3 Design 3.1 General

3.1.1 The design and thickness of the TarecTM

pir thermal insulation for pipework, vessels and equipment equipment operating at cryogenic, low or dual service temperatures shall be to provide:

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

l temperature control of processes in pipework and equipment;

l personnel protection; and

l sound control.

3.1.2 As an alternative to the prevention of condensation on the external surface of the insulation, the insulation thickness can be increased on the basis of improved heat gain limits, which will yield higher levels of insulation.

The insulation thickness required for the prevention of condensation on the external surface of the insulation and improved heat gain limits or the control of process temperatures, will normally exceed the required thickness for plant safety and personnel protection.

For determination of the thickness of insulation required for the prevention of condensation on the outer surface of the insulation refer to Appendices C1 & C2.

For determination of the thickness of insulation required for improved heat gain limits and control of process temperatures calculated for typical design and external ambient conditions refer to Appendices C3 & C4.

Insulation thicknesses for ambient conditions not

indicated in the Appendices need to be calculated

by the Kingspan Technical Service Department.

3.1.3 It is essential that moisture does not penetrate the insulation system. Moisture in the form of water

vapour, liquid or ice reduces the thermal and

structural properties of all insulation materials and

will eventually lead to the corrosion of unprotected

underlying metal surfaces.

3.1.4 Cryogenic and low temperature insulation of thickness 50 mm / 2” or greater on pipework, equipment and

fittings shall be applied with staggered joints. The

number of joints shall be kept to a minimum. The

minimum thickness of any layer in a multi layered

system shall be no less than 25 mm / 1”.

3.1.5 A primary vapour barrier shall be applied to the external surface of the Tarec

TM


System.

3.1.6 A factory applied secondary vapour barrier shall be applied to the inner layer of a double layered system

and to the intermediate layer of a triple layered system

respectively. The secondary vapour barrier shall be a

factory applied Triplex Foil Vapour Barrier Jacket sealed

with self adhesive Triplex Foil Vapour Barrier Tape.

3.1.7 Vapour stops shall be provided at each termination or interruption in the continuity of the insulation

and vapour barrier. Vapour stops shall be installed

at each side of all fittings, flanges, valves and

supports at the lowermost point of vertical

pipework greater than 4 m / 13’ in length and

other components. For detailed drawings refer to

Appendices D20 & D21 .

3.1.8 The design of contraction joints and their positions shall be based upon the expected differential

contraction between pipework or equipment and

insulant as a result of extreme temperatures. For

dimensions refer to Appendix C7. For detailed

drawings refer to Appendices D12 & D13.

3.1.9 Steel / aluminium cladding, if used, shall be installed and secured in such a manner so that the underlying

insulation and the primary vapour barrier as specified

in the CINI Specification is not damaged.

5


3.1.10 On vertical pipework and vessels, insulation support rings shall be provided at intervals not exceeding

4.5 m / 14.75’. Support rings shall be designed

in such a manner so as to minimise the area of

contact with the cold surface and shall not extend

beyond half the thickness of the outermost layer of

insulation.

3.1.11 The layout of pipework, vessels and equipment shall be designed in such a manner so as to provide

sufficient space for the application of the full

specified thickness of insulation and finish.

A minimum clearance of 75 mm / 3” between the

external surface of the insulation and the adjacent

surfaces or obstructions shall be provided.

3.1.12 Parallel pipelines or equipment shall not be enclosed together with one covering of insulation,

unless specially indicated for ‘bundling’.

3.1.13 Painting of the surfaces to be insulated shall be carried out in accordance with the painting

specification and schedule.

3.1.14 Contact between dissimilar metals having potential for galvanic corrosion shall be avoided.

3.2 Extent of Insulation 3.2.1 Pipework and equipment within the scope of this

specification shall be completely insulated and

shall include for all pipe fittings, drains, equipment

nozzles and supports to the thickness and extent

specified. Instruments shall be insulated when

specified.

3.2.2 All metal components such as legs and supports etc. protruding through the insulation shall be

insulated to the same thickness as the insulation

for the pipework, vessels or equipment and fully

vapour sealed. The length of the insulation shall

be at least four times the insulation thickness,

with a minimum of 300 mm / 11.75” bare metal

after the termination of the insulation, in order to

maintain a proper temperature rise and to prevent

condensation inside the insulation.

3.2.3 Where it is not possible to insulate protrusions as described in 3.2.2, a thermal break of high density

material shall be incorporated into the design.

3.2.4 Where vessels or equipment are supported on metal saddles, the saddles shall be insulated from the

lowest point of the shell for a distance of four times

the specified insulation thickness. The vapour barrier

shall be carefully fitted to the insulation.

3.2.5 Vessel skirts shall be insulated on both the inside and outside of the skirt for a distance from the

bottom tangent line of the vessel equal to four

times the specified insulation thickness, but not less

than 300 mm / 11.75”. Vents on skirts shall be filled

with rigid polyurethane foam and vapour sealed

with a primary vapour barrier.

3.2.6 Gauges shall be provided with extended connections to allow the application of insulation

against condensation or frost.

Appendix B6 – Reinforcement Scrim

The Reinforcement Scrim has a synthetic fibre composition

that provides for significantly greater elongation, recovery

and freedom from stress breakage. The Reinforcement

Scrim has a leno weave that gives stability to the fabric,

eliminating the thread movement and distortion inherent

to plain weave cloths. It will not detectably affect the

flame spread and smoke developed ratings of the selected

mastic or coating.

The Reinforcement Scrim is easy to bond to and wets

out readily compared to glass cloth. This minimizes the

possibility of disbanding of tack and finish coats. Because

it weighs only 0.9 ounces per square yard, about half the

weight of glass cloth, the Reinforcement Scrim is easy to

work with. A full roll can easily be “one handed” for a

faster, trouble free installation.

The Reinforcement Scrim contains no asbestos, lead,

mercury, or mercury compounds.

Appendix B7 – Joint Sealant

The Joint Sealant is a fire resistive, flexible butyl elastomer

based vapour barrier sealant. It is designed for sealing

joints in insulation (except polystyrene foam), metal and

masonry wherever the maintenance of a water–tight and

air–tight seal is required. It can be used as a joint sealant

in low velocity duct air–conditioning systems and is ideal

for sealing the laps of aluminium jacketing to prevent the

ingress of moisture.

The Joint Sealant is a fast drying vapour barrier sealant

that can 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 without

top coating.

Joint Sealant is the preferred product for flashing

projections and terminations where a complete moisture

and vapour seal is required.

Appendix B8 – Vapour Stop Sealant

Vapour Stop Sealant is a one part elastomer based product

used as a vapour barrier sealant in the joints of cellular

glass and urethane foam board stock insulation. It remains

soft and flexible, preventing damage to the insulation due

to thermal cycling through a wide range of temperatures.

Vapour Stop Sealant is primarily used with low

temperature insulation to prevent the migration of water

and water vapour into the insulation system via butt joints.

Vapour Stop Sealant is supplied in a special “buttery”

consistency, which facilitates application to insulation

surfaces without stringing or excessive drag. It may be

applied at temperatures as low as 10°C/ 50°F without

difficulty.

Vapour Stop Sealant does not contain asbestos, lead,

mercury or mercury compounds.

black elastomeric Vapour Stop Adhesive / Cryogenic

Coating designed for use in cryogenic and specific chemical

resistance applications. It is suitable for application

to polyurethane foam, cellular glass and fibrous glass

insulation in conjunction with aluminium, steel, wood and

masonry construction materials. Vapour Stop Adhesive /

Cryogenic Coating has excellent resistance to moisture,

water vapour and other gases in addition to most oils, mild

solvents, inorganic acids, inorganic bases and salt solutions.

Vapour Stop Adhesive / Cryogenic Coating is suitable for

bonding and sealing lap joints in plywood and metal and

for adhering glass cloth to itself and other surfaces.

It can function both as a vapour barrier and adhesive in

very low temperature applications where a water vapour

tight insulation system is required. It is an excellent vapour

stop material.
