Fastener Class Policoat
Developed to withstand the harsh chemical environment found at
petrochemical drilling sites Policoat protects fasteners against
a broad spectrum of chemicals and corrosives. Economically
desirable on steel bolts and nuts, this coating will not chip or
peel. resists oxidation, withstands extreme temperatures ( from
-420F to +600F ), fights hydrogen embrittlement, allows nuts to
be removed easily ( nut will not freeze ) and the fasteners to
be reused.
The " stainless steel " Alternative
Industries subjecting fasteners to extreme conditions have often
been forced to use stainless at high costs to solve their
problems. Policoat coated fasteners will survive normally
devastating conditions and are now being specified by industry
as an alternative to stainless - at greatly reduced costs.
Petrochemical Industry Policoat for Tubing and Rods
Coating tubing and rod with Policoat produces the ideal
permanently impregnated, slippery ( but tough ) suface for the
release of paraffin and GIP, helping to prevent buildup which
means longer production life, reduced maintenance frequency and
down time. Meanwhile, at the same time Policoat is also
protecting expensive parts from the corrosives found in the
nastiest wells including H2S and C02, extending their production
life while cutting replacement cost and frequency, applied as a
thin, non chip film to the ID of tubing as well as to the rod,
Policoat imparts long wear characteristics to metal on metal
wear surfaces, providing a long term permanently bonded
lubricant film. Policoat - the space age tool for modern
industry.
Galvanizing vs. Policoat
Galvanizing
• |
Galvanizing, a
thick zinc coating process which embrittles metals
and alloys endagering their strength. Thick coating
builds up in threads often requiring weaker
oversized nuts and retapping of threads. |
• |
Galvanized
fasteners fail completely in severely corrosive
conditions. |
• |
Torqued fasteners
are over stressed at threaded end since most of
torque is used up overcoming friction. |
• |
Galvanizing process
uses caustic tanks and chemicals hostile to the
environment. |
Policoat
• |
Policoat process
will not embrittle or harm metals. Typically applied
at .001' thickness, Policoat will not clog or
interfere with threads, allowing normal nuts to be
used. |
• |
Policoat provides
much greater corrosion protection in more hostile
environments than galvanizing, cad or zinc plating. |
• |
Policoat contains
materials with the lowest known coefficient of
friction allowing even torque loading along the
fastener and a reduced toque spec. |
• |
Policoat is a Dry
film coating applied by a proprietary process that
is not environmentally hostile involving no tanks or
caustic baths. |
