Description:

DIN2391 4 6 8mm Air Conditioning Steel Tube for Fluid Handling System

Introduction

The DIN2391 4 6 8mm air conditioning steel tube is a high-quality solution designed for fluid handling systems in air conditioning applications. Built to meet DIN2391 standards, these steel tubes offer exceptional durability, precision, and reliability, making them ideal for use in demanding fluid handling environments.

DIN2391 Standard Overview

DIN2391 is a standard specification for seamless precision steel tubes, specifically designed for use in hydraulic and pneumatic systems, as well as in automotive and mechanical engineering applications. It sets strict requirements for dimensions, tolerances, mechanical properties, and surface quality, ensuring consistent performance and compatibility with fluid handling systems.

Specifications of Air Conditioning Steel Tube

The air conditioning steel tube available in 4, 6, and 8mm diameters conforms to DIN2391 standards and is manufactured using precision cold drawing processes. These tubes are made from high-quality steel grades with excellent corrosion resistance and mechanical properties, ensuring optimal performance and longevity in air conditioning fluid handling systems.

Precision Cold Drawing Process

The air conditioning steel tube undergoes a precision cold drawing process to achieve its final dimensions and mechanical properties. During cold drawing, the steel tube is pulled through a series of dies at room temperature, resulting in improved dimensional accuracy, surface finish, and mechanical strength. This process ensures tight tolerances and uniformity across the length of the tube, essential for fluid handling applications.


Features:


Precise sizing: The DIN2391 standard strictly regulates the three outer diameter sizes of 4mm, 6mm and 8mm, ensuring a high degree of adaptability during installation and connection of the steel pipe, and reducing system failures due to dimensional deviations.

Excellent pressure resistance: Made of high-quality steel, it can withstand the pressure changes of the fluid in the air conditioning system, ensuring the stability and safety of the system in long-term operation.

Excellent corrosion resistance: After special treatment, it can effectively resist the chemical attack that may exist in the air conditioning system, and prolong the service life of the steel pipe.

Low coefficient of friction inner wall: The smooth inner wall of the steel pipe reduces the resistance of the fluid to flow, thereby reducing energy loss and improving the overall energy efficiency of the system.

Applications in Air Conditioning Systems

  • Refrigerant Circulation: Used for conveying refrigerants such as R-410A, R-134a, and R-22 in air conditioning systems.

  • Coolant Transfer: Facilitates the transfer of coolant fluids between different components of the air conditioning system, such as evaporators, condensers, and compressors.

  • Pressure Regulation: Provides a reliable conduit for maintaining optimal pressure levels within the air conditioning system, ensuring efficient operation and performance.


Conclusion: 

DIN2391 4 6 8mm air conditioning fluid handling steel pipes play a key role in air conditioning fluid handling systems due to their precise dimensions, excellent compressive and corrosion resistance, and efficient fluid transfer capabilities. Its wide range of applications not only improves the performance and reliability of the air conditioning system, but also brings users a more comfortable and energy-saving experience.
