Example- 10S Standard Pipe Schedule as per ASME B36.10 and B36.19 Under ASME B36.19 Schedule no with “S” suffix is introduced for SS pipe. To reduces the cost of material ASME has introduced different schedule numbers for stainless steel pipe and fittings. Due to corrosion resistance properties of stainless steel, advancement of high alloy stainless steel and fusion welding less thickness pipe can be work satisfactorily without fear of early failure. Pipe Schedule for Stainless Steel PipeĬost of stainless steel pipe is much higher than carbon steel pipe. That means with an increase in service pressure schedule number will increase which is a pipe wall thickness designator. Look at the above formula of schedule number, allowable stress for material at a given temperature is fixed. Schedule 80 pipe is thicker than schedule 40 pipe. Now, can you tell me which is thicker schedule 40 or 80 pipe? In simple word you can say that for a given material, schedule 40 pipe can withstand a certain amount of pressure.

Schedule 40 is nothing but a pipe thickness designator. You can see the pipe schedule calculation formula as below To simplify the ordering of the pipe ASME committee has developed Schedule Number which is based on modified Barlow’s wall thickness formula.ĭefinition of Schedule Number: The schedule number indicates approximate value of the expression 1000 x P/S where P is the service pressure and S is the allowable stress, both expressed in pounds per square inch. The pipe schedule is the way pipe wall thickness is mentioned. Form 6” to 42”, it increases by 2” step and after that in 4”. There is no change in other dimensions when you use DN.įrom this table, you can see that initially pipe size increase by ¼ than ½ and then by 1”. Check the below table for easy understanding. You can get any NPS to DN by multiplying it with 25. Here, you have to note that DN shows pipe sizes differently than NPS.Ģ” pipe is simply mentioned as DN 50. What is DN (Diameter Nominal) Pipe Sizes?ĭN or Diameter Nominal is an International designation (SI or Matric Designator) and also a European equivalent of NPS to show pipe sizes. So when someone says 25nb pipe or 50nb pipe basically they are talking about DN. I have also seen that when pipe dimensions are shown in mm (DN) people refer pipe sizes in NB. NB is also an American way to refer pipe dimensions. As such, there is no difference between NB and NPS. NPS is frequently referred as an NB (Nominal Bore).
