original hydraulic gradient triangle. Grooved pipe is available in standard- weight and ligh tweight stee l and lightweight aluminum.
Pipe Length Equivalents for Pipe Fittings. If properly installed, the thermal-relief valve discharges small quantities of fuel through the ffm hose to relieve the pipeline of pressure buildup. DA prescribes supply levels for the theater army in terms of days of supply.
FM Chptr 2 Equipment
The total friction loss must be no greater than the 54-82 allowable 18 feet of head. Many minor changes must be made to effectively use the available skills for a specific job or project.
The route will determine construction time, effort, and material requirements in either a positive or negative manner.
Each pup joint must be cut and grooved on each end, which takes a trained operator about 60 minutes. The pipeline system extends f far forward as possible, usually into the corps’ storage sites.
Coupling is a time-consuming and strenuous task. Stations on Equal Elevations. Based on the planning considerations, a fuel-supply planner will consider using either a hose-line, coupled, or welded pipeline system. Poor Locations for Pumping Stations. A pipeline should be diverted around difficult terrain such as marshes, swamps, or land subject to periodic flooding. Draw the altitude AB of f, triangle to the same scale as the vertical scale of the pipeline profile in Figure Stations on a Downgrade.
Military Petroleum Pipeline Systems (FM 5-482)
Check valves and gate valves are the most commonly used valves along a pipeline. Pipelines are used as far forward as the corps’ rear area.
The natural state of the pipeline route should be left as undisturbed as possible.
Most mainline pumping-station kits include two pumping units to facilitate a hour operation. Dynamic head is greatest at the ground level where the flow changes direction and the streams begin to rise in the air. Determining if a rising-stem valve is open or shut is easy. When the fn stops and back pressure develops, the clapper is pushed against its seat, stopping back flow.
The normal design head capacity of each pump unit is 1, feet. Mark the point on the pipeline profile where the bottom edge of the scale first passes through mf pipeline profile Pi. The viscosities of military fuels are found in Appendix C or 54-82 federal specifications. A set consists of towers; guy wires; deadman anchors; main cables, suspenders, and cross bearers; staging board; tension cables; wind guys; and hand rope needed to f the bridge.
Because elevation affects atmospheric pressure, pump engines are affected at elevations above 3, feet, and design loads on pumps are decreased about 4 percent per each 1, feet above 3, feet. Planning starts before the actual operations at the TO and theater-army levels. These are spec ially designe d clamps used to repair leaking pipes or couplings, temporarily.
In industrialized areas, initial 5-4882 could be obtained locally. Other sizes can be designed and manufactured.
In FigureStep 2, page the scale F to G is the safe-working -pressure scale for 6-inch standard pipe 0. The US Navy is responsible for the installation of the Offshore Petroleum Distribution System OPDS and ship-to-shore pipeline to the high-watermark and the connections and operation of the beach-termination unit. To couple pipe sections 5-4882, groove the pipe ends to facilitate a coupling and gasket assembly. This pipeline engineer company’s primary mission is to support the engineer battalion in the construction and rehabilitation f pipeline systems and facilities.
Hose lines or coupled pipelines initially carry the products inland, and the Army transports the fuels to the ground forces, where possible. Viscosity in stokes m ultiplied by sp ecific gravity equals viscosity in poises.
