LOADING ARMS
Loading Arms
Our high-performance industrial loading arms provide safe, emission-free, and high-throughput fluid transfer for road tankers, railcars, and marine vessels. Built to replace hazardous flexible hose systems, our articulated rigid piping systems feature precision-engineered swivel joints and robust counterbalancing. They ensure effortless manual or automated operation while protecting your team and the environment.
Why Choose Our Loading Systems?
Zero Spillage: Integrated dry-disconnect couplers and Emergency Release Systems (ERS) eliminate product loss.
Effortless Handling: Smooth mechanical spring cylinders or counterweight systems reduce operator fatigue.
Regulatory Compliance: Engineered to meet strict ASME B31.3, API, and environmental vapor emission standards.
Extreme Durability: Heavy-duty construction withstands high pressures, cryogenic temperatures, and corrosive media.

*Note: Maximum flow rates are calculated based on a safe liquid velocity of 4.5 m/s to prevent static buildup. Actual flow rates may vary depending on fluid viscosity and system pressure drops.
Tailored Upgrades for Your Operations
Vapor Recovery Lines: Parallel vapor return piping captures toxic or volatile organic compound (VOC) emissions.
Insulation & Heating Jackets: Electrical tracing or steam jackets prevent viscous products like bitumen or sulfur from freezing.
Overfill Prevention Sensors: Optical, cane, or float switches integrate with your control room for automatic flow shut-off.
Other Categories
Our offerings include precision-engineered assemblies and application-specific components designed in compliance with international standards and project specifications.
