Schedule 40 Steel Pipe dimensions, weight and pressure (2024)

ANSI/ ASME B36.10 Schedule 40 Carbon Steel Pipe chart, dimensions, weight and wall thickness

What is the meaning of SCH 40 in a pipe?

Sch40 in a pipe indicates tensile strength, 40 kg pressure. It is indicated through standard thickness of 4.0mm.
ANSI B36.10 wall thickness: Sch10, Sch20, Sch30, Sch40, Sch60, Sch80, Sch100, Sch120, Sch140, Sch160 ten levels.

What is the difference between sch 40 & sch 80 Pipe?

Sch 40 and sch 80 pipe are made from the same material. The difference in structure lies in the thickness of pipe wall; the higher the schedule, the thicker the wall of the pipe.

Meaning of Schedule 40 pipe?

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 and a wall thickness of 0.437 inches (11.1 mm).
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.) pipes are specified by using the NPS and sch numbers. It is the schedule number that shows the approximate inside diameter.

What are Pipe Schedules?

The schedule number on pipe is related to the thickness of the pipe wall as the number increases, the wall thickness becomes thicker.
The actual wall thickness will be different but the schedule number can be the same on different pipe size. Below is the examples of it.

• 1.000 inch x Sch 40 Pipe – actual wall thk is 0.133”
• 1.000 inch x Sch 80 Pipe – actual wall thk is 0.179”
• 2.000 inch x Sch 40 Pipe – actual wall thk is 0.145”
• 2.000 inch x Sch 80 Pipe – actual wall thk is 0.218”

Relationship between pipe size, schedules, and wall thicknesses is simply to refer to the below conversion chart

There are various schedule numbers which are used on pipes, such as Sch 5, 5S, 10, 20, 30, 40, 60, 80, 100, 120, 140, 160, STD, XS, and XXS. The most common sch’s used are STD, SCH 40 and SCH 80.

What does Nominal Pipe Size or NPS mean?

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

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

FAQ

Tools you should require to cut and thread the pipe

1. Pipe cutter: It is utilized to cut copper or plastic pipe but it can also be used to cut steel and any kind of metal if chosen the correct type of pipe cutter.
2. Angle Grinder: It is a powerful tool which is useful to remove old pipe from a compact space. While working with it, it is suggested to used protective googles, earplugs and gloves.

Assure that you use right wheel for cutting metal pipe

1. Hacksaw: It is bit more precise and tougher to use as compared to the above. It is quality tool which is utilized to cut steel pipe and other such material.
   It appear like a mini-saw with a handle attached to its one end and the blade is on the other end of the handle and it is used to saw the pipe, which makes a smooth edges and it doesn’t required any more processing once the cutting has done.
2. Circular Saw: It is only utilized for cutting pipe with a diameter of ½” or less. Its initial step is to regulate if the circular saw has any teeth on the blade.
   And if it does not have, then abrasive disc or sandpaper on the blade is used even electric drill can be used to file if needed.
3. Table Saw: As the steel pipe are very hard and resists bending and cutting. And it also has sharp edges which can tear at an average bit of pressure.

So if you cut steel pipe with a table saw, than it is not going to be gentle on your hands or on your tools and it will also take much longer time as compared to cut with a circular saw.

Tools which can be used to thread the pipe are

1. Pipe threader: It is device which is used to cut groove or threads the pipe ends
2. Mechanical Pipe Threader: It is a good choice for soft and lightweight pipe material to thread. It is utilized for the capacity of up to 2” pipe.
3. Power Threader: It is used to thread broad range of pipe including stainless steel, black, galvanized, along with and heavy-wall pipe.
   It has the following parts:
   · Carriage and carriage hand wheel
   · Die head
   · Front and rear chuck
   · On/Off switch
4. Hand Held Threader: It is same as the mechanical pipe threader.
   The sole difference is that its die head revolve automatically by electric power and due to which it is faster and requires less physical force as compared to mechanical pipe threader.
   It has the following parts:

• Forward/reverse switch
• Handle
• Grease fitting
• Torque arm for attachment

Follow these 4 things to join pipe sections properly

• Brazed joint: It is the process of jointing pipes by utilizing a molten filler material at above 840°C. It is usually used for joining copper pipes.
• Brazed joint mechanical strength is low as compared to other joints. It is appropriate for average range of temperature areas.
• Compression joint: It is a kind of pipe joint which uses an outer screw thread to flatten the two ends together. It is used for low-pressure applications at the range of -5 psi to 125 psi.

The compression joint can be used in air conditioning, refrigeration, and plumbing systems because it can be simply dismantled for maintenance or replacement if corrosion takes place.

• Flanged joint: It is a type of joint which secures the pipe by external screws, by giving an additional joint support for conveying of substances at higher pressure.
• Grooved joint: It joints two pipes. A small groove is made at the pipe end with a grooving machine.
  
• A rubber gasket is fitted around the pipe ends and around it a two-part coupling is screwed together with two bolts and nuts.
  
• The coupling parts, are produced to fit in the grooves which evenly lock the pipes together and the rubber gasket creates which makes the connection secured by air and water.
  
• Threaded joint: It connects the pipe by screwing with the help of threads furnish to each pipe. One pipe has internal threads whereas other will have external threads. Welded joint (butt welded, socket welded): It is the most common kind of welding. It is used to join the pipes when it is of same diameter. Expert workers will be required to install the joint.

It is useful for large commercials and industrial piping systems.

Can I use tape or sealant?

Pipe thread sealant tape, is even known as Teflon tape. It is a popular type of pipe sealant which is available in a roll just as masking tape of electrical tape.

It is a nonstick, white tape that absolutely provide as a lubricant as the threaded parts of a piping system can be attached.

Which 6 safety precautions you should take during installation of Schedule 40 pipes

1. Conduct Regular Safety Training: To increase awareness about on-site safety and strengthen learning in employees, employers must arrange a safety training regularly.
2. Promote corporate safety company: Safety is crucial at piping installation to avert dangerous situation which can harm to the workers. The safety must come before the work and not to its contrary.
3. It should be the responsibility of managers and supervisors to inspire this awareness in employees by giving example, giving rewards, and present the consequences where required.
4. Ensure proper pipeline revealing method: Proper pipeline revealing method must be followed in order to stop hazardous situation at the site.
5. Heavy machinery used must be serviced as at when due and engineers must be sufficiently trained to use so.
6. Explosions or environmental contamination can happen when a heavy machinery damages an underground pipeline. Hence, all utilities buried underground must be compatible and marked prior to start working.
