Integrated LNG Cryogenic Pump Skid System Design

Heavy-Duty Skid Structure
The carbon steel skid frame is engineered for transportation stability, equipment alignment and long-term outdoor operation. Protective coating systems are applied according to project requirements for harsh environments.

Cryogenic Pumping Unit
We provide submerged cryogenic pumps and canned motor pump configurations designed for stable LNG transfer performance with low NPSHr characteristics to reduce cavitation risks.

Vacuum Insulated Cryogenic Piping
Cryogenic piping systems use stainless steel materials combined with vacuum insulation technology to minimize heat transfer, reduce LNG evaporation and improve energy efficiency.

Automated Control & Safety System
Integrated PLC-based control systems monitor and regulate:
Flow rate
Pressure
Temperature
Liquid level
Pump operation status

Manufacturing Process

Engineering & Design Review: 3D P&ID and layout design using SolidWorks/SmartPlant, followed by client approval and finite element analysis (FEA).

Material Procurement & Inspection: Traceable 3.1 certified stainless steel materials, valves, and electrical components.

Piping & Frame Fabrication: Precision CNC pipe cutting, orbital welding, and structural frame fabrication.

Surface Treatment & Coating: Shot blasting followed by multi-layer anti-corrosion marine epoxy or polyurethane painting.

Component Integration: Mounting pumps, vacuum-insulated lines, instrumentation, safety valves, and electrical control panels.

Cryogenic & Factory Acceptance Testing (FAT): Nitrogen purging, hydrostatic/pneumatic testing, helium leak testing, and cold performance testing.

Final Sign-off: Client or third-party inspector (TÜV, SGS, BV) sign-off and documentation compilation.

Quality Control & Testing

01/

Non-Destructive Testing (NDT): 100% Radiographic Testing (RT) or Ultrasonic Testing (UT) on critical pressure welds, along with Dye Penetrant Testing (PT).

02/

Pressure & Leak Testing: Hydrostatic testing up to 1.5x design pressure, followed by high-sensitivity Helium Leak Detection on vacuum lines.

03/

Cryogenic Liquid Nitrogen Functional Testing: Full operational cold-testing using liquid nitrogen to verify thermal shrinkage, pump alignment, seal integrity, and flow rates under actual cryogenic conditions.

04/

Electrical & Automation FAT: Factory Acceptance Testing (FAT) covering safety loop interlocks, emergency shutdowns, and instrument calibration.

Packaging & Delivery

Export-Grade Protection

Heavy-duty wooden crates or steel-frame packaging designed for ocean freight and rough overland transit.
