Seamless carbon steel boiler tubes for high pressure

• ​Introduction

Seamless carbon steel boiler tubes are special pipes made of carbon steel, mainly used in boiler systems. They are designed to withstand high temperatures and high pressures, serving as key components to ensure the normal operation of boiler systems. They are widely used in steam boilers, power plants, fossil fuel factories, industrial processing plants, etc. Boiler tubes can be medium-pressure boiler tubes or high-pressure boiler tubes.

• ​Main Functions

Heat Exchange：They are used to transport high-temperature steam and hot water in boilers, and to achieve heat exchange in heat exchangers and condensers, thereby promoting efficient heat transfer.

Medium transportation: They transport working media such as water and steam in boilers and superheaters, enabling the smooth progress of the entire thermodynamic cycle.

Structural Stability：Withstand the high pressure generated inside the boiler, ensuring the safety and stability of the boiler system during operation.

Seamless carbon steel boiler tubes have high strength, including high tensile strength and yield strength, which can ensure the safety and reliability of the tubes under high – pressure conditions. They also have certain corrosion resistance and oxidation resistance, which can resist the erosion of high – temperature flue gas and water vapor to a certain extent, prolonging the service life of the tubes. In addition, they have good dimensional accuracy and surface quality to ensure the stability and tightness of the connection with other components in the boiler system.

• ​Manufacturing Process ​

Hot Rolling ​； Cold drawn/Rolling ​

Heat treatment: According to the performance requirements of the steel pipe, conduct heat treatment on the rolled steel pipe, such as normalizing, tempering, quenching, etc., to eliminate the residual stress inside the steel pipe and improve its strength, toughness, hardness, and other properties.

Inspection: Conduct a comprehensive inspection on the finished steel pipe, including the inspection of dimensional accuracy, appearance quality, mechanical properties, chemical composition, etc., to ensure that the steel pipe meets the relevant standards and customer requirements.
