Kingflex flexible ULT insulation system does not need to install moisture barrier. Due to the unique closed cell structure and polymer blend formulation, LT low temperature elastomeric materials have been highly resistant to water vapor permeation. This foamed material provides continuous resistance to moisture penetration throughout the thickness of the product.
This feature of the product greatly extends the life of the entire cold insulation system and significantly reduces the risk of corrosion of the pipes under the insulation.
Build in expansion joint
Kingflex flexible ULT insulation system does not require the use of fiber materials as expansion and expansion fillers. (This type of construction method is typical on rigid foam LNG pipes.)
On the contrary, it is only necessary to install the low temperature elastomeric material in each layer according to the recommended reserved length to solve the expansion joint problem required by the conventional system. The elasticity at low temperatures gives the material the characteristics of expansion and shrinkage in the longitudinal direction.
Frequently Asked Questions
Q1: Does the flexible ULT insulation system require an additional moisture barrier?
A1: No, the system does not require the installation of an external moisture barrier. Its unique closed-cell structure and polymer blend formulation make it highly resistant to water vapor permeation.
Q2: How does the LT elastomeric material resist water vapor?
A2: The LT low-temperature elastomeric material is a foamed material that provides continuous resistance to moisture penetration throughout the entire thickness of the product.
Q3: How does the built-in vapor barrier benefit the pipes?
A3: By preventing moisture penetration, it significantly extends the service life of the entire cold insulation system and reduces the risk of corrosion of the pipes under the insulation.
Q4: Are fiber materials required as expansion fillers for the joints?
A4: No, unlike rigid foam LNG pipes, this flexible ULT insulation system does not require the use of fiber materials as expansion fillers.
Q5: How does the system solve expansion and contraction issues at low temperatures?
A5: It only requires installing the low-temperature elastomeric material in each layer according to the recommended reserved length. The elasticity at low temperatures naturally handles expansion and shrinkage in the longitudinal direction.
