Types of Line Pipe:

Pipelines can be categorized into different types. The following pipelines are classified according to the type of fluids and items transported. It is important to read the following for an understanding of each type.


- Water and Drain Line Pipe

This type is used to carry H2O from one location to another. They are typically made of metal or plastic, and they are usually buried underground. These are typically coated with a material that helps to prevent rusting. In addition, such pipelines may be equipped with fittings that help to connect to other types of pipes or fixtures. They are an essential part of any plumbing system, and they are typically used in residential, commercial, and industrial applications.


- Oil Line Pipe

This type is defined as having the advantage to be used to carry petroleum products such as crude oil and natural gas. They are typically made of steel or iron, which can be susceptible to rusting. To protect the pipes from rusting, a coating is often applied. This coating can be made of various materials, including plastic and resin. Once the petroleum products have been transported through the pipelines, they can then be refined into useful products such as gasoline and diesel fuel.


- Gas Line Pipe

The specification of types of pipelines is that it is used to carry and transport natural gas. It is generally made of steel, which is a strong and durable material. However, over time, steel can start to corrode and weaken. To protect the pipelines from rust, it is often coated with a layer of plastic or other material. Such pipelines are typically buried underground, but they can also be installed above ground. The pipelines must be properly maintained to ensure that it does not leak or burst, which could pose a serious safety hazard.
