Q
Why does the flexible ULT insulation system not require a moisture barrier?
The system has a unique closed cell structure and a specialized polymer blend formulation. This low-temperature elastomeric material is highly resistant to water vapor permeation, providing continuous resistance throughout its thickness.
Q
How does the built-in vapor barrier reduce pipe corrosion?
By preventing moisture penetration continuously, the system prevents water from reaching the pipe surface. This greatly extends the system's life and significantly reduces the risk of corrosion under insulation.
Q
Do I need fiber materials for expansion joints?
No, unlike conventional rigid foam LNG pipes, this flexible system does not require the use of fiber materials as expansion and contraction fillers.
Q
How does the system handle longitudinal expansion and contraction?
The material possesses elasticity at low temperatures, which naturally accommodates expansion and shrinkage in the longitudinal direction.
Q
What is the recommended installation method to resolve expansion joint issues?
It only requires installing the low-temperature elastomeric material in each layer according to the recommended reserved length to solve expansion joint problems.
