Introduction to Boiler and Heat-Exchanger Tubes

In industrial applications, the efficiency and reliability of energy generation and thermal transfer systems are paramount. One of the critical components in these systems is the boiler and heat-exchanger tubes. These tubes are vital for maximizing energy efficiency and ensuring optimal performance in boilers, heat exchangers, heaters, and condensers.

This product introduction outlines the features, specifications, and industry standards associated with seamless stainless steel boiler and heat-exchanger tubes, underscoring their importance in various applications.

Product Description

Boiler and Heat-exchanger Tubes are manufactured using high-quality prime raw materials, ensuring exceptional durability and performance. Our tubes are cold drawn, resulting in a clean and smooth surface on both the outer diameter (OD) and inner diameter (ID). This meticulous manufacturing process allows our tubes to withstand high pressure without deformation, maintaining structural integrity under stress.

Key features include:

• High-Pressure Resistance: The tubes are designed to handle high-pressure environments, essential in applications like boilers and heat exchangers, where failure can lead to severe operational issues.
• Deformation Resistance: These tubes exhibit no deformation after cold bending, ensuring flexibility without compromising strength or shape.
• Durability: Our tubes do not crack or break during flattening and flaring processes, crucial for fitting and installation in complex systems.

These tubes find widespread application in energy generation and thermal management sectors, including but not limited to:

• Boilers: For steam generation and heating.
• Heat Exchangers: For efficient thermal transfer between fluids.
• Heaters and Condensers: For optimizing heat management within systems.

Delivery Condition

Our tubes are available in two primary delivery conditions:

• Bright Annealed (BA): This condition provides a smooth, reflective finish, enhancing corrosion resistance.
• Pickel Annealed (PA): A treatment that removes oxides from the surface, ensuring better adherence in subsequent applications.

The tube ends are supplied with a plain finish, allowing for easy integration into pipe systems.

Grades and Specifications

Our range of seamless stainless steel tubes includes various grades, each tailored for specific application demands. The following grades (UNS) are available:

• 304/304L/304H (1.4301/1.4306/1.4948): Commonly used for excellent corrosion resistance and high-temperature applications.
• 316/316L (1.4401/1.4404): Known for superior corrosion resistance in harsh environments, particularly in chemical processing.
• 316Ti (1.4571): Offers additional titanium stabilization, ideal for high-temperature applications.
• 321 (1.4541): A stabilized stainless steel that is excellent for high-temperature services.
• 309S (1.4833) & 310S (1.4845): High chromium and nickel content make these grades suitable for extreme heat.
• 317L (1.4438): Provides enhanced resistance to pitting and is suitable for high chloride environments.
• 2205 (1.4462) & S31803: These duplex stainless steels balance strength and corrosion resistance, making them ideal in petrochemical environments.

Industry Standards

To ensure our products meet the highest performance and safety standards, we adhere to various industry norms, including:

• EN 10216-5: Specifies the technical delivery conditions for seamless tubes made of stainless steel.
• DIN 17456 and DIN 17458: Standards related to the quality assurance of stainless steel tubes.
• GB/T14975; GB/T14976; GB/T13296; GB5310: Chinese standards that outline the specifications for various stainless steel tube applications.
• ASTM A213; A269; A312; A511; A789; A790: American standards governing seamless stainless steel tubes for high-temperature applications.
• JIS G3459; G3463: Japanese standards ensuring the quality and reliability of stainless steel pipe and tube products.
