Heat-resistant steel centrifugally cast tube is a special type of steel tube designed and produced to withstand the pressure and working conditions of high-temperature environments. This type of steel tube is widely used in petroleum, chemical, electric power and thermal industries, especially where high-temperature fluids or gases need to be handled.

The main material of heat-resistant steel centrifugal cast tube is alloy steel, which is a type of steel that can maintain high strength and good chemical stability at high temperatures. Alloy steel is usually composed of iron, carbon, chromium, nickel, tungsten and other elements, among which chromium and nickel are the key elements to improve the heat resistance of steel. Chromium increases steel's resistance to oxidation, while nickel improves steel's toughness and strength.

What is the production process?

  ● Raw material preparation: Select high-quality heat-resistant steel raw materials and perform necessary preprocessing, such as crushing, screening, mixing, etc.

  ● Melting: The raw materials are melted in a high-temperature furnace to form molten steel.

  ● Centrifugal casting: The molten steel is poured into a centrifugal casting machine, and the molten steel is formed into a tube shape under the action of centrifugal force through high-speed rotation. During this process, the inner and outer walls of the steel tube will be formed at the same time, and the formed steel tube will gradually cool and solidify.

  ● Heat treatment: Heat treatment is performed on the cast steel tube to improve the stability of its structure and performance.

  ● Finishing treatment: Cutting, grinding, testing and other finishing treatments are carried out on the steel tube to ensure that the quality and size of the steel tube meet the requirements.

What are the characteristics of heat-resistant steel centrifugal cast tubes?

  ● Due to the use of special heat-resistant steel, this steel tube can maintain good strength and stability at high temperatures and is not easily deformed or damaged.

  ● The inner and outer walls of the steel tube are very smooth and are not prone to leakage, ensuring the safe transmission of fluids.

  ● It has high strength and toughness and can withstand greater pressure and impact.

  ● The material of the steel tube has good corrosion resistance and can be used for a long time in harsh environments.

What are the main uses?

  ● In the field of petrochemical industry, it is used to transport high-temperature, high-pressure oil and gas and chemical raw materials, such as oil, natural gas, ethylene, etc.

  ● In the power industry, it is used to manufacture key components of boilers, steam turbines, generators and other equipment, such as superheaters, reheaters, steam tubes, etc.

  ● In the thermal industry, it is used to transport high-temperature steam and hot water, such as urban heating, industrial heat, etc.
