ENtank PLATING SYSTEMS For Electroless
Nickel
 Palm's
ENtank electroless nickel plating systems are the highest
quality available, and are supplied complete and ready to operate.
They are available either with solid stainless steel construction
(to be used with the
ENstat II anodic passivation system) or with a polypropylene
liner in a stainless steel shell. Only extra low carbon grade
Type 304 or 316 stainless steel is used to guarantee complete
resistance to nitric acid. Likewise, the polypropylene is stress
relieved, virgin material, welded or extruded with copolymer
rod under an inert atmosphere to ensure even expansion and freedom
from defects. These techniques, while more expensive than others,
significantly extend the life of electroless nickel systems.
The quality that Palm provides helps ensure that their equipment
will provide many years of reliable service.
Each tank includes an air spider, a sealless vertical centrifugal
pump, either an external ENheat
heat exchanger or stainless steel electric immersion heaters,
and filter bag holders, with all necessary piping and valves.
Systems and replacement liners are stocked in 50, 100, 150 and
200 gallon sizes, and plating tanks of any capacity can be fabricated.
Special designs for special applications with external filter
chambers, sloped bottoms, or solution agitation can also be fabricated.
Palm also fabricates stainless steel and polypropylene tanks
for electrolytic plating and for pretreatment. They are designed
for ease of operation, flexibility, and freedom from maintenance.
These tanks receive the same care and attention that is given
to electroless nickel plating tanks. Only 0.5 or 0.75 inch thick
sheet is used to fabricate polypropylene tanks, and all seams
are triple welded and spark tested at 20,000 volts. In addition,
the side walls of plastic tanks are often reinforced with steel
angle, painted and encapsulated with 0.25 inch thick polypropylene
covers.
Stainless steel tanks are also built from Type 304L sheet with
formed lips and girths. Single, double and triple counterflow
rinse tanks, complete with overflow weirs, water inlet spargers
and air spiders, are standard.
