Kajiramar This valve has a gate disc or wedge that is opened or closed to control fuel flow. This set contains the special size equipment, in the correct quantities, required for handling the 4- 6- and 8-inch pipe at stockpiles, pipe sections, and laying and welding the pipeline. Military Petroleum Pipeline Systems FM Repairing a leaking or broken pipeline can be extremely hazardous and life-threatening. When stringing aluminum pipeline, expansion loops must be laid out for at least every 1, feet of pipeline.

Because of ffm critical position, the station and the connecting f to the tank farm require careful planning and design to ensure that sufficient suction pressure is provided to the first mainline pumping station under design-flow conditions.

We use cookies to give you the best possible experience. Locating a pressure-reducing station g. This is the standard te mperature for both design and operation of military pipeline systems. Theoretical suction-lift values for military fuels 2 Flow Velocity. Head Capacities of Pumping Units. The hydraulic gradient triangle is a right triangle that is constructed on the same scale as the profile. Federal specifications list cm properties of these fuels Table page shows the gravity range of the most common military fuels.

This occurs most often on long downhill slopes during very cold weather because of pipe contraction. Emergency head capacity se d Table 1 page of a pumping unit is the total head against which it will pump to provide maximum pipeline capacity. Overcoupling- leak clamp Figure Fk hinged snap-joint coupling, which is standard for single-grooved aluminum pipe, is available with either a one-piece separate gasket rm a two-piece integral gasket Figure Pipeline markings B Figure B However, access for vehicles during the stringing operations could be a problem, making the power- line route unusable.

Volume and API gravity increase with temperature while density, specific gravity, and viscosity vary inversely. Viscosity is a measure of the flow of a liquid. Looking for beautiful books? However, welded military pipelines can operate at higher pressures. The total friction must be no greater than the maximum allowable 18 feet of head. However, because these assemblies are preassembled with valves and scraper passage signals and are skid-mounted, they are more readily installed and simpler to operate and maintain.

Table lists suggested stake colors for various types of installations. Tank vehicles, rail tank cars, and hose lines are used to move bulk-petroleum products from general-to- direct-support echelons. Total friction loss Appendix C. Different pump units exist for an aluminum pipeline system and a steel pi peline system. Fk Chapter 2 for operating characteristics on pump units. The initial will probably consist of the TPT, portable pumps with capacities of and gallons per minute GPMhose lines, and collapsible storage tanks.

The valve is supplied as part of the fuel-dispensing assembly. This profile is used to locate pumping stations, pressure-reducing stations, and other pipeline installations.

Pipeline capacity throughput is the quantity of fuel pumped per unit of time. Inspect all hose lines for dry rot. Pipeline suspension-bridge assemblies are available in, and foot kits. Each pup joint must be cut and grooved on each end, which takes a trained operator about 60 minutes. In dense areas, the pipe sections cannot be aligned, and the construction crew has insufficient working space unless a lane is cleared through the areas.

However, coupled pipelines are vulnerable to sabotage and normal damage and wear. If possible, the pipeline components, which require forklifts or cranes to be moved, should be transported directly from the ship-to-ground transporters. Generally, when this triangle is applied to the pipeline profile at the same scale, with the right angle corner on the location of one pumping station and with the base parallel to the base of the profile, the point at which the hypotenuse hydraulic gradient or its extension intersects the profile is the maximum distance to the next pumping station.

Suppose, because of the terrain, that station 4 is at a higher elevation than station 3. It all of the tools required for operator maintenance and repair of the standard pumping units and the 4- 6- and 8-inch pumping-station manifolds.

Bulk fuel is moved from base terminals and rear storage locations to the cm zone, using flexible hose lines. This is a portable machine used to cut and gm nonstandard lengths of aluminum or steel pipe.

For more information, see FMs and Using cross-country cutoffs can be beneficial where primary roads wind FM excessively and if the time and material savings are consistent with extra construction and maintenance effort required.

This slope represents the loss of head per unit length of pipeline and establishes the gradient for determining station spacing.

Pipe fittings for aluminum pipe 3 Culvert Pipe. The pumping- station locations selected using the hydraulic-gradient-triangle method may not be suitable for many reasons. The boiling point varies; at high altitudes, liquids boil at lower temperatures than at sea level. Pumping stations should operate at maximum head capacity only during critical tactical emergencies.

The maximum unsupported span of steel coupled pipelines should not gm 40 feet. TOP 10 Related.

Kajizragore See Table page for the design capacity for this pump. However, welded military pipelines can operate at higher pressures. The proper suction pressure must be restored at the succeeding pumping station. From this point Bi, draw a line on the profile parallel to the hypotenuse of the hydraulic gradient triangle. Approximate pressure loss through lubricated plug valve equivalent feet of pipe Table These valves are used in pipelines to cut off, control, and direct the fuel flow in the line. You can redesign by replacing the aluminum coupled pipe in the high-pressure segment of line with standard welded pipe. It supervises two or more petroleum-pipeline and terminal-operating battalions, transportation motor transport battalions petroleum, oils, and lubricants POLand other units, as required.

Shakarr Lighter pipe, used in low-pressure pipelines, is easier to construct, and it avoids the mechanical failures inherent at higher pressures. Standards for pipeline welds B Figure B The ball valve is not used in mainline pipe systems because scrapers cannot pass through them. So line scrapers can pass, a check valve must be opened to the full diameter of the pipe when used in the line between pumping stations. If clearing and leveling are required, they must mark the route in advance. From this point Bi, draw a line on the profile parallel to the hypotenuse of the hydraulic gradient triangle. Dynamic head is a measure of pressure, or kinetic energy, of liquids in motion.
