The stainless steel tube has a long service life. From the analysis of the use of stainless steel abroad, the service life of stainless steel water pipes can reach 100 years, at least 70 years, which is the same as the service life of buildings. The service life of the composite pipe is affected and limited by the service life and thermal expansion of the main material. Since the composite pipe is a combination of two materials, the possibility of the bonding layer falling off is very high, which also affects the service life.
The service life of plastic pipes is difficult to determine in my country. It depends largely on the production process and the quality of raw materials. The quality is not uniform. The service life of plastic pipes can reach 50 years, but the direction of laying of water pipes must be completed by hot melt connection, and the joints are heated Melting effects, its physical structure is damaged, which is why almost everyone around us has experienced a water main leak. The service life of damaged water pipes is greatly reduced, and can only be used for 15-20 years, and the right to use the house is 70 years. The stainless steel pipe can reach the same age as the pipeline construction, that is, how long the water pipe can be used in the life of the building, which means that the average service life of the stainless steel pipe should exceed the service life of the house. So from this point of view, stainless steel pipes are not as expensive as plastic pipes.
The aging problem of plastic pipes is more prominent, sunlight, temperature, chemical substances, and mechanical factors. Time will cause its aging, the aging plastic is prone to explosion under the influence of water pressure and water hammer, and the service life is greatly reduced. In addition, the hot melt connection method is prone to water leakage or material deterioration at the connection.
Of course, buying stainless steel pipes is mainly for health reasons. The health value of improving the water environment to oneself and older children is immeasurable.
