Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a liquid cargo containment system in an LNG ship, in particular to a double-sided fixed angle piece used for a liquid cargo containment system in an LNG ship. Background Art
[0002] LNG carriers are internationally recognized products with high technology, high difficulty and high added value. LNG carriers are special ships used to transport liquefied gas at low temperatures of -162°C.
[0003] The containment system of the liquid cargo tank of an LNG carrier is the core technology of the LNG carrier. The main function of the liquid cargo containment system is to store LNG cargo with a liquid temperature of -162°C.
[0004] The liquid cargo containment system is the isolation barrier and thermal insulation system of the liquid cargo tank, in which the liquid cargo tank is composed of two layers of insulation, primary and secondary, and two corresponding protective films. The insulation layer is composed of multiple insulation boxes, and the protective film is an invar material called "unchanged steel". The primary and secondary insulation layers play an effective role in heat insulation to maintain the temperature of the cargo in the tank during transportation. Ammonia is filled in during normal loading to ensure safety. In addition, there is a liquid dome and a gas dome, which are used for loading and unloading LNG cargo and recycling of volatile gases respectively.
[0005] The liquid cargo containment system has two main functions:
[0006] 1. Completely dense metal film ensures no leakage of LNG;
[0007] 2. Good thermal insulation capability to prevent the hull from being cooled and losing strength and toughness;
[0008] However, when the insulating plate of the current LNG ship's in-vessel liquid cargo containment system is attached to the inner wall of the LNG ship's in-vessel liquid cargo containment system, it is easy to fall off, thereby causing an unstable connection.
[0009] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
