TXY-8# Sealant / Compound For Pipeline

5. When the system temperature is lower than 250 ^oC , the TXY-18#, TXY-16# or TXY-8# sealant could be adopted to seal the leakage. After the injection is completed, the sealant should be replenished for pressing in the correct order so as to avoid the laxation of stress.

4. As for the leakage sealing with high pressure and low temperature, the outer heating method could accelerate the solidification.

3. As for the grain or strong sticky medium sealing leakage, the edges should be set for the clamp to prevent the sealing airproof cavity.

2. The serious leakage parts with high temperature and high pressure should adopt the TXY-18# for sealing, and attention should be paid to the coordination of the drive speed and the solidifying duration.

1. When the valve packing box or high-temperature system flange connection gap is small, for sealing of leakage, the TXY-16# sealant should be adopted.

Applied Reference

The sealant could, under certain pressure and temperature, become deformed and fill airproof cavity.

Model of sealant

Ambient temperature and basic solidifying duration of the sealant

The sealant could, influenced by ambient temperature, shift from the plastic features to the elastomer, which could take some time before forming the tough elastomer.

(3) Pressure-proof performance

It refers that the sealant is, after contacting the medium for a long time, able to resist swelling and solvency.

(2) Medium-resistant performance

In certain time and under certain temperature, the sealant maintain the stable intensity and elasticity.

(1) Temperature-resistant performance, pressure-proof capacity, and basic solidifying duration

(4) Basic solidifying duration

2. Main performance of the sealant
After being pressed, the sealant could endure enough sealing specific pressure.
