We just pulled off a major milestone at HL Cryogenics: delivering more than 600 meters of high-performance DN200 Vacuum Insulated Pipe for a big LNG project in Brazil. This isn’t just a win for us—it shows we’ve got the muscle and know-how to handle tough, global projects. Our team takes pride in building cryogenic piping that stands up to the extreme demands of international liquefied gas distribution. For this project, we teamed up with Furui Special Equipment and used top-quality Stainless Steel 304. That choice wasn’t random—it’s about making sure the pipes last, hold up under freezing temperatures, and don’t lose their strength, even stretched out over 600 meters.
Our Vacuum Insulated Pipe relies on advanced vacuum insulation. It's a double-walled setup: the inner pipe moves the cryogenic fluid, the outer one keeps the vacuum tight. Add in our Dynamic Vacuum Pump System and you get a powerful vacuum that basically wipes out heat transfer—no convection, no conduction. The result? Minimal heat leaks and top-tier thermal efficiency for transferring LNG or handling any other cryogenic job.
But we’re not just about rigid piping. Our Vacuum Insulated Flexible Hose handles tricky layouts—it bends, absorbs vibration, and deals with thermal contraction, all while keeping the vacuum seal solid. Every hose goes through strict pressure and helium leak tests, so you know it’s safe and up to code, no matter where it ships.
To help liquefied gases flow even better, we build in Vacuum Insulated Valves and Phase Separators. The valve gives you laser-precise control with almost no added thermal mass, so you don’t get gas pockets messing things up. The phase separator is a game-changer for LN₂ systems in labs and semiconductor plants: it strips out vapor and delivers pure, saturated liquid right where you need it.
For smaller storage and distribution, our Mini Tank solutions step in. They’re perfect for holding liquid nitrogen or oxygen, fitting seamlessly into bigger cryogenic networks.
We know engineers and project managers care about reliability above all, so we engineer every detail for technical depth. Our pipes use internal expansion bellows and custom supports to handle the wild temperature swings in LNG or liquid argon transfer. Multi-layer super insulation inside the vacuum space takes care of radiation heat, so performance stays high.
Whether it’s a hospital’s oxygen supply, an aerospace test, or a full-scale LNG terminal, we build our Vacuum Insulated Pipes and Valves to run maintenance-free for the long haul. Our Dynamic Vacuum Pump System lets you keep an eye on vacuum levels in real time, so the system stays efficient, year after year.
From ultra-pure LN₂ lines in chip factories to the brutal testing rigs in the auto industry, our hoses and pipes deliver the safety and performance that top sectors demand. Brazil proved we can handle huge, complex projects anywhere in the world—manufacturing, shipping, and installing without missing a beat.
We’re all in on building a more efficient, sustainable energy infrastructure. Solutions like our Phase Separator and Mini Tank units are just part of that bigger picture. If you’re looking for a custom cryogenic setup that won’t let you down, let’s talk. HL Cryogenics is ready to help make your next liquefied gas project a success.
