Schedule 20 Pipe: An Introduction to the Basics

Pipes are an essential component of various industries for transporting gases, liquids, and solids from one place to another. Schedule 20 pipes are popularly used in many applications among the broad range of pipes. In this blog post, we will discuss what schedule 20 pipe is, its benefits, how it is made, and its various uses.

What is a Schedule 20 Pipe?

Schedule 20 Pipe is a thin-walled, lightweight, and economical type of pipe with a nominal pipe size of 20. The nominal pipe size is the size used to describe the diameter of the pipe, although its measurements can vary slightly. In most cases, the outer diameter of Schedule 20 is the same as Schedule 40, but the wall thickness is smaller in Schedule 20 pipes.

Benefits of the Schedule 20 Pipe

The Schedule 20 pipe has several benefits that make it suitable for various applications. First, it is made of strong, durable materials that withstand high pressure and temperature. It is also easy to install, making it perfect for commercial and residential buildings. Additionally, it is lightweight and cost-effective to save money on transportation and installation costs.

How is Schedule 20 Pipe Made?

Schedule 20 pipes use the same manufacturing process as others, such as Schedule 40. The first step is to cut the raw materials, often steel or plastic, into the desired length. The next step is to form the pipe into the correct diameter and thickness, followed by annealing. Annealing involves heating the pipe too high and cooling it slowly to relieve any internal stress, making it stronger and more durable. The last step is to add any necessary coatings or treatments, such as epoxy, to make the pipe resistant to corrosion.

Uses of Schedule 20 Pipe

The Schedule 20 pipe is used in several applications, including plumbing, HVAC, and fire sprinkler systems. It can also be used for drainage, irrigation, and sewage systems. Because it is lightweight and ideal for use in tight spaces or areas with low load-bearing capacity. It is also used in industrial applications, such as chemical and petrochemical plants, where it can transport hot gases, liquids, and chemicals.


Schedule 20 pipes are an economical and useful type of versatile pipe that can be used in a wide range of applications. It is lightweight, durable and can withstand high pressure and temperature, making it suitable for various industries. In this blog post, we have discussed the basics of Schedule 20 pipe, its benefits, how it is made, and its uses. Next time you need a pipe, consider schedule 20 pipe and enjoy its many benefits.
