Product Overview: A rapid repair device specifically designed for sudden leaks at pipeline flange connections and tees. Utilizing a high-strength saddle-shaped structure, it achieves permanent sealing of leak points under pressure without shutting down pipelines or requiring open flames. It is an essential solution for emergency repairs in industries such as petrochemicals, municipal water supply, and energy and power.
Core Technological Advantages
• Three-Dimensional Adaptive Sealing: Built-in special oil-resistant rubber sealing ring, combined with a patented arc-shaped saddle pressure plate, automatically compensates for irregular pipeline deformation and corrosion pits, forming a 360° surround pressure self-tightening seal.
• Split-Type Quick-Installation Design: Employing a split hinge structure, installation can be completed by a single person within 10 minutes. Bolt preload is optimized through mathematical modeling to ensure uniform stress at all points and avoid localized overload.
• Comprehensive Coverage: Unique modular design allows one product to perfectly adapt to various leak types, including flange sealing surface leaks, tee weld cracks, and pipe corrosion perforation, covering pipe diameters from DN50 to DN600. • Military-grade materials: The main body is made of QT450-10 ductile iron or 304 stainless steel precision casting, with key bolts made of 35CrMo alloy steel. The pressure resistance rating reaches PN4.0MPa, suitable for extreme environments from -50℃ to 300℃.
Core application scenarios:
▶ Petrochemical energy: Oil and gas leaks at flanges and pump/valve connections in oil/gas pipelines.
▶ Urban lifeline: Emergency repairs of tees and elbows on main water and heating pipelines while the pipeline is submerged.
▶ Industrial operation and maintenance: Rapid sealing of pinholes in welds of steam and chemical media pipelines in factories.
▶ Emergency response: Emergency handling of pipeline leaks caused by natural disasters or accidents.
Performance Certification
Sealing Pressure: Up to 4.0MPa (static) / 2.5MPa (dynamic fluctuation)
Fire Resistance Certification: Flame-retardant sealing material is available, passing GA/T 537 standard testing.
Long-Term Verification: Accelerated aging simulation tests confirm a seal life exceeding 10 years.
Standardized Operating Procedures
Preparation: Clean the anti-corrosion layer and debris around the leak point; measure and record the pipe outer diameter and leak size.
Quick Installation: Align the seal with the leak point, close the upper and lower housings, and pre-tighten the bolts diagonally.
Pressure Injection: Inject the special sealant into the sealing cavity through the standard grease injection valve until pressure equalization.
Final Tightening: Tighten all bolts to the calculated torque value (torque wrench included with the product).
