The Vacuum Insulated Transfer Lines (LH2 VIP) are Demaco pipes for transferring liquid hydrogen between storage vessels, production sites, applications, and transport vehicles. They operate with liquid hydrogen at -252.9°C and use double-wall stainless-steel construction with high-vacuum insulation to reduce heat transfer into the cryogenic process line. The design supports process-line diameters up to 8 inches and a standard design pressure up to PN25. The exact product page describes the transfer line as a rigid, slim stainless-steel pipe with prefabricated sections, with the vacuum space formed between the two walls and spacers preventing wall contact. Application examples include connections between storage and end-use equipment and between production locations and transportation vehicles, with use in energy, mobility, and other liquid-hydrogen projects. The product page also states suitability for both liquid hydrogen and LNG, subject to the applicable requirements for the intended medium.
