Incoloy 800

Incoloy 800 Nickel Alloy contains 15%-25% Chromium, 30%-45% nickel, and a small amount of aluminum and titanium. Type Incoloy 800 remains austenite single zone from being subjected to high temperature to rapid cooling, hence its use state keeps single austenite structure. The high chromium and sufficient nickel content contained within give it high temperature corrosion resistance and wide industrial application. Incoloy 800 alloy also features excellent resistance to stress corrosion cracking in chloride, low-concentration NaOH aqueous solution and high-temperature and high-pressure water, therefore it is used to manufacture equipment resistant to stress corrosion cracking.

Alloy 800 is used in high-temperature service applications where resistance is required from the effects of high-temperature corrosion such as oxidation and carburization.Typical applications include power generation, heat-treatment furnaces and hydrocarbon processing plants. With good creep and stress rupture properties, the material retains good metallurgical stability at high temperature. Alloy 800 is metallurgically stable in long-term applications at high temperatures. With excellent high-temperature strength, the alloy offers oxidation, carburization and sulfidation resistance.

Pipes are hollow cylindrical tubes that have been utilized by mankind for thousands of years for different purposes. Pipes can be produced from almost every material, however, since the modern-day meaning of pipes requires more than only being hollow tubes that transport fluid, metals have become more popular in pipe production. As a metal alloy, steels offer a great variety of mechanical and chemical properties that can be utilized under even extreme applications, therefore today, steel pipes have been utilized in many different applications for transportation manufactural and structural purposes. Steel pipes may be produced with different grades of steel with different production methods which vary due to application requirements.

Welded steel pipes—the ones with a seam—are used differently than seamless steel pipes. Seamless pipes are typically more lightweight and have thinner walls, and they’re used to make things like bicycles and liquid transportation pipes. Welded or seamed pipes, on the other hand, are heavier and better for transporting gas, electrical conduit and plumbing.

The main raw material used in steel pipe production is steel, which is made up primarily of iron. However, steel pipe commonly includes other elements such as aluminum, manganese, titanium, tungsten, vanadium and zirconium. Similarly, finishing materials are sometimes applied to help protect the pipe. Steel pipes come in a wide range of shapes and styles. The diameter of a steel pipe can range from a tiny tube used to make hypodermic needles to large pipes used to transport gas throughout a city. They can be short or long, have a thick wall or a thin one, and can be finished with varying coating materials. Often, steel pipes are manufactured for an intended purpose, and their characteristics are modified during production to better fit their task.

Incoloy 800 Tube is a nickel-chromium alloy that contains substantial amounts of iron, chromium, and nickel. It’s an ideal solution for high-temperature applications due to its excellent resistance to carburization, oxidation, and nitriding atmospheres. With a nominal composition of 36% Ni, 21% Cr and 0.7% C, this material provides superior corrosion resistance in many media, including up to 10% sulfuric acid environments. Combining these elements gives it good strength properties over a wide range of temperatures from cryogenic up to 1125°F (593°C). In addition, Incoloy 800 Tubing also exhibits good creep and rupture strength. This makes it ideally suited for the petrochemical and nuclear industries and other industrial applications such as heat exchangers, condensers, evaporators etc.

The Incoloy 800 tube has high structural strength and can withstand temperatures up to 1100°C. It offers excellent resistance to oxidation, carburization, and nitridation, which makes it a popular choice for high-temperature applications. Moreover, Incoloy 800 tubing has an excellent resistance to corrosion, both in acidic and alkaline environments. This property makes it ideal for use in chemical and petrochemical industries. Incoloy 800 tube is a nickel-iron-chromium alloy that combines excellent tensile strength, creep rupture strength, and corrosion resistance in oxidizing and reducing atmospheres.

It has good formability, weldability and traceability characteristics. The alloy is especially suitable for high-temperature environments because of its outstanding mechanical properties and excellent resistance to carburization and oxidation at elevated temperatures up to 1150°C (2102°F). Its outstanding features include high ductility, good fabricability and long-term service life even when exposed to corrosive environments such as sulphuric acid or phosphoric acid solutions. In addition, Incoloy 800 possesses great stability under gradual thermal cycling in extreme conditions of temperatures ranging from -200°C (-328°F) all the way up to 1000°C (1832 °F).

Incoloy 800 tube is also known for its formability and weldability. It can be easily shape into numerous shapes and sizes without compromising its strength and durability. It can be easily welded and join with other components, making fabricating easier in different applications. Its exceptional properties make it an excellent material choice for industries that require high-performance and reliable alloys.

Incoloy 800 Pipe is produced using advanced manufacturing processes such as hot working, cold working, and annealing. The piping can be fabricated using conventional welding, brazing, and soldering techniques. Incoloy 800 Pipe is available in different sizes, shapes, and thicknesses to suit various industrial and commercial applications.Incoloy 800 Pipe requires regular maintenance to ensure optimal performance and longevity. It should be cleaned regularly using appropriate cleaning agents and techniques to remove corrosive materials. Also, proper piping handling and storage should be observed to prevent damage.

Application of Incoloy 800 pipes

Structural Usage

Structural use is commonly building and construction in which the building material is commonly referred to as steel tubes. Steel tubes are used to provide additional strength and stability for especially high buildings or constructions. Two types of steel pipes are utilized in structural usage as end-bearing piles and friction piles that both have the aim of transferring the load of the building. In those applications, steel pipes are driven deep into the earth before the foundation is laid, which constitutes great support to the building especially when the ground is not secure. Another structural application of steel pipes is scaffolding poles which allow construction workers to access all areas of the building that are out of reach. They are made by linking steel tubes into each other as a cage that surrounds the building.

Manufacturing Usage

Steel pipes are being utilized for many different purposes in manufacturing use. Guard rails are one of the most common usages to provide a safety feature for stairs and balconies, or, in street, for cyclists and pedestrians. Steel pipes can also be utilized as security bollards which are used to cordon off an area from vehicle traffic to protect people, buildings, or infrastructures. Also, steel pipes constitute an option for outdoor site furnishings. Many commercial bike racks are formed by bending steel tubes. High toughness and strength of steel make it secure against thieves.

Transportation Usage

The most common usage of steel pipes is the transportation of products since the characteristics of the raw material is very suitable for long-term installations. As it has mentioned before, different applications require different properties, as for low-pressure applications it is not expected for a steel pipe to exhibit ultra-high-strength since it does not expose to significant loading. More specialized applications to be used in the oil and gas industry may require more stringent specifications due to the hazardous nature of the product and the possibility of increasing pressure. These requirements bring a higher cost and quality control becomes more critical.
