Description
Product Overview: GB/T24187-2009 sets forth the detailed technical criteria for Cold Drawn Welded Refrigerator Tubes. These tubes are specifically designed to conform to the exacting standards of refrigeration applications, guaranteeing superior performance and dependability. The process of cold drawing and welding contributes to the tube's robust structural strength, establishing it as the preferred option for use in refrigeration systems.
Key Features:
High-quality materials: These refrigerator tubes are manufactured with high-quality materials, which ensures their long-term stability and reliability in the refrigeration system.
Precise size: The cold drawing process makes the pipe with high dimensional accuracy and uniform inner and outer diameter, which meets the strict requirements of the refrigeration system for the size of the pipe.
High strength: Through the cold drawing and welding process, the structural strength of the pipe is enhanced, which can withstand the pressure and mechanical load in the refrigeration system.
Corrosion resistance: The surface of the refrigerator tube has been specially treated, which has good corrosion resistance and is suitable for a variety of refrigerant environments.
Cleanliness: The cleanliness of the pipes is strictly controlled during the manufacturing process, which reduces internal pollution and ensures the purity of the refrigerant.
Welding quality: The welding process is carried out in strict accordance with the standard to ensure the quality of the welded part and avoid the risk of leakage and fracture.
Flexibility: Cold-drawn welded refrigerator tubes have good bendability, which is easy to install and layout in the refrigeration system.
Economy: Compared with seamless steel pipes, cold-drawn welded pipes offer cost advantages while maintaining high performance.
Standardization: The GB/T24187-2009 standard provides clear technical specifications for the production and inspection of pipes, ensuring the uniformity and interchangeability of products.
Applications:
These refrigerator tubes are designed for use in various refrigeration systems, including domestic and commercial appliances, air conditioning units, and industrial refrigeration equipment. Their precision and reliability make them a preferred choice for manufacturers and engineers in the refrigeration industry.
