PIPE SCHEDULE WRITTEN BY MATT MILBURY ON 18 JANUARY 2016. POSTED IN PIPE Pipe Schedule is the term used to describe the thickness of a pipe. The outside diameter of a pipe is the same for all schedules in a particular nominal pipe diameter. Standard standard pipe schedules or pipes sizes as given by ANSI / ASME B36.10M and API 5L. There are eleven schedule numbers commonly used: 5, 10, 20, 30, 40, 60, 80, 100, 120, 140, & 160. The most popular schedule, by far, is 40. For pipe 8-inches and under, Schedule 40 and standard weight pipe wall thicknesses are the same. Schedules 5, 60, 100, 120, & 140 are rarely used. This should be considered when piping is specified for a particular project. The schedule number is defined as the approximate value of the expression: Schedule number = (1,000)(P/S) Where, P = the internal working pressure, psig S = the allowable stress (psi) for the material of construction at the conditions of use. For example, the schedule number of ordinary steel pipe having an allowable stress of 10,000 psi for use at a working pressure of 350 psig would be: Schedule number = (1,000)(350/10,000) = 35 (approx. 40) Note that the pipe is not always the "weakest link" in a piping system but this should be examined each and every time pipe is sized. METHOD FOR DETERMING SCHEDULE Measure the inside diameter and divide it by the wall thickness. (inches) R = ID/Thickness Pipe Schedule R Schedule 30 40-50 Schedule 40 29-39 Schedule 60 25-29 Schedule 80 20-23 Schedule 100 16-18 Schedule 120 13-15 Schedule 140 11-13 Schedule 160 9-11 STANDARDS API Standards API Spec 5L - Specification for Line Pipe ASME Standards ASME B36.10M - Welded and Seamless Wrought Steel Pipe

@RichGT350r 3 года назад

Pipe schedule - The OD stays the same IE, 6” Schedule 40 steel pipe = 6 5/8” OD x .280 wall. 6” Schedule 80 steel pipe = 6 5/8” OD x .432 When you hit 14” and above, the od will be 14”, 16” would be 16” etc. Tubing is always od x wall thickness. 6” is 6” od x the wall thickness. I hope this helps. Pipe size, the od doesn’t change based on Schedule. The wall thickness changes by Schedule. Thanks for sharing 👍

@robmadison4985 3 года назад

You're right, pipe sizes are designed so that the I.D. of schedule 40 pipe will be close to (but not exactly) the nominal size. It's confusing, but like you said 6" Sch40 is .280 wall and 6-5/8 OD which makes the I.D. 6.065". But all 6" pipe will be 6-5/8" OD regardless of schedule, so 6" Sch80 will have an ID of 5.761". 4" Pipe will always be 4-1/2" OD. Sch40 wall thickness is .237, making the ID 4.026" 4" Sch80 wall thickness is .337, making the ID 3.826"

@TrollworksForge 3 года назад

Pipe schedule is based on bursting pressure rating: it takes a thicker wall to resist higher pressure. Also, the larger the diameter, the greater the area (same # pounds, but more square inches trying to constrain it) so greater wall thickness needed. 2" sch80 is 0.218" thick, 6" sch80 is 0.432" thick. "So the pipe thickness which would hold 600psi at 15 ksi material strength was designated as schedule 600/15= 40."

@newslavecity8311 6 месяцев назад

no your wrong, its not the bursting pressure. its the design pressure. the bursting pressure would be higher than the schedule. it wouldn't make sense to engineer something that fails at its max design. if i can explain it simple for u, a 2 ton jack is rated as 2 ton because its design load is 2 tons, that doesnt mean it fails or "bursts" at 2 tons, it wouldnt make sense to sell a 2 ton jack that fails at 2 tons. it would fail maybe at like 2.5 tons or more. also take as an example the hauling capacity of a pickup truck. say its a truck that is designed to haul 4 thousand pounds. that means its design load is 4 thousand pounds, but of course uve seen people push that limit and overload their trucks, the truck doesnt fail because its design load is 4 thousand pounds but thats not its failing point. u would have to put 6-8 thousand pounds in the truck before it "fails" or something breaks. so i hope u understand the schedule is not the bursting pressure but rather its design pressure. just like a car tire say it says 40psi, that doesnt mean the tire bursts as soon as it hits 41 psi, u would have to reach near 100 psi or more before a bubble forms or it bursts. everything else u said is basically right though. it does take thicker material to maintain that design in wider pipes compared to small pipes. as an example when u step on a lego piece it hurts because it not flexible and feels like a rock. but if u take that same plastic and make it into a 1 foot box the same thickness as the lego piece it will be a super flimsy plastic box. in order to make a 1 foot box that is the same sturdiness as the lego piece the walls would have to be a quarter inch thick maybe more compared to the lego piece that the walls are only 2mm thick. hope that helps

You might also cover metal type-steel; cold rolled, hot rolled or extruded. some pipe, tubing, and hollow shapes are welded or extruded. stainless steel, aluminums Corten steels, galvanized(which releases toxic gas when welded) AISC is a good reference.

@jasonmascarenaz9678 3 года назад

Thanks for the video. I wasn't aware of the difference between I-beams and S-beams.

@scottwade3904 3 года назад

For Structural Steel.. .."I" Beams don't exist. "S" shapes are typically for crane rails, the inside profile of the flanges is more like the slope on channel sections. The nominal depth for W sections isn't within +/-.05" for the lighter weight sections the actual depth is usually about +/- 1/2". For example a W12x30 is actually 12 - 3/8 deep. WT's are cut from W shapes. HSS above 12x12 in size is usually a special order.

@erich9111 3 года назад

Your best bet for learning shapes is to browse the information published by the suppliers. Alro's website is awesome, and you can always call them to get more explanation. There are too many variations to describe in a video, and this video has a few discrepancies with what is available in from my research of suppliers in the Detroit area. Schedule is based on the pressure the pipe can withstand, so larger diameters need a thicker wall. Larger circumference means more hoop stress.

Correction on pipe thickness. Because it's nominal size, 2" standard wall (sch 40) will have a 2" ID and aprox 0.153" wall thickness. However sch 80 will have aprox a 0.218" wall thickness and something akin to 1-7/8" ID. OD on the example will be the same (2-3/8" approximately). Coming from expirence doing pipeline and natural gas distribution.

@BGraves 3 года назад

Open the AISC structural shapes pdf and all of the standard callouts here are defined. CAD guys: measure the ACTUAL dimensions of the stock. W12 will NEVER be 12" and different from one steel mill to another. Depending on what you are designing this can be critical in making sure the fabricators don't have to do extra coping rework or gap filling to achieve the final dimension on the drawing after the Sawyer already performed the cuts accordingly. USA users, look up the pdf for "Naming Convention for Structural Steel Products for Use in Electronic Data Interchange (EDI)"

I think the S beam and I beam are mixed up. The S has thick tapered flanges, and the I beam is called a W beam (for “wide flange”) with flatter wide flanges. We usually just use S sections for monorails, and W sections for structural beams and columns. H sections are mostly just for piles.

If I'm not mistaken, schedule refers to the pressure the pipe is rated for. As the pipe diameter increases, the thickness must also increase.

@ppapalos Год назад

I suppose schedule reffers to not only diameter but the use is going to go into so during different code or stresses to the pipe the outside diameter gets thicker??

@jamesbrandon8520 3 года назад

The schedule is for rating the pressure so the bigger the pipe it has to be thicker to handle the pressure so if you had something that was needing 1500psi and that required schedule 80 it wouldn’t matter if it was 2” or 12” pipe as long as you used schedule 80, and after 12” pipe once you hit 14” it changes to OD like tubing and also the tubing that I work with is mill wall thickness not schedule so if you have a tube that’s 2” x mw .125 you would have a 2” tube that’s an 1/8” thick, I enjoyed the talk on beams though it kind cleared some things up with me

In March 1927, the American Standards Association surveyed industry and created a system that designated wall thicknesses based on smaller steps between sizes. The designation known as nominal pipe size replaced iron pipe size, and the term schedule (SCH) was invented to specify the nominal wall thickness of pipe.

So, this is from hardhatengineer.com... "Definition of Schedule Number: The schedule number indicates approximate value of the expression 1000 x P/S where P is the service pressure and S is the allowable stress, both expressed in pounds per square inch." From that, I would think the following would make sense... but this is only an educated guess. So for a schedule 40 pipe, 40 = 1000 x P/S. Therefore if you rearrange the formula and reduce, P=0.040S. In other words for a schedule 40 pipe the wall thickness is designed such that the allowable internal pressure (P) would be 0.040 or 4% of the allowable stress (S) It would stand to reason that for a schedule 80 pipe the allowable pressure would be 8% of the allowable stress and for schedule 160 pipe the allowable pressure would be 16% of the allowable stress. This does not directly relate to a wall thickness, but would help to produce, perhaps a moment of inertia or a section modulus that would be used to generate wall thickness with additional calculations. In the process of doing so, the OD stays the same so fittings work across the pipe size range, but the ID changes due to varying wall thickness to produce the pressure to stress relationship (schedule), which affects internal volume and flow.
