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? PVC pipe and PVC pipe couplings have been so hot in recent years. It seems to be very good. Can you use this?
What kinds of plastic tubes are there?
Can PVC pipes and PVC pipe joints be used as hot water pipes?
Which material is suitable for hot water pipes?
1. PET: polyethylene terephthalate
Often used to make mineral water bottles, cola beverage bottles, juice bottles, screen protectors and other transparent protective films, etc.
2. HDPE: high density polyethylene
Suitable for food and medicine, cleaning products and bath products, shopping bags, trash cans, etc.
3. PVC: polyvinyl chloride
PVC is now used to make some cheap artificial leather, foot mats, sewer pipes, etc.
4. Low density polyethylene (LDPE)
Plastic film and cling film, paper box, milk box, beverage box and other packaging boxes are used as inner film.
5. Polypropylene (PP)
The microwave lunch box is made of this material and can withstand high temperatures of 130 ° C and poor transparency. This is the only plastic box that can be placed in the microwave oven.
6. Polystyrene (PS)
Too high a temperature will release harmful substances, can not be put into the microwave to heat, do not use it to install hot food, and can not contain strong acid (if juice) and strong alkaline substances.
7. Polycarbonate (PC)
It is synthesized from bisphenol A and diphenyl carbonate, and is commonly used in the manufacture of kettles, cups, bottles and the like.
8. Polyamide (PA)
Another name for polyamide: nylon - everyone must be familiar. The polyamide family is very strong and has many varieties with excellent physicochemical properties.
9. ABS resin
There are many types of ABS, which are widely used in various electrical enclosures, office supplies components, helmets, doors and windows, etc. In industry, ABS is often used for blending and modification of other plastics.
10. Blend (XX-XX alloy)
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.
The PPR tube 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.
Buying a product requires buying a regular company, just in case a fake is bought, causing a big problem. PVC pipe and PVC pipe joints are very popular among you. If you want to buy, you can always consult us. We will explain to you the most suitable products.
