what are the energy forms

What is Energy? what does this term mean? because We hear about energy everywhere. why we hear about it everyday? and how important it is? We pay bills for energy every month, Athletes eat high-energy foods, and put as much energy as they can into the swing or the kick or the sprint. we hear this word many […]

what does Erosion-Corrosion mean

Erosion-Corrosion Likelihood –  API RP14-E is not valid in presence of solid particles (sand) –  It is not valid in vertical flow (even if it is used as well) –  It is not valid for gas systems (where no definite velocity limits are identified). – Alternative models have been proposed (as SalamaModel)/ or typical critical […]

What is Gasoline

Gasoline Gasoline (also referred to as motor gasoline, petrol in Britain, benzine in Europe) is a mixture of volatile, flammable liquid hydrocarbons derived from petroleum that is used as fuel for internal combustion engines such as occur in motor vehicles, excluding aircraft The boiling range of motor gasoline falls between –1°C (30°F) and 216°C (421°F) and has […]

Lubricating Oils Testing Methods

INTRODUCTION Lubricating oil is used to reduce friction and wear between bearing metallic surfaces that are moving with respect to each other by separating the metallic surfaces with a film of the oil. Lubricating oil is distinguished from other fractions of crude oil by a high (>400°C/>750°F) boiling point In the early days of petroleum refining, […]

Corrosion and Corrosion Inhibitors

Corrosion Corrosion is defined as the destructive attack of a metal by the environment, by chemical or by electrochemical processes (as contrasted with mechanical means such as the erosion of a metal structure by sand in the desert). Corrosion includes conjoint mechanical and chemical action to produce early failure of a load-carrying metal structure, eg. […]

Scale and Sclae Inhibitors

  what is Scale? Scale is normally a buildup of salts of calcium, barium or strontium as calcium carbonate, barium sulfate and strontium sulfate. Carbonate scale is caused by the presence of calcium and bicarbonate ions in the formation water. When pressures are decreased or temperatures are increased, the bicarbonate will begin to decompose, resulting […]
