GB5310 2017 High Pressure Boiler Tube
1. Overview. GB5310-2017 high-pressure boiler tube is a metal tube widely used in petroleum, chemical, electric power, machinery manufacturing and other industries, with high strength, high pressure resistance, high thermal conductivity, low expansion coefficient and other excellent properties. The high-pressure boiler tubes of this standard are made of high-quality carbon steel, alloy steel and other materials, and can meet the requirements of various complex environments in accordance with the specified technical requirements. This article will focus on the characteristics, production process, application fields and future development direction of GB5310-2017 high-pressure boiler tube.
Second, the characteristics of high-pressure boiler tubes.
GB5310-2017 high-pressure boiler tubes have the following characteristics:
1.High strength: Made of high-quality carbon steel, alloy steel and other materials, it has high tensile strength and yield strength, and can withstand loads in various complex environments.
2.High pressure resistance: It has good pressure resistance, can work stably for a long time in high temperature and high pressure environment, and is suitable for the manufacture of high-pressure vessels, pipelines and other equipment in the fields of petroleum, chemical industry, electric power, etc.
3.High thermal conductivity: It has good thermal conductivity, which can effectively transfer heat, reduce thermal resistance, and improve the thermal efficiency of equipment.
4.Low coefficient of expansion: The special production process is used to make the thermal expansion coefficient of the high-pressure boiler tube low, which can effectively reduce the deformation and stress caused by temperature changes, and improve the stability and reliability of the equipment.
3. Production process of high-pressure boiler tubes.
The production process of GB5310-2017 high-pressure boiler tube mainly includes the following steps:
1.Smelting: The raw material is melted into molten steel by smelting methods such as electric furnace, open-hearth furnace or converter, and the necessary alloying treatment is carried out to ensure that the chemical composition of the molten steel meets the requirements of the standard.
2.Continuous casting: Qualified molten steel is injected into the continuous caster, and after cooling and solidification, a certain specification of steel billet is formed.
3.Rolling: The continuously cast billet is heated and rolled, gradually reducing the diameter and thickness of the billet until the desired billet size is reached.
