LNG Carrier Containment Insulation Line in China

LNG Carrier Containment Insulation Line Project in China

Cryogenic PU Insulation Development project reference: Three-stream material preparation, metering and mixing for the specified cryogenic insulation formulation and casting process.

Project Reference and Configuration

Illustration notice. Process illustrations are not verified photographs of this installation.

Project reference basis. Figures and configuration details are reported in the supplied project brief. They are reference values for the stated application, rather than verified acceptance results or a guarantee for another installation. Confirm the source records, material, tooling, operating schedule and test method when assessing a comparable project.

This project reference describes three-stream material preparation, metering and mixing for the specified cryogenic insulation formulation and casting process.

Configuration and numerical values are reproduced from the supplied project brief for discussion. Original production, inspection and acceptance records have not been verified; these values do not establish certification or performance for another configuration.

Equipment References in the Project Brief

The supplied brief lists the following equipment references. Model identities, quantities and the actual delivery scope follow the original equipment schedule.

1. Three-Component Cryogenic Metering Machine: Primary chemical degassing, servo metering, and low-exotherm dynamic mixing.
2. Low-Shear Water-Jacketed Mixing Head: Water-cooled helical rotor head keeping peak exotherms strictly below 95°C.
3. Cryogenic Plywood Box Mold Conveyor: Temperature-controlled roller conveyor holding tool boxes at 40°C ± 1°C.
4. Liquid Nitrogen Thermal Shock Test Bay: Cryogenic test chamber validating -196°C liquid nitrogen immersion survival.

Installation, training, warranty and service arrangements follow the project agreement; durations in this brief are references.

Project Reference Values

−196°C

Reference: Liquid-Nitrogen Test

Project-brief reference; original records pending. The brief lists a liquid-nitrogen exposure result. Specimen, duration, failure criteria and original records are pending; short thermal-shock exposure does not establish continuous LNG-service suitability.

<92°C

Reference: Reaction-Exotherm

Project-brief reference; original records pending. The brief lists a peak reaction-core temperature below 92°C. Confirm formulation, cast volume, sensor positions and original temperature records; it does not establish absence of internal cracking.

135 MPa

Reference: Compressive-Modulus

Project-brief reference; original records pending. The brief lists 135 MPa at −163°C. Confirm the material, specimen and method. This material-test reference does not establish vessel-system approval or a general structural load rating.
