What is a tube?
Tubes are great for transporting fluids or protecting electrical or optical connections and wires. Although slight differences exist, the words “pipe” and “tube” are practically identical – in general, a Tube has more stringent technical standards than a pipe.
In today’s fluid systems there are a lot more demands than they were years ago. Leaks that were once considered nuisances are now classified as air emissions or dangerous wastes, requiring factories to close.
The fundamental notions of tube joining haven’t changed that much over the years, even though modern processes require higher pressures, flow rates, and temperature requirements.
Some of the advantages of tubes are as follow below:
- Since the threads do not have to be cut with special tools, standard spanners are all that are needed to install the tube.
- Because of the smaller wall portions, tubes are easier to handle and bend.
- No threading tolerance is required in the tube, so the thickness is sufficient without sacrificing a thin tube.
- A gentle tube bend, on the other hand, reduces pressure drops while acute bends in elbows can cause big pressure drops because of disturbance and energy loss.
- In applications where there are many connections, such as in plumbing systems in homes, tubes are a more viable option than pipes.
- Pipes have compression fittings and joints that use glue to join them together. Tubing has no joints or fittings because it does not require any welding or glue.
- Instead, tubing is joined using a process called compression fitting, whereby the tube is placed into a fitting with no joint and then compressed using a compression fitting machine. This creates a very strong bond where there is no chance of leakage.
- Although tube fittings cost more than pipe components, tubing is generally the less expensive option. The reason is that systems have a lower downtime and are easier to install and remove.
- As industrial fluid systems become more complex and stricter, tubes offer a solution to these challenges. Tubing transports fluids in industrial applications, but tubes have several advantages over pipes. They are easier to install, are less expensive, and deliver better performance.
- Tube fittings serve as unions. When disassembling, the procedure is simple and risk-free. This, combined with a leak-tight seal, makes maintenance quick and hassle-free. Separating successive lengths of tubes and fittings is not necessary to remove a part from the system.
