Before trying to apply knowledge of pipelines on practice, one should carefully study the theory of this modern technology to be sure about its advantages and disadvantages.
So, what is the general notion of pipelines?
Pipelines are devices that are used for transporting liquids, gases and solids.
What is the elements of construction of pipe lining?
Pipelines consist of interconnected straight sections of pipes, pipeline components, valves and control valves, instrumentation, automation tools, supports and hangers, fastening materials (bolts, studs, and nuts), gaskets and seals.
What is pipe lining in a broad sense?
Pipe Lining is the simplest scheme requiring no power source view of active protection, since the pipeline is electrically connected to the source of traction rails from stray currents. The source of the protective current is a difference between the pipe-rail potential, resulting from the work of the electrified rail transport and availability of stray currents field.
What are the parts of design scheme of drainage protection?
To efficiently perform pipe lining operations, one should carefully study a design scheme of drainage protection:
1 – pipeline,
2 – device protection from the maximum currents
3 – polarized element
4 – current control device
5 – ammeter shunt
6 – rail network of electrified railway.
How is drainage protection generally performed in local areas?
Current control in the drainage circuit is carried out in the chain of resistance change by switching the active resistors. Keep in mind that drains are available by tens to hundreds of amperes.
Drainage protection may be connected to the network itself only to the midpoint of travel choke-transformers in two on the third throttling point. More frequent connection is allowed if a special protective device is included in the drainage circuit.
The project documentation and hp printer problems technical literature represents the following names of the individual components of the pipeline:
Line – section of the pipeline, interconnecting devices, installations, workshops and other line devices, installations, workshop;
Node– the line pipe, consisting of several elements assembled together on the detachable and non-detachable connections.
Units are divided into:
*flat, consisting of several elements located in the same plane;
*spatial consisting of several elements, arranged in two or more planes.
Element – a part of the pipeline to be independent manufacturing; it consists of bent portions or straight pipes and components, which all joints are made with an automated welding.
Detail – an elementary part of the pipeline, which has no connections, such as removal, flange pipe section, tee, cap, jump, as well as individual products included in pipeline construction – hardware, joints, valves, bearings, suspension and others.
What pipelining equipment is useful and necessary for effective performance?
Centralizers for connecting pipes for welding
Machines for cutting tubes and edge preparation
Furnaces for calcinations and storage electrodes and flux
Tools for pipe installation
Vacuum traverse
Complexes for cold bending of pipes in the field
Heat-shrinkable insulation materials for pipes
Heater joints welded pipes
lifting equipment
Tent welder
