Swivel Joints Technology Explained
Swivel Joints are key components for the transportation of liquids and gases for a wide range of industries
Swivel Joints – Basic Working Principles
Whether you work in the chemical, petrochemical, or oil and gas industries, among others, swivel joints are key components. They guarantee smooth transportation of liquids and gases between fixed piping and movable equipment.
Swivel joints also play an essential role in hose reels, piping systems, wastewater treatment, just to name a few. Their use in loading arms provides flexibility, easy handling and maximum safety for operators.
It also sustains optimal performance under high internal pressures, traction and bending forces.
Swivel Joint D2000Which Swivel Joint Should I choose?
Swivel joints are essential elements for the loading arm industry. This industry requires, above all, components with easy handling and low-wear characteristics. At Emco Wheaton, we offer a wide range of swivel joints that will improve your operational safety and performance reliability.
Here’s a comparative list of Emco Wheaton’s swivel joint portfolio for loading arms:
Swivel Joint D2000
- Suitable for various fluid handling applications (mineral oil industry, food industry, chemical industry)
- Compact, sandwich design
- Easy to replace seals (without disassembling the whole loading arm)
- No dirt ingress into the ball track thanks to a double O-ring sealing
- High leak-proof capacity due to the smooth rotation and high bending moment capacity
- Separated bearing module allowing a standard swivel joint to operate at temperatures ranging from -60 °C to +250 °C with a max operating pressure of 580 psi (40 bar)
PTFE D2000 Swivel Joint
- Suitable for extremely aggressive products thanks to its special design
- No contact between the product and the carbon steel component as leakage goes through the leak detection port
