Build in vapor barrier 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 methid 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.Hebei Kingflex Insulation Co., Ltd is founded by Kingway Group which is established in 1979.
