Sealing solution for worn and damaged flanges

A deformable structure seal is saving process businesses hundreds of hours in downtime by removing the need for machining damaged and worn joint flanges

Designed and manufactured by Garlock Sealing Technologies the Helicoflex range of Omicron seals provide a proprietary solution to maintaining joint integrity.

Working on the sealing principle of plastic deformation, the outer material of the seal is more ductile than the flange face material.

The seal outer material encloses a close wound, oval shaped helical spring.

This internal spring resists compression and causes the outer 'sealing' material to deform and permanently contact the flange sealing surfaces.

Dependent on the process Helicoflex Omicron seals are available in a range of jacket (contact) materials including aluminium, mild steel, nickel and stainless steel.

When specified as original equipment, the seal mechanical and material properties protect flange faces from wear, resist corrosion, radiation and extremes of temperature.

Operating temperatures of -269C to 750C and sealing levels of up to 1,000 bar for liquids and gas leak rates of below 10e-8 Atm.cm3/s make the range suitable for a wide range of applications, including - process lines, boilers, reforming pipe, corrosive gases, nuclear and petrochemical industry.

Helicoflex Omicron seals are available from Garlock (Great Britain) in standard ISO PN and Flange Classes.

Mean diameter sizes up to 692mm are stocked with larger diameters available on request.
