SPI Supplies, like a lot of the rest of the world, has been calling their graphite rods "carbon rods". Putting it simply, a lot of users who are using what they call "carbon rods" have really been using graphite rods without realizing it. Since the resistivity of carbon and graphite, in general are quite different (the resistivity of carbon is much higher, typically about four times higher, but the exact resistivity will depend on the particular density of the rod), if a vacuum evaporator is configured for the resistivity associated with graphite, then it will work best on graphite and if a real carbon rod is substituted, then it will operate somewhat differently (in extreme cases, not at all). So you do want to be sure before ordering that you are indeed placing your order for the right kind of rod.

Fiberglass fishing rods appeared in the 1940s, produced as a less expensive, lighter weight, and more durable alternative to traditional bamboo rods. Swiftly gaining popularity, fiberglass rods became standard for dedicated and amateur anglers alike until the 80s. Today, fiberglass fishing rods remain popular among beginners, touted for their ability to withstand tugging, ripping, and other harsh movements typical of inexperienced anglers. Fiberglass rods also tend to be more forgiving for learners, since their mid-slow action gives the user more time to correct.

After hitting the market in the 1960s, graphite fishing rods really hit their stride in the 80s, quickly becoming a favorite of professional anglers looking for high-sensitivity rods. Slightly lighter weight than fiberglass and with faster action and higher power, graphite fishing rods are preferred by more experienced anglers in search of a versatile rod. Because graphite is rigid and unyielding, graphite fishing rods are available in longer lengths than fiberglass, allowing for improved reach and accuracy from a distance.

Composite fishing rods are rods made from a combination of fiberglass and graphite parts, often with other materials included to improve integrity. Like the combination suggests, composite fishing rods include the best features of both fiberglass and graphite, making them popular among anglers looking to step up their game without over-spending on a graphite rod.

Depending on where the fiberglass and graphite components of a composite rod meet, the rod will have varying degrees of flexibility and power. Some composite rods are built to flex close to the butt like a fiberglass rod, whereas others feature higher rigidity like graphite. Featuring the flexibility of fiberglass with the sensitivity of graphite, composite rods are more versatile than single-material rods, and less expensive, too.

If you want the best of both worlds and are looking for a rod that offers flexibility and strength, composite is the way to go. When looking at composite rods, you should understand that you can find a balance between sensitivity and action that works for you. Experienced anglers will likely want sensitive rods with a fast action, and less experienced anglers may want to look for rods that have a slow to medium action for casting forgiveness.

Fishing with a bamboo rod can be a whole lot of fun, but you might want to bring along a fiberglass or graphite rod if you plan to be out on the water all day long. A well-crafted bamboo rod can be quite heavy, and though you might not feel it during the first few hours of fishing, your arms will certainly be tired if you try to fish on a bamboo rod all day long.

When selecting a fly rod, it is important to keep your personal level of experience in mind. If you are a beginner, a mid-action, mid-weight rod is your best option, since these afford the most control. Fast-action, high powered rods can be difficult to learn on and are best reserved for experienced anglers.

Graphite rounds can be used to enlarge a hole blown in a tube, as a flaring tool, or to poke an indentation in the glass sidewall. In heat treating, graphite rods are used to support hearth rails or beams, allow for thermal expansion of graphite plates, as support posts in fixtures, and for many other things. In the lab they are also a useful material used as electrodes, stir sticks, and for other reaction purposes.

Fiberglas rods usually fall in the slow- to medium-action class. They are great for soft presentations of large baits, an excellent choice for working rough bottom where hang-ups are the norm, ideal for tangling with soft-mouthed species such as weakfish from which stiffer rods might tear the hook, and they are durable enough to take the pounding that novice anglers typically dish out.

Think of the difference between fiberglass rods and graphite rods as being similar to the difference between a swamp maple and an oak tree blowing in the wind. The oak is stronger and quicker to resume its stiff position than the swamp maple, but the maple can sway in the breeze without snapping. Picking a rod, to a large degree, is finding the right amount of sway to meet your needs.

Composite rods incorporate both fiberglass and graphite or other fibers in their design. As you might expect, then, they perform somewhere between the two extremes. They generally cost more than fiberglass rods but less than graphite, are more sensitive than fiberglass but less sensitive than graphite, and, although not quite as powerful as graphite on the lift, they are less likely to snap under heavy or sudden loads.

Combining the benefits of fiberglass and composites results in a rod with increased sensitivity, more durability and great strength. This makes for a nice blend of characteristics and thus, composite rods are often the best choice if versatility is what you are looking for in an inshore rod.

The graphite bricks act as a moderator. They reduce the speed of neutrons and allow a nuclear reaction to be sustained. They also perform an important safety function by providing the structure through which CO2 gas flows to remove heat from the nuclear fuel and the control rods used to shut down the reactor are inserted.

We have always known the graphite that makes up the cores of these reactors would change over time. We cannot replace or repair the graphite so we have been working over many years to understand and prepare for these changes.

Cracking happens when the stresses in the graphite bricks changes over time. On their own, cracks do not make a reactor unsafe but we need to be able to show that they will not change the shape of the channels where the fuel sits in a way that will stop the reactor from shutting down in an earthquake larger than the UK has ever experienced. We also need to be sure that any fragments that come loose after cracks form do not affect the temperature of the fuel or stop us removing it from the reactor.

Through continual monitoring and regular inspections we have been able to show conclusively the safe shutdown of our reactors during normal operation and in a highly unlikely earthquake. Work is also underway to prove that if any fragments of graphite come loose during the ageing process that they would not be a challenge to continued operation.

To monitor the condition of the reactors, we carry out frequent graphite inspections at all our stations, either during statutory outages which take place every three years or during more regular special graphite inspection outages.

We remove the fuel and lower down specialist measuring equipment and cameras to film the inside of the channels. This allows us to see any cracks that have formed and, if they have been observed before, see if they have changed. Each time we monitor we inspect enough channels to give us a good understanding of the state of the core. We also remove samples of graphite, which we send for detailed analysis to confirm the level of weight loss.

In 2014, the first crack related to the aging of the graphite was identified in Reactor 4 at Hunterston B. Over the next eight years regular inspections allowed close monitoring of the progression of graphite cracking at the site.

During graphite inspections in March 2018 we identified a slightly higher rate of cracking than expected and kept the reactor offline for more than two years to allow us the time to carry out additional inspections, modelling and analysis and present a safety case, based on new evidence, to the regulator for assessment.

In October 2018 we also decided to carry out graphite inspections on Reactor 4. The results showed that the graphite was ageing as expected but we kept the unit offline while we refreshed the safety case. In August 2019, the ONR gave approval for the unit to return to service for a period of around 4 months, allowing it to reach almost the same power output as Reactor 3. Approval for a further run of 6 months was granted before another round of graphite inspections.

Fuel elements - AGR fuel consists of stainless steel pins. These pins are made up of small pellets containing uranium, which are built into a graphite sleeve. Seven or eight smaller fuel elements are fixed together vertically to form one large fuel element.

We stock a variety of round graphite sizes. Due to its incredible resistance to high heat, graphite uses include rocket motor nozzles, linear bearings, Stirling motor pistons, welding stands, glass blowing and jewelry making.

The Medium grain is similar to what popular commercial HPR motor vendors use as reusable nozzle material. The Fine is appropriate for more technical projects or the more particular experimenter. This new stock is available in 2", 3", and 4" diameters and 12" lengths only for medium grain and 24" lengths only for fine grain. In addition, we have 4" fine graphite rods in various lengths.

Using graphite material is a relatively new development in the construction of fly rods. The first graphite fly rods came to the market in the 1960's, and their popularity exploded with the invention of graphite ferrules in the 1980's. Ferrules are the slide-in joints that connect two pieces of fly rod. Graphite ferrules nearly eliminate any "dead spots" in the bend and feel of the rod. 041b061a72
