Petrochemical Industry Online Leak Sealing and Valve Packing Sealing — 55 Thread Sealing Cord Emergency Repair

Project BackgroundA leak occurred at a flange connection of a steam pipeline at a coastal petrochemical enterprise. The pipe diameter was DN200, the medium temperature was approximately 280℃, and the pressure was 1.6MPa. Traditional sealing methods could not complete the repair without shutting down the process.

Core ChallengesFast and effective sealing was required under high-temperature, pressurized, and non-shutdown conditions. The petrochemical environment has stringent requirements for the oil resistance and chemical media corrosion resistance of sealing materials.

SolutionFORWA FW55 Thread Sealing Cord was used for online leak sealing operations. This product is made of special high-strength fibers compounded with sealing adhesive, offering excellent oil resistance, chemical media resistance, and flexibility. It is specifically designed for pressure sealing leak repair, valve packing, and various irregular threaded connections, making it a reliable choice for emergency repair and routine maintenance in petrochemical, marine, energy, and other industries.

Application Results |The leak point was effectively controlled within 30 minutes, avoiding millions of yuan in economic losses caused by unplanned shutdown. The solution was subsequently incorporated into the enterprise's emergency repair standard operating procedures.
