Article Introduction
Now living conditions have improved, and basically every household will install a water heater. However, when installing a water heater, you need to buy a hot water pipe. You may not know what material to buy. Plastics have been very hot these years, but you may be wondering if you can install your own water heaters with plastic tubes. If using a plastic tube, which material is used?
Please read the following article carefully to learn more about plastic pipes！
What kinds of plastic tubes are there?
1. Polyvinylchlorid (PVC PIPE FITTING)
PVC pipe, full name Polyvinylchlorid, referred to as PVC, is a pipe system made of polyvinyl chloride (PVC). The main component of PVC pipe is polyvinyl chloride, which has the following characteristics: strong corrosion resistance, easy bonding, low price, and hard texture.
Application areas: water supply system, drainage system, industrial field.
2. Chlorinated Polyvinyl Chloride (CPVC PIPE FITTING)
CPVC pipes are pipes made of PVC-C resin as the main material. CPVC pipes have the characteristics of heat resistance, acid, alkali, salt, oxidant and other corrosion resistance, and their heat deformation temperature and mechanical properties are higher than UPVC. CPVC pipes have the following main characteristics: high temperature resistance, flame retardancy, insulation performance, corrosion resistance, and environmental protection.
CPVC pipes are widely used in the following fields: industrial pipeline systems, fire protection systems, and power cable protection.
3. Polypropylene-Homo (PPH PIPE FITTING)
PPH pipe is a β-modified high molecular weight, low melt flow rate polypropylene material with a uniform and delicate Beta crystal structure. This structure makes PPH pipe have excellent chemical corrosion resistance, wear resistance, good insulation, high temperature resistance and other characteristics. Its working temperature can reach 100℃, and it is non-toxic, light in weight, easy to transport and install.
4. Low density polyethylene (PPR PIPE FITTING)
PPR pipe is a commonly used water pipe material. PPR pipe has the following main features and uses: good high temperature and pressure resistance, environmental protection and health, easy installation, long service life, and good thermal insulation performance.
PPR pipe is widely used in the following fields: drinking water pipe, hot and cold water pipe, heating system, chemical system.
5. Polypropylene (PP IRRIGATION PIPE FITTING)
PP irrigation pipe is a pipe made of thermoplastic polypropylene. Polypropylene is a lightweight, high-strength, corrosion-resistant material with the following characteristics: chemical resistance, high temperature resistance, low temperature resistance, light weight, good mechanical properties, plasticity, and environmental protection.
PP irrigation pipes are widely used in agricultural irrigation systems and other occasions that require the transportation of water or other chemical liquids due to their excellent performance. For example: agricultural irrigation, industrial applications.
Can PVC pipes and PVC pipe joints be used as hot water pipes?
PVC pipe and PVC pipe joint are easy to break and deform. In fact, it is a plastic tube, and the interface is usually glued. Because of its poor resistance to freezing and heat, it is difficult to use as a hot water pipe; strength is not suitable for the pressure requirements of water pipes, so cold water pipes are rarely used. In most cases, PVC pipes are suitable for wire and sewage pipes.
Which material is suitable for hot water pipes?
The PPR pipes and CPVC pipes is relatively better
The PPR tube is a new type of water pipe material that can be used both as a cold pipe and as a hot water pipe. Due to its non-toxic, light weight, pressure resistance and corrosion resistance, it is becoming a popular material. Also suitable for hot water pipes, even pure drinking water pipes. The interface of the PPR tube is made by hot melt technology, and the tubes are completely integrated together. Therefore, once the installation pressure test is passed, it will not exist as long as the aluminum-plastic tube and the PPR tube will not scale.
CPVC pipes have a wide operating temperature range, and can be used between -40℃ and 95℃. They have excellent high and low temperature resistance, low thermal conductivity, and good thermal insulation performance. The inner wall of CPVC pipes is smooth, with low flow resistance, not easy to breed bacteria, and has excellent hydraulic performance.
Summary
While PVC is excellent for water service lines and DWV applications, it’s not recommended for hot-water distribution systems because it can only withstand temperatures up to 140℉. CPVC and PPR, however, can withstand temperatures up to 200℉，Therefore, when purchasing plastic pipe fittings, you need to make corresponding selections and purchases based on the application field and particularity.
Buying a product requires buying a regular company, just in case a fake is bought, causing a big problem. If you want to buy products made of different plastic pipes, you can always consult us. SAM-UK will explain to you the most suitable products.
