Pipe plugs are used with supplementary accessories such as air and water hoses, air and pressure control devices, gauges, adapters and chains depending on the type of the pipe plug and the process. Auxiliary equipment like compressors for inflating the pipe plugs, water tanks for filling the pipeline and pumps for some cases must be used.
Drill pipe (#16) is a joint of hollow tubing used to connect the surface equipment to the bottom hole assembly (BHA) and acts as a conduit for the drilling fluid. In the diagram, these are stands of drill pipe which are 2 or 3 joints of drill pipe connected and stood in the derrick vertically, usually to save time while tripping pipe.
GM – gas migration; GOC – gas oil contact; GOM – Gulf of Mexico; GOP – geological operations report; GOR – gas oil ratio; GOSP – gas/oil separation plant; GPIT – general-purpose inclinometry tool (borehole survey) [16] GPLT – geol plot log [clarification needed] GPTG – gallons per thousand gallons; GPM – gallons per Mcf ...
[1] [2] These fittings are used in plumbing to manipulate the conveyance of fluids such as water for potatory, irrigational, sanitary, and refrigerative purposes, gas, petroleum, liquid waste, or any other liquid or gaseous substances required in domestic or commercial environments, within a system of pipes or tubes, connected by various ...
The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.
A cleaning pig for a 710-millimetre (28 in) oil pipeline. The blue plastic disks seal against the inside of the pipe to propel the device and to remove loose sedimentation or scale buildup. The black rectangles at the top and the circular disks in the center are magnets to attract and remove any loose metal objects in the pipe.
Moreover, the 3D pipe stress determines the bending moments of the pipes. Allowable (ASME) Pipe grades permitted for Oil and gas industries are : Carbon Steel Pipes and tubes (A53 Grade [A & B], A106 Grade [B & C]), Low & Intermediate alloy steel Pipes (A333 Grade [6], A335 Grade [P5, P9, P11, P12, P91])
A plug nozzle design evaluated at the National Gas Turbine Establishment [8] was rejected for the Concorde engine due to the weight penalty from the required variable features and concerns about adequate plug cooling during reheat operation. [9] Plug nozzle model tests have shown reduced noise levels compared to traditional con-di nozzles. [10]
