On-Line Leak Sealing (OLS) is a maintenance technology that seals leaks under the operating pressure and temperature, and flow rapidly and reliably without production shutdown. This service involve:

Clamp Design

Clamp material selection and clamp structure design are critical for successful leak sealing operation. By taking online leaking process physical conditions into account, stress analysis and calculation are rendered to ensure a pressure/temperature-resistible clamp structure. The TXY-Tech’s unique clamp provides connections between an injection gun and the clamp cavity for the sealant to be optimally injected. Meanwhile, the shape (geometry) of a clamp varies depending on the location of leaking piping or equipment.


Invented by TXY-Tech’s founders, the TXY serial and universal sealants enjoy the quality of covering wide range of low/high temperature. (From cryogenic to 1472 F), low/high pressure (from vacuum to 4641 psi) and wide process medium resistance. Years of research and development on sealants by TXY have considerably contributed to sealant diversification applicable to a wide range of leaking conditions. Recently, we further developed sealant products for moving parts (such as valve stem) application.
