The double-pipe heat exchanger is made of concentric casing made of straight pipes with different diameters and connected by u-shaped elbows.  

● In this kind of heat exchanger, one kind of fluid goes through the tube, the other kind of fluid goes through the ring gap, both can get higher flow rate, so the heat transfer coefficient is larger.  

● In the double -pipe heat exchanger, the two fluids can be pure countercurrent, the logarithmic average force is larger 

Application

Oil refining, petrochemical , natural gas chemical, coal chemical, shale oil , syntheticresin and plastic, rubber, chemical fiber, chemical, pharmaceutical, daily chemical, chemical additives , metallurgical , power , light, food and other industries of material preheating, heating, cooling, distillation, distillation, concentration, material and the heat back Collection, tail gas treatment and other processes industrial.

Advantage

Simple structure, convenient application

high pressure resistance, large heat transfer coefficient.

The heat transfer area can be adjusted as required.
