Selecting the right sealant is critical to the success of a sealing project as different sealant is designed to meet different requirements of working conditions. Three variables are considered when evaluating the working conditions: working temperature, leaking pressure and leaking media. We have successfully developed various of sealants including TXY-6 series with best performance under low temperature, TXY-16 series with best flowability and TXY-18 series with widest range of media resistance.

Performance
⑴ Temperature-resistant performance, pressure-bearing capacity, and basic curing time

The sealant maintains the strength and elastic stability under certain temperature within a given time.

⑵ Medium-resistant performance

The sealant contacting the medium for a long time has high resistance to swelling and solution.

⑶ Pressure-bearing performance  

The sealant compactly filled could remain sufficient unit sealing load.

⑷ Basic curing time

⑸ Flowability

The sealant could become plastically deformed after fully filling into the sealing cavity under certain pressure and temperature.

Application Reference

⑴TXY-16# is applied in the narrow flange connection gap and valve stuffing box seal.

⑵ TXY-18# is applied in the serious leak system of high pressure and temperature. The attention should be paid to the coordinate the injection speed and the sealant curing time.

⑶ The grooves should set up at the clamp edge for blocking the granular or strong adhesive leaking medium.

⑷ The clamp for the working system of low temperature and high pressure could be heated externally.

⑸ The first round of injection should be followed up by a second round of additional injection to avoid stress relaxation in the sealing cavity in case of the system temperature is below 250℃.
