1, Stainless steel flexible tubes of the bellows from the chrome-nickel austenitic stainless steel, used to guard against pitting and nitrogen ions in dilute sulfuric acid, dilute sulfuric acid corrosion damage.
　　2, the user equipment with stainless steel hose, piping systems for pressure experiments, the impact should be to prevent rust block, chlorine ion sediment deposition, resulting in corrosion and mechanical damage.
　　3, when the metal hose to be installed to prevent welding spatter burns and mechanical damage, otherwise it will cause leaks.
　　4, sealing piping should strictly comply with safety rules to prevent improper operation or other factors caused by excess pressure caused the hose pull-off or burst.
　　5, carefully digested stainless steel flexible tubes for example installation methods, and in strict accordance with the correct thumbnail installation.
