The World's Only Effective Corrosion (MIC)-Preventing Steel Fire Sprinkler Pipes in Wet Sprinkler Systems

  Why choose our Corrosion (MIC)-Preventing Steel Fire Sprinkler Pipes in Wet Sprinkler Systems?

  Because our fire sprinkler pipe is the only one in the world that truly prevents corrosion and withstands high temperatures.

  While many fire sprinkler pipes on the market claim to be corrosion-resistant, they either have poor corrosion resistance or cannot withstand high temperatures. For example, applying anti-MIC coatings inside the steel fire sprinkler pipe often leads to a significant decrease in corrosion resistance due to factors such as a variety of anaerobic bacteria, uneven application, and degradation over time, rendering them ineffective against MIC. Similarly, fire sprinkler pipes made from corrosion-resistant materials such as CPVC or stainless steel are not capable of withstanding high temperatures, leaving the fire protection system vulnerable to destruction in the event of a fire.

  Furthermore, injecting nitrogen into wet sprinkler systems leaves behind 2% oxygen, allowing aerobic bacteria to persist, leading to MIC and consequently destroying wet sprinkler systems.

  We have finally produced the only fire sprinkler pipe, both theoretically and practically, that can alleviate the troubles of corrosion, including Microbiologically Influenced Corrosion (MIC) and Oxygen Corrosion, and withstand high temperatures during a fire. This revolutionary product can safeguard wet sprinkler systems from corrosion-induced blockages and water leaks, thereby significantly extending their operational lifespan. Building owners no longer need to worry about issues with wet sprinkler systems.

  If you are a fire protection company aiming to maximize profits by installing the new wet sprinkler systems, joining our regional exclusive franchise system and using our corrosion-preventing fire sprinkler pipes is the best choice.

  Our Corrosion-Preventing steel fire sprinkler pipes (external galvanized/internal black steel fire sprinkler pipes with no debris inside) have the following competitive advantages:

1. The Only Solution for Almost 100% MIC Prevention in wet sprinkler systems: By utilizing our capability to coat the inner surface of steel pipes with oil, remove and prevent debris, inside the pipes, and rapidly exhausting the oxygen in the trapped air, we can almost 100% prevent the growth of aerobic bacteria, thus almost 100% preventing MIC. Please refer to the following description for How do our pipes prevent MIC. The Anti-MIC coatings available on the market, when applied to the interior wall, are essentially ineffective in preventing the occurrence of MIC.
2. The only fire sprinkler pipe that can prevent corrosion and withstand high temperatures: No need to compromise for CPVC pipes or stainless steel pipes because although they are corrosion-resistant, they cannot withstand high temperatures.
3. Ensure the proper operation of fire systems: The byproducts generated by MIC can clog steel pipes and sprinklers, potentially causing the fire system to malfunction in the event of a fire, resulting in loss of life and property. By using our steel pipes, MIC formation is prevented, allowing the fire system to function correctly in case of a fire.
4. Prevent property damage due to leaks: MIC corrodes steel pipes, leading to leaks that can damage the contents beneath the pipes and result in property loss.
5. Extend the lifespan of your fire system by at least three times: Schedule 10 steel pipes corroded by MIC become unusable after 12-15 years of use. With our Corrosion-Preventing steel fire sprinkler pipes, which do not generate MIC or Oxygen Corrosion, they can last for 50-70 years or more. In the early days when MIC was not an issue, the typical lifespan of fire steel pipes was approximately 50-70 years.
6. Saving a significant amount of money in the long term: Utilizing our pipes for an extended duration results in the lowest overall cost. When considering the long-term expenses associated with maintaining a fire sprinkler system, our Corrosion-resistant fire sprinkler pipes can lead to savings equivalent to the cost of at least two complete replacements due to MIC corrosion. This includes the expenses related to steel pipes, sprinkler head processing, dismantling, and installation.
7. Aesthetic steel pipes: Because the steel pipes are coated with zinc on the outside, they are highly attractive and suitable for use in exposed fire sprinkler systems.
8. By using thinner piping, we can lower costs without compromising on quality or safety. Thinner piping is less expensive to manufacture and transport, and requires less labor to install.
9. Minimal maintenance costs: Because our steel pipes do not corrode, they require minimal upkeep and repairs, saving you time and money in the long term.
10. Eco-friendly: Using our steel pipes can earn you credits in LEED and BREEAM because our steel pipes possess the following features: using materials with longer life spans, utilizing our schedule 7 thin steel pipes can reduce steel consumption, and since our steel pipes are made of steel, they enable the reuse of building materials.
    
11. Remove and prevent any debris on the interior of the pipe: Debris is a necessary factor causing MIC, and without debris, there is no MIC. Please refer to the following description for How do our pipes prevent MIC.
12. No internal galvanized coating: Having zinc on the inside of the steel pipe can lead to corrosion of the interior wall after water is introduced, so we ensure that there is no zinc present inside the steel pipe.

***How do our pipes prevent MIC?

  After the installation of the fire sprinkler system, water containing aerobic and anaerobic bacteria is introduced into the wet sprinkler system. Following the water filling, some trapped air may remain inside the steel pipes. The oxygen within this trapped air reacts with the iron on the inner walls of the pipes, resulting in the formation of iron rust (debris). Aerobic bacteria can attach to these rough iron rust (debris) surfaces or pre-existing rough debris surface along the waterline. They utilize the nutrition in the debris and the oxygen inside the trapped air to survive and establish biofilms.

  The biofilm formed by these aerobic bacteria creates an environment conducive to the survival of anaerobic bacteria, allowing anaerobic bacteria that are not typically suited for oxygenated water to thrive and reproduce within these biofilms. Most of these anaerobic bacteria are iron-loving bacteria, like Sulfate-Reducing Bacteria (SRB), leading to corrosion (MIC) of the inner walls of the steel pipes and ultimately damaging the steel fire sprinkler pipes.

  The purpose of our steel pipes is to prevent the growth of aerobic bacteria because preventing the growth of aerobic bacteria can also prevent MIC. Organic matter, rough surfaces, and oxygen are essential conditions for the growth of aerobic bacteria, and none of them can be lacking. The oxygen inside the trapped air within the steel pipes cannot be completely eliminated by anyone, so we need to prevent the combination of organic matter and rough surfaces. Only debris satisfies the conditions for organic matter and rough surfaces. Therefore, removing and preventing debris can prevent the growth of aerobic bacterial. We achieve nearly 100% prevention of aerobic bacteria formation by employing methods such as 1. coating the inner surface of the steel pipes with oil, 2. clearing and preventing debris within the pipes, and 3. the limited quantity of oxygen in the trapped air is rapidly exhausted.

  1. Coating the inner surface of the steel pipes with oil : The oil on the inner surface of the steel pipes prevents the growth of aerobic bacteria. 

  2. Clearing and preventing debris within the pipes : Our steel pipes have been thoroughly cleaned of debris and organic matter during the manufacturing process, ensuring that there is no presence of debris or organic matter inside the pipes. When water is introduced into the steel pipes, in cases where there are gaps in the oil on the inner surface, a reaction occurs between the iron on the inner walls of the pipes and the oxygen inside the trapped air, resulting in the formation of iron oxide (debris) (4Fe + 3O₂ → 2Fe₂O₃). At this point, the zinc on the exterior of the pipes serves as cathodic protection, releasing electrons that combine with the water inside the pipes to produce hydrogen gas (2H₂O + 2e⁻ → H₂(gas) + 2OH⁻). The hydrogen gas inside the steel pipes immediately reacts with the iron oxide (debris) on the inner walls, reducing the iron oxide back to iron and water (Fe₂O₃ + 3H₂ → 2Fe + 3H₂O). In this way, it prevents the iron on the inner walls from rusting(debris) in the presence of oxygen. Without the presence of debris within the steel pipes, aerobic bacteria are deprived of the opportunity to attach and grow on debris.

  3. The limited quantity of oxygen in the trapped air is rapidly exhausted : Moreover, during the process of iron and oxygen combining to form iron oxide (debris) (4Fe + 3O₂ → 2Fe₂O₃), the limited quantity of oxygen in the trapped air is rapidly exhausted(Only 0.005 grams of zinc outside the steel pipe is needed to consume the oxygen inside each trapped air within the steel pipe on average). Subsequently, no oxygen remains within the confined space. This absence of oxygen hinders the survival of aerobic bacteria.

In practice,

  We sold our Corrosion-preventing fire sprinkler pipes to Las Vegas 17 years ago. Two years ago, a casino needed to redecorate and uninstall these pipes. The pipes were checked and found to have no corrosion or biofilm (MIC) inside them after being installed for 15 years.

  There are fire sprinkler pipes made of CPVC material available on the market. While they offer corrosion resistance, their heat resistance typically ranges from 150°C (302°F) to 200°C (392°F). In the event of a fire with temperatures exceeding 200°C (392°F), the entire fire sprinkler system would be rendered inoperable. Generally, fire temperatures surpass 1000°C. Using our Corrosion-Preventing Steel Fire Sprinkler Pipes not only prevents corrosion but also withstands high temperatures, eliminating the need to compromise with CPVC pipes.

  In the market, there are fire sprinkler steel pipes with anti-MIC coatings applied on the interior wall like Bullmoose and Wheatland. However, the effectiveness of anti-MIC coatings can be compromised for several reasons:

1. Variety of Anaerobic Bacteria: There are numerous types of anaerobic bacteria, and anti-MIC coatings may not be able to completely eliminate all of them, allowing surviving anaerobic bacteria to cause MIC by corroding the steel pipes.

2. Uneven Application: The application of this coating is not always uniform in terms of concentration and thickness. This non-uniformity can make the coating vulnerable to MIC penetration.

3. Degradation Over Time: Over time, the coating may degrade or wear off, reducing its efficacy. As the coating deteriorates, bacteria find it easier to grow and potentially cause MIC.

  So, the ineffectiveness of anti-MIC coatings can be attributed to the variety of anaerobic bacteria, uneven application, and the natural degradation of the coating over time, allowing MIC-promoting conditions to develop.

 If an existing wet sprinkler system experiences MIC, it indicates that a significant portion of the wet sprinkler pipes within the system is already affected by MIC. This can lead to blockages and water leaks in the fire sprinkler pipes over time. We recommend replacing all the fire sprinkler pipes with our MIC-Preventing steel fire sprinkler pipes to prevent corrosion from recurring. Switching to our product can relieve you from the concerns of corrosion in your wet sprinkler system. Some might suggest using biocides to kill the anaerobic bacteria causing MIC, but biocides cannot entirely eliminate these bacteria from the wet sprinkler system, leading to their resurgence and further corrosion of fire sprinkler pipes.
