Are the quick connectors or flanges more common for loading and unloading LNG tankers? Is it very troublesome to replace the quick-connect male connector?
Currently, the loading and unloading of LNG tankers almost always relies on flange connections
The connection port of the tank truck is usually a quick-connect type for linking to the tank truck itself, while connections to the unloading pipelines are typically made using flanges. The LNG loading arm is connected to the tank truck via flanges, and corrugated hoses can generally be connected either through flange ports or quick-connect fittings
Thank you, teacher! As far as I know, quick connectors are also safe and reliable; it’s just that they aren’t widely used, so the male connectors at storage and transportation stations where quick connectors aren’t needed have to be removed. But overall, efficiency should still be improved. But why is no one willing to use it?
Thank you, teacher! Could you share your experience with the quick connection trial? What specific issues did you encounter?
Fast connections are often used in low-temperature applications, but it can be problematic when the sizes of these fast connections differ from those specified for the storage tanks. In such cases, the fast connections are removed; it’s better if the flanges don’t match either. Tank trucks come equipped with flange adapters that allow for adjustments to different pipe diameters
On one hand, domestic quick-connect fittings may not yet be fully developed; it might be worth trying imported brands, as they are likely to be more advanced in this area compared to those in China. After all, the cleanliness standards in foreign chemical plants and similar facilities are much higher than those in China, and this is achieved thanks to the splash-proof, leak-free, and highly airtight properties of these quick-connect fittings. Brands such as German Walther-Praezision and American PARKER are worth considering.
The issue of matching flanges for quick connection should be easy to resolve; the key question is whether frequent disassembly increases the workload for the operators involved, as well as what requirements there are in terms of operation. Also, just before frost forms, will thawing increase the refilling efficiency?

The loading and unloading of LNG tankers is almost always done via flange connections. I work in the field of quick-connect fittings; there was a lot of foreign trade in this area before, and just as in the mobile phone market here, I think the trend will continue to be toward quick-connect solutions. There are also flange quick-connect adapters that can fill this gap. Quick connection is more convenient compared to flange connections
They are mostly flanges, and are widely used in quick-connect industrial gas tankers
