Marine loading arm is the special equipment for loading/unloading fluid materials crossing over the jetty and tanker, with swivel joints connecting pipelines, assisted 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 -196~250ºC, 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 dimension, 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 a visual sound alarm device, thereby providing visual sound 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 etc.

AM62 Structure Features
A part of the product pipe provides support to the loading arm, but most weight and loads are supported by an independent body or supporting auxiliary supporting organizations. Inner and outer arms share one counterweight system. Mixed mode support for single-tube loading arms are compactly structured, suitable for large-tonnage vessels.

Frequently Asked Questions
What are the main applications of the AM64 marine loading arm?
It is specifically designed for high-efficiency loading and unloading of fluid materials, including solids, liquids, and gases, between jetties and tankers.
What temperature ranges can this equipment withstand?
The equipment is engineered to operate in extreme environments ranging from -196ºC to 250ºC, making it suitable for both cryogenic and high-temperature media.
What materials are available for the pipeline construction?
Depending on the medium's chemical properties, we offer carbon steel, stainless steel, and options with heat tracing for specific industrial needs.
How is the marine loading arm controlled?
We offer both manual and electro-hydraulic control systems to match the specific dimensions, load requirements, and operational preferences of the client.
What safety features are integrated into the system?
The systems can include travel monitoring with visual and sound alarms to notify operators if the tank header pipe drifts beyond safe operating limits.
What pipe sizes are commonly supported?
Standard nominal pipe sizes range from DN80 to DN600 (3 inches to 24 inches), with specialized specifications available upon request.
