China Welded flat-oval aluminum tubes Manufacturers, Suppliers, Factory

Rectangular tubes—precision-formed hollow metal sections with flat sides—play a central role in structural engineering, transportation equipment, fabrication, and industrial machinery. Their uniform geometry, high load-bearing capability, and compatibility with various joining methods have made them one of the most requested metal profiles across global markets.

​Precision D Shaped Condenser Aluminium Tubing, also commonly known as D-shaped aluminum flat tube, belongs to special-shaped precision extruded aluminum profiles. The cross-section of the pipe is a D-shaped structure, which is different from traditional round aluminum pipes. One side is straight and the other is a curved surface. With high-precision wall thickness control, it has the advantages of lightweight, excellent thermal conductivity, and stable fluid flow. With excellent heat transfer efficiency and compact structure, precision D-type condenser aluminum tubes are no longer limited to original refrigeration equipment, but have been widely used in building related projects such as HVAC, passive rooms, and building energy-saving systems. They are one of the core pipes for building energy-saving heat transfer systems.

​ Laser Welded Leak Proof Connection Heater Core Tubing, the core of which is the sealing welding of the internal flow channel tube and inlet and outlet joints of the heating core body (heater core), is mainly used in the automotive heating core body, and also expanded to the fields of new energy thermal management and industrial small heat exchangers:

Single chamber tubes for radiators typically refer to the type of tubes used in single tube radiators. These types of radiators have one tube that circulates hot water or steam throughout the system, and the heat is radiated out into the room.

​The B-Tubes for Folded Radiator plays a core role in carrying out the circulation and heat transfer of the core heat exchange medium, while adapting to the structural characteristics of the folding radiator, taking into account heat transfer efficiency, structural strength, and assembly adaptability. It is the core carrier for achieving heat dissipation function, and its specific function can be disassembled into the following key dimensions:

Commercial HVAC System Condenser Header Pipes​ are critical pressure components that distribute and collect refrigerant flow across condenser coil circuits. Poor header quality leads to refrigerant maldistribution, pressure drop rise, refrigerant leakage, compressor failure and costly site claims for global HVAC OEMs and system integrators.
