Description

1, PTFE Filament Packing

   Item: HY-S684

 

Description:Made of sintered, highly stretched PTFE multifilament yarns LENMENS with thoroughly PTFE impregnation. The packing is then re-impregnated with a mix of PTFE emulsion during braiding operation. Good resistance to compression and to extrusion, high structural and cross-sectional density.

 

CONSTRUCTION:

 

HY-S684R PTFE Filament Packing with Silicone Core

High red elastic rubber core can absorb vibration, to control leakage.

 

APPLICATION:

 

Especially suited for high pressure valves, plunger pumps, agitators, mixers etc. and where contamination is not permitted.

 

PARAMETER:

 

Style S684, S684R

Pressure Rotating 20 bar

Reciprocating 150 bar

Static 250 bar

Shaft speed 10m/s

Density 1.75 g/cm3

Temperature -150~+260°C

PH range  0~14

 

 

PACKAGING:

 

in coils of 5 or 10 kg, other weight on request; 

as precut length;

as packing rings---- S684, S684R

 

2, Flexible Graphite Packing

   Item: HY-S689

 

Description:Braided from low-sulphur expanded graphite yarns, which are reinforced by cotton or glass fiber. It has a very low friction, does not damage shafts or stems. It shows good thermal and chemical resistance and high elasticity.

 

CONSTRUCTION:

 

Other reinforcement materials are also available:

Glass fiber--------High strength, lower cost

Carbon fiber------Less weight loss

 

HY-S689F --Flexible Packing with Corrosion Inhibitor

Corrosion inhibitor acts as a sacrificial anode to protect the valve stem and the stuffing box.

 

APPLICATION:

                                  

HY-S689 & HY-S689F is a multi-service packing capable of a wide variety of uses throughout a plant. It can be used in valves, pumps, expansion joints, mixers and agitators in high-pressure, high-temperature hostile environments of hydrocarbon processing, pulp and paper, power stations, refineries and industries where effective sealing is vital.

Precaution: in oxidizing environment.

 

PARAMETER:

 

  Rotating  Reciprocating  Valves

Pressure 20 Bar 100Bar 300Bar-

Shaft speed 20m/s 2m/s 2m/s

Density 1.0~1.3g/cm3 

Temperature  

PH  0~14

 

 

PACKAGING:     

 

in coils of 5 kg, other package on request. 

 

3, Graphited PTFE Packing

   Item: HY-S684G

 

Description:Braided from graphited PTFE (gPTFE) plain yarn. The packing is soft, with low density There are no free particles of graphite on surface and therefore no contamination can occur. Both are economical "CGFO".

CONSTRUCTION:

 

HY-S684G A is a packing with A grade of quality, the yarn with good tensile strength, and excellent thermal conductivity.

HY-S684G B is economical gPTFE packing, braided from normal graphite PTFE yarn

 

4, Carbon Fiber Paking

   Item: HY-S691

 

Description:Braided from strong carbon continuous yarns after softening, impregnated with proprietary lubricants and graphite particles, which fill voids, act as a break-in lubricant, and block leakage.

 

CONSTRUCTION:

 

HY-S691W Carbon Fiber Packing Reinforced with Inconel wire

The Inconel wire reinforcement provides increased mechanical strength, usually for static.

 

5, Aramid Fiber Packing

   Item: HY-S686

 

 Description:Braided from high quality Dupont Aramid/Kevlar fiber with PTFE Impregnation and lubricant additive. Extremely hard wearing. It shows good chemical resistance, high elasticity and very low cold flow. It is wear resistant but may damage the shaft if not used properly. A minimum shaft hardness of 60HRC is therefore recommended. Compared with other kinds of packing, it can resist more severe media and higher pressure. The packing is also lubricated with a silicone-based compound for quick and easy break-in.

 

HY-S686L Aramid fiber packing with an inert lubricant

Without PTFE impregnation, An extremely durable, highly abrasive resistant packing, It is ideal for slurry service application.

 

6, Injectable Packing

   Item: HY-S699

7, Kynol Fiber Packing

Item: HY-S695
