FAQs of Fire Protection Manifold

1. What is the function of a fire protection manifold?

Its core function is to distribute firefighting water sources centrally. It provides liquid to multi-branch sprinklers, fire hydrants, or fire-extinguishing equipment simultaneously. It makes sure pressure is stable, and flow is balanced at each terminal during firefighting.

2. How to select a fire protection manifold for fire protection systems?

Pipe diameter is calculated based on total system flow rate, number of branches, single branch designed flow rate, and matched with system working pressure (commonly 1.6MPa/2.5MPa), providing system parameters for manufacturer customized selection to ensure compatibility.

3. What customizations are available for fire protection manifolds?

Plumberstar manufacturer can provide complete customization services. The number of branches can be designed as needed (commonly 2-12 branches). Interfaces can be threaded (NPT/BSP), flanged, or of other types. Installation methods include wall-mounted, vertical, and others, to adapt to different on-site layouts.

4. What’s the difference between fire protection and regular industrial manifolds?

The core difference is that fire protection manifolds must meet emergency reliability in fire scenarios, with a higher pressure rating, faster fluid response speed, and all components must pass fire-specific certifications. Regular manufacturers will strictly implement this standard to avoid flammable or failure-prone risks.

5. How to choose a manufacturer’s reliable qualifications for the fire protection manifold?

1. Fire Protection Special Qualifications
Fire protection products must have official certifications. Like CCCF mandatory certification in China, UL/FM certifications in European and American markets, and CE + EN14420 certifications in the EU.
You need to check the certificate validity period and certification scope. Ensure they cover the fire protection collector’s specifications, including pressure ratings (such as PN16/PN25) and the types of medium used (e.g., water/foam mixture).
Plumberstar products have passed the corresponding fire protection special certifications for each market. We provide the certificates together with the goods. You can verify them through official channels.
2. Production & System Qualifications
Factories need ISO 9001 quality management system certification and ISO 14001 environmental management system certification.
If it’s a pressure collector, it also requires a special equipment manufacturing license (TS certification). This ensures compliance with processes like welding and non-destructive testing.
Plumberstar’s factory has all the above system certifications. Our welders all hold special equipment welding qualification certificates.
3. Material & Safety Compliance
You need to provide material certifications. Such as material reports and spectrum analysis reports for 304/316L stainless steel and carbon steel.
Seals must meet fire medium resistance standards. Products matched with drinking water systems must pass NSF/ANSI 61 certification.
Plumberstar provides complete material traceability documents and inspection reports.

6. What key specs must be followed when installing fire protection manifolds?

It is necessary to ensure the installation surface is flat and firm, the interface is tightly sealed, and avoid pipeline stress transmitting to the valve body; branch connection must be constructed according to the designed flow direction, and a pressure test should be conducted after installation (qualified standards refer to the manufacturer’s requirements). Illegal modification is strictly prohibited.

7. What is the packaging of fire protection manifolds?

Plumberstar manufacturer uses customized packaging. The outer layer is a strong corrugated carton or plywood box. The inside is fixed firmly with EPE pearl cotton and foam. Key interfaces have protective caps. It also has moisture-proof film to prevent rust.

8. Does the manufacturer provide customs clearance documents for the fire protection manifold?

Yes. The destination country or region has requirements. Plumberstar manufacturer will provide a full set of customs clearance documents. These documents include a commercial invoice, a packing list, a certificate of origin, a product test report, a fire certification certificate, and so on.

9. How is quality consistency maintained across fire protection manifold batches?

Centralized Procurement & Fixed Suppliers
Plumberstar signs long-term strategic cooperation agreements with top steel and copper plants. We lock in brands and material standards for core raw materials like 304/316L stainless steel, carbon steel, and lead-free brass (e.g., complying with EN 10216 and ASTM A312).
We also maintain a 60-day safety stock. This avoids material quality differences caused by raw material batch fluctuations.
Batch Coding & Full Traceability
Every batch of raw materials gets a unique batch code when entering the factory. The code is entered into our traceability system right away. It records supplier info, material certificate numbers, spectrum analysis reports, and warehousing time.
During production, the raw material batch code is linked to the product’s traceability code. This ensures the raw material source of each fire protection manifold is fully verifiable and traceable.
Full IQC Inspection & Batch Sampling
100% of each raw material batch undergoes spectrum analysis, hardness testing, and corrosion resistance testing.
We also take 5% samples for tensile strength and impact toughness tests. Unqualified raw materials are rejected outright. No low-quality materials make it into the production process.
