GLL Metal bellow for heat exchanger

Product Description:

GLL type metal corrugated tube heat exchanger is a high-efficiency heat exchange equipment that uses corrugated tubes as heat exchange elements. Compared with traditional smooth straight tubes, the structure of corrugated tubes can undergo periodic changes, causing sufficient disturbance to the fluid in the tube, causing the fluid to appear in a turbulent state, thereby significantly enhancing heat transfer capability

Main features:

Efficient heat transfer: The structure of the bellows causes the fluid to be disturbed during the flow process, reducing the thickness of the boundary layer and improving heat transfer efficiency.

Self-compensation ability: The continuous contraction and expansion of the corrugated tube has a certain degree of compensation ability. It can expand and contract freely under stress to avoid damage to components such as the heat exchanger tube plate.

Anti-scaling performance: The slight telescopic movement of the bellows makes it anti-fouling, reducing the possibility of scaling and reducing maintenance costs.

Strong adaptability: The corrugated tube heat exchanger can withstand medium and low pressures, has strong corrosion resistance, has a long service life, and can adapt to large temperature differences.

GLL type metal corrugated tube heat exchanger is widely used in chemical industry, machinery, electrical engineering, textile, papermaking, mining and other industries, and is suitable for liquid-liquid heat transfer and external condensation in the tube.

GLL bellows heat exchanger is a new type of shell-and-tube heat exchanger. Its main feature is the use of a bellows structure in the heat exchange tube part. Compared with traditional smooth straight tubes, the structure of corrugated tubes changes periodically, which fully disturbs the fluid in the tube and forces the fluid to flow turbulently, thus enhancing the heat transfer capability. 

The appearance of the bellows heat exchanger is similar to that of an ordinary heat exchanger, and the shell side adopts an ordinary cylindrical structure. Its biggest feature is that the tube side adopts thin-walled corrugated heat exchange tubes. The tubes are processed by a corrugator to form bulges on the walls of the heat exchange tubes, and are strength welded to the tube plates through the pipe sleeves welded to them.

The structure of the corrugated tube heat exchanger can be divided into four structural types: fixed tube plate type, floating head type, kettle type and U-shaped tube type according to the form of tube plate, shell and matching parts. These structural types are roughly the same as traditional shell and tube heat exchangers, except that the main internal heat transfer elements use corrugated heat exchange tubes.
