The 4 types of tubes ideal for your home.
How do I choose the type of tube that will be used in my home? Questions like these are quite common when thinking about your plumbing installation. To better guide you, we selected some of the most used types of tubes and their application so that doubts like these can be resolved.
Choosing the correct type of pipe in your plumbing project is very important. This can provide you with several advantages, such as safety, quality of life, economy, and thus avoid future problems with water and sewage.
1. PVC pipe
Polyvinyl Chloride, better known as PVC is one of the best known materials and the most used in homes when we talk about pipes, but is it suitable for all situations that arise in your home? Can it be used in, for example, hot water installations?
Brown PVC is the most used type of pipe when dealing with cold water, its type of material withstands working temperatures with an average of 20 °C. It has several advantages that justify its use in most installations: resistance to the action of fungi and bacteria, chemically inert, solid and light in handling. There are two different lines of this type of tube on the market: weldable and threadable.
The weldable line (brown) for cold water is very easy to handle, as it allows cold welding of tubes and connections, solving in a basic way changes in the direction of your installation.
The welding is carried out as follows: first, the desired location is cut and the surface to be welded is sanded; second, the surfaces are sanded until the shine disappears, and the cleaning is done, removing any impurities and grease with a cleaning solution; in a third moment, the adhesive is evenly distributed, avoiding over-application; finally, it snaps together the ends to be welded. It is advisable to wait 1 hour to fill the water pipe and 12 hours to do the pressure test.
The threadable line is also very easy to install, however, it is still less used than the weldable. To use this, a screw is needed to thread the ends of the tubes. It is then finished with thread sealing tape before joining the tubes, which are usually white in color.
2. CPVC tube:
CPVC – Chlorinated Polyvinyl Chloride – is a type of plastic tube, derived from PVC, which has a similar composition, but with the addition of chlorine in the chemical composition, making the pipe material more malleable and resistant to high temperatures. It is becoming a cheaper and faster-running alternative to copper pipes that were used in hot water pipes in homes in the past.
In addition, it has several physical properties. The main ones are: high resistance to corrosion and abrasion, chemical inertness, ease of working and excellent thermal insulation.
Like brown cold water PVC, CPVC is found in the weldable line. This makes it even easier to create connections quickly and without waste. The way to carry out the welding is similar to the brown PVC pipe illustrated above.
3. PEX tube:
PEX (crosslinked polyethylene) is a type of pipe widely used today because it is flexible, that is, it is capable of facilitating installation, as it does not depend on connections such as knee/elbow, and handling, as it is a light and lightweight material. adjustable size.
But what is the advantage of PEX when compared to other pipes in plumbing installations? PEX is most recommended for hot water systems, but it is still possible to use it in cold water systems. In addition, it features: high resistance to fatigue cracking, a long service life and a below-market running price.
On the other hand, polyethylene is currently the most expensive pipe material for hydrosanitary installations. It also has a deficiency in large water transport, that is, building systems outside the apartment, as the requirement for a thicker and more resistant material would compromise its flexibility.
4. Copper Tube:
Copper is also a material that is highlighted when we talk about hydro sanitary installations. As it is a great thermal insulator, it is always the first option when talking about hot water systems, but there are other data to analyze.
Despite being cheaper than polyethylene pipes, copper pipes still have a high value compared to poly chlorides and their installation is much more complicated, in addition to being poor acoustic insulators. For More Plumbing Services in Texas
However, there are still many positive points in this type of tube. Copper has a very long service life and, if installed correctly, will rarely need maintenance. By withstanding a higher temperature, it will not suffer deformations when coming in contact with hot water, so it is possible to rely more on performance calculations.
What’s more, copper is fully recyclable, making it a good choice when it comes to sustainability.
