Stainless nickel and alloy piping is the latest alloy pipe, which is made of nickel, iron, chromium, copper, aluminum and other elements added in proportion. It has excellent pressure resistance, wear resistance, corrosion resistance, high temperature strength and oxidation resistance. Its excellent welding and processing performance is very convenient for processing and producing various complex pipeline systems.
- Excellent corrosion resistance: Stable performance, resistance to various strong acid and alkali environments, good stability
- Strong tolerance to high temperature: Maintain good mechanical properties under high pressure and high temperature distillation, high temperature chemical reaction and other process conditions, with high melting point and creep strength.
- These pipes have Good mechanical properties, various metal processing equipment in the factory can be processed and produced normally into pipeline equipment and mechanical equipment
- Applied to the chemical industry, commonly used for conveying acidic and alkaline media such as sulfuric acid, nitric acid, and hydrochloric acid
- Applied to new environmental protection equipment and environmental protection projects, sewage treatment equipment, waste gas purification equipment and other environmental protection fields
- Used in energy, minerals and deep processing industries, such as oil pipelines, natural gas pipelines, petrochemical equipment
4.Used in other special industries such as aerospace, automobiles, precision instruments, etc.
