RELEASE THE STATIC MONSTER
Special consideration should be given to the transportation of flammable liquids through linings that incorporate a grounded metal backing, such as a steel pipe lined with PTFE or other plastic. The electrical volume resistively of PTFE-lined pipe is 10/18 ohm-cm. This value is characteristic of highly insulating materials capable of accumulating dangerous levels of static charge for several ours, even days. Materials having less than or equal to 10/9ohm-cm are considered to be static dissipative/conductive.
Due to the large, effective capacitance of the PTFE against a steel housing, large surface-charge densities may be formed. These densities give ris to highly energetic, light-like sparks in rapid succession known as propagating brush discharges. Such discharges have the potential to ignite most flammable atmospheres and can even ignite some of the more sensitive dusts. Pinholes in the PTFE liner may also be formed by these strong electrostatic charges. If left unchecked, these pinholes will cause premature pipe failure which will lead to chemical leaks and subsequent environmental concerns.
Through a proprietary process, static dissipating PTFE resin is compression molded around and through a 304 stainless steel, perforated, metal insert. After oven sintering, the porous-free, static-dissipating PTFE resin 100% encapsulates the stainless insert, isolating it from any fluid contact while in service. TASK-LINE® lined pipe grounding paddles have conductivity / static dissipating properties (volume resistivity) of less that or equal to 10/6ohm-cm
NO MORE FABRICATION OR GASKETS
TASK-LINE® lined pipe grounding paddles are molded to size, 1” through 6” (other sizes available upon request) in class 150# ANSI ratings with a thickness of 1/8”. The paddle handle extends 2” above the flange and is pre-drilled for grounding hardware and cable (included). TASK-LINE® lined pipe grounding paddles self-align and seat easily to any 150# ANSI, lined pipe flange and never require gaskets.
TASK-LINE® BENEFITS
TASK-LINE® lined pipe grounding paddles have a temperature range from cryogenic to +400°F and are chemically resistant to: all chloride’s, all sulfates, all bleach solutions, all solvents, all phenols, all caustics, and all peroxides. TASK-LINE® grounding paddles’ unusual non-stick property eliminates/reduces ion formation, oxidation and scale build-up, all of which can render alloy paddles useless. TASK-LINE lined pipe grounding paddles come complete in ket form with everything needed for a quick and easy installation.
TASK-LINE® GROUNDING PADDLES ARE NON-CONTAMINATING
Independent laboratory testing has proven that TASK-LINE® grounding paddles are non-contaminating and non-leaching, This means there is no possibility of process contamination. (Test data available upon requests.)
TASK-LINE PERFORMANCE
In terms of performance and longevity, no other grounding paddle compares. When installed between two, lined pipe flanges and grounded to a suitable earth ground, TASK-LINE® lined pipe grounding paddles provide a path for static discharges to exit the hostile atmosphere generating inside the lined pipe. The strength of the metal insert inside the grounding paddles provides critical blowout-proof protection. TASK-LINE® grounding paddles can also help protect instrumentation devices from inaccurate reading and damage when exposed to static discharges.
