HL's Vacuum Insulated Pipe (VIP) is built to ASME B31.3 Pressure Piping code as the standard.
HL is a vacuum manufacturer. All raw materials are purchased from qualified suppliers. HL can purchase raw materials which are specified standards and requirements according to customer. Usually, ASTM/ASME 300 Series Stainless Steel (Acid Pickling、Mechanical Polishing、Bright Annealing and Electro Polishing).
The size and design pressure of the inner pipe shall be according to the customer's requirements. The size of the outer pipe shall be according to the HL standard (or according to the customer's requirements).
Compared with the conventional piping insulation, the static vacuum system offers better insulation effect, saving gasification loss for customers. It is also more economical than the dynamic VI system and reduces the initial investment cost of the projects.
The advantage of the Dynamic Vacuum System is that its vacuum degree is more stable and does not decrease with time and reduces the maintenance work in the future. Especially, VI Piping and VI Flexible Hose are installed in the floor interlayer, the space is too small to maintain. So, the Dynamic Vacuum System is the best choice.
