液化石油气罐主要用于海上液化石油气的运输,主要是将丙烷加压液化成液体,可在常温下进行装卸,这种运输船也叫全加压式液化石油气船,其货舱常为球形或圆柱形罐。在长江沿岸通常将运输船在岸边制作,同时在船体适当位置制作液化气罐,罐体厚度一般大于140mm,通常每条运输船船罐容积在5000m~3以上,每个船罐重量在450t以上,因此体积和重量都较大。由于运输船和船罐在陆地上分别制作,所以需用大型履带起重机整体吊装至船舱内安装。根据长江沿岸船厂的特殊地理位置,
Liquefied petroleum gas tanks are mainly used for the transportation of liquefied petroleum gas at sea. The liquefied petroleum gas tank is mainly used for liquefying propane into liquefied liquid at normal temperature. The liquefied petroleum gas tank is also called a fully pressurized liquefied petroleum gas tanker, Spherical or cylindrical cans. On the banks of the Yangtze River, ships are usually produced on the shore, while liquefied gas tanks are made at suitable positions on the hull. The thickness of the tank is generally more than 140mm. Usually, the capacity of each tanker is above 5000m 3 and the weight of each tanker is 450t Above, so the volume and weight are larger. As the transport vessel and the tank are separately produced on land, it is required to use a large crawler crane as a whole to be hoisted to the cabin for installation. According to the Yangtze River Shipyard’s special geographical location,
