Steel pipes come in various grades, each with different schedules dictating their thickness. Schedule 40 Steel Pipe, a commonly used type, offers versatility and proven performance. These pipes can be zinc-coated through in-line galvanization or hot-dip galvanization, enhancing their durability. The “sch 40” designation signifies its ability to withstand 40 kg pressure, marked by a standard 4 mm thickness. ANSI B36.10 standards include a range of wall thicknesses from Sch10 to Sch160, providing options for diverse applications in construction and industrial settings.

What is Schedule 40 Pipe?

When you see “Sch40” on a pipe, it means the pipe can handle 40 kg of pressure, and has a standard thickness of 4 millimeters.

Schedule 40 Steel Pipe is a type of pipe that can be used for different purposes, such as carrying air, oil, water, and natural gas. These pipes are made from different grades of steel and are resistant to corrosion from chloride ions, reducing the risk of stress cracks. The material also has lower carbon content, making it easier to weld and less prone to rusting in specific areas. Pipes with a diameter of less than 10 inches are suitable, with smaller pipelines using the 1-inch Schedule 40 Stainless Steel Pipe.

Sch 40 pipes are versatile and efficient. The ANSI B36.10 standard provides various wall thickness options, including Sch10, Sch20, Sch30, Sch40, Sch60, Sch80, Sch100, Sch120, Sch140, and Sch160, allowing for flexibility in different applications.

Schedule 40 Stainless Steel Pipe is versatile and used for various piping needs like air, oil, water, and natural gas. It’s made from different steel grades, resistant to chloride ions and stress cracks. Being low in carbon makes it easier to weld and less prone to rust.

These pipes are best for smaller diameters, like the 1-inch Schedule 40 Stainless Steel Pipe. Their weight varies with size, generally around 1.68 lbs per foot. Due to their thinner walls, they suit low water pressure applications. However, it’s crucial to match pipe size with application needs for optimal strength and performance.

It makes a great pipe as it can be used in various industrial applications. ANSI B36.10 wall thickness: Sch10, Sch20, Sch30, Sch40, Sch60, Sch 80 pipe, Sch100, Sch120, Sch140, Sch160 ten levels.

Schedule 40 Steel Pipe Weight

The schedule 40 steel pipe weight depends on their size. Generally, The weight of schedule 40 pipe per foot is 1.68 lbs. Sch 40 pipes are good for applications with low water pressure because they have thinner walls. It’s important to choose the right size of schedule 40 pipes for your needs, as their strength depends on their size.

You can use a table to find out how thick the schedule 40 pipes are. In the past, these pipes were categorized into standard weight (STD), double extra strong (XXS), and extra strong (XS) based on their size.  Although suppliers were supposed to stop using these classifications, they are still in use.

Manufacturers and suppliers offer Schedule 40 Pipes in various materials like Stainless Steel, ASTM A106 Grade B, A53 Grb, A333 Grade 6, Aluminum, API 5L Gr. B Carbon Steel, and Gi material.

What does NPS (Nominal Pipe Size) stand for?

The NPS size represents the pipe’s approximate inside diameter; if the schedule number on a set size is changed, the inside diameter (ID) but not the outside diameter (OD) is affected (OD). Nominal Pipe Sizing was developed by the American Standard Association to replace the previously employed Iron Pipe Sizing. For high or low pressures and temperature pipes, this North American standard is employed.

Chemical Composition of Schedule 40 Steel Pipe

Schedule 40 pipe is categorized based on its nominal wall thickness, rather than the grade of the material. This means that the chemical composition of a Schedule 40 pipe can vary. Typically, Schedule 40 pipes are made from low-carbon steel, most commonly A53 grade steel.

The sch 40 pipe thickness is designed to handle a variety of pressures, making it suitable for numerous applications. For instance, seamless weld type S A53 steel pipes may have varying chemical compositions based on the type of weld, but they generally follow specific guidelines for elements such as carbon, manganese, and others.

To determine the specific sch 40 pipe dimensions you need, it’s essential to refer to the relevant charts and standards. These will provide detailed information on the thickness and diameter of the pipes, ensuring you select the right dimensions for your project’s requirements. This is crucial for maintaining the integrity and performance of the piping system.

  • Carbon – 0.25% (max)
  • Manganese – 0.95% (max)

Schedule 40 Pipe Grades

Schedule 40 steel pipe is available in various grades, each tailored for specific applications based on their chemical compositions and mechanical properties. Here are some of the commonly used grades of Schedule 40 steel pipes:

ASTM A53 Grade A and B: The most commonly used grades for Schedule 40 steel pipes are made from low carbon steel, incorporating elements such as carbon, manganese, phosphorus, sulfur, copper, nickel, chromium, and molybdenum. These grades offer good strength and ductility, making them suitable for a wide range of general-purpose applications.

ASTM A106 Grade B: ASTM A106 Grade B is a type of steel pipe made from carbon steel, commonly used for high-temperature applications. Its chemical composition includes carbon, manganese, phosphorus, sulfur, silicon, chromium, and copper, making it well-suited for withstanding high temperatures.


API 5L Grade B is a carbon steel grade commonly used in the oil and gas industry for transporting fluids and gasses. Its chemical composition includes carbon, manganese, phosphorus, sulfur, silicon, and copper, which provide the necessary properties for efficient fluid and gas transportation.

ASTM A333 Grade 6 is a low alloy steel commonly used for low-temperature applications. Its chemical composition includes carbon, manganese, phosphorus, sulfur, silicon, nickel, and chromium, providing excellent toughness in cold environments

ASTM A500 Grade B, crafted from carbon steel, is frequently employed in structural applications like building construction. Its chemical makeup comprises carbon, manganese, phosphorus, sulfur, and copper. Selecting the right grade of schedule 40 steel pipe is crucial to meet specific application requirements for optimal performance and durability.

Schedule 40 Pipe Applications

Schedule 40 steel pipes are versatile and widely used:

  1. Plumbing & Water Systems: For hot/cold water in various settings.
  2. HVAC Systems: Efficiently distribute hot/cold air.
  3. Oil & Gas: Crucial for fluid transport in industries.

Frequently Asked Questions

What does Sch 40 mean?

Sch40 simply tells you the strength of a pipe. It means it can handle 40 kg of pressure. You can easily identify it by its thickness of 4.0mm. Pipes of various diameters, pressures, and wall thicknesses fall under Sch40. Check out the Pipes Schedule 40 chart for dimensions, weight, and pipe wall thickness. You can also use the Steel Metal Weight Calculator.

What's the formula for pipe schedule?

To find the pipe schedule, use the formula SCH = 1000(P/S), where P is the service pressure and S is the stress. Both are measured in pounds per square inch (psi), and SCH is short for pipe schedule.

How thick is a SCH 40 pipe?

A Sch40 pipe has a thickness of 4 mm. The “40” in Sch40 means it can withstand 40 kg of pressure. It has a standard thickness of 4 mm. ANSI B36.10 lists wall thickness in ten levels: Sch10, Sch20, Sch30, Sch40, Sch60, Sch80, Sch100, Sch120, Sch140, and Sch160.

Is Schedule 40 PVC or CPVC?

CPVC and PVC may look similar, but they have differences. Both types come with plain end and bell end options, and they’re available in Schedule 40 and Schedule 80 thickness. Schedule 40 PVC even has Class 125 fittings. PVC comes in lengths of 10 ft and 20 ft.

What are Schedule 40 and 80 pipes?

Schedule 40 pipes have thinner walls compared to Schedule 80 pipes of the same size. This means less material, possibly resulting in a weaker product. If the integrity of the plumbing is crucial for your intended use, you might need to consider this when choosing between Schedule 40 and 80.
