A: Tubes can come in different shapes such as square, rectangular and cylindrical, whereas piping is always round. The circular shape of the pipe makes the pressure force evenly distributed. Pipes accommodate larger applications with sizes that range from a ½ inch to several feet.

A: Pipe is normally used to convey fluids, so the internal cross-sectional area (defined by the ID) is important. Tube is more frequently used in structures so the OD is the important number. Wall thickness under tolerance is up to 12.5% applied for all pipes as and welded fittings as per ASME B16.

A: Because of the materials that tubes are constructed from, such as aluminum, mild steel, brass, chrome, copper, or stainless steel, they are usually more expensive than pipes. Obviously, the end user price is influenced by the materials used.

A: Tube is measured by an exact outside diameter (OD) and wall thickness. Pipe is measured by a nominal outside diameter (also known as NPS or Nominal Pipe Size) and wall thickness.

A: For applications that require the strongest possible steel, tube is generally the way to go. It's known to be significantly stronger than pipe, and one of the strongest metal formats period.

A: Your intuition that the wall thickness and ID/OD effect the strength is correct. But if you have a pipe with identical dimensions as an HSS tube. The HSS(tube) will be stronger because it has higher Fy and higher Fu. Given pipe and tube of same material/strength properties, the manufacturing tolerances also matter.

A: Bevelling pipe ends helps to ensure that these welds are as strong as possible but it can be slow and hold up production when time is critical. Both speed and quality are important – bevelling must take place rapidly so that bottlenecks do not occur, yet it must meet high specifications to ensure welds are strong.

A: Hi, in pipes and fittings thickness calculation(as per ASME B31. 3) for semless pipes we go for mill tolerance of 12.5% in general.

A: The nominal dimension for pipe is the ID. So, 1½ inch pipe is NOT 1½ inch outside diameter, but instead is nominally, (approximately) 1½ inch inside diameter. Pipe is typically manufactured to looser tolerances and less expensive to purchase.

A: Tubing offers greater flexibility in systems with fewer connections, meaning fewer potential leak points. Tubing can usually be installed faster and cheaper than piping. Tubing is cut to length and then deburred, the fittings are tightened onto a nut.

A: The most common standard diameters are as follow: 0.5 inch (15 mm), 0.75 inch (20 mm), 1 inch (25 mm), 1.5 inch (40 mm), 2 inch (50 mm), 3 inch (80 mm), 4 inch (100 mm), 6 inch (150 mm), 8 inch (200 mm), 10 inch (250 mm), 12 inch (300 mm), 14 inch (350 mm), 16 inch (400 mm), 18 inch (450 mm), 20 inch (500 mm), 22 inch .

A: The size is almost always written somewhere on the sidewall of the tyre. Inner tubes typically state a wheel diameter and width range for which they will work, e.g. 26 x 1.95-2.125", indicating that the tube is intended to fit a 26 inch tyre with a width of between 1.95 inches and 2.125 inches.

A: The weak point is usually the connections. So, we'll focus today's lesson on pipe connections. Threaded pipe connections: If you look at the threads of a bolt under magnification, you would see that the threads are even along the entire blot.

A: So, a larger line has the potential to carry more water that can result in more stress. Still, smaller pipes have the potential to reach that pressure faster.

A: Barlow's Formula relates the internal pressure that a pipe can withstand to its dimensions and the strength of its materials. The formula is P= (2*T*S/D), where: P = pressure. S = allowable stress.

A: Thicker wall and bigger diameter put you in the right direction. The most popular suggestion here is filling the tube with concrete. This no doubt will get you a stronger member that is capable in flexing more and take more load without bucking the top or compression side of the tube.

A: The answer is round tube has a higher resistance to both flex and torsional twisting than square for a given weight. NB. Use ERW tubing as it is much, much stronger than CHS . If you have a round hole, putting the maximum size round tube through it will be stronger than its' square counterpart.

A: PE pipes feature ends typically cut at a 90-degree angle to the pipe run for a flat, even termination. In most cases, plain end pipes are used in combination with slip-on flanges and socket weld fittings and flanges.

A: At the end of any length of pipe, are the pipe ends. The most common pipe ends are: Plain End – for small pipe sizes (typically less than 2 inches (5cm)). Bevel End – for larger pipe sizes. Threaded End – for small pipe sizes (typically less than 2 inches (5cm)).

A: Having the inside dimensions (ID) and the outside dimensions (OD) will allow you to figure out the wall thickness on the tubing. You would need to subtract the ID from the OD and then divide by two. This number is the wall thickness.
