Product Formation

Engineered for reliability and compliance in critical fire safety applications, the UL/FM Approved Grooved 45° Elbow stands as a premium piping fitting designed to optimize fluid flow and ensure secure connections in fire protection systems worldwide. Crafted with precision using ductile iron (ASTM A536 Grade 65-45-12), this elbow delivers exceptional strength, corrosion resistance, and durability—even in harsh operating environments ranging from -29°C to 121°C (-20°F to 250°F).

Certified to meet UL 213 and FM 1921 standards, alongside ANSI/AWWA C606 grooved connection requirements, the fitting guarantees full compliance with European, American, and global fire safety regulations, making it the ideal choice for export projects, commercial buildings, industrial facilities, and infrastructure developments. Its 45° precision angle design minimizes pressure drop and fluid turbulence, ensuring efficient water distribution in sprinkler systems, hydrant networks, and fire suppression pipelines.

Product Features

1.Authoritative Compliance for Global Projects:

Certified to UL 213, FM 1921, and ANSI/AWWA C606 standards, fully meeting fire engineering acceptance requirements in Europe, America, and other international markets. Optional CCCF certification available for dual domestic and overseas project compatibility. Backed by quality insurance from leading insurers for enhanced reliability.

2.Superior Durability & Corrosion/Pressure Resistance:

·High-Strength Material:Ductile iron with tensile strength ≥500MPa and elongation ≥15%, resisting pressure impacts in fire piping systems.

·Comprehensive Anti-Corrosion:Epoxy coating or hot-dip galvanization on the surface ensures resistance to weak acids, alkalis, and weathering. Zinc-plated bolts/nuts meet grade-specific mechanical standards, preventing rust and breakage.

·Reliable High-Pressure Sealing:Equipped with standard-compliant gaskets for leak-proof performance even after repeated disassembly. Withstands maximum working pressure of 300PSI for high-pressure fire pipelines.

3.Efficient,Safe & Easy Installation:

Grooved connection eliminates welding and complex threading. Requires only basic tools and minimal training for operators. Avoids fire hazards from open flames and clogging of sprinklers by weld slag. Installation efficiency is significantly higher than traditional welding, with convenient disassembly for future maintenance, reducing labor and time costs.

4.PRECISE Adaptability for Multi-Scenario Applications:

High Structural Precision:45° angle processed with precision minimizes fluid resistance and turbulence, ensuring efficient water flow.
Full Specification Coverage:Available in DN25-DN600 sizes, compatible with mainstream fire pipes for diverse project needs.
Flexible Connection:Accommodates minor pipe deflection and compensates for thermal expansion/contraction or building settlement, reducing vibration and noise.

5.Exquisite Craftsmanship & Safety Assurance:

Manufactured via automatic DISA casting lines for dense internal structure, free of sand holes or inclusions. Bolts undergo ultrasonic flaw detection to prevent breakage. Flame-retardant gaskets meet fire safety standards. Black wire processing option avoids paint peeling and sprinkler clogging, minimizing safety risks.
