ASME B31.3 and PED Define Different Parts of VJ Piping Compliance
Vacuum-jacketed piping is not governed by one universal standard. For many industrial projects, ASME B31.3 defines the design and fabrication basis for the process piping, while the European Pressure Equipment Directive 2014/68/EU establishes legal conformity requirement...Read more -
The Role of Vacuum Insulated Piping in Semiconductor Manufacturing
Discover how vacuum insulated pipes, vacuum insulated hoses, and cryogenic equipment support reliable liquid nitrogen transfer and temperature control in semiconductor manufacturing. Table of Contents 1. Tempe...Read more -
Engineering Basis for Liquid Nitrogen Cryogenic Piping Design
A liquid nitrogen piping system must be designed around three priorities: limiting heat input, controlling pressure drop, and maintaining stable liquid delivery at the point of use. At HL Cryogenics, we treat the cryogenic pipe network as part of an integrated cryogenic ...Read more -
Engineering Guide to Cryogenic Hose Connections: Vacuum Bayonet Couplings with Clamps and Flanges
Choosing the right cryogenic hose connection isn’t just a detail—it keeps your system running efficiently and safely. At HL Cryogenics, we focus on options that actually make a difference: our vacuum bayonet couplings are available in both clamp-type and flange-type conn...Read more -
The Role of Cryogenic Equipment in the Biopharmaceutical Industry
The biopharmaceutical industry relies on precise temperature control to preserve biological materials, maintain product quality, and support increasingly sophisticated medical treatments. From biobanking and vaccine development to cell and gene therapies, many applicatio...Read more -
Vacuum Insulated Pipes for Liquid Hydrogen: Applications, Benefits and Key Considerations
Liquid hydrogen (LH₂) is used in applications where high energy density and extremely low temperatures are required, particularly in aerospace, hydrogen energy and cryogenic systems. Because liquid hydrogen boils at approximately -253°C (-423°F) at atmospheric pressure, controlling heat input du...Read more -
Optimizing Cryogenic Transfer Efficiency with Vacuum Insulated Piping
When you need reliable cryogenic transfer, a Vacuum Insulated Pipe is the go-to choice. It's built with a low-conductivity structure, reflective insulation, and a high-vacuum annular space that all work together to keep heat out. At HL Cryogenics, we design every system ...Read more -
Dynamic Vacuum System: The Future of Vacuum Insulated Piping
The Dynamic Vacuum System is revolutionizing vacuum insulated piping (VIP) applications, offering a robust solution for industries requiring precision and efficiency in cryogenic fluid transportation. This article explores the features, advantages, and applications of Dy...Read more -
Cryogenic Piping VS Vacuum Jacketed Piping for Air Separation Units (ASU)
When you’re running an air separation unit (ASU), you have two basic choices for moving around liquid oxygen (LOX), liquid nitrogen (LIN), and liquid argon (LAR): conventional cryogenic piping or vacuum jacketed piping. And honestly, while both can get the job done, they...Read more -
Cryogenic Piping System Design Guide for LNG Applications: From Storage Tank to End User Equipment
A solid LNG cryogenic piping system does more than just move liquid from the storage tank to the end-user’s equipment—it has to keep heat out, hold pressure steady, cut down on vapor formation, and handle mechanical stress without a hitch. At HL Cryogenics, we take all t...Read more -
Vacuum Jacketed Piping Maintenance: Vacuum Monitoring and Leak Detection Methods
If you want your vacuum jacketed piping to last, pay attention to the basics: keep an eye on the vacuum, look out for leaks, check the mechanics, and catch insulation issues early—before you start losing heat or product. At HL Cryogenics, we don’t just monitor the number...Read more -
The Application of Vacuum Jacketed Pipes in Aluminum Extrusion Machines
Aluminum extrusion is a temperature-sensitive manufacturing process. From billet heating to extrusion and subsequent cooling, temperature variations can have a direct impact on product quality, dimensional accuracy, and production efficiency. In extrusion systems that us...Read more
