Vacuum Insulated Pipe (VIP) systems are essential for safely and efficiently transferring cryogenic liquids like liquid nitrogen, oxygen, and argon. The choice of material here isn’t just a box to tick—it’s the backbone of system durability, corrosion resistance, and thermal performance. In practice, stainless steel 304 and 316 are the go-to materials for these applications, whether we’re talking about Vacuum Insulated Pipes (VIPs), Vacuum Insulated Hoses (VIHs), Vacuum Insulated Valves or Phase Separators. These grades are trusted across industrial, laboratory, and scientific environments for a reason.
Stainless steel 304 is widely adopted in vacuum insulated piping because it combines solid corrosion resistance with mechanical strength and maintains structural integrity at cryogenic temperatures. That’s a must-have when you’re dealing with rapid temperature swings and the demands of LIN (liquid nitrogen) transfer through both rigid pipes and flexible hoses. On top of that, it’s relatively easy to fabricate and weld, streamlining both installation and long-term maintenance. For sectors where cleanliness is critical—think pharmaceutical or food processing—304 stainless meets the required purity standards, ensuring compatibility with sensitive applications.
If you need extra protection, especially against chlorides or harsh chemicals, stainless steel 316 steps in. It takes everything 304 offers and adds a higher level of corrosion resistance, which is particularly valuable in coastal settings or heavy-duty chemical processing. In Vacuum Insulated Pipe (VIP) systems, 316 ensures longevity and reliability, even under continuous cryogenic operation or in demanding environments like LNG facilities or precision research labs. Basically, if system failure isn’t an option, 316 provides that extra insurance.
At HL Cryogenics, we manufacture our Vacuum Insulated Pipes (VIPs), Vacuum Insulated Hoses (VIHs), Valves, and Phase Separators from high-grade stainless steel 304 or 316—always chosen to match the specific requirements of each project. This selection minimizes heat ingress, cuts down on LIN boil-off, and drives up energy efficiency. Our products deliver safe, reliable, and precise cryogenic liquid transfer, whether you need straightforward piping, flexible layouts, or integrated phase separators. With the right stainless steel and our technical expertise, clients receive robust, high-performance vacuum insulated piping solutions designed for long-term success in any cryogenic application.
