Reset Specs.Standardization of wrought steel Pipe schedule and pipe sizes begin with mass production era. 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.
This will result in the concept of the schedule number that combines wall thickness and diameter of the pipe. Nominal pipe size NPS is the number that defines the size of the pipe.
It also depends on the size of the pipe. To understand this concept, you have to learn the way pipes are manufactured. 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.
Pipe Chart, Pipe Dimensions, Pipe Wall Thickness
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. 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 main content Skip to primary sidebar.By: John Brady October Then choose the schedule from the top row. Find where your pipe size and schedule intersect. You will see that each box has two numbers describing your pipe selection. The top number, in blueis the wall thickness.
The black number below is the weight in pounds per foot of pipe. Nominal Pipe Size NPS Nominal Pipe Sizelisted in the first column of our Pipe Chartidentifies the nominal diameter of the pipe which lies between the inside and outside diameters.
Pipe Weight The weights given on our pipe chart are based on carbon steel pipe but can vary due to many factors including manufacturing tolerances and other allowable factors such as alloy.

First, what is this pipe chart showing? It describes the physical dimensions and weights of standardized pipe. All pipe manufacturers produce pipe according to these standardized physical characteristics.
When viewing the pipe chart, each NPS has two corresponding rows. The first row shows the wall thickness in inchesand the second shows the weight in lbs. Pipe Diameters are not actually round numbers. Accordingly, the pipe chart's second column displays the actual outside diameter OD of pipe relative to NPS. The Outside Diameter OD does not change. As the pipe schedule increases or decreases, the outside diameter remains constant, and the inside diameter changes accordingly.
This is simply a difference in terminology, where one group refers to "Extra Extra Heavy" and another refers to "Extra Extra Strong". The physical dimensions of each are the same, and the terms may be used interchangeably.
XH and STD are complicated. After this, the two diverge, and either "True 40" or STD must be specified, as they each indicate distinct wall thicknesses.
True 80 and XH take hold thereafter.
The same is not to be confused for schedule and XXH, as though it is tempting to assume they have a similar relationship, XXH and are two separate wall thicknesses for every NPS.
The weight can vary. The weights given are theoretical, but they can vary slightly due to acceptable manufacturing tolerances in the diameter and wall thickness of the pipe. However, different materials will have different pipe weights. To approximate pipe weights for other materials, simply multiply the weight in the chart above by the factor in the table below.

Download Pipe Specification Chart.This pipe thickness calculator calculates required pipe thickness for a process pipe based on ASME B This calculator calculates required thickness of a pipe under internal pressure based on criteria specified in section Though the formula is quite simple, finding correct values of individual factors can be tricky sometimes. This process pipe thickness calculator uses following formula for calculation of wall thickness.
In this calculator, outside diameter is taken from American Pipe Standards for the selected nominal pipe diameter :. These are allowable stress values for different materials at different temperatures. I have included commonly used pipe materials in this calculator. If you want more ASTM materials to be included, please mention in comments section below.
