Win more bids with our Corrosion (MIC) Prevention Solution backed by a 15-Year Leak Warranty.

Small changes, Big profits: Do you want to win more bids at lower prices and achieve higher profits — while securing maintenance and inspection work along the way? Our Corrosion (MIC) Prevention Solution: clean-interior steel fire sprinkler pipes + Nitrogen inerting (WPNI, supplied by Tyco, ECS, Potter, or equivalent) with 15-Year Leak Warranty in wet sprinkler system make it possible.

  The following is a comparison table of the 15-year total costs of Corrosion Prevention Solution and Traditional Black Pipe in wet sprinkler system.

What this means for your business

• 15-Year Warranty → Predictable Costs → Smarter Bid:
    With a 15-year manufacturer-backed leak warranty, your 15-year system costs become predictable, so you can set confident, competitive bid prices while protecting your margins.
• Win More Bids with 30% Lower Total Cost over 15 Years
    Our Corrosion (MIC) Prevention Solution is designed to deliver a 15-year total cost that is typically at least 30% lower than standard black steel pipe—making it easier for you to win more bids.
• Pipe Is a Small Cost—The Savings Are Not
    On any fire sprinkler project, pipe is only a small portion of the total installed cost. By reducing corrosion, leaks, and premature replacements, our solution turns that small material choice into major savings over the life of the system and a lower 15-year total cost.
• Capture Leak-Repair Profits Up Front in the Original Bid:
     As an Authorized Contractor, you can price new installations to reflect the 15-year leak-free value you’re delivering to the owner. In practice, this lets you move profit that would normally come from unplanned leak repairs into the original project bid.
• Secure Recurring Revenue with Warranty-Linked Services:
     At the same time, you maintain steady recurring revenue from NFPA 25 inspections and the ongoing oxygen / nitrogen control and re-inerting work required under our program, since the owner’s 15-year leak warranty depends on that service being performed and documented by you.
• Reduce Emergencies and Focus on High-Margin Installations:
     By greatly reducing internal-corrosion leaks, you spend less time on emergency callouts and can keep your fitters focused on scheduled, higher-margin installation work.

How it works on your projects

Step 1 – Start with clean-interior pipe
   Use our UL/cUL listed clean-interior steel fire sprinkler pipe in the wet system. It installs like standard steel but is manufactured to minimize interior residues that can accelerate internal corrosion.
  Want the technical details? See “How to Prevent MIC”

Step 2 – Commission at low oxygen (O₂ ≤ 2%)
  At handover, work with your nitrogen system vendor (Tyco, ECS, Potter, or equivalent) to perform Wet Pipe Nitrogen Inerting (WPNI) and NFPA 13 air venting. The goal is an oxygen level of ≤ 2% at representative high points, documented in your handover package.
  The science behind low oxygen is explained in “How to Prevent MIC”.

Step 3 – Document and maintain
  You perform NFPA 25 inspections, testing, and maintenance, plus annual oxygen spot checks and re-inerting after major water additions or significant modifications. Keeping records (NFPA 25 reports, O₂ logs, re-inerting records) maintains the system within the design envelope.

Step 4 – Issue the owner’s 15-year leak warranty
  Once the system is installed, inerted, and documented according to the program, we issue a project-specific 15-year limited leak warranty certificate directly to the building owner for qualifying through-wall leaks in our pipe. You remain their NFPA 25 and nitrogen service provider.

For AHJ-reviewed projects
  We provide a complete acceptance package—including UL & cUL listing, O₂ ≤ 2% inerting logs (WPNI, supplied by Tyco, ECS, Potter, or equivalent), NFPA 13 air-venting and a Clean-Pipe Evidence Pack—so reviewers can make an informed approval based on documented outcomes.

Why Do Your Customers Love Our Products?

  Significantly Reduced Total Cost of Ownership (TCO):Our pipes are priced slightly higher than traditional fire sprinkler pipes, but our Corrosion Prevention Solution extends their lifespan, significantly reducing the Total Cost of Ownership (TCO) for your customers. In an era of soaring steel prices, it’s more important than ever to spend wisely.

  Dependable in Emergencies: Our solution maintains full functionality during fires, providing safety when it matters most. According to NFPA's national research, the leading cause of sprinklers failing to operate is that the system was shut off before the fire, often due to leaks, thereby making them ineffective when needed most. An NFPA analysis of U.S. fires from 2010–2014 found that three out of every five (59%) non-operations were due to shut valves often due to leaks.

  Attractive for LEED Green Building Projects: Our solution supports sustainability by reducing replacement frequency, minimizing material waste, and meeting environmental standards.

The Advantage of Our 15-Year Limited Leak Warranty:

1. Owner-facing, manufacturer-backed: For each qualified project, we issue a project-specific 15-year limited leak warranty certificate directly to the building owner, so the owner knows the pipe manufacturer stands behind the system.
2. You keep the maintenance revenue: The warranty is conditional on NFPA 25 inspections, oxygen measurements and re-inerting after major water additions — work that must be performed and documented by you. The owner’s warranty depends on your ongoing service.
3. Easier to win bids: With virtually no unplanned leak repairs expected from internal corrosion in our pipe, you can offer predictable lifecycle costs and a stronger value story than traditional black pipe.
4. Maximize customer lifetime value: An owner-facing warranty that depends on your NFPA 25 and WPNI service helps you secure long-term maintenance and inspection contracts instead of one-off repair work.

  Want the 15-Year Limited Leak Warranty details? See “Leak Warranty”

  The warranty is offered solely by us; WPNI or equivalent providers are not co-warrantors.

  Corrosion caused by MIC leads to pipe leakage within 12 to 15 years. This means that if there is no pipe leakage within 15 years of use, leaks due to MIC will not occur. Therefore, if no leakage happens during our warranty period, it indicates that, with routine nitrogen inerting performed, the pipes will not leak in the future and the pipes can last for 50 to 70 years, similar to the lifespan of steel pipes several decades ago, before the impact of MIC.

  Our company is a Clean-Interior Steel Fire Sprinkler Pipe manufacturer that sells directly to customers.

  We also provide extra steel pipe to be stored by the contractor or owner so that repairs can start immediately without waiting for international shipments.

  If the time from project acquisition to installation is short, it's not difficult, as long as you own or rent a warehouse to stock our steel pipes, you can start a business with unlimited potential for future development.

Debris-Free Easy Installation, Lower Costs: 

1. With a Fabrication Shop: With our "Debris-Free Easy Installation," which simplifies the processing procedure, you can significantly reduce the factory work required for each project. This allows your factory to greatly expand its capacity to take on more projects, thereby significantly increasing your revenue.

2. Without a Fabrication Shop: "Debris-Free Easy Installation" requires only minimal processing, such as cutting and grooving the steel pipes at the job site, and enhances installation efficiency.

  What is Debris-Free Easy Installation: Our innovative pipes simplify the installation process. Simply cut the pipes to the lengths specified in the blueprint and connect them using Threaded Outlet Couplings with Gaskets to assemble the entire wet sprinkler system directly. Designing the blueprint with uniform pipe lengths (e.g., our standard lengths) can further streamline on-site installation, saving time and labor. Additionally, we offer grooving services for both ends of the pipes to meet your specific project requirements.

  Our Corrosion (MIC) Prevention Solution —clean-interior UL & cUL steel fire sprinkler pipe + nitrogen inerting (WPNI, supplied by Tyco, ECS, Potter, or equivalent) + NFPA 13 air venting + documentation—delivers the following Competitive Advantages:

- Spec-ready acceptance: Submittals include a Clean-Pipe Evidence Pack, an O₂ ≤ 2% acceptance log at representative high points, and NFPA 13 air-venting confirmation—helping AHJs approve faster.

- Fewer callbacks: Clean interiors and a documented low-oxygen handover reduce early deposits/biofilm and the risk of under-deposit/MIC-related issues.

- 15-Year Limited Leak Warranty issued directly to owners: When installed and maintained per program, our pipe in the wet sprinkler system is covered for qualifying leaks caused by internal corrosion (including MIC). We issue a project-specific warranty certificate directly to the building owner, while the fire protection contractor keeps the NFPA 25 and WPNI service revenue.

- Lower lifecycle cost: An outcome-based approach (no chemicals left in service water) helps lower TCO by reducing leak repairs and unplanned shutdowns. A simple TCO worksheet is available upon request.

- Fire exposure ready: Noncombustible steel is suitable for fire exposure and looks clean in exposed installations thanks to its exterior galvanized finish.

- Simple upkeep: No ongoing chemical program—just annual O₂ spot checks and re-inert after major water additions to keep oxygen low.

- Sustainability minded. Steel is recyclable and durable; longer service intervals mean less replacement waste and may support owner sustainability goals.

- No internal zinc coatings: We do not rely on internal galvanizing or in-service chemical additives; control is achieved through cleanliness + oxygen management + documentation.

Steel for fire exposure—without the corrosion anxiety.

  Why steel—and how we control corrosion

Fire events demand noncombustible steel. The industry’s concern has been internal corrosion (including MIC) in wet systems. Our outcome-based program addresses that concern without chemicals left in service water: a clean interior, NFPA 13 air venting, and WPNI to achieve a low-oxygen handover (O₂ ≤ 2%) at representative high points. The acceptance is documented (O₂ log, Clean-Pipe Evidence Pack, venting confirmation), and we back the job with a 15-Year Limited Leak Warranty for internal-corrosion leaks in our pipe.

What this means for contractors

- Fire exposure ready: noncombustible steel for demanding environments and clean, professional-looking exposed installations.

- Fewer callbacks: low-oxygen, clean handovers reduce early deposits/biofilm and MIC risk, so you spend less time chasing leaks.

- Spec-ready: O₂ ≤ 2% acceptance log, NFPA 13 venting confirmation, and a Clean-Pipe Evidence Pack make it easier to get AHJ approval.

- Owner-facing, contractor-powered warranty: We issue a 15-year limited leak warranty certificate directly to the building owner, but the warranty depends on NFPA 25 inspections, oxygen checks, and re-inerting performed and documented by you or another qualified contractor. We do not sell or service nitrogen systems or NFPA 25 inspections — you keep that revenue.

  Josh is a clinical attending physician who, by chance, came into contact with the fire protection industry. He discovered that Microbiologically Influenced Corrosion (MIC) severely damages steel fire sprinkler pipes. Leveraging his expertise in microbiology, Josh developed an innovative solution to address MIC. His breakthrough aims to solve the global issue of MIC-induced damage to steel fire sprinkler pipes in wet sprinkler system.

  Manufacturing Clean-Interior Steel Fire Sprinkler Pipes is a complex and meticulous process. If even one small step is incorrect, the pipes will lose their ability to prevent MIC. We have invested a great deal of time and money in continuous research and development, finally developed solution that truly prevent MIC, solving one of the most challenging problems in the global fire protection industry. Therefore, we have great confidence in our product and can guarantee its MIC prevention capabilities without any doubt, offering a 15-year Leak Warranty, which is unmatched in the industry.

  Here is a picture of Microbiologically Influenced Corrosion (MIC).

  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 Corrosion (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.
