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.


Product Features

  • Precise Dimensional Compliance
    Strictly manufactured to DIN 2391 standards with standardized outer diameters (4mm, 6mm, 8mm), ensuring perfect compatibility with system components. This dimensional precision facilitates easy installation and eliminates potential leaks caused by sizing mismatches.

  • Exceptional Pressure Resistance
    Constructed from high-grade steel, the tube maintains structural integrity under significant pressure fluctuations within HVAC systems. This guarantees long-term operational stability and safety under continuous working conditions.

  • Enhanced Corrosion Resistance
    Specially treated surfaces provide superior resistance to chemical corrosion from refrigerants and environmental factors, significantly extending the service life of the tubing in demanding applications.

  • Optimized Flow Efficiency
    The smooth internal surface minimizes fluid flow resistance, reducing energy consumption and enhancing the overall efficiency of the air conditioning system.

  • Reliable Seamless Construction
    Seamless manufacturing technique ensures uniform wall thickness and eliminates potential weak points, providing consistent performance throughout the system's lifecycle.

Typical Applications in HVAC Systems

  • Refrigerant Circulation Lines
    Ideal for conveying modern refrigerants including R-410A, R-134a, and R-22 with maximum reliability and minimal permeability.

  • Coolant Transfer Conduits
    Efficiently transports coolant between critical system components such as compressors, condensers, and evaporators.

  • High-Pressure Fluid Containment
    Provides a secure pathway for maintaining system pressure integrity, ensuring optimal operating conditions for all HVAC components.

  • Heat Exchange System Connections
    Suitable for connecting various elements in heat exchange systems where precise dimensions and leak-proof performance are essential.

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.
