PLUG INSTALLATION STRUCTURE OF SEALED HEAT-INSULATING TANK

摘要

The present invention relates to a plug installation structure of a sealed heat-insulating tank capable of minimizing a change in design of a primary heat-insulating panel while efficiently reinforcing a structure having the local weak strength caused by a space between the primary heat-insulating panels by producing a plywood, filling the space between the primary heat-insulating panels (primary boxes), into a double plate structure of the form of a plug.;COPYRIGHT KIPO 2018
