Fouling in Heat Exchangers - IntechOpen

sectional area of tubes or flow channels is reduced. In addition, increased surface roughness due to fouling will increase frictional resistance to flow. Such effects inevitably lead to an increase in the pressure drop across the heat exchanger, which is required to maintain the flow rate through the exchanger, and may even lead to flow blocks.

Tubes-The tubes are made of seamless drawn steel, a popular size being 3 1/4 inch outside diameter which is the way all boiler tubes are measured. When tubes are installed they are pushed in through the holes in the front head which are slightly larger than the outside of the tubes, and back through the water space and through the corresponding

Pressure Test: Hydrostatic and Pneumatic Test Requirements

Nov 02, 2011 · In case the MAWP of a boiler is 2, 000 kpa (20 bars), the needed test pressure is normally 2, 000 X 1. 5 = 3, 000 kPa (30 bars). Stop the pump operation at the test pressure in addition to close the ball cock within the pump. Wipe dry or spray with compressed air on the flanges and manholes to get rid of water residue.

Nitrate test - Wikipedia

A common nitrate test, known as the brown ring test can be performed by adding iron(II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution. A brown ring will form at the junction of the two layers, indicating the presence of the nitrate ion. Note that the presence of nitrite ions will interfere with this

Fouling and Fouling Mitigation on Heat Exchanger Surfaces

Apr 14, 2011 · Several studies [32-35] have shown that finned tubes foul less than plain tubes. Non-uniform thermal expansion leads to lower deposit strength and hence less deposition. Freeman et al. found that tubes with longitudinal grooves on the outside had less particulate fouling (by alumina particles) than the plain tubes.

The ERW tube specifications adopted by the ASME Code require, as a minimum, a flange test, a flattening test, and a reverse flattening test, which provide some control of steel quality and welding procedures. However, these required tests are only done on a frequency basis. Individual tube suppliers may perform additional destructive examinations
