Product Description

Acu-Tech sells a range of Flange Gaskets for pipe connections, including rubber gaskets, fibre gaskets, and steel reinforced gaskets. Used for both fluid and gas applications, these flange rings are available in a variety of materials, depending on the operating medium, the operating conditions and the design requirements. Pipe gaskets can be made from neoprene, nitrile, EPDM rubber or fibre, and are made to match bolted pipe flanges. If you are unsure what type of flange gasket to use, contact our friendly customer service team today!

FLANGE GASKET RINGS – KC6327 2 mm FIBRE

KC6327 is a gasket material based on SBR-bound aramid fibres and inorganic fibres. Its key feature is a relative softness and high compressibility which enables sealing under lower bolt loads than most other fibre gaskets. Following the correct flange installation procedure and using the correct bolt torques is critical to long term flange joint integrity. Contact us for more information and a copy of our Flange Joint Installation Guidelines. Looking for flange gaskets made to your specifications? Please contact us as we supply a wide variety of fibre and rubber gaskets to order.

STEEL-CORE PROFILE RUBBER FLANGE GASKETS

Tired of battling with leaking gaskets, flange mis-alignments and time-consuming torquing/ re-torquing procedures? Get the job done quicker and eliminate leaks with the revolutionary Steel-Core profile rubber gaskets! These rubber gaskets are reinforced with the Steel-Core ring, which makes them rigid and prevents extrusion/ leaks under higher pressures which is a problem with plain rubber gaskets. They also have a special O-ring profile which increases sealing performance dramatically, effectively two sealing mechanisms in one gasket.

KEY BENEFITS:

  • Effective sealing under low bolt torque loads
  • Compensation of small surface imperfections
  • Flange face misalignment is more easily compensated than flat gaskets, especially the fibre type
  • Seal maintained even with a small degree of flange movement
  • Higher durability of plastic flange joints due to lower torques helping to prevent distortion
  • Lower tensile grade fasteners required, providing cost savings
  • Steel-Core ring is vulcanised within the centre of the gasket, preventing corrosion
  • Will withstand pressures of up to 4,000 kPa (20°C) depending on flange
  • Made in Germany

Industry Guideline Information about Flange Gaskets

PIPA Industry Guidelines ‘Metal Backing Flanges for use with Polyethylene (PE) Pipe Flange Adaptors’ highlights areas that a specifier of a PE flange joint should consider when making an informed choice about which gasket (if any) should be used. It is recommended that specifiers consult with the gasket supplier. The following is a list highlighting elements of the application and joint assembly that should be considered when selecting a suitable gasket. This list does not attempt to cover all aspects and hence specifiers should not be limited to only those the aspects raised below. Aspects to consider in gasket selection:
  • Operating pressure, including surge allowance.
  • The ability of the gasket to seal at the clamping pressure imposed and resist blow-out without suffering excessive stress relaxation.
  • Operating temperature
  • Materials of mating flanges and the potential impact of surface finish, flatness, surface roughness and coatings.
  • Compatibility of the gasket materials with the medium being transported within the pipe at the operating temperatures and pressures. For flanged joints intended for use with potable water the gasket material must comply with AS/NZS 4020.
Gaskets may not be necessary when using PE flanges provided sufficient compressive load can be applied (i.e. sufficient bolt torque) and the sealing surfaces are not excessively rough or damaged. Non-gasketed joints are common place in the US and to a lesser extent in the UK and Europe. Historical Australian practice has been to use gaskets. Acu-Tech also sells flange bolts and gaskets, blind flanges, and galvanised backing rings, or steel backing rings.
