What is difference between pipe and tube; difference between rod and bar?
Pipe - something used for household things like gas or heating or water. Tube - general term for something hollow and rounded. Like a toilet roll. Rod - Beats me Bar - don't know. Wow. Good question.
What is the difference between a pipe and a tube, and also between a rod and a wire?
PIPE AND TUBETube = measured by outside diameterpipe= measured by inside diameter2.ROD AND WIREDiameter is less than 10mm is WIRE.Diameter is greater than 10mm is ROD
What is the difference between a tube cutter and a pipe cutter?
A tubing cutter is used mostly on copper tubing (but can also be used on stainless steel tubing). The pipe cutter you described (with chain on it) is normally called a pipe snapper. This is used only on cast iron pipe. A pipe cutter is a heavier version of the tubing cutter and is used to cut steel pipe such as black iron pipe and galvanized steel pipe. A pipe cutter has a tee handle that you turn to tighten the cutter wheel while a tubing cutter has a round, knob type, handle to tighten the wheel onto the material.
What is difference between 150# pipe and 300#pipe of same pipe class?
Pipe does not have a class like a flange. There basically is no 150# pipe. The pressure rating for pipe is determined by calculation taking into consideration its material, size, wall thickness, temperature and the code to which you are designing. In some cases the limitation of the pipe design is structural (such as support) rather than pressure. You really need to do some research on piping design to better understand the problem.
Difference between casing and pipe and tube?
The cleanest way to define the differences is by the ASTM or API standards that the various items are manufactured to. It is correct that pipe sizes are based on inside diameter up to 14 inches then it is based on outside diameter. Tubing is always based on outside diameter. Casing has its own set of dimensions that are based on outside diameter.
What is the difference between a hose, a tube and a pipe?
Difference between Pipe and TubeIn common usage the words pipe and tube are usually interchangeable, but in industry and engineering, the terms are uniquely defined.In short: Tube is measured by outside diameter, the pipe is measured by nominal diameter.Pipe is generally specified by a Nominal Pipe Size (NPS) indicating a constant Outside Diameter (OD) and a Schedule (SCH) that defines the pipe wall thickness. Nominal Pipe Size (NPS) and Outside Diameter (OD) values are not always equal.For NPS ⅛ to 12 – The NPS and OD values are different.For NPS 14 and above – The NPS and OD values are equal.Pipes are usually rigid and have no flexibility.Tube is most often specified by the Outside Diameter (OD) and wall thickness, but may be specified by any two of Outside Diameter (OD), Inside Diameter (ID), and Wall Thickness (WT). In tubing, OD is an important and exact number. The measured OD and stated OD are either exactly same or within very close tolerances of each other. Tubing is usually more expensive than pipe due to tighter manufacturing tolerances. Tube can be both rigid and flexible.Pipes accommodate larger applications with sizes ranging from a half-inch to several feet. Tubes are generally used in applications that require smaller diameters. While 10-inch pipes are common, it’s rare that you will come across a 10-inch tube. The tolerances in various pipe dimensions are comparatively more relaxed as compared to that of tubes. Here the tolerance refers to diameter tolerance, wall thickness tolerance, straightness tolerance, roundness tolerance etc. Also generally the outer and inner surfaces of tubes are much more smoother than that of compared to pipes. Pipe assemblies are almost always constructed with the use of fittings such as elbows, tees, and so on, while tube may be formed or bent into custom configurations.Source - Introduction to Pipe - The Process Piping
What's the difference between a steel pipe and a steel tube?
A pipe is a vessel. A tube is structural. A pipe is measured ID "Inside Diameter". A tube is measured OD "Outside Diameter". How they are measured... Pipes are measured ID or inside diameter because they are vessels. Tubes are measured OD or outside diameter because they are structural. Pipes have a consistent ID regardless of wall thickness. In other words, a 1/2" high pressure pipe may need a 2" thick wall, but the ID will still only be 1/2" even tho the OD is 4.5". Generally speaking, a tube will have a consistent OD and it's ID will change. Engineers see tubes and pipes with different eyes. A tube is structural. By having a consistent OD they can vary wall thickness, changing the ID, to increase strength. Because they are consistent OD, they have predictable characteristics. Again, the difference is simple, it's how they are measured and what their intended uses are.
What is the difference between a pipe and a shaft?
A pipe is a conduit (usually round) that allows flow of a fluid (liquid or gas) or semi-solid from one point to another. A pipe needs to have a hollow cross section in order to allow passage of fluid.When compared to a pipe, a shaft would ideally be a round bar (not necessarily round though), with hollow or solid cross section, used to transmit rotary power.
