Industrial Steel Heat Pipe Heat Exchanger Shell And Tube Manufacturers
Description
Shell and tube heat exchanger is mainly composed of shell, tube bundle, tube plate and sealing head. The shell is round and equipped with parallel tube bundle or spiral tube inside. The two ends of the tube bundle are fixed on the tube plate. In the tube heat exchanger for heat exchange in the two fluids, a flow in the tube, the stroke is called the tube; One flows outside the tube and its stroke is called shell side. The wall of the tube bundle is the heat transfer surface. The types of pipes are different, the process is generally three models with diameter of 16mm, 20mm or 25mm, and the thickness of pipe wall is generally 1mm, 1.5mm, 2mm and 2.5mm. Most materials are 304 or 316L.

advantage:
(1) It has both heat exchange and heat storage functions. The upper part of the heat exchange tube bundle of the shell and tube heat exchanger is the heat storage part, which belongs to the same temperature hot water area. volume to adapt to changes in water load; the outlet water temperature is stable, and the water supply is safe and reliable.
(2) The resistance loss of the heated water through the tank is very small. When the cold water passes through the shell and tube heat exchanger, the cross section of the water is very large, the flow velocity is less than 0.01m/s, and the resistance loss is very small, generally only 0.1~0.2m, which is extremely beneficial for maintaining the pressure balance of the cold and hot water supply at the water point. .
(3) The requirements for heat medium are not strict. The shell-and-tube heat exchanger has a large heat storage capacity, and its heating load can be calculated according to the size of the heat consumption, which can reduce the boiler and pipe network load by half, greatly saving the investment in the heating medium supply system, and at the same time heating coal. The use of the boiler is relatively uniform, which is conducive to improving the thermal efficiency of the boiler and prolonging its service life.
(4) The structure is simple, the management is convenient, it can withstand water pressure, and the noise is low.
