Here, you have to note that DN shows pipe sizes differently than NPS.Ģ” pipe is simply mentioned as DN 50. You can get any NPS to DN by multiplying it by 25. Check the below table for easy understanding. There is no change in other dimensions when you use DN.įrom this table, you can see that initially pipe size increases by ¼ than ½ and then by 1”. From 6” to 42”, it increases by 2” step and after that in 4”. The pipe schedule is the way pipe wall thickness is mentioned. You can see the pipe schedule calculation formula 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 an 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. Schedule 40 is nothing but a pipe thickness designator. Now, can you tell me which is thicker schedule 40 or 80 pipes? In simple words, you can say that for a given material, schedule 40 pipes can withstand a certain amount of pressure. Schedule 80 pipe is thicker than schedule 40 pipe. Look at the above formula of schedule number, allowable stress for material at a given temperature is fixed. Piping Quiz Level 1- Pipes Pipe Schedule for Stainless Steel Pipe That means with an increase in service pressure schedule number will increase which is a pipe wall thickness designator. The cost of stainless steel pipe is much higher than carbon steel pipe. Due to corrosion resistance properties of stainless steel, advancement of high alloy stainless steel, and fusion welding, less thickness pipe can work satisfactorily without fear of early failure. To reduces the cost of material ASME has introduced different schedule numbers for stainless steel pipe and fittings. Refer to the table given below that summarized the available schedule numbers for carbon steel and stainless steel pipe based on ASME B36.10 and B36.19.CN102139293B - Metallic conical pipe coiling machine Example- 10S Standard Pipe Schedule as per ASME B36.10 and B36.19 with the “S” suffix is introduced for SS pipe.
