Because threading thin wall pipe renders the pressure rating ineffective, as it thins the wall to much to be able to withstand the pressure.

What gauge is schedule 40 pipe?
10
What is the difference between schedule 40 and 10 gauge pipe?
The gauge of the pipe is the wall thickness. It is easier to say Schedule 40 pipe than .180 inch wall thickness. This is the SCH 40 wall thickness for a standard 12" pipe and the actual gauge thickness will vary based on pipe size and material. The larger the Schedule number, the thicker the pipe wall thickness. Pipe Schedule is also expressed in Std., X-Stg., and XX-Stg. since some thicknesses are more common than others.
What is mean by schedule 80 for Pipes?
Thicker pipe wall is required to contain higher fluid pressures. For the same fluid pressure, a thicker pipe wall is required for a larger diameter pipe than that required for a pipe of smaller diameter. A schedule of pipe sizes and wall thicknesses has been established by ASTM standards governing manufacturing of pipe. A previous description of pipe wall thicknesses as "Standard", "Extra Strong" and "Double Extra Strong" has been supplanted by a schedule of 10, 20, 30, 40 60, 80, 100, 120 and 160. Schedule 40 pipe generally compares with the previous use of "Standard". For metal pipe, Schedule 80 pipe has a thicker wall and can withstand greater pressures than a Sch 40 pipe. A point of confusion is that for PVC piping, Schedule 80 pipe has a thinner wall than Sch 40 pipe.
What is the pressure rating for Schedule 10 steel pipe?
The fittings THREADED are normally rated for 125 PSI but there are ratings over 3,000 PSI if needed such as high pressure steam applications Then one has to take temperature /pressure relationship into consideration higher temperature greater pressure
What is the OD of 4 inch schedule pipe?
Schedule 40 Pipe O.D. through 12" Size (inch) O.D. (inch) ------ ------------ 3/4 1.050 1 1.315 1-1/4 1.660 1-1/2 1.900 2 2.375 2-1/2 2.875 3 3.500 4 4.500 5 5.563 6 6.625 8 8.625 10 10.750 12 12.750 Charts with the larger sizes are readily available online
What gauge is schedule 40 pipe?
10
What is schedule 40 black pipe?
Steel pipe that is schedule 40, means that the steel pipe has a certain amount of threads on it. It also means that it can't be longer than about 10 feet.
What are 3 common schedules for iron pipe?
Schedule 10 , 40 and 120
What is the schedule of 16 gauge pipe?
16 gauge pipe refers to the wall thickness of the pipe exclusive of its diameter.It is 0.064 inches thick, this is a steel wire gauge measurement.Pipes are typically sold by schedule numbers. A wall thickness of 0.064 inches would correspond to pipe schedule 40 for 1/8" diameter pipe (0.068"), schedule 10 for 1/4" and 3/8" pipe (0.065") and schedule 5 for pipe diameters 1/2" to 2" (0.065"). Over 2" diameter pipe, schedule 5 (the smallest wall thickness) is thicker than 16 gauge steel.

What schedule 10 ,20, 40, 80, 120????

What is the difference between astm a53 astm a120 in thickness of pipe?
The difference in thickness is not by the ASTM grade, but rather by the term "Schedule" - as in Schedule's 10, 40, and 80 - with schedule 10 having the lighest wall thickness, and schedule 80 having the thickest.

Does black steel pipe have the same pressure capacity as schedule 40 steel pipe?
What does the schedule have to do with the material as schedule is the wall thickness Schedule 10, 20, 40 80 and 120 (XXH) The Schedule is telling you the wall (INTERNAL) thickness 10, 20 40, 80 and 120 XXH Whether it be steel, brass, galvanized and wrought ` About the pressure capacity, it is not the same because every material such as steel, brass, galvanized or wrought has a different strenght of materials.
Does black steel pipe have the same pressure capacity as schedule 80 steel pipe?
Hello??? black steel comes in various schedules , schedule 10, 20 40 ,80 ,120 the thicker the wall the higher the pressure the piping can withstand
What is the pressure rating for Schedule 10 steel pipe?
The fittings THREADED are normally rated for 125 PSI but there are ratings over 3,000 PSI if needed such as high pressure steam applications Then one has to take temperature /pressure relationship into consideration higher temperature greater pressure
Why is pipe thickness mentioned by schedule and what does it mean?
schedule is thickness of the inside diameter of the pipe,schelude 40 is usually a standard thickness for most applications which is normally 1/4" wall,as the schedule number increases or decreases so does the wall thickness,the outside diameter remains the same,standard piping schedules are 10,40,80,120,160 ========================================= ***This question came up at work the other day and in searching for an answer I found that a lot of people have the same question... I finally found an explanation on a website (I have included the paragraph and link below). I can not confirm its accuracy; however, it makes more sense than anythign else out there that I've read. Schedule is NOT directly a measure of thickness, it is a measure of the pressure a pipe can withstand without deflection or failure. When you are talking about pipes constructed of the same materials (i.e. PVC) a thicker pipe would be able to withstand higher pressures. As a result, many people have taken "schedule" to be synonymous with thickness. "For the purpose of standardizing pipe dimensions, the American National Standards Institute (ANSI) sponsored by the American Society for Testing Materials (ASTM) and the American Society of Mechanical Engineers (ASME), published ANSI B36.10. To broaden the range of wall thicknesses, schedule numbers from schedule 10 (S.10) thru schedule 160 (S.160) were adopted for steel pipe. These schedule numbers indicate approximate values for 1000 times pressure-stress ratios." From http://www.durovac.com/industrial-vacuum/tubing-fittings/stuff-about-pipe.htm
