3300C – Slade’s Cost Effective Pump and Valve Packing
3300G – Slade’s Best All Purpose Pump and Valve Packing
300W - Slade''s Best Valve Packing
3300CJ - Slade''s Anti-Extrusion Carbon Fiber Packing
Installation
- Check clearances and dimensions
- Best to use no more than 5 sealing rings in stuffing box (use Slade”s Enviro-Foil Spacer Bushings to reduce rings)
- Cut sealing rings on the bias (45° angle), stagger joints
- Compress each sealing ring 25%-30% (use packing compressors as needed). Do not compress spacer bushings.
- Loosen gland to allow it to relax
- Snug the gland bolts
Advantages
Fire Safe
- Slade braided graphite foil is API Fire Test Certified
- API 589 First Edition
- API 607 Fourth Edition (modified by EXXON Specs)
- Tested by Southwest Research Institute
- Witnessed by 3 EXXON Engineers
- Temperatures to 1800°F/1000°C
- Tested at 5% of allowable standard
- Performed under a grant from the American Petroleum Institute
- Warning: Valves sealed with packings containing lubricants or blocking agents (PTFE) may cause secondary fires when exposed to the intense heat of a fire in another unit, which would cause packing shrinkage and leakage of flammable fluids causing a secondary fire.
- SLADE Patented Packings: rated FIRE SAFE
Emission Safe
- PERF Emission Standards
- Contact Slade for documentation
- EXXON-Emission Report:
- Emission tests, performed at a leading petroleum company”s test facility in Florham Park, NJ (using PERF procedures and standards), show that Slade patented, reinforced braided graphite foil outperformed standard die-formed graphite sealing rings.
- Slade reduced emissions by 74%.
- Corpus Report:
- A major Gulf Coast, USA refinery reports that 96% of the 325 valves packed with slade reported zero ppm emissions. Most of these valves were packed in the field by inexperienced installers.
- Cambridge Report:
- A major USA West Coast refinery reports that after 5 years, 96% of the 282 field installed valves were at zero emissions and that the 3,000 psi hydrogen control valves never went over 9 ppm during the 5 year test. Most of these valves were packed in the field.
