Product Definition: A professional pipeline repair engineering solution, employing a high-strength sleeve-type structural design, suitable for repairing external corrosion, cracks, or mechanical damage to oil, natural gas, water supply, and chemical pipelines. No need to shut down operations or perform any work involving open flames; achieves permanent repair by integrating pipeline structural reinforcement and sealing.
Core Technological Advantages
• Double-Layer Composite Sealing Technology: Innovative inner and outer double-sealing layer design: the inner layer is made of media-resistant special rubber, and the outer layer is made of high-performance polymer sealant. Under the action of bolt pre-tightening force, an active pressure-compensating seal is formed, capable of withstanding pressures up to 10MPa.
• Structural Reinforcement Design: Adopts a sandwich structure conforming to ASME PCC-2 standards: the outer carbon steel shell provides mechanical strength, the middle composite filler layer absorbs stress, and the inner anti-corrosion gasket isolates the media.
• Adaptive Pipe Diameter Technology: Patented hinge connection combined with an adjusting shim system can adapt to pipe outer diameter tolerances of ±3%, perfectly fitting various pipe curved surfaces.
