Quick couplers are in important part of any hydraulic
circuit system, providing optimum hydraulic fluid control and reliable
connections. Assessing the level of
corrosiveness of the application is a crucial factor in choosing quick
couplings. Incremental damage to
components varies based on low to high corrosive environments.
Assess Level of
Corrosiveness
Quick couplings are used in a multitude of industry sectors
from manufacturing, to Earth moving and agricultural equipment, oil and gas
extraction, food processing and many other applications. Quick couplers are
designed and manufactured to meet a variety of operating conditions based on
various factors to meet safety and productivity requirements.
Applications may be categorized from low to highly
corrosive environments:
●
Low corrosive environment:
an application with no specific
environmental conditions that would contribute to corrosiveness. As long as hydraulic fluids are maintained to
avoid contamination, damage is not expected to occur to hydraulic circuits
●
Medium corrosive environment: applications
which use corrosive fluids such as water based cooling systems
●
Highly corrosive environment: these
environments expose quick couplings to hostile elements which can exacerbate
corrosion such as in off shore oil processes
Quick Coupler
Materials to Combat Corrosion
Quick couplers are manufactured in various materials to
meet different specifications and environmental demands. The most popular materials used in the
manufacture of hydraulic quick couplings include:
●
Carbon steel – this
type of steel performs well in low corrosive environments with a good balance
between commercial and technical characteristics.
●
Brass – commonly used
in medium level corrosive applications with good resistance to medium corrosive
fluids
●
Stainless steel – used
in many processes, this is the material of choice for highly corrosive
environments including offshore platform applications
Stucchi Offers
Quick Couplers for Any Corrosive Environment
Stucchi offers quick coupling specialists and more than 60
years of experience in developing hydraulic quick connect solutions. We provide process analysis and custom
designed hydraulic solutions
to meet varying levels of corrosion. Our
quick coupler materials and treatments include:
●
Quench Polish Quench (QPQ) – QPQ plating is a heat treatment that provides good
resistance to corrosion combined with surface hardness.
●
Chrome 3 – this
surface galvanizing treatment is commonly applied to carbon steel using
chromium and zinc to increase resistance to corrosion
●
Zinc Nickel – this is
another surface galvanizing treatment which uses a special zinc alloy to
increase corrosion resistance as an alternative to Chrome 3
