Aluminum-plastic composite pipe is a pipe that uses welded aluminum pipe as the middle layer, and the inner and outer layers are polyethylene plastic. It uses a special hot melt and is made into one by extrusion molding. . ?
The advantages of aluminum-plastic pipes are:
A. Good temperature and pressure resistance, wide operating temperature range;
B. , 100% insulating gas penetration, impermeable to oxygen and light;
C. Hygienic and safe, no tartar build-up. Through the use of an aluminum core, it completely isolates air and inhibits bacterial growth;
C. p>
D. The inner wall is smooth, the water pressure loss is small, and there is no water hammer sound;
E. The pipe can be arbitrarily long and bent as desired, saving pipe. fittings and joints, and the probability ofe leakage is small;
F. Metal pipes have considerable strength and are easy to bend. They do not bounce back after folding, are easy to install and simple to maintain;
G. Good thermal insulation performance, saving external insulation materials;
H, long service life, up to 50 years;
3. The (PE-X) pipe is manufactured by adding a silane cross-linking agent to high-density polyethylene raw material to transform the linear structure into a three-dimensional cross-linked pipe. The network-like structure of polyethylene improves the overall performance of the pipe. pipe.
4. The advantages of PE-X pipe are:
A. Good high and low temperature performance, applicable temperature range: -70~+110℃.
B. The texture is hard and tough, with high resistance to internal pressure.
C. Good resistance to chemical corrosion and excellent resistance to fissuration under environmental constraints.
D. No rust or scale.
5. You can choose according to your region. Generally speaking, aluminum-plastic pipes are more frost-resistant, but to achieve a good thermal insulation effect and be easy to use in winter, you should also choose. a high-quality solar brand and add thermal insulation cotton and thermal insulation and anti-fall modules, etc.
Solar water heater\x0d\ There are many options for installing water pipes, such as PPR water pipes, copper pipes, copper pipes -plastic (aluminum-plastic pipes), PVC pipes, iron. pipes, etc \x0d\In fact, considering various factors, PPR water pipes are quite ideal. The reason is also very simple. Firstly, the quality of good PPR water pipes is very reliable, which is quite comparable to that ofs copper pipes. Secondly, the price is more acceptable and much lower than copper pipes; that it is healthy, without any rust or patina. \x0d\Note, the water line must be 6 points. PPR water pipes are divided into cold water pipes and hot water pipes. The key is the thickness of the pipe wall. It is recommended that everyone use hot water pipes for drainage at home. the price is not much more expensive. \x0d\ Considering that solar water pipes must be antifreeze, meaning they cannot freeze and crack under normal circumstances, there are only three types of pipes on the market: true reticulated pipes PEX, PERT pipes and PB pipes. . \x0d\At present, most of the market uses PEX as solar water pipes, because it is frost-resistant and the price is relatively low. However, over the last twoOver the years, many manufacturers have significantly reduced their degree of crosslinking. in order to be competitive in the market, thereby reducing costs., but at the same time, its antifreeze performance is also significantly reduced. If you use it, it is recommended not to choose one with less than 140 yuan. The antifreeze performance of PERT is better than that of PEX, but the cost is relatively higher, so they are rarely used in the market at present; solar and PB pipes should be considered the best anti-freeze pipes on the market. They are now used in many high-end underfloor heating projects. Of course, their costs are higher and they cannot currently be promoted in the solar industry. \x0d\ Therefore, it is recommended to choose higher quality PEX cross-linked pipes, as long as you are not trying to be cheap. \x0d\PPR cannot be used as yousolar water supply and drainage systems. It will freeze and crack in one winter in the north (it can be used in the south). \x0d\Aluminum-plastic pipes are no good either. Foshan Rifeng and Jinde used them for only four to five years in the north and south of the Yellow River, and only two or three years in the northeast. \x0d\But inside, for the sake of appearance and high indoor temperature, PPR or aluminum-plastic pipes can be used.
