Inconel 686 Nickel Based tube
Inconel 686 Nickel Based tube is a high-performance nickel-chromium-molybdenum-tungsten alloy. It is designed for extreme corrosive environments. It is made by precision processing. It has excellent corrosion resistance, high-temperature strength and oxidation resistance. It is used in chemical, energy and marine engineering with harsh working conditions. It has a high content of molybdenum (15-17%) and chromium (19-23%) in its composition. This gives it excellent pitting and crevice corrosion resistance. Tungsten (3-4.4%) further improves its resistance to uniform corrosion.
Inconel 686 Nickel Based tube is widely used in chemical industry (reactors, heat exchangers), environmental protection (flue gas desulfurization systems), marine engineering (seawater desalination equipment, subsea pipelines) and energy fields (nuclear power, high-temperature parts of gas turbines). Its excellent corrosion resistance, high-temperature stability and mechanical strength make it an ideal material for extreme environments. It greatly improves the durability and safety of equipment.
Features of Inconel 686 Nickel Based tube
Excellent Corrosion Resistance: Inconel 686 Nickel Based tube performs well in acidic, chloride and oxidizing media. It is far better than ordinary stainless steel in sulfuric acid, hydrochloric acid and fluorine-containing environments.
High-Temperature Stability: Inconel 686 Nickel Based tube can keep strength below 1200°C. It has excellent oxidation and sulfidation resistance. It is suitable for high-temperature and high-pressure environments.
Strong Mechanical Properties: Inconel 686 Nickel Based tube has high tensile strength and fatigue life. It also has good weldability and formability. It is easy to process and install.
Adaptability to Various Environments: Inconel 686 Nickel Based tube is resistant to seawater corrosion and stress corrosion cracking (SCC). It is used in offshore platforms and the nuclear industry.
Applications of Inconel 686 Nickel Based tube
Chemical Industry: Inconel 686 Nickel Based tube is used in reactors and heat exchangers for sulfuric acid and phosphoric acid. It is also used in piping systems.
Environmental Field: Inconel 686 Nickel Based tube is used in scrubbers and chimney linings of flue gas desulfurization (FGD) equipment.
Marine Engineering: Inconel 686 Nickel Based tube is used in subsea pipelines, seawater desalination equipment and components in high-salinity environments.
Energy Field: Inconel 686 Nickel Based tube is used in nuclear power condensers, hot parts of gas turbines and high-temperature furnace tubes.
