Cryogenic Supports (thermally Insulating) For use on LNG, LPG and
similar processes where thermal efficiency & maintenance of process
temperatures are critical.
To help satisfy the Worlds ever increasing demand for Liquefied Gas Products,
The Torgy Group has recently added a ‘State of the Art’ PUF Design & Moulding Facility, utilising 3D Finite Element Thermal & Stress Analysis
and CNC controlled PUF dispensing Technology, to its’ already impressive
Portfolio of Pipe Support Products & Services..
Over 30 Years of experience in moulding for the Worlds Oil & Gas projects
ensures a competence in PUF moulding to provide our clients with a competitive
premium quality product by combining high quality polyurethane
materials with CNC dispensing technology and precision mould tools to
produce an optimum density moulding.
Utilising Innovative Moulding Technology, this state of the art facility starts
at the tool design stage where all steps and joint lines are included as an
integral part of the mould
Unlike conventional monolithic moulding, our innovative high precision
tooling technology has been developed to overcome the need to cut at
the centre line, thus maintaining the integrity of the all important moulded
skin, and ensuring consistency.
The moulding is far superior to all other forms of PUF that utilise cutting
as some part of its’ process, providing assurance to our clients with cradles
that:
- Provides clean, sharp edges that fit neatly with the adjacent pipe line
insulation
- Produces a closed cell foam structure that provides optimum mechanical
strength and resistance to moisture ingress
- Produces monolithically moulded segments ensure that the full
clamping force exerted by our dynamic clamping system is transferred through to the pipe, giving better resistance to both axial thrust and torsion.
- Provides higher cryogenic thermal stress/shock resistance than cut
from ‘Bund’ typesProvides consistent dimensional tolerance
- Maintains dimensional stability throughout the full range of service
temperatures from -385°F/-196°C through +302°F/+150°C
- Ensures no cutting & machining to achieve longitudinal gap required
for operational expansion & contraction.
- Assured by 3D finite element thermal analysis which allows the verification of PUF shoe thickness selection.

- NB on multi-layered requirements, radial & longitudinal joints are staggered
by minimum of 25 mm in accordance with Industry Standards
to help avoid potential break-down of the vapour seal, and to aid fitup
to Line Insulation on Site.
- Protection of the Vapour Barrier is provided by a suitable thin gauge
steel or Aluminium wrap.
- HD PUF is generally supplied in the following densities, but this can be
altered to suit client needs:
Pipe Size (NB) PUF Cradle (kg/m3) Up to 150 160 200 to 600 224 over 600 320
