Introduction

Our Competence is underpinned by Torgy Alantic Ltd, the UK based Division of Torgy Mek that specialises in the design and maerials Technology for Thermal Insulation & Thermal Isolation for Pipe & Vessel Supports.

�Thermal Insulation Cryogenic Pipe Supports (including PUF): Used where Process temperatures need to be maintained with a minimum Heat Gain.

�Thermal Structural Isolation Breaks for Hot & Cold process Pipelines & Vessels. Used where Process Temperatures on Hot or Cold Process Pipe-lines & Vessels need to be isolated from supporting steel structures for personnel protection or to allow lower grade structural steelwork to be used. [These materials are structurally stronger than Insulation materials but have higher thermal conductivity].

Marketed under the Globally recognised Atplas & ASEplas brands, Atlan-tics’ materials have been used in Piping & Vessel applications around the World for over 30 years without any reported failures. This includes high humidity environments where laminar wood materials are susceptible. Its portfolio includes PUF, and related fabrications required for major LNG, LPG and similar projects around the World.

Thermal Insulation

Cryogenic Supports (thermally Insulating) For use on LNG, LPG and similar processes where thermal efficiency & minimal process heat gain is required.

To help satisfy the Worlds ever increasing demand for Liquefied Gas Products, The Torgy Group has a ‘State of the Art’ PUF Design & Manu-factre Facility, utilising 3D Finite Element Thermal & Stress Analysis and CNC controlled Moulding & Machining Technology, to support its’ impressive Portfolio of Pipe Support Products & Services..

Over 30 Years of experience in moulding for the Worlds Oil & Gas proj-ects 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 can be in-cluded as an integral part of the mould if allowed by project standards.

Unlike conventional monolithic moulding, our innovative high preci-sion 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 cut-ting 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 me- �chanical 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’ types

Provides consistent dimensional tolerance �

Maintains dimensional stability throughout the full range of service �temperatures from -385°F/-196°C through +212°F/+100°C

Ensures no cutting & machining to achieve longitudinal gap required �for operational expansion & contraction.

Assured by 3D finite element thermal analysis whichallows the verifi- �cation of PUF shoe thickness selection.

Pipe Supports For High Temperature Insulation +1000°CWe have a range of specially formulated inorganic calcium silicate & foamglass materials suitable for the thermal isolation & insulation of high temp pipelines. Special consideration of the design application of these materials is essential as they are generally less tolerant of excessive dynamic loads than our range of organic materials, which are suitable for temperatures up to 160°C.

Pipe Supports for Hot (+160°C)& Cold (-196°C) Applications

ASEplas 1010 is a range of organic glass-reinforced polyester composites commonly used in thermal isolat-ing support systems. They have an excellent track record supporting cold pipes and vessels in oil, gas, pet-rochemical and pharmaceutical plants worldwide. These materials were formerly known as ATPLAS.

The ASEplas 1010 range has an advantage over many materials available in that they are mouldable and can be produced in a wide variety of shapes with properties that are basically non-directional. The materials have excellent fire safety properties; they are not easily ignitable and have a very low flame spread therefore on site welding can be safely carried out adjacent to an ASEplas support.

Under Pipe Supports

Application: An anti wear support and isolating block fitted between pipe and pipe rack to prevent corrosion caused by:

Wear from thermal movement � Galvanic action between dissimilar metals � Moisture build up �

Background: The under pipe support was designed in consultation with piping/cor-rosion engineers to provide a simple, inexpensive, easy to install means of protecting process pipes on pipe racks.

The simplicity and effectiveness of this product has produced rapid ac-ceptance by piping engineers who recognise it as an effective means of eliminating pipeline corrosion problems and expensive maintenance.

Three versions of the Under Pipe Support have been developed to suit a wide range of conditions, pipeline temperatures and client preferences:

Type A – Factory fitted narrow strip of adhesive for initial bonding during installation. Secondary adhesive to be applied according to clients requirements.

Type B – Factory fitted with full width of adhesive.

Type C – Supplied without adhesive for fitting using client’s choice of adhesive.

Type B products are intended for use where the primary objective is to provide an anti galvanic corrosion barrier between the pipe and the pipe rack and where only slight and/or infrequent movement between the pipe and rack is anticipated.

For general use where frequent and or significant movement between pipe and rack is anticipated we recommend the use of Type A products with the specified secondary adhesive system. Temperature range: The basic UPS shoe is continuously rated for use at temperatures between – 196°C and + 160°C. The adhesive pre-fitted in types A and B is continu-ously rated from –35°C to +95°C with intermittent excursion to +150°C. For applications in which the pipe temperatures lie outside those of the built in adhesive type C units should be specified with an appropriately rated adhesive.
