Based on the nominal diameter of the steel pipe and the required wall thickness, the specific size of the steel pipe can be calculated. Calculated as follows: a. The calculation formula for the outer diameter of the longitudinal submerged arc welded steel pipe for gas transportation is D=K*Φ...
How to Make a Gas Pipe Wall Mounted Shelf Gas pipe projects are becoming more and more popular. A simple internet search brings up a slew of gas pipe projects that show you how to build a bench, table with legs, hanging beds, and numerous shelf configura
In the first term of the right-hand side of Eq. (2), g represents the gravity acceleration and θ the pipeline inclination with respect to the horizontal direction, whereas in the last term of Eq. (2) S is the pipe's perimeter, τw is the shear stress on the pipe wall and A is...
Liquids in gas wells and pipelines in annular flow are removed by movement of the liquid film with the gas along the pipe wall and liquid droplets entrained along the high-velocity core. Physical and chemical conditions can increase or impede the movement of liquid. Chemicals modify fluid propert...
The chisels (8) in the chiselhead of the pipe cleaning appliance are held by resilient elements against the inside wall of the pipe and are swivel mounted at their front ends (9) on a housing head in which the housing has a rear supply openings and front drainage openings (24). When ...
The proposed closure relationships include correlations of wetted-wall fraction factor, liquid-wall friction factor, and interfacial-friction factor. An iterative calculation procedure is implemented to solve for liquid holdup and pressure gradient for a given set of operating conditions, pipe geometry,...

The ring has a laminar unit that is affixed at a cutting edge (4) between a smoke pipe and structural panel of a wall or outer wall layer. Separators are provided in the ring, where the dividers are manufactured from a pillar work. Length of the cutting edge between the structural panel...
A unified model to predict flow pattern transitions in horizontal and slightly inclined two-phase gas/shear-thinning fluid pipe flows. Int. J. Multiphase Flow 2016, 84, 279–291. [Google Scholar] [CrossRef] Sato, Y.; Sekoguchi, K. Liquid velocity distribution in two-phase bubble flow. ...
However, this is very subjective, and in early projects such as by Bennett et al. (1965), researchers formed a consensus through anonymous voting. Visual observations are also problematic, because the flow at the pipe wall is often obscured by bubbles or waves on wall films, particularly at ...
