Marine loading arm is the special equipment for loading/unloading fluid materials crossing over the wharf and tanker, with swivel joints connecting pipelines, assist by a supporting structure, including other accessories such as control systems required by customers.
At present, the marine loading/unloading arms has many structural forms in such series as AM61, AM62, AM63 and AM64.
According to the difference in physical and chemical features and temperature of the transmission medium of the loading/unloading arms as well as special requirements of customers, the arms can be designed in many pipe forms such as carbon steel, stainless steel and heat tracing, with temperature range being -196~250℃, the maximum design pressure 10Mpa and nominal pipe size DN80~DN600 (3”~24”). The operating mode can be designed as manual or electro-hydraulic control type in accordance with caliber, model and load of the loading/unloading arms and the customer requirements. During the fluid transmission process, the arm can move with the tanker within the normal drift range of the latter. It can also be set with an acoustic-optical alarm device, thereby providing acoustic-optical alarm through travel monitoring system in case header pipe of the tank drifts beyond the specified operating scope.
Marine loading arm is comprised of: pipeline, plumbing accessories, swivel joint, balancing assembly, supporting structure and operating system.
