China Suppliers Factory Rolling Bundy Tube Copper Pipe for Fridge & Air Conditioner Coiling
Character
The main features of Bundy tubes include high precision, high strength, good processing performance, and corrosion resistance. Bundy tubes are made by rolling, welding, and galvanizing cold-rolled steel sheets. Their double-layer structure and special manufacturing process give them unique advantages:
Bundy tubes use high-precision cold-rolled high-quality low-carbon steel strips and exquisite precision rolling technology to ensure the precision of pipe outer diameter and wall thickness, as well as good concentricity.
Bundy tubes have high explosive strength, high anti vibration fatigue limit, and can work stably in high-pressure and vibration environments.
Bundy tubes are easy to bend, weld, and process with various shapes of pipe ends, suitable for various complex processing needs.
lubricating oil with low carbon content is used in the manufacturing process to make the internal surface extremely clean, and the residue on the internal surface is less than 0.05g/m³.
The surface of Bundy tubes can be galvanized or coated with other anti-corrosion materials, such as PVF, aluminum rich coating (GALFAN pipes), nylon, etc., to further enhance their corrosion resistance.
