Sampling and Injection Equipment
Corrosion, Deposition, and Chemistry Monitoring Equipment
A simple inexpensive device installed outside the turbine, which collects exfoliated oxides and mineral deposits representative of
deposition inside the turbine. Used for troubleshooting, testing chemistry effects, root cause analysis of deposition in turbines,
evaluation of composition and morphology, and determination of the time and type of operation when impurities are transported into
the turbine.
Used for troubleshooting corrosion and water and steam chemistry problems in steam turbines, feedwater heaters, BWR reactors, PWR
steam generators, heat exchangers, piping, and geothermal systems.
Droplets carrying dissolved impurities which impact the Probe are instantly converted back to vapor leaving behind the impurities
as deposits on the Probe surface. Used in corrosion investigations of disks, blades, stress corrosion cracking, corrosion fatigue,
etc.
Isokinetic sampling nozzles (probes) for sampling gases and liquids (including steam and water in steam plants). EPRI Nozzles
meet ASTM D1066-06 requirements.
Quills for injecting chemicals into liquids and gases (for example, into feedwater pipes in steam plants).
Guidelines
These comprehensive Guidelines, customized for a specific unit, cover water and steam chemistry control for utilities, industrial
units, and combined cycles for any type of water treatment.
Water and Steam chemistry and corrosion control is often a neglected area during the storage, erection, and commissioning of the equipment
when building new units.
Instrument for the continuous, inline, online monitoring of particle flow and concentration; Uses include monitoring of solid particles,
and colloids in gases and liquids, and liquid droplets and aerosols in gases.
On-line, inline instrument (calorimeter) which continuously monitors the heat (enthalpy) and moisture (quality) contents of wet steam.
An inexpensive, easy to install, in-line instrument for the continuous monitoring of steam systems. It can also be used for
liquid induction for other fluids.
Reduces or prevents air inleakage through turbine rupture disk and can be installed during operation.
Filling the boiler, deaerator, and feedwater system with deaerated water with low concentrations of oxygen and carbon dioxide leads
to minimization of iron and copper oxide scale formation and corrosion, faster startups (less iron and copper holds), and lower frequency
of chemical cleaning.
