Chlorine Fiberglass Tank Repair
Chlorine fiberglass tanks are common in industrial facilities, like chemical plants or pulp and paper mills, and are used for storing and transporting hazardous chemicals. When these tanks require repair, it is important to consider all the factors that could affect their integrity before proceeding with repairs. In this article, we will provide an overview of the inspection process for chlorine fiberglass tanks and the steps involved in repairing them safely and effectively.
We repair and reline tanks, pipes, and containment areas for chlorine processing:
Insights into Manufacturing Chlorine
Chlorine is an essential element used in a variety of industries and is primarily produced through the electrolysis of sodium chloride or potassium chloride. During this process, chlorine gas is released along with hydrogen gas and sodium hydroxide or potassium hydroxide as by-products, respectively. To manage the vast quantities of hydrogen gas created during electrolysis, companies have developed various methods to safely release it into the atmosphere or transport it for other uses, such as fuel.
There are two main ways that chlorine is manufactured from the electrolysis process. The first way involves passing an electric current through a concentrated solution of either sodium chloride or potassium chloride dissolved in water, which splits up the compound into its component ions and results in the formation of chlorine gas at the negative electrode (anode). The second method is called chloralkali electrolysis and involves using brine (salt water) instead of just salt. This process yields both chlorine and caustic soda (sodium hydroxide), which can be separated easily by bubbling off the chlorine gas generated at the anode.
The amount of energy required to produce chlorine through electrolysis has decreased significantly over time due to advancements in technology and new processes being developed. For example, advances in membrane technology have enabled large industrial-scale production plants to produce more efficient results while consuming less energy than before. Additionally, research suggests that renewable sources such as solar power could further reduce costs in large-scale production plants (1).
Overall, the electrolysis process has enabled manufacturers to safely obtain clean and inexpensive sources of chlorine for use across many industries, including disinfectants manufacturing, water treatment facilities, and paper mills, among others (2). With continued technological innovations aimed at lowering their environmental footprint, these manufacturing processes will continue to provide affordable solutions for economies around the world.
FRP and Chlorine
When chlorine gas exits the cell, it needs to be quickly cooled and dried as it can reach temperatures of up to 80 degrees Celsius. The excess moisture in this gas causes iron pipes to corrode, leading many organizations to instead turn to FRP (Fibre-Reinforced Plastic) piping systems which are highly non-corrosive and resistant to abrasion. These systems, along with tanks, ductwork, fan casing, and custom products, make for a perfect substitute for those wishing to delay corrosion.
Chlorine gas is typically compressed through two processes: liquid ring and centrifugal. These methods involve releasing non-condensable gases and extra chlorine gas into the liquefaction system in order to regulate pressure levels. Afterward, these gases are transferred into a scrubber where they would normally corrode the containers as well as impair plant efficiency if not appropriately managed. This is why FRP solutions are highly sought after when it comes to chlorine storage - they are engineered with corrosion resistance in mind and have higher durability compared to other materials, such as steel which tend to wear out over time.
FRP equipment has been found to be exceptionally lightweight without compromising on strength, making them an ideal choice for many industries, including chemical processing and wastewater treatment plants that handle hazardous chemicals like chlorine. Also, some FRP components are designed with specialized coatings that further increase the product’s resistance against harsh chemicals such as those found in chlorine gas. Moreover, installation of FRP piping systems is much faster than traditional steel pipes due to their simple design structure - there are no complex welding processes or additional fittings needed during assembly. All of this makes FRP an ideal choice for those looking for a long-lasting solution when it comes to storing chlorine gas or any type of corrosive substance.
Inspection and Testing Process for Chlorine Fiberglass Tanks
When evaluating a chlorine fiberglass tank for repair, it is important to perform a thorough visual inspection of the tank and any associated pipes or valves. During this inspection, look out for signs of damage, such as cracks, holes, corrosion, or other deformities. If there is any visible damage found during the initial inspection, further testing should be conducted to determine the extent of the damage. This can include hydrostatic testing or ultrasonic thickness testing, which can help identify areas where additional reinforcement may be needed.
Benefits of Repairing vs. Replacing Chlorine Fiberglass Tanks
Repairing a damaged chlorine fiberglass tank can often be more cost-effective than replacing it outright. Additionally, repairing an existing tank provides a much quicker turnaround time compared to fabricating a new one from scratch. This makes repairs ideal when time is of the essence or when budgets are tight.
Another benefit of repairing versus replacing is a reduction in logistical risk. We performed two tank inspections for one of our service partners, and they decided to repair one tank and replace the other. The tank that was relined and repaired was only down for a few days, requiring minimal safety risk. The tank that was replaced required a roof removal, crane, weeks of downtime, and delivery, and was unfortunately cracked during the installation. As a certified tank repair center for tanks, we were called back to the location to repair the new tank, costing the water treatment facility additional costs and downtime.
Steps Involved in Chlorine Fiberglass Tank Repairs
When it comes to performing repairs on chlorine fiberglass tanks, there are several steps involved to ensure that they are done correctly and safely.
The first step is surface preparation—this involves removing any loose material from around the area being repaired, as well as cleaning off any dirt or debris that may have accumulated over time.
Next come the actual repair materials—fiberglass resin is typically used for this application, along with reinforcing mats or cloths if necessary, depending on how extensive the damage is. Once these materials have been applied according to the manufacturer’s instructions (or as specified by an engineer), they must then be allowed to cure completely before moving forward with the re-assembly of components such as pipes and valves associated with the tank itself.
Finally, once all of these steps have been completed correctly, additional testing should be done in order to properly evaluate the strength of repairs made on the tank itself before allowing it back into service again. The tank may need to undergo a pressure test before re-filling tank with the previously stored material.
Safety Considerations When Repairing Chlorine Fiberglass Tanks
When performing repairs on any type of industrial equipment—especially those containing hazardous chemicals like chlorine—safety precautions must be taken at all times to protect workers from potential harm caused by exposure to such materials or mishandling during repairs themselves (which could cause further damage).
In addition to proper protective gear such as masks and gloves when handling hazardous materials directly, proper ventilation should also be provided at all times while working inside enclosed spaces like storage tanks to prevent the buildup of dangerous fumes, which could result in potential health risks if inhaled by workers nearby.
Lastly—but certainly not least—only professionals who possess knowledge and experience regarding safe industrial maintenance practices must handle any type of repair work on chlorine fiberglass tanks (or other similarly hazardous equipment).
