Ask anyone in the engineering field about advanced thermal management in China, and HL Cryogenics always comes up as the go-to name for Vacuum Insulated Pipe and Vacuum Insulated Flexible Hose. We're not just recognized for quality; people genuinely respect our technical edge. It's something we've built up over years by getting deep into the physics of heat transfer—experimenting, refining, and innovating until our multilayer insulation and high-vacuum design perform at levels others simply can't match.
When someone comes to us, they get a full package: we handle everything from the initial thermal stress analysis to installing the final Vacuum Insulated Phase Separator. Our work isn't just about building a pipe. We're obsessed with every detail—making sure the system keeps gas out and delivers liquid as pure as possible. One of our proudest achievements is our Dynamic Vacuum Pump System. This technology isn't just a nice extra; it's absolutely vital for the kind of stability people expect in cryogenic installations that are meant to last decades. In contrast to static systems, our Dynamic Vacuum Pump System keeps working, constantly removing any outgassing molecules from the annular space so you never lose vacuum integrity. This commitment to reliability is exactly why top-tier semiconductor fabs, which demand ultra-pure liquid nitrogen, and aerospace facilities with extreme pressure cycles, both trust us.

● Advanced Thermal Insulation
But that's just the start. Our Vacuum Insulated Valve designs are crafted to prevent heat bridging—nobody wants frost or operational hiccups at the control points, especially when the stakes are as high as they are in medical imaging or LNG terminals. The medical sector relies on our integrated systems for MRI cooling, knowing that we're up to international safety standards like ASME and CE. When we take on the challenge of LNG terminals, where the transfer of liquefied natural gas must happen safely with minimal flash gas, our heavy-duty cryogenic pipes and hoses are ready for the job.
● Active Vacuum Management
By combining our Dynamic Vacuum Pump System, Vacuum Insulated Valve, and Phase Separator, we give you a setup that moves liquid helium efficiently and keeps costs down. Our Mini Tanks and Flexible Hoses let us handle both mobile and fixed jobs with precision.
We've also mastered the integration of Mini Tanks in vacuum networks, connecting them with zero-leak, high-performance pipes directly to their application point. And honestly, whether we're delivering a standard cryogenic hose or engineering a super-complex Vacuum Insulated Phase Separator for a sprawling industrial facility, we never cut corners on materials. SS316L is our metal of choice for pipes and hoses—a deliberate decision, because we want every client to have equipment that lasts and withstands whatever chemicals they use. Our team is hands-on from the first weld to the final vacuum seal, making sure everything completes the closed-loop efficiency—Dynamic Vacuum Pump System, Vacuum Insulated Valve, and Phase Separator—all working together to drive boil-off losses down.
● Operational Safety Managed by Valve and Valve Box
Every component is tested and reinforced. Our Vacuum Insulated Valve assemblies are put through bubble-tight seal tests to guarantee leak-proof results. Cryogenic hose products get extra attention—built tough, so they hold up under heavy, everyday industrial handling.
● Precision Flow & Phase Control
When you select HL Cryogenics, you're choosing a partner who will actively maintain your cryogenic system. We customize Vacuum Insulated Flexible Hose and Phase Separators for whatever space or configuration your facility needs—small labs, massive LNG terminals, you name it. It's a level of care and precision that defines our place at the top in China's thermal management sector. We see a Vacuum Insulated Pipe as more than a piece of hardware—it's the backbone of your operation, and we treat it that way.
If you want pipes and vacuum-jacketed solutions that truly deliver, reach out to our technical team. We'll walk you through options and design solutions that fit your exact requirements. Let us show you why HL Cryogenics is known globally as the definitive source for high-performance cryogenic and vacuum-insulated engineering.

HL Cryogenics' Vacuum Insulated Pipe (VIP) is manufactured in accordance with the ASME B31.3 Pressure Piping Code as our standard.
HL Cryogenics is a specialized vacuum equipment manufacturer, sourcing all raw materials exclusively from qualified suppliers. We can procure materials that meet specific standards and requirements as requested by customers. Our typical material selection includes ASTM/ASME 300 Series Stainless Steel with surface treatments such as acid pickling, mechanical polishing, bright annealing, and electro polishing.
The size and design pressure of the inner pipe are determined according to the customer's requirements. The size of the outer pipe follows HL Cryogenics' standard specifications, unless otherwise specified by the customer.
Compared with conventional piping insulation, the static vacuum system provides superior thermal insulation, reducing gasification losses for customers. It is also more cost-effective than a dynamic VI system, lowering the initial investment required for projects.
