The thin wall stainless steel pipe needs to follow some principles: namely, safety and reliability, economy, health, energy saving, sustainable development, several characteristics of which is environmental protection pipe, only to meet these standards can be regarded as qualified products.
The tensile strength of 304 stainless steel tubes is 2 times that of steel tubes, 3-4 times that of copper tubes and 8-10 times of plastic pipes. The strength of the material determines the quality of the pipe. And quality is often what customers need most. In the case of external impact, stainless steel pipe problems are few, but the probability of copper and plastic pipe problems are relatively high, the pipeline is easier to be damaged by construction or two renovation. Domestic complaints about plastic pipes are mainly water leakage, and the emphasis is on tensile properties.
The working pressure of high-rise water supply system is generally greater than 0.6Mpa; the pressure requirement of the pipe is higher. Plastic pipe for water supply system working pressure is less than this value, not equal to two; composite pipe thermal expansion coefficient difference, such as adhesion is not strong or large temperature changes caused separation; pressure thin copper pipe up to 5.9Mpa; and the thin wall stainless steel pipe with excellent mechanical properties, can withstand high water pressure. Can reach more than 10Mpa, especially suitable for building water supply.
