What does the SCH represent for steel pipe dimensions
When describing the parameter for the steel tube, we usually do it using the tube ID. It is a method that expresses the wall thickness of the tube in numbers. However, the tube ID (SCH) is not equal to the wall thickness, but represents that tube within a series of a certain thickness. Different IDs mean different wall thicknesses for steel pipes with the same diameter. The most frequent indicators of the pipeline are SCH 5, 5S, 10, 10S, 20, 20S, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160. The higher the number in the table, higher is its resistance to pressure.
What does Steel Pipe Schedule 40 and Schedule 80 mean
If you are someone new to the pipe industry, you may be wondering: Why do you always see ID 40 or 80 when talking about steel pipes? What type of material is used in these tubes?
As you can read in the previous sections, ID 40 or ID 80 represents the wall thickness of the tube, but why are these two the most preferred by consumers?
Here is the reason:
Schedule Tubes 40 and 80 are the most common sizes used by different industries. This is due to the general pressure that these tubes withstand, and therefore they are always bought in large quantities.
The standard material for tubes with this type of thickness has no limitations. You could order a stainless steel tube with ID 40, such as ASTM A312 Grade 316L, or a carbon steel pipe ID 40, such as API 5L, ASTM A53, ASTM A106B, A 179, A252, A333, etc.
