HL Cryogenics has been a trusted leader in the cryogenic equipment industry for over 30 years. Through extensive international project collaborations, the company has developed its own Enterprise Standard and Enterprise Quality Management System, aligned with global best practices for Vacuum Insulation Cryogenic Piping Systems, including Vacuum Insulated Pipes (VIPs), Vacuum Insulated Hoses (VIHs), and Vacuum Insulated Valves.
The quality management system includes a Quality Manual, dozens of Procedure Documents, Operation Instructions, and Administrative Rules, all updated regularly to meet the evolving demands of vacuum insulation cryogenic systems in LNG, industrial gases, biopharma, and scientific research applications.
HL Cryogenics holds ISO 9001 Quality Management System Certification, with timely renewals to ensure compliance. The company has earned ASME qualifications for Welders, Welding Procedure Specifications (WPS), and Non-destructive Inspection, along with full ASME Quality System Certification. Additionally, HL Cryogenics is certified with the CE Marking under the PED (Pressure Equipment Directive), ensuring its products meet stringent European standards.
Leading international gas companies—including Air Liquide, Linde, Air Products (AP), Messer, and BOC—have conducted on-site audits and authorized HL Cryogenics to manufacture in accordance with their technical standards. This recognition demonstrates that the company’s Vacuum Insulated Pipes, hoses, and valves meet or exceed international cryogenic equipment quality benchmarks.
With decades of technical expertise and continuous improvement, HL Cryogenics has built an effective quality assurance framework covering product design, manufacturing, inspection, and post-service support. Every stage is planned, documented, evaluated, assessed, and recorded, with clearly defined responsibilities and full traceability—delivering consistent performance and reliability for every project, from LNG plants to advanced laboratory cryogenics.
