As the industrial requirements handling higher pressure fluids, pipes were manufactured with thicker walls, which has become known as an extra strong (XS) or extra heavy (XH).

Definition and Details of Steel Pipe Schedule

Steel Pipe Schedule

    at the IPS time only three walltickness were in use. the American Standards Association
surveyed industry and created a system that designated wall thicknesses based on smaller
steps between sizes. Steel Pipe Schedule Chart PDF Download  .The designation known
as nominal pipe size replaced iron pipe size, and the term schedule (SCH) was invented to
specify the nominal wall thickness of pipe. By adding schedule numbers to the IPS standards,
today there is a range of 16 schedules, namely:
SCH 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, and STD, XS, XXS.

 

PIPE SCHEDULE 

The pipe schedule sets the pipe wall thi ckness. Obviously increasing the wall thickness of the pipe
increases the mechanical strength of the pipe, allowing it to handle higher design pressures.

The following pipe schedules are available (in order of increasing wall thickness): 5S, 10S, 10, 20, 30, 40S, STD, 40, XS (Extra Strong), 60, 80, 100, 120, 140, XXS (Double Extra Strong) and 160. So for pipe of 12 inch NB (DN 300 mm) with a pipe schedule 5S, has a wall thickness of 0.156 inches (4 mm) . As the schedule is increased, so does the wall th ickness. At a pipe schedule of 160, a 12 inch NB pipe has a wall thickness of 1.312 inches (33.3 mm).

It should be noted that not all pipe schedules are available for all pipe sizes.
