HZDT Sealing; Braided Packing - Flexible Graphite Packing

GH-110

GH-110 Flexible Graphite Packing (NA)

Construction: This packing is manufactured from high purity flexible graphite that is expanded and formed into a braidable yarn and then braided without binders or wire reinforcement. It also contains corrosion inhibitor to prevent the electrical-chemical reaction. The finished product retains all the inherent benefits of flexible graphite: heat resistance, chemical inertness, low friction, self lubrication, and conforms readily.

Application: The outstanding properties of GH-110 make it a truly multi-service packing capable of a wide variety of uses throughout a plant. It may be used in valves, pumps, expansion joints, mixers and agitators in the hostile environments of hydrocarbon processing, pulp and paper, power generation, metal-working and other industries where effective sealing is vital.

GH-1108 Valve Stem Packing (NA)

Construction: The packing is manufactured from high purity flexible graphite that is expanded and formed into a weave-able yarn and then braided in a unique construction with wire reinforcement. It also contains corrosion inhibitor to prevent the electrical-chemical reaction. The finished product retains all the inherent benefits of flexible graphite; while the wire reinforcement provides greater mechanical strength.

Application: This packing is particularly suited for use in high temperature, high pressure steam service. In addition, it can also handle most chemicals, acids and alkalis. It is excellent for use in steam turbines, high temperature motor-actuated valves and for high pressure/high temperature valve applications in general.

GH-1900

GH-1900 Valve Stem Packing (NA)

Construction: This packing is braided over the core of GH-1108 packing, using high temperature fiber reinforced with Inconel wire braided the jacket, then coated with graphite and corrosion inhibitor. Result is a dense, long-lived, non-hardening packing, is readily die-formed and is easily removed. It also contains corrosion inhibitor to prevent the electrical-chemical reaction.

Application: The packing is especially designed for super-critical fossil fuel power plants and for all ranges of steam valves. Excellent on valves of steam turbines; automatic tube blowers; high temperature, motor-actuated slide valves; and on all general high pressure valving.

Service Limits:


Pressure (Bar)	--	--	400
Temperature (°C)	-200~650
Shaft Speed (m/s)	--
PH Range	2~12
