Loading arms improve safety and efficiency by allowing liquid cargos to be transferred into trucks, railcars, vessels and barges using an articulated pipe system. Rigid pipe loading arms are generally constructed of several pipes - or legs - which are linked together with swivel joints and supported by a counterbalance. Loading arms can also be constructed of a combination of pipe and lengths of flexible hose to improve flexibility and range of motion. Dixon manufactures loading arms in 2”, 3” and 4” sizes. Custom-engineered loading arms in other sizes and configurations are also available upon request.
So, what is an actuated valve? An actuator is a mechanism that controls the positioning of the valve mechanically versus manually. These actuators are critical for ensuring that process control is automated in a consistent manner.
Hose couplings are designed to keep connections secure. Under many circumstances, you wouldn’t want a hose to suddenly detach from its connection. But sometimes you do. And that’s where a breakaway coupling comes in.
Bridges are marvels of architectural engineering that stand peacefully among us. We don’t think of them much, even when we are passing over them. But when you take a moment to realize the problems these infrastructures solve, you begin to appreciate the importance and rich history behind them.
For people who live in rural areas without access to a pressurized fire hydrant system, dry hydrants can be a lifesaver—literally. A dry hydrant allows firefighters to tap a reliable water source like a lake, pond, or stream—to fight a fire without using a traditional fire hydrant.
To put it plainly, quick disconnect couplings make your job easier. They are a fast and easy way to join pneumatic and fluid transfer lines by simplifying connections/disconnections and preventing air or fluid leakage. Pneumatic quick disconnects are used primarily to change between various tools, connecting the power source (compressor) to the tool. The system consists of two parts: the coupler (the female part) and the plug (the male part). Pneumatic couplings typically have a valve in the female half that shuts off the air supply automatically as soon as it is disconnected from a component ensuring the system stays pressurized.
Ah, but things aren’t quite that simple. Before using a quick disconnect system, there are a few questions you must address first: How do you identify the various types of pneumatic quick disconnect profiles? And how do you choose the correct quick disconnect coupling for the job at hand?
You are sitting in traffic and look over to see dusty air, roadwork signs, and power tools that sound like the roaring of a sold-out football stadium after a game-winning touchdown. You just drove past a construction site and all the equipment that inhabits it.
On February 7, 1904, a fire was reported in the John Hurston Building on West German Street just west of downtown Baltimore. As the fire progressed to neighboring buildings, fire companies from as far away as Washington, D.C., New York, and Philadelphia, PA arrived to help fight the blaze. But the firefighters from these other cities couldn’t use their equipment: The threads on their hoses didn’t match the threads on Baltimore’s hydrants. By the time the fire had died out, more than 70 city blocks and 1,500 buildings lay in ruin.
The thing about infrastructure is that most people don’t think about it unless it’s not working properly. When a bridge is closed or a roadway is under construction, if a water main bursts or a train is delayed, that’s when infrastructure gets your attention.
If there’s one potential mishap on your work site or plant that’s particularly damaging--but easy to avoid--it’s an improperly crimped hose. Ensuring a properly coupled hose assembly is critical to providing an effective fluid handling solution. Making an error measuring hose dimensions or incorrectly choosing the ferrule or sleeve will result in lost time and money. Worst-case scenarios result in injury to workers or environmental damage when a hose assembly fails as a result of being incorrectly crimped.
