MLA可以分为单管型和双管型（配备气项回气臂）。 单管型MLA的尺寸为6英寸至16英寸（DN150至DN400），双管型MLA的尺寸为6英寸+ 3英寸，8英寸+ 4英寸，10英寸+ 6英寸，12英寸 + 8英寸，14英寸+ 8英寸及其他定制尺寸。
ERC有两种类型，一种是单油缸型，另一种是双油缸型。 ERC的设计完全符合OCIMF标准。 单油缸型ERC由双球阀（DBV）和一个油缸组成，当报警激活时，气缸将驱动双球阀闭合并打开ERC抱箍。两段式ERC由双球阀（DBV）和两个气缸组成。首次报警时，DBV将由PLC控制的气缸关闭。当第二次报警时，ERC箍将由通过PLC控制的气缸打开。
江苏长隆石化装备有限公司成立于2011年，我公司的创始人兼总工程师冯是公先生是中国第一台船用卸料臂的发明者，他在液体装卸行业拥有20多年的经验。 我们公司拥有40多种专利，包括LNG MLA，ERC，QCDC专利。我们的船用装卸臂的年生产力达到每年100台套以上。 我们在中国总共为19个LNG接收站提供过LNG计量装卸车撬，计量装卸系统，计量装卸车臂等产品。 2020年，中海油从CCLPEC购买了第一套中国制造的16寸LNG船用卸料臂。2019年，CCLPEC与意大利品牌MIB签署了战略合作协议，以为客户提供更具性价比的MLA。

Types of Marine Loading Arm:
Marine loading arm can be divided into two type: standard type and piggy-back type. The piggy-back marine loading arm has liquid arm and vapor return arm.
The Difference Between Marine Loading Arm and Marine Loading Hose:
Marine loading arm is construted by rigid pipe, has long service life, can achieved autometic docking.
Marine loading arm
Marine loading hose
Around 25 years
Around 5 years
Operation assistant equipment
Do not needed, HPU hydraulic-electrical operated
Hose crane is needed
Equipped with nitrogen purging system and vapor recovery system
Frequent disassembly leads to inevitable leakage
Rigid pipes make the whole structure more reliable
Damage can be caused by negative pressure
Marine loading arm can be easily operated by one worker
Difficult for workers to carry, need to be lifted by hose crane
Marine Loading Arm Material:
The material of marine loading arm is selected according to the liquid/gas that need to be loaded. Normally, for non-corrosive medium with room temperature, carbon steel is competent. For corrosive liquid or cryogenic liquid, the main pipeline is recommended to use SS316 and SS304.
