Heat Exchanger Tubes

Heat Exchanger Tubes are used in a wide variety of industrial liquid to liquid and gas to gas applications. They are often chosen for their strength, corrosion resistance and high thermal conductivity. The tubes are usually made of metals such as carbon steel, stainless steel or nickel alloys or non-ferrous copper alloys. Other materials such as Hastelloy and Inconel are also used for specific applications requiring high temperatures or resistance to chemical abrasion. The size of the tube is chosen based on the flow rate, inlet and outlet temperature and pressure levels, as well as physical properties of the substances being processed. This information is used by the manufacturer to engineer a shell and tube heat exchanger to meet the application requirements.

Inconel 625 Pipe: A Versatile Alloy for High-Temperature and Corrosive Environments

During operation, the heat transfer tubes experience many stresses and vibrations. This can cause cracks or a loss of pressure between the shell- and tube side. To prevent these risks, baffles are installed on the shell-side of the heat transfer tubes. These help enhance the fluid velocity, force it to cross the tubes according to a specified path and improve the heat transfer efficiency. They also help to reduce the formation of unwanted material on the heat transfer surfaces and the subsequent fouling.

Another way to increase the efficiency of a shell and tube heat exchanger is by using a floating head design. This is where the tube sheet at the rear header end (tube side fluid inlet) is not welded to the shell but allowed to float. This allows for thermal expansion and also makes it easier to dismantle the heat exchanger and inspect the tubes and the inside of the shell.

The Chevrolet Equinox EV for 2025

 

The Chevrolet Equinox EV is a comfortable, spacious small electric SUV with good looks and enough range for many commutes. It costs less than most competitors and still qualifies for a $7,500 federal tax credit. That, combined with GM’s aggressive sales push, makes the Equinox EV a strong contender in its segment.

2025 Equinox EV performance has ditched the 2LT and 3LT trim levels in favor of a simpler duo of LT and RS models with optional packages. Fully equipped, a base LT can run north of $46,000. Adding the Convenience package adds a power driver’s seat, heated front seats and a 360-degree camera, among other niceties.

The exterior design is slick and contemporary, and features a sculpted brow line where the hood meets the rest of the car’s body. It’s complemented by a slim LED light bar that creates a unique mustache shape, as well as crisp body creases and flush door handles. A pair of elongated A-pillars contribute to the wide stance.

2025 Equinox EV Review: Is This Chevy’s Best Electric SUV Yet?

Cargo room is ample, and the rear seats fold flat to expand it further. A power liftgate is available as an option, and a hands-free trunk opens with the press of a button. Adaptive cruise control is standard and does a great job of maintaining speed and anticipating needing to brake on the highway. Super Cruise hands-free driving is also available.

Inside, a massive 17-inch infotainment display is a real standout feature, and the Equinox EV’s interior is comfortable and quiet. However, GM’s hubris in spurning Apple CarPlay and Android Auto is hard to overlook.…
