Description

[Detailed Description of the Invention] The present invention provides a method for sealing from the inside of a tank in order to prevent leakage at pipe joints during the inner surface treatment process for water pipes, gas pipes, etc. ↑Sealing 1 of 11f section
2 people (Koseki - 4 people.

When drying the supplied gas using the C1 high-medium 11-bar feeding method in existing gas piping, the sealing material at the pipe joints may turn into fine dust and scatter into the gas, causing leakage1.
As a method of repairing the above-mentioned pipe joint part while it is buried, it is known to use the pipe inner surface TI-4 agent as a seal (Δ) on the pipe joint part. However, the paint film is thin /, = Me, the joint part is not strong enough to maintain the condition. ,stomach)
Although the membrane is 17 times thicker, it does not have the effect of reinforcing the 4F sealing material in a coarsely filled state and preventing leakage.5. In this case, the sealing layer and the lining layer are not substantially integrated, and cracks occur in the lining layer from this point.
There is a risk of damage and leakage during the semester.

The present invention has been made based on the above circumstances (b), and therefore the pipe t (Jl'

Sealing for pipe joints that penetrates into the pipe joint and hardens to increase the density J3 and strength of the seal material, thereby reliably preventing cracks, damage, and leakage from the pipe joint. The aim is to provide construction methods.

For this purpose, a VIG of λ·1 whose circumferential surface moves in airtight contact with the inner wall surface of the pipe is installed inside the IA of the present invention + J, , rk, and a VIG of another Puno is placed in each of the two pigs. At 12, the curvature extending from t to the vertical part of the body is ml-', and f is 1.

In this case, according to the present invention, there is a LI theory that the cause of leakage is caused by the opening of the pipe. - By penetrating the sealant into the sealing material and solidifying it, it increases the strength of the seal and prevents leakage from the surface. It actually prevents damage.
