Alloy & Carbon Steel Schedule 40 Pipe Size Chart as per ASME B36.10

Steel pipes are manufactured in various grades and categorized into different schedules, each with specific standards for measuring pipe thickness. As the schedule number increases, the thickness of the pipe also increases. Schedule 40 is a versatile pipe known for its proven performance. These pipes can undergo two different zinc coating methods: in-line Galvanization and hot-dip galvanization. Hot-dip galvanization allows the zinc to bond with the pipe, providing enhanced protection. Schedule 40 pipe is known for its regular pressure ratings and high strength grade. The outer diameter and wall thickness of a pipe can be determined using NPS (Nominal Pipe Size) and scheduled pipes. For example, NPS 14 schedule 40 pipe will have an outside diameter of 14 cm and a wall thickness of 0.437 inches. The schedule number plays a crucial role in determining the inside and outside diameter of the pipe.

The schedule 40 pipe dimensions are provided in the table above. The weight of schedule 40 steel pipes varies depending on the pipe size. On average, the weight per foot of sch 40 is approximately 1.68 lbs. Each type of pipe has its own advantages, and the same applies to sch 40 pipe. Due to their thinner walls, sch40 are considered ideal for applications with low water pressure. However, it is crucial to ensure that the dimensions of schedule 40 pipe size chart meet the requirements of your specific application. Remember that the strength of the pipe is only as strong as its weakest point, and any variation in pressure can immediately impact its performance.

The schedule 40 pipe thickness can be determined from the provided table. Initially, standard pipe schedule were divided into three sections: standard weight (STD), double extra strong (XXS), and extra strong (XS), based on the pipe size. Although these classifications were expected to be phased out by suppliers of schedule 40 steel pipes, they are still widely used. DN (Nominal Diameter) is a dimensionless specification indirectly related to the pipe’s diameter according to ISO 6708. It does not directly correspond to the size or schedule 40 pipe thickness in mm. Originally, NPS values had the same inside diameter, but as the ss 304 schedule 40 pipe thickness evolved, the inside diameter changed, and NPS became indirectly related to both the inside and outside diameter. We have been manufacturing schedule 40 pipe dimensions in mm for generations and customizing them according to specific application requirements. The schedule 40 pipe weight varies based on the amount of metal used and the thickness of the pipe’s wall.

What is the meaning of Schedule 40 pipe?

Schedule 40 on a pipe means that it can hold 40 kg of pressure. It’s shown by a standard thickness of 4 mm. The most common pipe schedule is Schedule 40 Steel Pipe. It can be galvanised, but it doesn’t have to be, and is usually
used for water and gas lines. It can also be found in places that need to be decorated or held up. It makes a great pipe because it can be used in many ways and works well. ANS!

Based on the NPS and schedule of a pipe, the pipe outside diameter (OD) and wall thickness can be obtained from reference tables such as those below, which are based on ASME standards B36.10M and B36.19M. For example, NPS 14 Sch 40 has an OD of 14 inches (360 mm) and a wall thickness of 0.437 inches (11.1 mm).

WHAT DO PIPE SCHEDULES MEAN?

What are Pipe Schedules?

The schedule number on pipe products relates to the thickness of the wall on the pipe: as the number increases, the thicker the wall thickness becomes. Also, while the schedule number can be the same on different sized pipes, the actual wall thickness will be different. Here are a few examples:

Pipe size 1.000” Schedule 40 – The actual wall thickness is 0.133”

Pipe size 2.000” Schedule 40 – The actual wall thickness is 0.145”

Pipe size 1.000” Schedule 80 – The actual wall thickness is 0.179”

Pipe size 2.000” Schedule 80 – The actual wall thickness is 0.218”

What we can see here is that the schedule number increases the wall size, and that the wall thickness changes based on the nominal pipe size (NPS).

The best way to see the relationship between pipe size, schedules and wall thicknesses is simply to refer to a conversion chart (below):

There are several schedule numbers used on pipe, such as schedules:  5, 5S, 10, 20, 30, 40, 60, 80, 100, 120, 140, 160, STD, XS and XXS. The most common ones used are schedules 40 and 80

Chemical Composition of Schedule 40 Steel Pipe

Schedule 40 steel pipe is a type of steel pipe with a standard thickness and is commonly used in a variety of applications.

  1.5%. Carbon gives steel its strength and hardness, and also influences its ductility, toughness, and weldability.
• Manganese (Mn): Manganese is often added to steel to improve its strength, toughness, and hardenability. It is typically
  present in amounts ranging from 0.3% to 1.5%.
• Phosphorus (P): Phosphorus is typically present in small amounts in steel, ranging from 0.04% to 0.12%. It can have
  both positive and negative effects on steel, depending on the specific application.
• Sulfur (S): Sulfur is another element that is typically present in small amounts in steel, ranging from 0.05% to 0.30%. It
  can have both positive and negative effects on steel, depending on the specific application.

  amounts ranging from 0.15% to 0.40%.
• Copper (Cu): Copper is sometimes added to steel to improve its corrosion resistance. It is typically present in small
  amounts, ranging from 0.20% to 0.40%.
• Chromium (Cr): Chromium is often added to steel to improve its corrosion resistance, hardness, and strength. It is
  typically present in amounts ranging from 0.08% to 0.40%.
• Nickel (Ni): Nickel is also added to steel to improve its corrosion resistance, strength, and toughness. It is typically
  present in amounts ranging from 0.25% to 0.45%.

The specific chemical composition of Schedule 40 steel pipe can vary depending on the grade and type of steel used, as
well as any additional alloying elements that may be added. It is important to consult the manufacturer’s specifications
for the specific chemical composition of any given Schedule 40 steel pipe.

What does Nominal Pipe Size or NPS mean?

The NPS size represents the approximate inside diameter (not outside) of the pipe; if the schedule number on a set size is changed, it does effect the inside diameter (ID) but not the outside diameter (OD). In 1927 the American Standard Association replaced the previously used Iron Pipe Sizing (IPS) with Nominal Pipe Sizing (NPS).  This North American standard is used on pipes for high or low pressures and temperatures.   Example:

NPS                    OD                      Schedule #      Wall Thickness       ID

1.000”               1.315”               SCH 40              0.133”                 1.049” (approx.)

1.000”               1.315”               SCH 80              0.179”                 0.957” (approx.)

All pipes are specified using the NPS and schedule numbers. It is the schedule number that determines the approximate inside diameter.

Based on ASTM A53 – Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless.

ASTM A53 pipe – also referred to as ASME SA53 pipe – is intended for mechanical and pressure applications. Can be used in steam, water, gas and air lines. Suitable for welding and forming like coiling, bending and flanging.
