Hyundai Heavy Industries (HHI) of Korea recently announced plans to develop a special welding technology for tank transport LNG liquefied natural gas in the Arctic region.
To install build the pipelines, often using two methods of pairing: the grafting with flange and coupling by welding method. The downside of this method is low labor productivity, weld quality is unstable, workers made very difficult, even easier labor insecurity and in many cases the only
