3.1 Oilfield Measures and Units. The domestic United States oil and natural gas industry uses a very specific set of measures and units that were common at the dawn of the industry and, at least in the U.S., have been retained and expanded upon over the years. These units are often called Oilfield Units. 6 Common Oilfield Injuries - Platte River Injury LawFires and Explosions. When working around gas, fires and explosions are always a concern. Fires can occur when pressurized gas erupts and makes contact with sparks. Fires on an oil field can be tough to extinguish, considering the large volume of gas. Fires and explosions can lead to a variety of injuries, including severe burns and head injuries.

Roughness of pipe is required for friction factor estimation. The chart shows the relationship between Reynolds number and pipe friction. Calculation of friction factors is dependant on the type of flow that will be encountered. For Re numbers <2320 the fluid flow is laminar, when Re number is >= 2320 the fluid flow is turbulent.

This Help!! - Magnetized Oilfield PipeWith oil field pipe you could have an alloy pipe that is susceptible to cracking. Go to a low-hydrogen electrode like E7018 and if you are still having problems after the preheat, then you may try a post weld heat. This will reduce the cooling rate and help with the cracking.

Similar to the oil pipeline, the roughness factor, was varied from 1×10-6 to 0.006. Note, for a roughness factor greater than 0.006, a higher inlet pressure, a larger diameter or lower flow rate was needed. The calculated friction pressure drop as a function of roughness factor is presented in Figure 2. Liquid Applied Internal Flow Coatings for Oil surface roughness of an unlined pipe ranges from 35-85 microns. The velocity of the oil being transported, typically 2mtr per second to 2.5mtr per second on an unlined pipe creates turbulence within the product. As the oil becomes more and more agitated by the roughness of the internal surface of the pipe , friction is created.
