Copper strip around carbon steel tube KL type finned tube

KL-wound finned tube: Before the fin is continuously wound on the surface of the steel pipe, the outer surface of the base tube needs to be knurled; after the fin is wound, the root of the fin attached to the steel pipe will also be knurled to strengthen the steel pipe and Combination of fins. This fin type ensures better heat transfer characteristics than L and LL fins. Working temperature: 250℃

Vacuum heat exchange tube finned tube

The vacuum finned tube waste heat boiler forms a finned tube by winding fins on the existing smooth tube, which increases the heat exchange area, thereby improving the thermal efficiency. In addition, the utility model is compact in structure, small in size, less material, and non-explosive tube , High safety, and can be suitable for occasions from low temperature to high temperature, from low pressure to high pressure.

Elbow finned tube for custom heat exchanger

After the two edges of the finned tube and the steel tube to be welded are heated to the welding temperature under compressive force, welding is performed; therefore, the welding pressure on the finned tube significantly affects weld quality. If the welding pressure is too high, the molten metal from the finned tube will be entirely squeezed out of the weld zone, resulting in poor welds and, in severe cases, causing fin buckling and compromising the finned tube’s shape and dimensions. Conversely, if the welding pressure is too low, oxides and inclusions in the weld zone cannot be adequately expelled, leading to slag inclusions and defective welds.

U-shaped stainless steel finned tube elbow

U‑shaped bends, also known as elbows, are a type of pipe fitting. They are further classified into cold‑bent and hot‑bent types. For small and medium‑diameter pipes, cold bending is typically used; larger diameters generally require hot bending. These fittings are primarily employed for bending nonferrous and ferrous metal tubing and are suitable for applications in construction materials, shipbuilding, chemical processing, metallurgy, boiler manufacturing, and heavy machinery production. Our products are widely utilized in architectural curved steel structures, tunnel supports, roof‑mounted curved beams, subway projects, aluminum doors and windows, ceiling systems, internal column‑encasing frameworks, balcony handrails, shower enclosure doors, production line tracks, fitness equipment, and many other industries. Available materials include carbon steel, alloy steel, stainless steel, copper, aluminum, and more.

Copper and aluminum composite U-shaped finned tube

Copper finned-tube heat exchangers are widely used in residential, commercial, and industrial refrigeration and air-conditioning systems. Their excellent thermal‑transfer performance is essential for maintaining the high efficiency of these systems. Typically, copper finned tubes exhibit high heat‑transfer efficiency during the initial stages of operation; however, after a period of use, their cooling and heating capacities decline, indicating a deterioration in the long-term heat‑transfer performance of the finned‑tube heat exchanger.

U-shaped finned tube elbow

Our company supplies S-shaped finned tubes and U-shaped finned tubes, copper-aluminum composite U-shaped tubes, steel-aluminum composite U-shaped tubes, copper-copper composite U-shaped tubes, and various specifications of composite finned tubes. Our company has its own bending For pipe machines, buyers can choose the size of the elbow according to their needs.

Slotted finned tube-aluminum strip embedded in carbon steel tube

Inlaid G-shaped finned tube-aluminum tape wound copper tube

Classification and Concept of G‑Type Finned Tubes: To enhance heat transfer efficiency, fins are typically added to the surface of heat exchange tubes. G‑type finned tubes increase the total surface area (or internal surface area) of the tube, thereby improving heat transfer performance. Such heat exchange tubes are referred to as G‑type finned tubes. Based on their shape and structure, G‑type finned tubes can be categorized into square finned tubes, helical finned tubes, longitudinal finned tubes, helical serrated finned tubes, and internally finned tubes.
