Shell and tube heat exchangers consist of a series of tubes. One set of these tubes contains the fluid that must be either heated or cooled. The second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required. A set of tubes is called the tube bundle and can be made up of several types of tubes: plain, longitudinally finned, etc. Shell and tube heat exchangers are typically used for high-pressure applications (with pressures greater than 30 bar and temperatures greater than 260°C). This is because the shell and tube heat exchangers are robust due to their shape. Features 1. Tube diameter: Using a small tube diameter makes the heat exchanger both economical and compact. However, it is more likely for the heat exchanger to foul up faster and the small size makes mechanical cleaning of the fouling difficult. 2. Tube thickness: The thickness of the wall of the tubes is usually determined to ensure: a. There is enough room for corrosion b. That flow-induced vibration has resistance c. Axial strength d. Availability of spare parts e. Hoop strength (to withstand internal tube pressure) f. Buckling strength (to withstand overpressure in the shell) 3. Tube length: heat exchangers are usually cheaper when they have a smaller shell diameter and a long tube length. Thus, typically there is an aim to make the heat exchanger as long as physically possible whilst not exceeding production capabilities. 4. Tube pitch: when designing the tubes, it is practical to ensure that the tube pitch (i.e., the centre-centre distance of adjoining tubes) is not less than 1.25 times the tubes' outside diameter. 5. Tube corrugation: this type of tubes, mainly used for the inner tubes, increases the turbulence of the fluids and the effect is very important in the heat transfer giving a better performance .

e #1 selling hookah charcoal for the European market has finally arrived here for the US market, and we're pretty excited! The CocoBrico brand has established a name for themselves by creating a series of high quality charcoal for hookah smokers in a lounge, house, or outdoors setting. The smooth cube shape pieces measure at 25mm on all 4 sides and work perfectly atop any hookah foil, or heat management devices. These coals are crafted with the use of all natural materials with a main ingredient consisting of raw coconut husks, and let it be known that no trees harmed in this process. This 1kg box contains 72 pieces of the Cocobrico cube coals, creating 24 to 36 sessions depending on your heating requirements. The European market excels in hookah manufacturing of key components like hookah stems, charcoal, and unique glass/metal accessories. This charcoal is widely used because of it's low ash content that doesn't leave you with a mess after a session, and durability as they're crafted to not split or spark after heating. The Cocobrico coals are rated as a high heat charcoal and throughout our many session with them, we were easily able to produce massive thunder clouds with maximum flavor. Make Your Session "Lit" This natural charcoal will require a single coil burner and a small amount of time in order to get the cloudy sessions we were able to achieve. Using cube shaped charcoal in most cases will only require you to light 3 pieces, and after placing them on the burner allow 9-12 minutes with a flip at the halfway mark to fully light the coal. Before removing the charcoal from the burner make sure that the coals are fully lit on all sides, this will provide you with an optimal session of flavor and clouds.To ensure the safest trip from the coal burner to the hookah bowl, we use a charcoal carrier as a place to store extra coal and prevent coal blackouts. These coals can be used outside but in high wind situations we always recommend using a bowl wind cover.
