Example- 10S. NB is also an American way to refer pipe dimensions. You can easily convert inch dimension to mm by multiplying it with Nominal Pipe Size. Standardization of wrought steel Pipe schedule and pipe sizes begin with mass production era. You are here:
So, any increase in wall thickness decrease the inside diameter ID of the pipe and this ID of the pipe is approximately equal to the Nominal Size. With below example, you have more clarity of the concept.
You can easily convert inch dimension to mm by multiplying it with NB is also an American way to refer pipe dimensions. I have also seen that when pipe dimensions are shown in mm DN people refer pipe sizes in NB.
So when someone says 25nb pipe or 50nb pipe basically they are talking about DN. Check the below table for easy understanding. There is no change in other dimensions when you use DN. Pipe schedule is the way pipe wall thickness are mentioned.
Definition of Schedule Number: Schedule 40 is nothing but a pipe thickness designator. In simple word you can say that for given material, schedule 40 pipe 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 given temperature is fixed.
That means with an increase in service pressure schedule number will increase which is pipe wall thickness designator. 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 be work satisfactorily without fear of early failure. To reduces the cost of material ASME has introduced different schedule number for stainless steel pipe and fittings.
Example- 10S. However, each product has its own requirements and when given in that specification that will govern over the A Skip to content Skip to primary sidebar.
You are here: Height With modernizing of various industries and use of pipe in different pressure and temperature condition these three sizes are not sufficient to meet the requirement.
