Is Piping and pipeline similar? Check now!

In the oil and gas industry, you will find many similar terminologies but have a wide variation in usage and functionality. Today, we will discuss one of the critical concepts and the variation in the functionality. Yes, you read it right. It is the Piping and Pipeline confusion. If someone asks you, what is the difference between Piping and pipeline, there are significant possibilities that you might tend to say these are similar. But let’s clarify these fundamental differences between the pipeline and piping terminology. This is a must-to-known topic in the oil and gas courses for mechanical engineers.

Piping and Pipeline definition 

The pipeline is a long chain or series of bigger diameter pipes usually found underground with fittings like valves and pumps to control the flow of large amounts of fluid carried over long distances.

Piping is a network of pipes confined within a specified boundary or space in an oil and gas plant that also has valves and fixtures to control the flow of fluid from one facility to another but within the specified boundary of the plant as and when required. If you are taking an online course for piping engineering, never skip these essential topics.

Also, Pipelines are of larger diameter so that they can easily transport bulk liquid or gas from one place to another, sometimes thousands of kilometers. But Piping can be from ½” to 80” depending upon the plant design requirements to transfer fluid, usually from one equipment to another within the plant boundary.

Pipeline Piping
Specification: Design Code for Pipeline is specified in ASME B31.4 for liquid transportation systems
& in ASME B31.8 is about the pipeline for gas transmission and distribution piping systems
Specification: ASME B31.3 is process piping code, and ASME B31.1 is for power piping.
Construction drawings for pipelines are termed alignment sheets.Construction drawings for piping are termed isometric drawings.
Pipelines travel thousands of kilometers to transport fluid from one facility to anotherPiping is a complex network of pipe and fittings within the confined premises of the facility or plant.
A pipeline can travel over the ground, underground and underwater.The Piping facility is mostly over the ground with a few underground services.
The pipeline system has a small supporting group of valves, pumps, and instruments to transport fluid with highest safety over long distances.A Piping system has an army of supporting equipment for effective functioning, such as pumps, valves, filter vessels, heat exchanger, etc.
In the pipeline, there is limited use of pipe fittings. Mostly, you will witness bends with long radius and very few other types of fittings accompanied by a pumping station and valve station.In the case of piping, you will find a wide range of pipe fittings that is supposedly for the direction, size, branching, blinding to form a well-defined piping system.

Now that you know the significant differences between the pipeline and piping system, you need to learn other aspects of piping engineering in detail. If you are looking for in-depth knowledge about oil and gas training courses online, check out our website for more information.
