The origin is debated, but the earliest patents related with plugging the pipes date back to the 1890s. The first patent for a pipe plug as we know today is by Oscar F. Anderson, published in 1952., [3] and the first patent for inflatable plugs was published in 1965 [4]
The four-way valve or four-way cock is a fluid control valve whose body has four ports equally spaced round the valve chamber and the plug has two passages to connect adjacent ports. The plug may be cylindrical or tapered, or a ball.
Currently in most countries the plastic in/out catheters have to be discarded after use. There is a study currently under way called "Single use versus reusable catheters in intermittent catheterisation for treatment of urinary retention: a protocol for a multicentre, prospective, randomised controlled, non-inferiority trial". [4]
A 3-way plug valve could also be designed to shift flow between ports 1 and 2, 2 and 3, or 1 and 3, and possibly even connect all three ports together. The flow-directing possibilities in multi-port plug valves are similar to the possibilities in corresponding multi-port ball valves or corresponding multi-port valves with a rotor. An additional ...
Fire hose used to apply water or other fire fighting agent directly to a fire or burning substance. Typically of 2 + 1 ⁄ 2 inches (64 mm) diameter or less in the United States. Historically 1.5 inch hose was the primary initial attack line but has been supplanted in most of the US by 1.75-inch-diameter (44 mm) hose that carries 175 gallons ...
In plug flow, the velocity of the fluid is assumed to be constant across any cross-section of the pipe perpendicular to the axis of the pipe. The plug flow model assumes there is no boundary layer adjacent to the inner wall of the pipe. The plug flow model has many practical applications. One example is in the design of chemical reactors ...
An inflatable [1] is an object that can be inflated with a gas, usually with air, but hydrogen, helium, and nitrogen are also used. One of several advantages of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape.
BP – bridge plug; BPD – barrels per day; BPH – barrels per hour; BPFL – borehole profile log; BPLUG – baker plug; BPM – barrels per minute; BPV – back pressure valve (goes on the end of coiled tubing a drill pipe tool strings to prevent fluid flow in the wrong direction) BQL – B/QL log; BRPLG – bridge plug log
