material properties of metal that extensively used in oil and gas facility

In general, the materials used in oil and gas facilities are classified into 3 basic groups: metals, ceramics, and polymers. This scheme is primarily based on the chemical makeup and atomic structure. However, metallic materials are the most widely used group.   Metal for example, carbon steel, Alloy (stainless steel etc), aluminum, copper, titanium, and nickel. Atoms in metals and alloys are arranged in a very regular and relatively dense manner. With regard to mechanical characteristics, these materials are relatively stiff and strong, but ductile (ie, capable of large deformations without fracture), and are resistant to fracture. Material properties of[…]

what is the best material used in oil and gas facility

do we need the best material at any cost? In the oil and gas industry from upstream to downstream using various types of metal materials. This material is used for operating temperature – 40 oC to 1,000 oC. How do we choose the best materials for oil and gas facilities? Facility engineers are often confronted with conditions to choose the best type of material. In general, there are 3 main criteria that are often used. 1. best material for possible operating conditions. These operating conditions will largely determine the required material properties. For example, we will use pressure vessel on[…]

what is wet corrosion in oil and gas industry?

wet corrosion There are many ways to classify corrosion. However, in general, corrosion is divided into 3 major groups namely Wet corrosion, Dry corrosion, and biological corrosion. Wet corrosion, as the name implies, occurs only in the presence of an aqueous solution or an electrolyte. Dry corrosion or dry corrosion occurs when there is no fluid present or temperature above the dew point of the environment. Biological corrosion or biological corrosion is a specific type of wet corrosion that occurs in the presence of living organisms. sometimes wet corrosion is named as aqueous corrosion. Wet corrosion is an electrochemical process,[…]

What is the best practice of corrosion monitoring ?

why we need to conduct corrosion monitoring? Corrosion monitoring is an activity to check corrosion happened in an equipment. before we conduct a corrosion monitoring, we must understand the basic of corrosion and corrosion type.¬†Corrosion is the destruction or degradation of a metal due to a redox reaction between a metal and various substances in the environment that produce undesirable compounds. The most common example of corrosion is iron corrosion. In the event of corrosion, the metal undergoes oxidation, while oxygen (air) is reduced. The metal rust is generally an oxide or carbonate. The chemical rust formula is Fe2O3.nH2O, a[…]
