What is a Loading Arm?
A loading arm is a pipe device used in the petroleum industry, chemical industry, ports, etc., for liquid loading and unloading. It features mobility, telescopic flexibility, high safety, and sensitivity.

Applications and Characteristics
Primarily used in fluid loading/unloading processes within the petrochemical industry, also known as a "fluid loading arm."
Constructed with swivel joints, rigid pipes, and elbow connections to enable the transfer of liquid media between railway/road tank cars and terminal storage pipelines. It replaces outdated hose connections and serves as an ideal specialized equipment in fluid loading/unloading processes.
Applicable in the chemical industry and other sectors for loading/unloading various liquid raw materials.
Structural Composition
A loading arm mainly consists of fixed, slewing, operating, balancing mechanisms, and oil pipelines, including:
Swivel joints: Precision-manufactured from forged steel or aluminum alloy, equipped with double-row ball bearings and special stainless steel seals. Features flexible rotation, reliable sealing, and long durability.
Balancing systems: Available in counterweight, torsion spring, compression spring, tension spring, screw-driven, hydraulic, or pneumatic balancing types, all operable with minimal force.
