UL FM Grooved Mechanical Tee

The UL FM Grooved Mechanical Tee is centered around "dual certification compliance," ensuring it meets both UL's electrical safety, flame resistance, and North American market access requirements, as well as FM's fire resistance and long-term reliability standards by quantifying dimensions, materials, pressure, and sealing performance. When selecting, factors such as main/branch pipe dimensions, medium characteristics (pressure/temperature/corrosiveness), and application scenarios (fire protection/explosion-proof/industrial) must be considered to guarantee "worry-free compliance and outstanding performance" in high-risk global projects.

Product Details

Product Formation

The UL FM Grooved Mechanical Tee is a dual-certified pipe branching component that has earned both UL (Underwriters Laboratories) and FM (FM Global) authoritative certifications. Designed for rapid, weld-free branch connections in high-risk scenarios, it employs grooved mechanical crimping technology at its core. Its saddle structure and elastic sealing assembly ensure secure connections between the main pipe and branch, combining UL's electrical safety and material flame-retardant certifications with FM's fire resistance and long-term reliability approvals. This makes it a premium solution for global piping systems—especially in fire protection and industrial applications—for branch connections.

The UL FM Grooved Mechanical Tee is a combination of "dual international authoritative certifications + grooved mechanical press-fit technology." It has passed UL's electrical safety and flame retardancy tests as well as FM's fire resistance and long-term reliability verifications, achieving "safe and efficient welding-free connections with flexible and reliable full-scenario adaptability." Its core value lies in providing "compliance-worry-free, performance-excellent" branch connection solutions for high-risk global projects (especially in fire protection and industrial sectors), promoting modular, standardized, and international upgrades in pipeline installation. It is the preferred fitting for multinational projects and high-standard endeavors.

Product Features

The UL FM Grooved Mechanical Tee (UL & FM Dual-Certified Grooved Mechanical Tee) builds upon the advantages of FM single certification by adding UL certification for electrical safety, flame resistance, and North American market access, creating a composite advantage of "dual authoritative endorsements + ultimate performance compatibility." Its core features are as follows:

Dual Certification Synergy: Meets FM's long-term performance requirements for fire protection and industrial applications while addressing electrical safety and North American market access challenges through UL, enabling "barrier-free global project applications."
Mechanical Locking: The saddle compression seat is secured with high-strength bolts, with edges embedded into the main pipe groove (or toothed grip), passing UL's "tensile strength test" and FM's "shear force test" to withstand medium pressure and vibration (water hammer effect).
Welding-Free Connection, Eliminating Multiple Risks: No hot work required, avoiding material damage caused by welding (e.g., steel annealing, cast iron cracking). Particularly suitable for flammable and explosive environments (oil/gas stations) and no-fire zones (hospitals, data centers), eliminating fire hazards and hot work permit costs.
On-Site Flexible Modifications, Dynamic Adjustments Without Interruption: Allows direct addition/adjustment of branches on live main pipelines (no need to shut down or cut the main pipe). Simply disassembling bolts completes the process, avoiding traditional "main pipe dismantling-re-welding" large-scale modifications and minimizing system operation impact (ideal for municipal pipelines and industrial continuous production scenarios).
Low Operational Barrier, Standardized Process: Installation relies on standardized tools (torque wrenches, hydraulic hole expanders) and procedures. Bolts are tightened diagonally in stages, and ordinary technicians can operate after training, reducing reliance on professional welders.
