1 Scope1.1 This specification covers the basic technical

requirements for the design, supply, installation andapplication of the Tarecpir® Process InsulationSystem for pipework, vessels and equipmentoperating at cryogenic, low or dual servicetemperatures.

It is particularly intended for external thermalinsulation applications on LNG projects and otherlow or dual applications in the petrochemical andgas process engineering industries where thereduction of heat gain and / or prevention ofsurface condensation are required. For the purposeof this specification the following temperatureranges are defined as follows:

● cryogenic service temperature range: –50°C to–200°C / -58°F to -328°F;

● low service temperature range: ambient temperature to –50°C / -58°F; and

● dual service: –50°C up to +200°C / -58°Fto +328°F.

1.2 Selection and installation of metal cladding is notincluded in this specification. Information and adviceon metal cladding is provided in BS 5970 and CINI.

1.3 If the insulation project is subject to anotherspecification, the design and execution of theinsulation works must be in accordance with thesedemands.

3 Design 3.1 General

3.1.1 The design and thickness of the Tarecpir® thermalinsulation for pipework, vessels and equipmentequipment operating at cryogenic, low or dualservice temperatures shall be to provide:

● prevention of condensation on the external surface of the insulation;

● temperature control of processes in pipework andequipment;

● personnel protection; and

● sound control.

3.1.2 As an alternative to the prevention of condensationon the external surface of the insulation, theinsulation thickness can be increased on the basis ofimproved heat gain limits, which will yield higherlevels of insulation.

The insulation thickness required for the preventionof condensation on the external surface of theinsulation and improved heat gain limits or thecontrol of process temperatures, will normallyexceed the required thickness for plant safety andpersonnel protection.

For determination of the thickness of insulationrequired for the prevention of condensation on theouter surface of the insulation refer to AppendicesC1 & C2.

For determination of the thickness of insulationrequired for improved heat gain limits and control ofprocess temperatures calculated for typical designand external ambient conditions refer to AppendicesC3 & C4.

Insulation thicknesses for ambient conditions notindicated in the Appendices need to be calculatedby the Kingspan Tarec Industrial Insulation TechnicalService Department.

3.1.3 It is essential that moisture does not penetrate theinsulation system. Moisture in the form of watervapour, liquid or ice reduces the thermal andstructural properties of all insulation materials andwill eventually lead to the corrosion of unprotectedunderlying metal surfaces.

3.1.4 Cryogenic and low temperature insulation of thickness50 mm / 2" or greater on pipework, equipment andfittings shall be applied with staggered joints. Thenumber of joints shall be kept to a minimum. Theminimum thickness of any layer in a multi layeredsystem shall be no less than 25 mm / 1".

3.1.5 A primary vapour barrier shall be applied to theexternal surface of the Tarecpir® Process InsulationSystem.

3.1.6 A factory applied secondary vapour barrier shall beapplied to the inner layer of a double layered systemand to the intermediate layer of a triple layered systemrespectively. The secondary vapour barrier shall be afactory applied Triplex Foil Vapour Barrier Jacket sealedwith self adhesive Triplex Foil Vapour Barrier Tape.

3.1.7 Vapour stops shall be provided at each terminationor interruption in the continuity of the insulationand vapour barrier.

3.1.9 Steel / aluminium cladding, if used, shall be installedand secured in such a manner so that the underlyinginsulation and the primary vapour barrier as specifiedin the CINI Specification is not damaged.

3.1.12 Parallel pipelines or equipment shall not beenclosed together with one covering of insulation,unless specially indicated for 'bundling'.

3.1.13 Painting of the surfaces to be insulated shall becarried out in accordance with the paintingspecification and schedule.

3.2.4 Where vessels or equipment are supported on metalsaddles, the saddles shall be insulated from thelowest point of the shell for a distance of four timesthe specified insulation thickness. The vapour barriershall be carefully fitted to the insulation.

3.2.5 Vessel skirts shall be insulated on both the insideand outside of the skirt for a distance from thebottom tangent line of the vessel equal to fourtimes the specified insulation thickness, but not lessthan 300 mm / 11.75".

Appendix B6 – Reinforcement Scrim

The Reinforcement Scrim has a synthetic fibre compositionthat provides for significantly greater elongation, recoveryand freedom from stress breakage. The ReinforcementScrim has a leno weave that gives stability to the fabric,eliminating the thread movement and distortion inherentto plain weave cloths. It will not detectably affect theflame spread and smoke developed ratings of the selectedmastic or coating.

The Reinforcement Scrim is easy to bond to and wets outreadily compared to glass cloth. This minimizes thepossibility of disbanding of tack and finish coats. Because itweighs only 0.9 ounces per square yard, about half theweight of glass cloth, the Reinforcement Scrim is easy towork with. A full roll can easily be “one handed” for afaster, trouble free installation.

The Reinforcement Scrim contains no asbestos, lead,mercury, or mercury compounds.

It can be used as a joint sealant inlow velocity duct air–conditioning systems and is ideal forsealing the laps of aluminium jacketing to prevent theingress of moisture.

The Joint Sealant is a fast drying vapour barrier sealant thatcan be top coated with most solvent–thinned, flexible,light coloured coatings without danger of bleed through.It is weather resistant and may be used outdoors withouttop coating.

Joint Sealant is the preferred product for flashingprojections and terminations where a complete moistureand vapour seal is required.
