Double Pipe High Pin Heat Exchanger

The hairpin heat exchanger is a U-tube heat exchanger with separate shells for both tube bundles (straight part of the tubes).Independent tubesheets for high-temperature differences, thermal shock and cycling. Moveable support brackets with slots for shell expansion and flexibility in installation.The reversal chamber over the U-tube bends can be welded or flanged.

vortex hot film heat exchanger membrane vortex hot film heat transfer using the

 latest technology, to increase the heat transfer effect by changing the fluid motion

 state, when the medium through the vortex tube surface, powerful flush the pipe

 surface, thus improve the thermal efficiency. Up to 10000 °C w/m2 .

At the same time the structure to achieve the corrosion resistance, resistance to

high temperature, high pressure, anti scaling function. Other types of heat exchanger

fluid channel as fixed direction flow form, formed on the surface of heat exchange

tube flow around, convective heat transfer coefficient decrease.

Characteristic：

• Reliable Closures for design pressures up to 15,000 psi (1055 kg/cm2)

• Independent tubesheets for high-temperature differences, thermal shock and cycling.

• External Split Rings do not contact Shellside fluid.

• All connections on the same end for ease of piping.

• Moveable Support Brackets with slots for shell expansion and flexibility in installation.
