Downstream cryogenic insulation systems DESIGNED FOR QUICK INSTALLATION AND REDUCED WASTE

Downstream cryogenic insulation systems2

The products are supplied as moulded pipe sections and

pipe fittings including elbows, tees and valve boxes. They

are quickly and easily installed in a single layer without

the need for contraction joints which significantly reduces

labour requirements and lowers installation costs. Their

unique structural make-up results in minimal wastage,

low dust generation and low risk of damage through

handling.

Features and benefits

• Reduces labour requirements for insulation by upto 60 per cent

• Quicker and easier to install without the need forcontraction joints

• Reduces wastage by up to 95 per cent as theproduct is manufactured in precision moulds

• Improvement in OHS – minimal dust generationdue to hard-wearing cellular structure that resistsabrasion

Created specifically for Liquefied Natural Gas (LNG) applications, the Matrix Cetrafoam™ moulded pipe insulation products restrict the inflow of atmospheric heat into the pipe or process equipment keeping the liquid cold and allowing it to retain its form.

Downstream cryogenic insulation systems

• Improvement in quality assurance (QA) -fewer installation processes involved

• A ductile product with low friability makes it tolerant to mechanical abuse from transportation and site installation

• Greater structural stability and flexibility

• Low environmental impact - no CFC, HCFC or hydrocarbon blowing agents used

• A range of insulation thicknesses available

• Excellent fire resistance

• Tensile modulus ≤6 at mpa - 165° C

• Leachable chlorides ≤25 ppm

• Supplied as single and multi-layer cylindrical pipe sections up to 1,000mm in length and with an OD of up to 1,100mm

Technical data

Downstream cryogenic insulation systems4

Cetrafoam™ pre-insulation products are installed onto

any length or diameter of straight length pipe before

the pipe is transported to site for installation. Pre-

insulation significantly reduces costs as insulation can be

completed before the pipes are installed on-site, which

allows for earlier progression of insulation work.

Used by LNG producing companies and EPC contractors,

the system can pre-insulate any diameter and length of

pipe including transfer lines, rundown lines and load out

lines, vapour return lines and unloading lines at LNG

terminals.

Cetrafoam™ fixed end design pre-insulation system

Features and benefits

• Reduces installation time

• Pre-insulates any diameter and length of pipe

• Reduction in on-site hazards - fewer contractorson-site as insulation work is completed off-site

• Superior insulation properties

• No insulation contraction joints required

• Better sealed against moisture ingress

• Less waste material - insulation is moulded to therequired size

• Moulded insulation cylinders cover the length ofthe pipe and are bonded to the pipe at either end

• Double vapour barrier

• Disbonded GRP/GRE cladding on the outside

The installation process

1 Cetrafoam™ moulded insulation cylinders are threaded onto the pipe and held in place between locking pieces.

2 Bonded to the pipe at each end with cryogenic adhesive.

3 Cigarette wrapped double skin vapour barrier is applied to the Cetrafoam™ insulation providing additional insulation and doubling the protection against moisture ingress.

4 Vapour stops are installed at each end of the Cetrafoam™ moulded insulation providing a fully sealed system against moisture ingress.

5 Factory applied cladding for mechanical protection can be metal jacketing or glass fibre reinforced epoxy (GRE)/glass fibre reinforced plastic (GRP). To protect the service life, UV cured GRE/GRP is factory painted.

6 A fully sealed cladding contraction joint absorbs differential thermal contraction between the pipe and cladding. Contraction joints are not required in Cetrafoam™ moulded pipe insulation.

7 After the pre-insulated pipe is welded into the line, Cetrafoam™ infill insulation is installed between the supports and the pre-insulation. Contraction joints are not required in Cetrafoam™ infill insulation sections.

8 The installation of the double-skinned vapour barrier and protective cladding is completed and sealed to the supports to ensure the GRE/ GRP is anchored at the supports.

This rigid composite syntactic material is used for

insulation and support in subsea and cryogenic

applications. With high mechanical strength and low

thermal conductivity, Xirtherm™ C140 is placed between

structural elements to restrict the flow of thermal energy.

Xirtherm™ C140 is used for pipe and vessel supports,

trunnion supports, and subsea supports requiring

insulation in flow assurance applications. It is a unique

material manufactured from epoxy resins and ultra-high

strength glass microspheres.
