Our Quick
Flush high velocity pipe flushing will effectively flush piping, no
matter what the diameter, length or change in direction. This system
flushes piping using less liquid, minimal temporary piping and no
circulation pumps.
The
Quick Flush method generates a 20-foot frothed slug of liquid, which
is propelled at high velocity through the pipe by a gas. Travelling
at 50 to 80 feet per second, the slug has the force to remove debris
and loose scale safely and effectively. Each application of this technique
is engineered to generate Reynolds numbers and Froude numbers sufficient
to lift debris from pipe walls and transport the debris from the piping
system.
Advantages
No Need
for Circulation: Traditional methods incorporate pumps to circulate
large volumes of liquid cleaning solutions at slow velocities. In
some places fire hydrant pressures at 3-4 bars are used as once through
cleaning method. The Quick Flush method completely eliminates the
need for circulation and reduces the volume of waste solutions requiring
disposal.
Our process
employs non-alkaline detergent to remove oils and detergent-soluble
organic material. These chemistries are designed to meet environmental
requirements of any plant site. Our turnkey package includes temporary
equipment, detailed procedures, chemistry and site technicians to
complete the project.
Constant
High Velocities
The Quick
Flush method maintains constant high velocities even over long lengths
and during multidirectional changes in piping systems. It greatly
reduces the frictional losses experienced with a circulating system.
This increased efficiency translates into economies of time, personnel
and costs.
The viscosity
of the frothed air and mixture is many times that of either air or
water alone, thus the slug has a much greater capacity to suspend
solids until it exits the line. The fine dispersion of air bubbles
in the slug reduces density and creates a compressibility property
within the slug. In essence, the slug acts like a "foam pig",
however, this slug can conform to line size changes and pass obstruction
through which traditional foam pigs cannot pass.
Localized
Cavitation
The high
rates of shear generated at the pipe wall create a localised Cavitation,
which will remove loosely adherent debris. It is this type of gritty
debris often left by traditional flushing which results in damaged
pump seals and plugged control valves and heat exchangers.
