HELICOFLEX®

High Performance Seals and Sealing Systems

Helicoflex Spring Energized Seals

GENERAL INFORMATION
The Helicoflex® seal represents the leading edge in seal technology for high performance sealing
applications. Today’s extreme sealing requirements have rendered traditional seals & gaskets obsolete.
If you can’t afford the lost time associated with leaks, put your trust in the leader: Helicoflex®.

SEALING CONCEPT
The sealing principle of the Helicoflex® family of seals is based upon the plastic deformation of a jacket of
greater ductility than the flange materials. This occurs between the sealing face of a flange and an elastic
core composed of a close-wound helical spring. The spring is selected to have a specific compression
resistance. During compression, the resulting specific pressure forces the jacket to yield and fill the flange
imperfections while ensuring positive contact with the flange sealing faces. Each coil of the helical spring acts
independently and allows the seal to conform to surface irregularities on the flange surface. This combination
of elasticity and plasticity makes the Helicoflex seal the best overall performing seal in the industry.

Temperature: Cryogenic to 1800°F (982°C)
Pressure:
Ultra High Vacuum to 50,000 PSI (100,000 PSI under special conditions)
Excellent springback: the spring energized Helicoflex is capable of compensating for flange
distortions due to temperature and pressure cycling.
Adaptable to a majority of standard flanges: ANSI, ISO, KF, ASA
Suited to different types of assemblies: -metal/metal with groove
-flat flanges with limiter/retainer
-3 face contact
Extended shelf life
Excellent resistance to corrosion and radiation
Minimum relaxation: the Helicoflex’s resilient spring
compensates for relaxation ensuring positive seal contact.

The resilient characteristic of the Helicoflex® seal ensures useful elastic recovery during service. This
elastic recovery permits the Helicoflex® seal to accommodate minor distortions in the flange assembly due
to temperature and pressure cycling. For most sealing applications the Y0 value will occur early in the
compression curve and the Y1 value will occur near the end of the decompression curve.
The compression and decompression cycle of the Helicoflex® seal is characterized by the gradual
flattening of the compression curve. The decompression curve, which is distinct from the compression
curve, is the result of a hysteresis effect and permanent deformation of the spring and jacket.

The intrinsic power of the Helicoflex seal reflects its ability to maintain and hold system pressure for a
given temperature at Y2 and e2. This value is expressed as a specific pressure and is noted by the
symbols Pu (room temperature) and Pu (at operating temperature). The influence of temperature on Pu
is shown in the graph above. The tables on pages 10 and 11 give the values of Pu at 68°F (20°C), Pu at
a given temperature and the maximum temperature where Pu = 0.

Note 1: wherever the working pressure is high and/or seal diameter is big, to such an extent that P•Dj
≥ 32 Ym, in order to remain on the safe side, whatever the inaccuracy on the tightening load may be,
it is recommended to take the Fj value in lieu of Fm for the calculation of Fs so that Fs = FF + Fj.

TARGET SEALING CRITERIA
The ultimate leak rate of a joint is a function of the seal design, flange design, bolting, surface finish and other
factors. Helicoflex seals are designed to provide two levels of service: Helium Sealing or Bubble Sealing.
Helium Sealing: These Helicoflex seals are designed with a target Helium leak rate not to exceed 1x10-9
cc/sec.atm under a ∆P of 1 atmosphere. The ultimate leak rate will depend on the factors listed above.
Bubble Sealing: These Helicoflex seals are designed with a target air leak rate not to exceed 1x10-4
cc/sec.atm under a ∆P of 1 atmosphere.

Note: Due to its circular cross section, the Helicoflex seal exhibits a “line” load instead of an “area load” typical of
traditional gaskets. As a result, “m”, “b” and “y” factors are not pertinent when applied to the Helicoflex seal. The
above equivalent equations were developed to assist flange designers with their calculations.

ANSI B16.5 RAISED FACE FLANGE
The Helicoflex® HN208a is ideally suited for standard raised face flanges. The resilient nature of the seal
allows it to compensate for the extremes of high temperature and pressure where traditional spiral
wounds and double jacketed seals fail. The jacket and spring combination can be modified to meet most
requirements of temperature and pressure. In addition, a large selection of jacket materials ensures
chemical compatibility in corrosive and caustic media.
