How to determine pipe strength?
The term ‘schedule’ when referring to the ANSI pipe schedule chart, is a way of determining pipe strength by comparing the inside thickness of the pipe and the outside diameter of the pipe. When comparing pipe from different schedules, the outside diameter will stay the same, but the stronger the pipe, the thicker the inside wall of the pipe material will need to be. As you reach a higher number on the pipe schedule chart, pipe with the same outer diameter will need to have a thicker inner diameter in order to provide more strength. Therefore, you can refer to the pipe schedule chart to find the diameter of inside thickness you need for a given application.

Pipes which do not correspond to the forgoing weight classes are designated by the term "Pipe ", outside diameter (in.), and wall thickness (in.)
What is nominal pipe size?
Download Data Sheet (.PDF) Nominal Pipe Size (NPS) is a North American set of standards used to designate pipe diameter and thickness. Pipe size is specified with two non-dimensional numbers: a nominal pipe size (NPS) for inside diameter based on inches, and a schedule (Sched. or Sch.) for wall thickness.
What is ANSI B36.10/19?
ANSI B36. 10/19 is the most recognized sizing specification for steel pipe in the US. Extra Heavy (XH) is used to describe the minimum wall thicknesses for pipe and some pipe fittings. For sizes up to 8", XH is the same wall thickness as schedule 80.
What is nominal pipe size?
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. Nominal pipe size refers to only the outside diameter (OD) of a pipe making it somewhat vague. For example, when we say pipe size is 2 NPS, it refers to all the pipes having 2.375-inch (or 60.3 mm) as outside diameter irrespective of wall thickness and thus the inside diameter. Specific pipe is identified by pipe diameter and another non-dimensional number for wall thickness referred to as the Schedule (SCH). Pipe schedule sets the pipe wall thickness. Increasing the wall thickness of the pipe increases the mechanical strength of the pipe, allowing it to handle higher design pressures.
How many inches is a NPS 12 pipe?
For NPS ⅛ to 12 – The NPS and OD values are different. For example, the OD of an NPS 12 pipe is actually 12.75 inches (324 mm). To find the actual OD for each NPS value, refer to the reference tables which are based on ASME standards B36.10M and B36.19M.
What is nominal bore?
Nominal Bore (NB) is European Designation equivalent to NPS. For NPS 5 and larger, the Nominal Diameter (DN) is equal to the NPS multiplied by 25.

What is pipe schedule?
As describing the steel pipe parameter, we usually use the pipe schedule, It is a method that represent pipe wall thickness with number. Pipe schedule ( sch. ) is not a wall thickness, but a wall thickness series. Different pipe schedule means different wall thickness for the steel pipe in the same diameter. The most frequently indications of schedule are SCH 5, 5S, 10, 10S, 20, 20S, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160. The larger the table number, the thicker the surface pipe wall, the higher the pressure resistance.
What is Steel Pipe Dimensions Schedule?
Steel pipe schedule is a indicating method represented by ASME B 36.10, and also used in many other standards, marked with “Sch”. Sch is the abbreviation of schedule, generally appearing in the American steel pipe standard, which is a prefix of a series number. For example, Sch 80, 80 is a pipe number from chart/table ASME B 36.10.
What is a WGT class?
WGT class (weight class) is an indication of the pipe wall thickness in early, but still used. It has only three grades, namely STD ( standard ), XS ( extra strong ), and XXS ( double extra strong ).#N#For the earlier production pipe, each caliber has only one specification, called standard tube (STD). In order to deal with high pressure fluid, the thickening pipe (XS) appeared. XXS ( double extra strong ) pipe appeared to handle the higher pressure fluid. People began to require the use of more economical thin-walled pipe until the emergence of new materials processing technology, then gradually appeared the above pipe number. The corresponding relation between pipe schedule and weight class, refer to ASME B36.10 and ASME B36.19 specification.
What is DN pipe?
DN (nominal diameter) is the general diameter of various pipe and pipeline accessories. The same nominal diameter of the pipe and pipe fittings can be interconnected, it has interchangeability. Although the value is close or equal to inside diameter of pipe, It is not the actual sense of the pipe diameter.
What is nominal diameter?
DN (nominal diameter) is the general diameter of various pipe and pipeline accessories. The same nominal diameter of the pipe and pipe fittings can be interconnected, it has interchangeability. Although the value is close or equal to inside diameter of pipe, It is not the actual sense of the pipe diameter. The nominal size is represented by a digital symbol followed by the letter “DN”, and mark the unit in millimeters after the symbol. For example, DN50, a pipe with a nominal diameter of 50 mm.
What is nominal pipe size?
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. Pipe size is specified with two non-dimensional numbers: a nominal pipe size (NPS) based on inches, and a schedule (Sched. or Sch.).
Why are Schedule 40 and 80 steel pipes used?
Here is the reason: Schedule 40 and 80 steel pipe as the common sizes that required in different industries, because of the generally pressure these pipes bear, they are always been asked for a large quantity.
What is Pipe Schedule?
The pipe schedule is the way pipe wall thickness is mentioned. To simplify the ordering of the pipe ASME committee has developed Schedule Number which is based on modified Barlow’s wall thickness formula.
What is Nominal Pipe Size?
Nominal pipe size (NPS) is the number that defines the size of the pipe. For example, when you say 6” pipe, the 6” is the nominal size of that pipe. However, for the pipe sizes, NPS 14 and above Outside Diameter is the same as NPS. To understand this concept, you have to learn the way pipes are manufactured.
What is Pipe NB (Nominal Bore)?
NPS is frequently referred as an NB (Nominal Bore). As such, there is no difference between N B and NPS. 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.
What is NPS in pipe?
Nominal pipe size (NPS) is the number that defines the size of the pipe. For example, when you say 6” pipe, the 6” is the nominal size of that pipe. However, for the pipe sizes, NPS 14 and above Outside Diameter is the same as NPS. To understand this concept, you have to learn the way pipes are manufactured. Manufacturing of NPS ⅛ (DN 6) ...

Note-4: For thin-wall pipe, the ovality in any one cross-section shall not exceed 1.5 % of the specified outside diameter.
Is NPS 2 pipe ID the same as NPS 14?
From the above table, you can see that for NPS 2, Pipe ID is near to pipe NPS and for NPS 14 pipe OD is same as NPS.
What is pipe schedule?
The pipe Schedule describes the pipe wall thickness. With an increase in pipe schedule number pipe thickness increases. The main function of the pipes is to carry fluid (liquid, gas, fluidized solids, slurry, mixed-phase products, etc) under pressure (internal, external, or both), therefore to sustain the fluid pressure the pipe has to be strong enough to perform its intended duty without failure. Obviously, for pipes containing pressurized fluids the wall thickness, and by implication the pipe’s strength, is the most important parameter. Wall thickness of Pipe is expressed by “schedules or Schedule numbers“, referred to as pipe schedules or Piping Schedules.
How thick is Schedule 40 pipe?
It may be same or vary with respect to pipe sizes. For example, 6 inch schedule 40 pipe have 7.11 mm thickness, while 8 inch Schedule 40 pipe have 8.18 mm thickness means thickness is increasing even though both the schedule 40.
How to Calculate a Pipe Schedule?
Schedule Numbers for pipe size/wall thickness combinations are calculated (approximated) to get a uniform relationship equal to 1000 times the P/S (P=Design Pressure and S=Allowable Stress) expression contained in the modified Barlow formula for pipe wall thickness. The pipe schedule is abbreviated as SCH. So,
What is the difference between XXS and SCH?
The double Extra Strong (XXS) wall is thicker than SCH 160 from NPS 1/8 to NPS 6, and SCH 160 is thicker than the XXS wall for NPS 8 and larger.
What is the size of a pipe?
The size of all pipe is identified by the nominal pipe size. The manufacture of pipe NPS 1⁄8 (DN 6) to NPS 12 (DN 300), inclusive, is based on a standardized outside diameter (OD). This OD was originally selected so that pipe with a standard OD and having a wall thickness that was typical of the period would have an inside diameter (ID) approximately equal to the nominal size. Although there is no such relation between the existing standard thickness — OD and nominal size — these nominal sizes and standard ODs continue in use as ‘‘standard.’’
What is a pipe size chart?
A pipe size chart or pipe schedule chart is a tabular representation of pipe NPS and their thicknesses with respect to various schedule numbers. The wall thickness associated with a particular schedule depends on the pipe size. Dimensions (OD, ID, Thickness, and Schedule Number) and Weights of CS and SS pipes are given in ASME standards mentioned above. The tables in the respective codes are dimensionally complete for all sizes and wall thicknesses within its scope, but some of the larger, heavier wall sections are beyond the capability of seamless mill production and must be obtained from forged and bored billets or other sources.
What is the ASME standard for pipe thickness?
For a given pipe size and schedule the thickness of the pipe is fixed and defined in the applicable ASME standard (B 36.10M/B 36.19M). Even though Pipe thickness can also be specified in mm or inches to the value corresponding to that specified in the ASME standard, The Schedule Numbers are strictly used as a convenient designation system while ordering piping items.
