The thickened socket copper elbow developed for the steering needs of refrigeration system pipelines is made of high-purity copper, which not only ensures excellent thermal conductivity to quickly respond to temperature changes in the refrigeration system, but also has outstanding chemical stability and does not react with refrigerants (such as R32, R410A, etc.) in the refrigeration system. The pipe fitting has uniform thickened wall thickness, processed by CNC lathe with wall thickness deviation controlled within ±0.05mm. The socket depth is scientifically designed according to the pipe specification, 2-3mm deeper than the ordinary socket. During welding, a deeper fusion zone can be formed to ensure firm connection and effectively prevent refrigeration medium leakage. It provides a precise 45° angle, adapting to different pipeline direction designs, and can flexibly cope with horizontal steering, vertical steering or inclined steering; the flared part is finely processed through mul…
