BUTTING CryoTech

The Butting CryoTech GmbH is the global leader in vacuum insulated piping (VIP) for the transfer of cryogenic liquids (LNG, LH2, LO2, LN2, LHe, LAr) serving the oil & gas, automotive, and research sectors. Founded in 1899, BUTTING CryoTech stands for tradition, precision, and innovation. After starting VIP production in 1984, the first cryo valves were manufactured in 1990. BUTTING CryoTech`s cryogenic vacuumtechnology - 50 000 m VIP since 1984 and 25 000 cryo valves since 1990: I. LNG VIP: The cost efficient transport of liquid natural gas (LNG) requires transfer systems of much larger dimensions compared to all other common cryogenic liquids. Our proprietary technology enables flow rates of >200,000 ft3/h (6000 m3/h) at inner diameters up to 40" (DN1000), while ensuring a heat ingress <2.5 W/m2. II. Standard VIP: Our vacuum insulated piping (VIP) combines vacuum and multi-layer insulation for minimal heat ingress (<2.5 W/m2) and maximal efficiency to transport cryogenic liquids. In addition to standard vacuum insulated piping (VIP), transfer systems for trailers (helium & hydrogen), hydrogen systems for the automotive industry, fueling systems for aerospace (hydrogen & oxygen), and tailor-made components (e.g. neon storage tanks) are core competencies. III. Cryo valves: The introduction of valves into vacuum insulated piping (VIP) requires perfect integration into the insulation system. Schwanner accomplishes this either via welded or flange couplings, which guarantees loss-free connections with lowest possible boil-off rates.
