guided wave ultrasonic testing for pipeline inspection in oil and gas industry

Why choose guided wave ultrasonic testing pipeline inspection? LRUT (Long range ultrasonic testing) or sometimes called as GWT (guided wave testing) is becoming commonplace today for ultrasonic pipeline inspection. This technology is used as excellent NDT for the screening tool. Guided wave ultrasonic pipeline inspection offer many advantages such as High productivity (km per day), access required only at discrete locations, carried out with pipe on-line ( not require shutdown) and 100% coverage except for flanges, tees and other large features. This LRUT/GWT technology come as a solution for pipeline inspection problem like restricted access, many lines not suitable for in-line inspection (ILI / pigging inspection), regular UT and RT techniques are typically not cost-effective or typical UT and RT coverage 0.1%. After conduct LRUT/GWT screening and found some anomaly or “indication”, the inspector will dig the anomaly with other NDT tools such as UT scanning or UT Flaw detector.[…]

Fluid mechanic application in oil and gas industry

What is fluid mechanic? In the oil and gas industry, we are dealing with fluid mechanic problems every day. What is fluid? What is the nature and character of the fluid? To solve this problem we need to understand fluid mechanic basic. Mechanics is physics that deals with stationary objects and moves in the influence of forces. 1) Branches of mechanics that deal with stationary objects are called statics, and 2) The branch of mechanics that deals with moving objects are called dynamics Fluid mechanics is the science that deals with the nature of the fluid in a state of silence (fluid statics) or fluid in a moving state (fluid dynamics), and the interaction of the fluid with solids or other fluids at the surface of its boundary. Fluid mechanics is often also called fluid dynamics by looking at silent fluid as a special case of fluid moving at zero[…]

piping and pipeline, the most frequent equipment in oil and gas industry for mechanical engineer

Piping and pipeline in oil and gas industry There are many types of equipment available in the oil and gas industry. Which one I should learn first? For a fresh graduated mechanical engineer, I suggest you learn about piping and pipeline. Piping is similar equipment with the pipeline. The design of piping is similar to pipeline design. The piping inspection method is similar to pipeline inspection. Piping location is inside of a plant. Pipeline location is outside the plant. If you expert in piping, you will be an expert in the pipeline. Compare to other equipment like a pressure vessel or tank, piping/pipeline is the most frequent equipment. There are a lot of jobs available in piping and pipeline area. You can choose many jobs whether in the engineering phase, construction phase or in the maintenance phase. If you choose to focus on the engineering phase, then you need to[…]

Introduction to piping system in Oil and Gas Industry

Piping system In the oil and gas industry (especially in the downstream and upstream), we recognize 3 types of piping system, i.e. Process plant piping system, non-process plant Piping system and Utility piping system. The process Plant piping system is sometimes referred to as process piping. As the name suggests, this piping system is closely related to the reaction process inside the plant that processes raw materials into ready-to-sell materials. For example, in Ammonia Plant, the raw material is natural gas and the product is an ammonia liquid with a temperature of -33 deg C. Process piping is very closely related to the product of a plant, not just as a support facility. Nonprocess plant piping system is a piping system that is not directly related to the final product of the plant or piping system that serves as a supporter of a more important system. For example is a[…]
