Pipecutter Cutting copper pipe with a close quarters tubing cutter. A pipecutter is a type of tool used to cut pipe. Depending on the metal of the pipe, a pipecutter can often provide a faster, cleaner and more convenient way of cutting pipe than using a hacksaw. There are two types of pipe cutters.
These comprise a clamshell or chain-mounted cutting head holding a tool steel and feed mechanism which advances the tool a set amount per revolution round the pipe. Tools may be styled to cut and/or prepare the bevel for welding in a single or multiple passes. High pressure abrasive water jets can be used for cold cutting. This technology is ...
Also Abrams' water-cement ratio law. A law which states that the strength of a concrete mix is inversely related to the mass ratio of water to cement. As the water content increases, the strength of the concrete decreases. abrasion The process of scuffing, scratching, wearing down, marring, or rubbing away a substance or substrate. It can be intentionally imposed in a controlled process using ...
Tube Tools can be categorized into function by application: Tube Cleaners-tube cleaning demands vary widely by application Shell and tube heat exchangers, condensers and chillers: Deposits are typically sediment from impurities in the water circulating through the tubes. Manual scrubbing with a wire brush attached to a long rod is the ...
CITHP – closed-in tubing head pressure (tubing head pressure when the well is shut in) CIV – chemical injection valve CK – choke (a restriction in a flowline or a system, usually referring to a production choke during a test or the choke in the well control system)
Using an always-open or always-closed valve called a tap, pipe layers connect them to a wider system and bury the pipes. whereas, Pipe fitters plan and test piping and tubing layouts; cut, bend or fabricate pipe or tubing segments; and join those segments by threading them, using lead joints, welding, brazing, cementing, or soldering them together.

A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate. A semiconductor diode , the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals.
