Schedule 80 Vs 40
Introduction
As a plumber, I have had my fair share of confusion when it comes to choosing the right material for pipes. One of the most common questions I get asked is whether to go for schedule 80 or schedule 40 pipes. In this article, we will explore the differences between the two and help you make an informed decision.
What is Schedule 80?
Schedule 80 is a type of pipe with thicker walls compared to schedule 40 pipes. This makes it more durable and ideal for applications that require high pressure and temperature. Schedule 80 pipes are commonly used in industrial settings such as chemical plants, refineries, and power plants.
What is Schedule 40?
Schedule 40 pipes, on the other hand, have thinner walls compared to schedule 80 pipes. They are less expensive and are commonly used in residential and commercial settings such as homes, schools, and hospitals. Schedule 40 pipes are also used in irrigation systems and swimming pools.
Key Differences
The main difference between schedule 80 and schedule 40 pipes is their thickness. Schedule 80 pipes have thicker walls and can withstand higher pressure and temperature compared to schedule 40 pipes. Another difference is the cost, with schedule 80 pipes being more expensive due to the higher material and manufacturing costs.
Schedule 80 Vs 40: Which One to Use?
When deciding which one to use, it is important to consider the application. If you are dealing with high pressure and temperature, then schedule 80 pipes are the best option. They are also ideal for industrial settings where durability is a key factor. However, if you are dealing with lower pressure and temperature, then schedule 40 pipes will suffice. They are also more affordable and can be used in residential and commercial settings.
