High Temperature Packing Applications

Browse our range of mechanical gland packing best suited for high temperature packing applications.

K466M

Construction

KLINGER style K466M is a KLINGER®-Lock packing, produced from high quality, self-lubricating carbon yarn, dipped in PTFE and finished with Moly.

Services

Due to the nature of the construction of this packing, it will not burn, blaze or fail due to loss of lubrication.

The excellent heat transfer capabilities of the carbon yarn, along with the lubricant used, makes K466M ideal for high temperature and pressure applications.

Typical Applications

  • HP steam valves
  • Petro-chemical valves and pumps
  • Power generation valves and pumps
  • Acid slurry pumps
  • Pulp and paper process pumps
  • Soot blowers

Reported Values of Performance*

Temperature Range-240°C - 430°C -650°C - Steam
Pressure Range 0 - 115 Bar**
Sliding Velocity 20 m/s
pH Range 0 - 14

K3222

Construction

Cross braided from expanded graphite, this product is self-lubricating, chemically inert, soft and compressible.

Services

K3222 can be used on all clean service centrifugal type pumps and valves. It is widely used in the petrochemical, pulp and paper and power generation industries.

Do not use this packing in applications with chromium trioxide, nitric acid and sulphuric acid. 

Typical Applications

  • Vacuum pumps
  • Boiler feed pumps
  • General service pumps
  • Cooling water pumps
  • LP and MP steam valves
  • Petrochemical valves

Reported Values of Performance*

Temperature Range-200°C - 430°C
Pressure Range0 - 180 Bar**
Sliding Velocity20 m/s
pH Range0 - 14

K7301C

Construction

Glass and ceramic yarn braided into square packing.

Services

High temperature valve packing for air, flue gas, and many other applications.

Typical Applications

Static/door seals in steam boilers, reformers, furnaces, kilns, brick car damper seals, radiant tube packing for heat treat furnaces, thermocouple tubes in heat exchangers, insulation of pipelines, exhausts and pipeline expansion joints.

Reported Values of Performance*

Temperature Range0°C - 700°C
Pressure Range 0 - 5 Bar
Sliding Velocity0 m/s
pH Range3 - 9

Style 333

Construction

Made of ultra-high purity graphite fiber with helically braided inconel wire inside. The core is extra dense to provide dimensional stability throughout the working temperature/pressure range of Style 333. Braid blockage is provided by a unique dispersion containing ultra fine graphite particles locked in place by the SealRyt® patented process.

Services

Style 333 is recommended for all valve and soot blower applications. Best suited for very high pressure and high temperature valves. Specifically designed for valves with worn or suspect stem conditions.

Typical Applications

  • All valves
  • Soot blowers
  • Petrochemical valves
  • Reciprocating applications

Reported Values of Performance*

Temperature Range Oxidizing: 0°C - 430°C
Non Oxidizing: 0°C - 2760°C
Pressure Range0 - 840 Bar
Sliding Velocity0 m/s
pH Range1 - 14

Style 396

Construction

A dense version of braided flexible graphite with effective placement of high purity carbon filament yarns to resist extrusion and aid in bending around tight radii.

Services

Style 396 operates successfully in valves except knife-gate configurations. Within the established temperature/pressure/pH parameters, adding additional rings allows 396 to fill previous shaft scoring. Style 396 has also been successful in rotary applications where flush free, leak free performance has been desired. May be used on valves with anti-extrusion bullrings for exposed clearances and very high pressures. Most effective at controlling fugitive emissions. Effective for irregular or worn valve stems

Typical Applications

  • All valves
  • Petrochemical valves
  • Power generation valves
  • Rotary and reciprocating valves

Reported Values of Performance*

Temperature RangeOxidizing: 0°C - 430°C
Non Oxidizing: 0°C - 2760°C
Pressure Range 0 - 360 Bar
Sliding Velocity20 m/s
pH Range1 - 14

Style 396C

Construction

A patented core of Style 333, an internally-sprung high temperature, high pressure graphite packing, over braided with carbon filament inserted exfoliated graphite foil. Style 396C is the most effectively designed product on the market today for the sealing of fugitive fuel emissions. Style 396C meets or exceeds all requirements of A.P.I. 589 and 607 tests as well as the A.P.I. fire test for soft-seated quarter-turn valves.

Services

Style 396C is unlike other exfoliated graphite products which offer various other yarn or wire placements to theoretically address extrusion, blow-out prevention, etc. Style 396C utilizes its patented Style 333 core, capable of withstanding 5800 PSI alone, to provide a highly-sprung internal structure which enables 396C to conform and re-conform through constant thermal cycling to various stem, bore and clearance conditions in various states of degradation.

Typical Applications

  • All valves
  • Petrochemical valves
  • Power generation valves
  • Fugitive emissions control

Reported Values of Performance*

Temperature Range-150°C - 430°C
Pressure Range0 - 45 Bar*
Sliding Velocity20 m/s
pH Range0 - 14

K35 - Die-formed graphite packing and pressure seals

K35 Die-Formed Rings offer a leak free sealing solution for high performance valve applications which require excellent pressure and temperature
characteristics.

The manufacturing process ensures a product that is volumetrically stable – without fillers or binders. K35 rings are also essentially impermeable and without porosity. 

General Properties

  • Graphite is a self-lubricating material. This ensures that there is no abrasion or wear of valve shafts or stems.
  • K35 rings have outstanding chemical resistance and are unaffected by the majority of chemical media employed within industry.
  • The material has excellent thermal conductivity and thermal resistance.
  • K35 die-formed rings are therefore unaffected by fluctuations during application, such as thermal cycling.
  • Can be used with braided header and footer rings for high pressure applications.

Availability

KLINGER can manufacture virtually any size, section or density of die-formed ring. Required information: 

  • OD, ID and ring height
  • Section and profile
  • Endless, halved or split rings
  • Density
  • Depth of stuffing box
  • Also available in 99.85% pure nuclear grade
