HYTORC Bolting System Assures 100 Percent Leakproof Flange-Connection

    HANOVER and MUNICH, Germany, March 15 Bolted flange
connections with seals can be very problematic.  Leakage may cause
disruptions, shutdowns or accidents with far reaching consequences for people
and environment.
    It is interesting that almost all leakage and the resulting failures and
consequences are not a result of the seals being used but of the bolting
techniques and methods being applied.
    The problem is, that seals extrude.  In effect after bolting procedure the
seal will creep after a certain time.  This creep will result in the loss of
clamping force and leakage will result.
    The american / german company HYTORC in Munich, which is represented
worldwide, will show a newly developed bolting-system at the HANNOVER-FAIR.
This system makes it possible even on space restricted flange connections with
integral seals to apply several hydraulic torque wrenches simultaneously from
a single hydraulic power supply with up to 700 bar (10.000 PSI) pressure.
    Force is applied to the flange evenly allowing for parallel closure and an
even load on the gasket-seal. With this hydraulic bolting system a predictable
and accurate clampload is achieved by relating the torque value to a
previously established bolt load with a repeatability of + 0.4 percent.  The
benefit of the designed Automatic Electronic Alignment (AEA) is: Prior to
loading up joint bolts, both joint faces are first brought into parallelism
without any load on the closed end -- automatically, without fail, without
operator's involvement.
    For example, a flange with 20 bolts M 42 and Nuts with Hexsize 65 mm
across the flats an B-7 bolting material requiring 5.100 Nm Torque can be made
up in about 20 minutes.  The flange stays tight.
    Time consuming tensioning and extensive space requirements for tensioners
and bridges are no longer required.
    The international company HYTORC is the oldest and largest manufacturer of
Hydraulic Torque wrenches and Bolting-Technologies.  The production is in
Mahwah, New Jersey USA.  The german company HYTORC, a Division of Barbarino &
Kilp, was settled in the year 1730 in Munich and represents HYTORC in Germany,
Austria and Switzerland.  HYTORC wins a lot of Quality and Innovative-Awards
in Germany, USA and Japan.  HYTORC is certified by ISO 9002.  The owners of
these two companies are John Junkers / USA and Peter Junkers / Germany.
