The service life of plastic water pipes is only half of that of stainless steel outer wire tee fittings water pipes, and it is easy to shorten the service life due to external influences. This is mainly due to domestic plastic water pipe production technology and raw material quality reasons, resulting in uneven pipe quality. Plastic water pipes have a lifespan of only long-term durability according to standards without any external damage, while stainless steel water pipes can achieve the same age as the building. During installation, the hot-melt connection process is also a factor that shortens the service life of plastic water pipes. Hot-melt damage to the physical structure of plastic water pipes is also the most common cause of water leakage. The service life of damaged plastic water pipes is drastically reduced, and the service life can last for 15-20 years at most. In the 70-year use of the house, the plastic water pipes need to be replaced at least 2-3 times. The cost of decoration and maintenance is also a large investment. Stainless steel The characteristics of the outer wire three-way pipe fittings and the building are of the same age, which can guarantee the service life of the water pipe. From a long-term perspective, the stainless steel outer wire three-way pipe fittings water pipe is not higher than the plastic pipe. In addition, the aging problem of plastic water pipes is determined by its physical characteristics and cannot be changed. Sunlight, temperature, chemical substances, mechanical factors and time will accelerate the aging of plastic water pipes. After the plastic pipes are aged, they will burst under the impact of water pressure. It will greatly reduce the service life, and the use of hot-melt maintenance will deteriorate the material of the connection.
