understanding a pipeline pig detector

pipeline pig detector when doing a progressive cleaning pig or intelligent pig in a pipeline, workers install a transmitter on the back of the pig. This transmitter functions to transmit signals with distances of up to about 6 meters, but technically it can be up to 23 meters. Here are some types of transmitters that are often used: ITX 251, ITX 503, ITX 504, ITX 804 and ITX 806. ITX transmitters are available for all pipe sizes from 3 “to 56”. For smaller sizes up to 12 “, complete transmitter tools are available. For larger sizes, a bolt-on flange is used for easy mounting of the ITX to any cleaning or inspection tool. Transmitters can operate for quite a long time, which is up to 1000 hours. High signal range (distance up to 23m / 75ft) stainless steel housing so that it can be used on almost all types of fluids can be used on pipes with an operating pressure of 200 bar even on special requests, can be up to 300 bar pressure. can last up to 1000 hours. In some conditions, we can request special conditions so that the transmitter can withstand over 1000 hours. Maximum operating temperature[…]

pig cleaning system

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 in the pipe. Cleaning pigging vs smart pigging / ILI. Pigging operations include, but are not limited to, pipe cleaning and inspection. Cleaning pigging is used to clean the dirt in the pipe. impurities referred to include materials from the fluid itself or used material during pipe construction, namely sand, wax, scale, welding rod, gloves, etc. Smart pigging or ILI is used to determine the condition of pipe integrity, namely the thickness of the pipe, the sleeve attached to the pipe, the corrosion that occurs in the pipe and the features along the pipe. the data obtained is very detailed.[…]

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) 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. How guided wave ultrasonic testing work? The tools create Symmetric waves that transmitted along the pipe. The waves propagate along, not through, a pipeline. The wave is reflected from changes in the cross-section in a pipeline. The amplitude of the reflection depends on the total change in the pipe wall[…]

fluid mechanic calculation for centrifugal pump

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 speed. Fluid statics deal with silent fluid problems. Example: fluid in a glass, fluid in a pressure vessel, fluid in a reservoir, etc. Silent fluid is in equilibrium (the resultant force acting on it is equal to zero). In a silent fluid (fluid does not flow) there is no shear[…]
