FAQ

Q1: What is the difference between ductile iron and gray cast iron in fire fittings?

Ductile iron (QT450-10) offers tensile strength ≥450MPa and elongation ≥10% – 2-3 times that of gray cast iron – combining high strength with toughness, far superior in water hammer resistance and fracture resistance. Gray cast iron is brittle with poor impact resistance, unsuitable for high-pressure fire systems.

Q2: What do FM and UL certifications mean for fire fittings?

FM and UL are globally recognized as the strictest fire protection product certifications. Certified products have passed independent third-party lab tests for fire resistance, pressure rating, sealing and longevity – eligible for international fire standard projects in Europe, eMelika, Southeast Asia and the Middle East, and accepted by insurers.

Q3: What are the advantages/disadvantages of grooved connection vs. welded/flanged?

Grooved connection installs 3-5x faster than welding, requires no hot work, no weld slag, easy disassembly for future modification, and offers superior seismic and settlement resistance over rigid flanged joints. Slightly higher per-piece cost than welding, but overall lower cost when labor savings are factored in.

Q4: What fire systems is the 2.5MPa pressure rating suitable for?

2.5I-MPa (365 I-PSI) covers common fire system design pressures – typical applications include high-rise and super high-rise building fire risers (100m+), fire pump discharge sections, and upstream piping of dry/wet pre-action valve assemblies per NFPA standards.

Q5: What do the different colors (obomvu, orange, njll.) on fire fittings indicate?

Colors identify fire system functional zones or hazard warnings. Red is most common for fire sprinkler systems. Orange typically indicates fire pump suction/discharge or wet alarm valve zones. Blue/gray/white are used for special fire systems or per owner/engineering color code specifications. Color does not affect product performance – all are epoxy coated.
