Code, Standard and handbook in oil and gas industry

Code, Standard, and handbook are terms that are very often heard in the environment of Engineers and professionals working in the oil and gas industry. In general, the standard is a technical definition as well as instructions directed at the designer, manufacturer, operator or user of a piece of equipment. Whereas the Code is a standard that has been recognized by a government agency and authorized by law. So that the Code is stronger and binding because it is a legal document. The Handbook is very detailed and very complete technical information about a particular theme. For example, the ASM Handbook Volume 13 concerning corrosion. In the Handbook explained the basics of the theory of corrosion that is very complete. including the basic theory of how to measure corrosion rates in a laboratory. Whereas ASTM G102 is a Standard for Rates and Related Information from Electrochemical Measurements. If we want[…]

what is mechanical engineering jobs in oil and gas industry?

what is mechanical engineering? The field of Mechanical Engineering deals with the design of mechanical and thermal systems based on the principles of physics, mathematics and material science. Research activities by lecturers and students in the Mechanical Engineering Study Program include fields: Applied Mechanics, Energy, Materials Engineering and Manufacturing. Research within the Department has a significant impact on society and the scientific community.  In mechanical engineering, we apply the principles and problem-solving techniques of engineering from design to manufacturing.  We analyze our work using the principles of motion, energy, and force to make sure that designs function safely, efficiently, and reliably, and of course at a competitive cost. Mechanical engineers may design a component, a machine, a system, or a process. This ranges from the macro to the micro, from the large systems to the small components like instrumentation sensors or switches.   What are Mechanical Engineering Tasks description? in[…]

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 metal that usually considered :   yield strength ultimate strength allowable stress at elevated temperature strain modulus of elasticity hardness toughness poison ratio coefficient of expansion   Performance of material depends on its properties, which in turn is a function of its structure; Furthermore, the structure is determined by how[…]

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 operating conditions at high pressure and temperature, then we will need material that has high strength property and holds at high temperature. There is only a rare chance that a material has a maximum or ideal property combination. So, it may be necessary to trade off one property to gain[…]
