Submersible Pumps:
Electric submersible pumps (ESPs)
: ESPs are used to generate the magnetic fields necessary for efficient and reliable motor operation. These pumps are commonly used for lifting oil and water from deep wells.
Teflon® (PTFE)
Teflon® (PTFE)
provides excellent protection under the harshest conditions. It has poor adhesion and is not suitable for glued assemblies. It is expensive and usually requires over-molding or press fitting to hold in place.
Tin (Ni-Cu-Ni-Sn)
Tin
is more cost-effective than gold and silver. It has some advantages in discoloration resistance; it is non-toxic, easily brazed, soft, and ductile.
Wellbore stability:
Wellbore stability
Magnets are used to stabilize wellbores by controlling the movement of metallic debris and particles, preventing them from interfering with drilling operations or causing wellbore instability.
Zinc (Zn)
Zinc
has reasonably good corrosion resistance and is a lower cost alternative to Nickel. It is a single layer coating that has good adhesion during assembly.
