What is Carbon Steel Pipe Schedule Chart?
A Carbon Steel Pipe Schedule Chart helps to understand the thickness and internal size of pipes without specific measurements. The chart uses schedules, ranging from sch 5 to SCH 160 and XXS, to show different wall thicknesses. Higher schedule numbers, like SCH 120 pipe, indicate thicker walls that can support more weight and pressure, making them suitable for tough conditions. Even if pipes have the same diameter, their wall thickness can vary based on the schedule, such as the SCH 140 pipe compared to schedule 40. Carbon steel pipes are marked with an "CS" for easy grade identification. Generally, the higher the schedule, the heavier and stronger the pipe.
Common Pipe Schedules
Some common pipe schedules include:
Schedule 40: This type of pipe schedule is probably the most popular because it applies to water and gas lines.
Schedule 80: This schedule is used when pressure levels are higher, such as in pipeline systems for transmitting oil and gas.

Carbon Steel Pipe Schedule 80 Based On ASME B36.10
The SCH 80 Carbon Steel Pipe is a type of pipe known for its strength and is part of the Carbon Steel Pipe Schedule 80 category. It's defined by its "sch 80 pipe thickness in mm," which means it has a thicker wall than standard pipes. This thickness makes it capable of handling high pressures and tough conditions, making it a preferred choice for industrial applications. You should look at the SCH 80 Pipe chart for exact sizes and capacities.

Carbon Steel Pipe Schedule 40 Chart
SCH 40 Carbon Steel Pipe is designed for durability and efficiency. The "schedule 40 pipe wall thickness" refers to its specific thickness, making it sturdy yet not overly heavy. Measured in "sch 40 pipe thickness in mm," it provides a reliable balance between strength and flow capacity, suitable for various uses.
Carbon Steel Schedule 60 Pipe Chart
Schedule 60 Carbon Steel Pipe is a strong and durable pipe used in various applications. It is known for its thickness, which is measured in millimetres. Specifically, the "schedule 60 pipe thickness in mm" indicates how thick the walls of the pipe are, making it capable of handling high pressures and tough conditions.

How is a Pipe Schedule Calculated?
The pipe schedule calculation is simply the design pressure and allowable stress multiplied by 1000, making a value that dictates the pipe's wall thickness.
The pipe schedule number (SCH) is calculated as:
SCH=1000*(P/S)
For instance, a pipe has a design pressure of 1000 psi and an allowable stress of 20,000 psi; it will be of schedule number 50 (1000 multiplied by reverse reciprocal parentheses (1000 divided by 20,000)).
Importance of Pipe Schedules
Pipe Schedules help ensure the safety and effectiveness of piping systems. They also enable:
