U-bolt replaces cover part, without welding, directly from the main pipe branch.
The U Bolt Mechanical Tee is specifically designed for pressurized pipe branching without the need to cut or shut down the system. Using U-bolt locking technology, it directly connects the main pipe and branch pipes. Suitable for fire protection, petrochemicals, industrial water supply, and drainage systems, it can be deployed in 30 minutes, significantly reducing construction risks and costs.
No Shutdown Installation: Unique U-bolt and saddle structure allows pressurized operation without affecting the main system's operation.
Rapid Construction: No cutting or welding required; a single person with a toolkit can complete branch connections in 30 minutes.
High Pressure Resistance: High-strength forged steel body with fully enclosed rubber gaskets offers pressure resistance from Class 150 to 300 and excellent vibration and displacement resistance.
Zero Leakage Sealing: Triple protection (U-bolt preload + EPDM sealing ring + saddle groove) suitable for water, oil, and gas media.
Flexible Adaptability: Supports steel pipes, ductile iron pipes, and HDPE pipes (with optional bushings), covering diameters from DN50 to DN400.
Fire Protection Network Renovation: Quickly add sprinkler branch pipes without draining the main water supply.
Petrochemical Pipeline Expansion: Add inspection or diversion ports under pressure for oil/gas pipelines.
Building Emergency Repairs: Bypass damaged pipes to avoid water or gas shutdowns.
Municipal Water Supply Systems: Upgrade aging pipelines by adding new branches without shutting off water.
Material: Main body ASTM A105 forged steel / EPDM rubber seal (optional fluorine rubber for oil resistance).
Pressure Rating: Class 150/300 (static pressure ≤ 2.5MPa).
Operating Temperature: -30°C to 120°C (EPDM) / -20°C to 150°C (fluorine rubber).
International Certifications: FM/UL fire safety certification, ISO 9001, API 6A.

Will the U-bolt corrode the pipe? Galvanized bolts with nylon washers prevent metal contact corrosion and have passed a 5-year salt spray test.
Can the branch angle be adjusted? Supports vertical (90°) and horizontal diversion with 360° directional adjustment of the branch on-site.
How to install on HDPE pipes? Equipped with stainless steel reinforcing bushings to prevent plastic deformation, increasing pressure resistance by 40%.
