Key Benefits of FEF Insulation Systems for LNG

SWICA Conference, Houston TX, 3rd February 2015


Security in Industrial, Marine and

Petrochemical Environments

Thermal insulation is necessary to maintan

process conditions and conserve energy

Acoustic insulation is necessary to control

noise thereby protecting the safety of our

workforce and of the local environment.

System failure and stand-still times due to CUI

(Corrosion Under Insulation) cause huge

losses to the operator.

Armaflex insulation systems offer thermal and

acoustic performance which reduces the risk

of CUI.

Multi-layered systems providing excellent

acoustic performance

Combines acoustic and thermal insulation

into one system

Creates substantial weight & space savings

ArmaSound Industrial Systems Cryogenic Systems – Armaflex LTD

Innovative material technology with low

temperature flexibility

For applications down to -180°C (-292°F)

Flexible materials which offer ‘built-in’

expansion/contraction capability

HT/LT Armaflex Industrial

Closed cell industrial insulation with high

resistance to water vapour transmission

Clean, ‘fibre-dust’ free materials which

satisfy strict fire requirements (IMO, E84)

Recognised solution to mitigate CUI &

SCC

Acoustic Systems Thermal Systems

Substantial benefits achieved by combining thermal & acoustics to provide thinner, lighter insulation systems

Ease of fabrication and install leads to lower install times

Benefits of FEF materials for minimising CUI


CUI Corrosion Under Insulation / The Challenge

CUI is often difficult to identify because it is hidden beneath

insulation and jacketing until it becomes a more serious

problem…

Advantages of flexible elastomeric foams

12

1. Vapour Resistance

► Closed-cell Armaflex foams have excellent resistance to water-vapour diffusion throughout the whole structure.

2. Low temperature performance

► Low-temperature flexibility to minimise thermal stress cracking and disperse mechanical impact (contraction joints not required)

3. Ease of installation

► Elastomeric foams are available in large sheets and pre-formed tubes which can be easily fabricated around complex fittings.

4. Thermal efficiency

► Armaflex LTD has excellent thermal conductivity of 0.030 to 0.020 W/m·K between temperatures of -50°C and -180°C.

Comparative weight and thickness

Reduced insulation thickness - offers considerable space saving.

Reduced insulation weight - reduces total loading on pipe supports.
