Compared to conventional foam-insulated pipes, using VIP saves time and resources: with a heat input of 3 W/m2, vacuum insulation is many times more effective compared to conventional insulation materials (stone wool or cellular glass insulation), while installation at the construction site is faster and the service life of the pipe is longer. The cost-efficient transfer of liquid natural gas and liquid hydrogen LH2 (LNG) requires piping systems in much larger dimensions than is the case for other cryogenic liquids. Smaller pipe diameters can be selected so that the cost of materials can be reduced.
"Our proprietary technology enables flow rates of 6 000 m3/h with nominal diameters of up to DN 1 000. We also ensure a heat input of <3 W/m2 for these sizes," Norbert Heinzle explains and adds: "Currently, more than approx. 3 000 metres of VIP transfer lines including cryogenic valves for the international and national market of SCHWANNER – our affiliated company in Burgkirchen – are planned, manufactured and shipped from Burgkirchen every year."
You too can be there when the VIP is presented on Tuesday, 27 September from 12:30 p.m. at the SSW Conference in Maastricht, Netherlands. More detailed information is available here: Stainless Steel World Conference & Expo 2022 – Conference & Expo
SCHWANNER has been producing vacuum-insulated transfer systems for cryogenic liquids since 1984, and in 1990 the company started producing cryogenic valves. Engineering, material testing, installation, documentation and service are also provided. The family business has been part of the BUTTING Group since 2021.
