# Schedule 40 Pipe (SCH40) weight list

What’s the meaning of Schedule 40 pipe?

Mild Steel(MS) Schedule 40 Pipe (SCH40) weight ,dimensions, wall thickness chart and Steel Metal Weight Calculation formula listed below.

Grounded on the NPS and schedule of a pipe, the pipe outside periphery( OD) and wall consistence can be attained from reference tables similar as those below, which are grounded on ASME norms B36.10 M and B36.19M. For illustration, NPS 14 Sch 40 has an OD of 14 elevation( 360 mm) and a wall consistence of0.437 elevation(11.1 mm).
NPS OD Schedule# Wall Thickness ID.1.000 ”1.315 ” SCH 400.133 ”1.049 ”( approx.)1.000 ”1.315 ” SCH 800.179 ”0.957 ”( approx.) All pipes are specified using the NPS and schedule figures. It’s the schedule number that determines the approximate inside periphery.

What Do pipe Schedules Means?
What are Pipe Schedules?
The schedule number on pipe products relates to the consistence of the wall on the pipe as the number increases, the thicker the wall consistence becomes. Also, while the schedule number can be the same on different sized pipes, the factual wall consistence will be different. Then are a many exemplifications

Pipe size1.000 ” Schedule 40 – The factual wall consistence is0.133 ”

Pipe size2.000 ” Schedule 40 – The factual wall consistence is0.145 ”

Pipe size1.000 ” Schedule 80 – The factual wall consistence is0.179 ”

Pipe size2.000 ” Schedule 80 – The factual wall consistence is0.218 ”

What we can see then’s that the schedule number increases the wall size, and that the wall consistence changes grounded on the nominal pipe size( NPS).
