What does ptfe means?
p.t.f.e. means polytetrafluoroethylene. The most famous brand name for PTFE is Teflon.
Why you use saturated steam in steam tracing?
If you use saturated steam, the main source of the heat is provided by the condensation of the steam at a constant temperature. The energy provided by the condensing steam is significantly more than what you can get from just changing the temperature of superheated steam. When the temperature remains constant, design calculations are also a lot easier; the temperatures stay the same (or almost the same) for the steam along the entire run and the pressure stays the same (or almost the same).
What is process pipework?
it is any type of piping that carries fluids or gases to effect processes on machinery or equipment
When was PTFE teflon tape first used for plumbing applications?
I believe around the 1970's
Why you use boiler in oil refinery?
Use of water in a refinery is makeup for boiler feed. The chief uses of steam are for stripping, steam distillation, and vacuum distillation. The steam comes in contact with the products in these operations, and generally the steam condensate is so highly contaminated that it cannot be reused for boiler feed or for other purposes. Steam is also used for process heating, for pumping, and, in some refineries, for generating electric power
What was the first use of Polymer PTFE?
nothing
What is the most common use of type B compression?
on internal cold water supply pipework is wrong answer
What is polytetrafluoethylene?
PolytetrafluoroethyleneIn chemistry, polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that finds numerous applications. PTFE is most well known by the DuPont brand name Teflon.PTFE is a fluorocarbon solid, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water and water-containing substances are wet by PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine. PTFE has one of the lowest coefficients of friction against any solid.PTFE is used as a non-stick coating for pans and other cookware. It is very non-reactive, partly because of the strength of carbon-fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE reduces friction, wear, and energy consumption of machinery.
Is PTFE non biodegradable?
PTFE is not biodegradable. It can be degraded by pyrolysis or radiation.
Frictional resistance within a cold water pipework system is influenced most by the?
number of elbows in the pipework
What is CMV pipework?
shortened version of type of steel pipework, found in power plants in boiler area

Can teflon be recycled?
PTFE does not have it's own recycling code symbol. However, PTFE can be recycled into many other products. Recycled PTFE can be used for rods, tubing, tape and more
Materials used to seal joints steam pipes?
it will be depend on the application, however following material are generaly used for pipe sealing -asbestos sheed - PTFE -composite sheet(Rubber+asbestos)
What is the Most common use of type b compression fitting?
