Vacuum Insulated Pipe (VIP)

Rigid Vacuum Insulated Pipes

CSM rigid Vacuum Insulated Pipes (VIP) are engineered to deliver superior thermal efficiency and long-term reliability for the transfer of cryogenic fluids. Utilizing advanced super-insulation technology, VIP systems are suitable for a wide range of cryogens, including liquid nitrogen, oxygen, argon, helium, hydrogen, and LNG.

Each vacuum insulated pipe consists of a dual-wall stainless steel construction: an inner carrier pipe for cryogenic fluid transfer and an outer jacket that maintains a high-quality vacuum environment. The inner pipe is wrapped with multi-layer insulation (MLI) and integrated with hydrogen getters and molecular sieves to preserve long-term vacuum integrity and insulation performance. This “vacuum jacket” design significantly minimizes heat ingress, reducing thermal losses and improving overall system efficiency.

Key Features and Benefits

Superior Vacuum Insulation: Effectively minimizes heat loss and product boil-off, lowering operating costs while maximizing thermal efficiency
Reduced Cool-Down Losses: Lightweight construction with low heat mass shortens cool-down times during startup and reduces product loss during maintenance or system downtime
Frost and Condensation-Free Connections: Precision-engineered bayonet connections and super-insulated field-welded joints ensure frost-free, condensation-free operation for long-term reliability
Ease of Integration: Pre-engineered modular spool designs simplify installation, reduce site work, and streamline maintenance
10-year Vacuum Warranty: Industry-leading vacuum warranty ensures confidence, durability, and long-term performance

Configuration & Flexibility

CSM Rigid Vacuum Insulated Pipes are available in sizes ranging from ½” to 12” NPS, with lengths of up to 12 meters (40 ft). Options include internal or external expansion joints and a wide variety of end connections, such as bayonets, vacuum- or foam-insulated field-welded joints, flanges, threaded connections, flared fittings, and custom interfaces. For added system flexibility, integrated flex sections can be incorporated to accommodate thermal expansion, offsets, expansion loops, and use-point transitions.
