What is the meaning of Pipeline? Concept and Definition of Pipeline

Pipeline – Its Definition and Concepts 


Concepto de Pipeline

1. Concept of Pipeline

Pipeline or pipeline transport is the transport of goods through a pipe. Most commonly, liquid and gases are sent, but pneumatic tubes that use compressed air can transport capsules solid also.

Gases and liquids, any chemically stable substance can be sent through a pipeline. Therefore sewage, slurry, water, or even beer pipelines exist, but without doubt the most valuable are those crude oil and transportation of refined petroleum products including fuels: oil (pipeline), natural gas (gas supply), and biofuels.

Types of transport function


In general, the pipes can be classified into three categories depending on the purpose:

Collection of pipes

A group of small interconnected pipelines forming complex networks with the purpose of carrying crude oil or natural gas from several near a Wells processing facility or treatment plant. In this group, pipelines are short-generally, a couple of hundred metres and with small diameters. Underwater pipelines collection of product of deep water production platforms are also considered gathering systems.

Pipeline transportation

Mainly long pipes of large diameter, mobile products (oil, gas, refined products) between cities, countries and even continents. These transport networks include compression stations several gas lines or crude and multiproducts pipelines pumping stations.

Distribution pipes

Composed of several gas pipelines, interconnected with small diameters, used to carry products to the final consumer. Sections of link for the distribution of gas to households and businesses downstream. Pipes in the terminals of distribution of products to tanks and storage facilities are included in this group.

Operation


Field devices are instruments, data collection and communication systems units. The instrumentation includes flow, pressure and temperature / transmitters and other devices to measure the relevant date in required. These instruments are installed along the pipe in some specific places, such as injection or childbirth, (liquid pipe) pump stations, compressors (gas) stations and stations of valve block.

The information measured by field instruments gathered then on premises units terminals remote (RTU) that the field data transfer in a central location in real time using communication systems, such as satellite channels, microwave, or cellular phone connections links.

Pipes are controlled and operated remotely, from what is generally known as the main control room. In this Center, all data related to the field measurement is consolidated in a central database. The data are received from multiple RTUs along the pipe. It is common to find RTUs installed at each station along the pipe.
The SCADA system for pipelines.

The SCADA system in the main Control room receives all the field data and presents the pipeline operator through a set of screens or man-machine interface, showing the conditions of operation of the pipeline. The operator can control the hydraulic conditions of the line, as well as send commands operation (opening / closing of valves, turn on / turn off compressors or pumps, set points of change, etc.) Through the SCADA system for the field.

To optimize and ensure the operation of these assets, some pipeline companies are using what is known as advanced applications of pipelines, which are software tools installed on the upper part of the SCADA system, that provide greater functionality for the detection of leaks, leak location, tracking of batch (liquid lines), pork, follow-up monitoring of the compositionthe predictive modeling, look at the modeling future, training of operators, and much more.

2 Meaning of Pipeline

Pipeline is an English term which can be translated as "pipe". Although not part of the dictionary of the Real Academia Española (RAE), the concept is used in our language to refer to a computing architecture.
These virtual pipes are created to segment data and, thus, increase the performance of a digital system. It's an architecture based on the operation of pipelines, which are segmented into different branches and who have pumps to advance, in every way, the gas.
In computer science, the pipeline is used in microprocessors, graphics cards and software. Calculations carried out in the programming process must be synchronized with a clock to avoid the most ornate sections that are detected between two records.
Segment estimates, therefore, enhances the working frequency. This type of data flow means that the output from one phase is one entry from another. Thus, the various sections or phases is chained in the manner of a pipe, and streamline your workflow through this pipeline.
Typically, the implementation of these elements to develop in parallel, which makes it appealing to a buffer (a type of storage) when the elements are in consecutive positions.
It can be differentiated between pipelines without a name (which operate on a temporary basis and are deleted when not in use) and pipelines with name (created in the file system, to facilitate the communication of the various processes that appeal to the pipe in question).

3. Definition and what is Pipeline

In computer science, a pipeline or pipeline is a set of elements connected in series, data processors where the output of an element is the input of the next. The elements of the pipeline are usually executed in parallel, in those cases, storage must be type buffer inserted between elements. In computer science, pipeline is synonymous with segmentation. For more information see: segmentation.

Pipelines applications in computer science


1 Graphics Pipelines, are found in most graphics cards, consists of multiple arithmetic units or complete CPUs that implement various scenarios of typical operations of rendering, for example, calculations of light and colors, rendering, perspective projection, etc.

2 Pipelines of software or pipes, consists of multiple processes arranged so that the output from a process stream feed the input of the following process. For example, the Unix pipelines.
