Produktöversikt

De grooved ductile iron fire protection equal tee is a critical fitting used in fire sprinkler and water supply systems for branching, intersecting, or transitioning pipe diameters. Available in both equal and reducing configurations, the product supports both grooved and threaded connection methods to accommodate diverse installation requirements.

Constructed from high-strength, tough ductile iron (ASTM A536), the fitting is certified to rigorous international fire safety standards—including FM (Factory Mutual) and UL (Underwriters Laboratories)—and boasts a pressure rating of 300 psi, ensuring exceptional reliability in critical fire protection applications. Surface finish options include painting, epoxy coating, galvanizing, and Dacromet coating to meet various corrosion resistance specifications. Through precision casting and strict quality control, these fittings are widely utilized in fire sprinkler and water systems for high-rise buildings, commercial complexes, industrial facilities, and warehouses.

Nyckelfunktioner

◆ Ductile Iron Material – High Strength & Toughness
Premium ductile iron (ASTM A536) with excellent tensile strength and elongation, combining cast iron’s pressure resistance with steel’s toughness, effectively resisting water hammer shocks and mechanical vibration for long-term reliable fire system operation.

◆ FM/UL Dual Certified – Global Acceptance in Fire Protection
FM and UL certified, meeting the world’s strictest fire protection product standards – ready for use in fire engineering projects in Europe, America and beyond.

◆ Equal/Reducing Options for Flexible Pipeline Branching
Available in Equal Tee and Reducing Tee – equal tee for same-diameter branch/joining, reducing tee for branch reduction from main line – flexible adaptation to various fire pipeline designs.

◆ Grooved/Threaded Dual Connections for Flexible Installation
Supports both grooved mechanical coupling and threaded connections – grooved for fast installation without hot work, threaded for small-diameter and traditional fire systems – users can choose based on site conditions.

◆ Multiple Surface Finishes for Long Corrosion Resistance
Painted, epoxy coated, galvanized and Dacromet finishes available – effectively resisting salt spray, moisture and chemical corrosion, significantly extending service life for various fire protection environments.

FAQ

Q1: How to choose between equal and reducing tees for fire systems?

Equal tee has three identical openings for same-diameter pipe branches/junctions, ensuring balanced flow distribution. Reducing tee has branch smaller than main run for drawing smaller branch lines from large trunk lines. Selection follows branch pipe diameters per design drawings.

Q2: How to choose between grooved and threaded connections?

Grooved connection installs fast (no hot work), offers good seismic resistance and easy future modification – suitable for DN50 and above. Threaded connection suits DN50 and below small diameters, simple installation, common in traditional fire systems. Both meet fire system requirements – selection depends on design codes and site conditions.

Q3: What is the difference between ductile iron and cast iron fire fittings?

Ductile iron (ASTM A536) offers far superior tensile strength and elongation than gray cast iron, with stronger water hammer and fracture resistance – the specified material for FM/UL certified fire fittings. Cast iron is brittle with poor impact resistance, unsuitable for high-pressure fire systems.

Q4: What fire systems is the 300Psi pressure rating suitable for?

300Psi (approx. 2.1MPa) covers NFPA standard fire system pressure ranges – typical applications include high-rise building fire risers, fire pump discharge sections, and dry/wet sprinkler system mains – meeting the vast majority of building fire water system requirements.

F5: How to select surface finish options?

Painted and epoxy coated are standard options – epoxy offers stronger adhesion and better corrosion resistance, recommended for humid or outdoor environments. Galvanized suits indoor dry conditions. Dacromet provides high-performance anti-corrosion with excellent salt spray resistance for marine environments or highly corrosive locations.
