non destructive test ndt

understanding Non Destructive Testing (NDT) used in Oil and Gas industry

Non Destructive Testing In oil and gas industry (upstream, middle stream and down stream), we used advance inspection and non destructive testing or NDT. Advance inspection include ILI, Long range Ultrasonic testing, Short range Ultrasonic testing, UAV inspection and Ground Penetrating Radar survey / inspection. NDT used in inspection & maintenance daily job, turn around and project ( construction phase ). Every fixed equipment construction, use NDT as quality control tools. The purpose of NDT activity is to detect defects/discontinuity (above the surface, beneath the surface, and in a material). NDT measure the geometry of the objects and determine the[…]

ultrasonic pipeline inspection by pigging

pig cleaning system

what is pig cleaning system? each oil and gas company is required to carry out pipeline inspection activities. Inspection methods that are often used vary according to company requirements. starting from UT conventional, LRUT, MTM, visual inspection to the most sophisticated method, namely ILI or often called pigging. based on my 15 years of experience in the inspection field, this pigging method is the most perfect inspection method with a relatively cheap price compared to the LRUT method. This pigging inspection process is carried out by inserting pig in the pipe without interrupting the pipe operation or stopping the flow[…]

guided wave ultrasonic testing and LRUT basic

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) or GWUT (Guided wave ultrasonic 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[…]

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[…]
