Corrosion of low carbon steel in gasoline–water (brine)‎ mixture

الملخص EN

The application of two- phase flow are found in chemical & petroleum industry such As : production tubing, casing tubing, horizontal pipe lines, chemical reactors & refineries.

The aim of the investigation is to measure the corrosion rate of low carbon steel in gasoline water mixture at different temperature (303K, 313K and 323K) and different rotary speed (30r.

p.

m, 60r.

p.

m and 90r.

p.

m).

The gasoline concentration in mixture is ranging from (10 to 30 % v / v).

The corrosion rate measurement has been performed by the following techniques : 1- Weight loss 2- Polarization The weight loss result showed that the corrosion rate decrease as the gasoline percent increased & the corrosion rate increase with temperature & rotary speed increasing.

In catholic polarization the limiting current density decrease as the gasoline percent increased.

It is important to mention here the polarization experiments carried out in stationary condition at the temperature (303K+_ 273K).
