Product Description

Model KXT P401 · Graphite + Metal Wire

Graphite Packing Reinforced with Metal Wire — SS304, SS316 or Inconel Wire Reinforced Flexible Graphite Braided Packing

Graphite Packing Reinforced with Metal Wire (KXT P401) is a braided packing made from expanded graphite yarns, with each yarn reinforced by a SS304, SS316 or Inconel metal wire. Kaxite manufactures this wire-reinforced graphite packing for valve stems, pumps and static sealing where high pressure, high temperature and extrusion resistance are required.

KXT P401 combines the sealing efficiency of braided graphite packing with the mechanical strength of metal wire reinforcement. The packing operates from -200 °C to +550 °C, from pH 0 to 14, with a density of 1.25 g/cm³, a rotary speed limit of 12 m/s, and pressure ratings of 30 bar (rotary pump), 100 bar (reciprocating pump) and 280 bar (static sealing).

What It Is

What is Graphite Packing Reinforced with Metal Wire?

Direct answer: Graphite Packing Reinforced with Metal Wire is a braided packing made from expanded graphite yarns, where each graphite yarn is reinforced with a metal wire — typically SS304, SS316 or Inconel. The wire reinforcement gives the packing greater mechanical strength, high pressure resistance and extrusion resistance compared to plain graphite packing, while keeping all the inherent benefits of flexible graphite: self-lubrication, non-hardening, dimensional stability and resistance to gases, fluids, heat and chemicals.

Aramid/Graphite Yarn Core

Expanded flexible graphite yarn provides the sealing element. Self-lubricating, non-hardening, dimensionally stable, and resistant to gases and fluids as well as heat, pressure and chemicals.

Metal Wire Reinforcement

SS304, SS316 or Inconel wire is braided into each graphite yarn. The wire provides greater mechanical strength, high pressure resistance, extrusion resistance and excellent thermal conductivity.

Jacket Braiding Construction

High temperature flexible graphite and Inconel wire filament jacket braiding affords mechanical stability, while the advanced construction provides leakage control and high integrity in service.

Certified Low-Emissions Technology

Certified Low-Emissions Packing Technology, suitable for valve stem service where VOC or fugitive emissions are regulated.

Long Service Life, Lower Cost

Long service life in high-cycle valve and pump service reduces packing replacement frequency and total cost of ownership.

Wide Temperature and pH Range

Working temperature -200 °C to +550 °C and pH 0 to 14, suitable for nearly all industrial chemical services except strong oxidizers.

FAQ

Frequently asked questions about Graphite Packing Reinforced with Metal Wire

Q1What is Graphite Packing Reinforced with Metal Wire?

Graphite Packing Reinforced with Metal Wire is a braided packing made from expanded graphite yarns, where each yarn is reinforced with SS304, SS316 or Inconel metal wire. The metal wire increases mechanical strength, high pressure resistance and extrusion resistance while keeping the sealing performance of flexible graphite.

Q2What wire material is used in KXT P401 graphite packing?

KXT P401 is normally reinforced with SS304 or SS316 metal wire. For higher temperature or stronger chemical service, Inconel wire reinforcement is available. Specify the wire material when requesting a quote.

Q3What is the temperature range of KXT P401?

The working temperature range of KXT P401 is -200 °C to +550 °C. The upper limit assumes an inert or reducing atmosphere. In oxidizing atmospheres the graphite upper limit is lower — confirm the specific service with Kaxite's technical team.

Q4What pressure can KXT P401 handle?

KXT P401 is rated at 30 bar for rotary pump service, 100 bar for reciprocating pump service, and 280 bar for static sealing. These are the standard ratings; for higher pressures contact Kaxite for a combination packing or die-formed ring solution.

Q5What is the pH range of KXT P401?

The pH range of KXT P401 is 0 to 14, covering the full acid-to-base range. The only exception is strong oxidizing media such as concentrated nitric acid, fuming sulfuric acid and hot concentrated chromic acid — graphite is not suitable for these services.

Q6What is the rotary speed limit of KXT P401?

The rotary speed limit is 12 m/s. This makes KXT P401 suitable for most industrial centrifugal pump and rotary pump shafts. For higher speeds consider a different packing grade — contact Kaxite for selection guidance.

Q7What cross-sections does KXT P401 come in?

KXT P401 is supplied in square cross-sections from 3×3 mm to 25×25 mm, in 5 kg or 10 kg spools. Custom cross-sections and die-formed rings are available on request. Send the stuffing box dimensions for a die-formed ring quotation.

Q8How is KXT P401 different from flexible graphite packing without wire?

The base graphite yarn is the same. The difference is the SS304, SS316 or Inconel wire braided with each graphite yarn. The wire provides greater mechanical strength, high pressure resistance and extrusion resistance — see the Flexible Graphite Packing page for the non-wire version.

Q9What is the MOQ and lead time for KXT P401?

MOQ depends on cross-section and spool size. Sample lead time is typically 5–7 days. Production lead time for standard and custom orders is typically 15–25 days after order confirmation.

Q10Can Kaxite supply die-formed graphite rings with the same material?

Yes. Kaxite manufactures Die-Formed Graphite Rings from the same expanded graphite material for valve stem and pump shaft service. Provide the stuffing box ID, shaft OD and packing height for a die-formed ring quotation.
