Tube Bundled Heat Exchangers :
In the gas pressure reduction process by the “Joule-Thomson” effect, temperature drops considerably (about 0.5°C per reduction bar are estimated ).
This fall in gas temperature can damage equipment due to formation of dangerous ice crystals produced by water vapor in the gas.
In first stage stations in particular, gas must be heated before pressure is reduced, since high pressure changes are usually involved.
We recommend that, after reduction, gas temperature should not be below 5°C. One of the best established methods of heating gas in reduction stations is to use heat exchangers employing hot water or steam as their thermal carrier fluid.
The tube bundle heat exchangers we produce are sized and designed to meet a very wide range of system requirements, and include all connections for accessories
TUBE BUNDLED HEAT EXCHANGERS DESIGN AND FUNCTION
- The heat exchangers consist basically of housing and tube bundle.
- The housing is a welded construction and includes all connecting, joining and fastening elements.
- The standard smooth tube bundle to be installed is a two-way model.
- The exchanger design variation with U-tubes (U-design), the variation with the floating tube base (D-design) or with a fix compensator (K-design) all of them allow for large changes in length between the casing and the tube bundle due to heat expansion.
