High Temperature Tube
Product Details
The GH3030 alloy pipe is a high-performance seamless pipe designed for extreme high-temperature applications. Made from a high-temperature alloy known for its excellent resistance to oxidation, corrosion, and high-pressure conditions, GH3030 alloy is widely used in various energy and industrial fields. Its advanced properties make it essential for high-parameter ultra-supercritical power generation boilers, gas turbines, and nuclear power facilities. The GH3030 alloy pipe is particularly beneficial in industries requiring materials that can endure harsh environments like gas-fired power generation, coal gasification, and oil and gas extraction.
High-Temperature Resistance:
GH3030 alloy pipes are engineered to perform in high-temperature conditions, making them ideal for power plants, turbines, and boilers.
Corrosion and Oxidation Resistance:
The alloy composition provides excellent resistance to both high-temperature oxidation and corrosion, especially in steam and flue gas environments.
Creep Resistance:
GH3030 pipes are designed to resist deformation under sustained high-temperature conditions, a key property for power generation and high-stress applications.
Excellent Durability:
Withstanding thermal and mechanical stresses, GH3030 alloy pipes provide long service life even in the harshest industrial environments.
Customizable Sizes:
Available in custom sizes with an outer diameter of 63mm, the alloy pipe can be tailored to meet specific application needs, ensuring flexibility and adaptability.
Energy and Power Generation:
Used extensively in ultra-supercritical power generation boilers, superheaters, re-superheaters, and gas turbines, where they are exposed to high temperatures, pressures, and corrosive environments.
Coal Gasification:
The pipes are also employed in coal gasification systems, which demand high-temperature corrosion and abrasion resistance.
Oil and Gas Industry:
Suitable for deep-well extraction where drilling tools encounter high temperatures, acidic conditions, and abrasive environments. GH3030 alloy pipes are resistant to corrosion caused by CO2, H2S, and mud.
Nuclear Power:
GH3030 pipes are used in nuclear power plants, specifically in steam generator heat transfer tubes, for their resistance to solution corrosion and high-temperature stability.
Chemical and Petrochemical Industries:
These pipes are crucial in chemical production and desalination plants, where resistance to high-temperature thermal corrosion is necessary.
Melting:
High-purity raw materials are melted in an electric arc furnace or induction furnace, followed by refining to achieve the desired chemical composition.
Casting:
The refined alloy is cast into ingots, which undergo heat treatment to ensure uniformity.
Forging:
The ingots are hot-forged at temperatures above 1100°C to enhance mechanical properties and achieve the desired shape.
Hot Rolling:
After forging, the material is hot-rolled to reduce thickness and achieve the final dimensions of the pipes.
Annealing:
The rolled pipes are annealed at temperatures around 900-950°C to relieve internal stresses and improve ductility.
Finishing:
The pipes are cut to the required lengths, and surface treatments such as grinding, polishing, or coating are applied for protection.
