Flexible Graphite Packings - Style 3000
Style
3000 Flexible Graphite Packing is manufactured from high purity
flexible graphite which is expanded and shaped into a graphite yarn and
then braided without wire reinforcement. The Flexible Graphite Packing
keeps all the original benefits associated with flexible graphite: great
heat resistance, chemical inertness, low friction, self lubrication.
The
fantastic attributes for this Flexible Graphite Packing make it ideal
for different service purposes within a plant. Flexible Graphite Packing
could be used in valves, pumps, expansion joints, mixers and agitators
in the aggressive environments of hydrocarbon processing, pulp and
paper, power generation, metal-working and other industries where
successful sealing is necessary.
Besides
the Compression Flexible graphite packing, the graphite packing can be
reinforced by added materials such as ss304 wire, ss316 wire, inconel
wire, carbon fibers, fiberglass, cotton fiber and so on. The density of
the packing is about 1.2g/cm3. And sizes from 3mm to 60mm.

Features and Advantages of Flexible Graphite Packing
Flexible
Graphite Packing offers economical alternatives to asbestos fibers
packing, lessen maintenance time and charge. It is easy to setup and
work as a good seal in used or oversize stuffing boxes. The braided type
and construction of the flexible graphite packing optimize reliability
and also steadiness in high temperature ranges, provide fantastic
chemical substance resistance, and dissipates heat speedily. Apparatus
goes much cooler as well as requires a lot less flush water. The braided
gland packing can include a not aggressive corrosion inhibitor like
Zinc Powder. No more end ring material is required with regard to valve
installations.
What is Flexible Graphite Packing Used For:
Style
3000 Flexible Graphite Packing is definitely precise to seal all sort
of industrial valves, making use of all liquids and gases, with the
exception of the strong oxidizers. Perfect for by using in rotary pumps
and valves in power stations as well as boiler houses, in the
petrochemical industry and many other industrial spots. Stay away from
combustion gas and also heat over 450°C. The valve's pressure has to be
under 100 bar if the packing is not helped by high tension wiper.

The best way to set up Flexible Graphite Packing correctly as well as Cut.
The
necessity of using compression braided gland packing for pumps
correctly simply cannot be overemphasized. A number of packing failure
problmes are caused by inappropriate installing of the packing. The
following tips are actually developed to make sure the most effective
setting up packing on pumping systems:
Eliminate all the outdated packing out of the stuffing box: Clean up box and also shaft totally and also examine your shaft or
sleeve. Remove and take the place of shaft or sleeve when a lot wear.
Use the appropriate cross section of packing or die-forming rings: To determine the proper packing dimension, measure the diameter of your
shaft (inside the filling box area when possible) as well as after that
measure the diameter of the stuffing box (to give the outer diameter of
the ring). Subtract the inner diameter size coming from the outer
diameter measurements and divide by two. The result will be the needed
measurements.
When using coil as well as spiral packing, often cutting the packing into different rings: Do not ever wind a roll of packing into a stuffing box. Braided Gland
Packing Rings can be cut into butt shape (rectangular), bias or diagonal
joints, based on the construction. Our recommendation is that flexible
graphite packing be cut only by butt (sq) technique. The easiest method
to cut braided gland packing rings is usually to cut the packing on a
mandrel with the same diameter as the shaft on the filling box area.
When there is not shaft abrasion, rings can be cut on your shaft away
from the stuffing box. Contain the packing tightly on the mandrel,
nevertheless tend not to stretch out extremely. Cut the ring as well as
insert it into your stuffing box, making certain it will fit the packing
place properly. Every single added ring can be cut on the same manner,
or the very first ring might be used as a master in which the balance of
the rings are cut. It is actually needed the fact that rings be cut
towards the right measurement. In any other case, service life is
diminished. This is when die-cut rings are actually of wonderful
benefit, as they provide the precise ring measurements for your inner
diameter of the shaft as well as the outer diameter of the stuffing box.
There is absolutely no waste materials on account of falsely cut rings.
Setup one ring at one time: Be sure that it can be thoroughly clean, as well as has not collected
any dirt in delivering. If perhaps desired, lubricate the shaft within
the stuffing box. Seat rings firmly (except PTFE filament or Graphite
yarn packing, which ought to be snugged up very carefully, next
tightened stage by stage after the pump is on steady flow). Joints of
subsequent rings must be staggered and also held at the very least 90
degrees a part. Every unique ring ought to be firmly seated with a
tamping device. If enough rings have already been individually sitting
so your nose of the gland will get to them, unique tamping really should
be compounded by the gland.
Right
after the very last ring is certainly installed, take up mounting bolts
finger snug or slightly snugged upward. Tend not to jam the packing into
area by excessive gland launching. Start off pump, as well as take up
bolts until such time as leakage is lessened to a tolerable minimum.
Make sure gland bolts are taken up equally. Quitting LEAKAGE ENTIRELY
After All This WILL CAUSE THE PACKING TO BURN UP.
Enable
packing to leak freely once establishing a newly packed pump:Abnormal
leakage over the 1st hours of procedure will result in a better packing
job during a longer amount of time. Take up gradually on the gland as
the packing seats, until finally leakage is lowered to a endurable
degree. Do not ever attempt to avoid leakage entirely, except if we
indicate it is safe and sound to do so. Hot Tags: Flexible Graphite Packing, China, Manufacturers, Suppliers, Factory, Wholesale
