The operational details of the invention with reference to the Figure 1 to 16 are as under:
OPERATIONAL DETAILS
The following steps have to be followed for sealant or semisolid compound or cold weld compound removal from sealant stick (Figure-3) by "PNEUMATIC SEALANT STICK ADAPTER" and inject into high pressure leaking valve or pipe line by hydraulic pressure, using high pressure hydraulic cylinder (Figure-5) or pressure intensifier (Figure-6).
1) At "PNEUMATIC SEALANT STICK ADAPTER", three way selector valve has to be selected to vent line (Figure-2 No.4). Sealant stick (Figure-3) has to be inserted into sealant stick barrel (Figure-4). Piston seal assembly (Figure-2) with piston (Figure-1) has to be latched with sealant stick barrel and cam lock (Figure-4 No.1) has to be closed this gives the air tight sealing between, male(Figure-2 No.6) and female cam lock coupling(Figure-4 No.1), sealant stick (Figure-3) and piston(Figure-l) and sealant stick (Figure-3) with sealant stick barrel(Figure-4).
2) At the hydraulic piston cylinder (Figure-5) or pressure intensifier (Figure-6) arrangement the following valves has to be in closed, isolation ball valve (Figure-5 No.8) from "PNEUMATIC SEALANT STICK ADAPTER", isolation ball valve (Figure-5 No.9) for sealant or semisolid compound or cold weld compound inlet to hydraulic cylinder(Figure-5 No.4) or pressure intensifier (Figure-6 No.5) and isolation ball valve(Figure-5 No. 10) to the valve where sealant has to be injected. At hydraulic piston cylinder, hydraulic line three way valve has to be selected to hydraulic oil reservoir (Figure-5 No.5&7) or at pressure intensifier hydraulic pressure equalisation valve (Figure-6 No.6) has to be opened .
3) After ensuring steps 1&2, "PNEUMATIC SEALANT STICK ADAPTER" has to be latched to hydraulic piston cylinder arrangement or pressure intensifier, by connecting female cam lock connector at hydraulic piston cylinder arrangement end (Figure-5 No.1) or pressure intensifier end(Figure-6 No.1), with male cam



lock connector at "PNEUMATIC SEALANT STICK ADAPTER" end ( Figure-4 No.7).
4) After ensuring steps 1.2&3 sealant injection into the leaking high pressure valve can be carried out in two stages.
5) First stage involves injection of sealant or semisolid compound or cold weld compound into the hydraulic cylinder (Figure-5 No.4) or pressure intensifier (Figure-6 No.5) by "PNEUMATIC SEALANT STICK ADAPTER" using pneumatic pressure (Figure-2 No.2), with the following sequence.
a. Isolation ball valve (Figure-5 No.8) from "PNEUMATIC SEALANT STICK
ADAPTER" has to be opened.
b. Isolation ball valve (Figure-5 No.9) for sealant or semisolid compound or
cold weld compound inlet to hydraulic cylinder(Figure-5 No.4) or pressure
intensifier cylinder (Figure-6 No.5) has to be opened.
c. And three way selector valve has to be selected to pressure source (Figure-
2 No.2).
Sealant semisolid compound or cold weld compound get injected into hydraulic cylinder (Figure-5 No.4) or pressure intensifier cylinder (Figure-6 No.5). This can be ensured by inward movement of "PNEUMATIC SEALANT STICK ADAPTER" piston (Figure-1 No.5). In case of hydraulic cylinder arrangement, this can be ensured by outward movement of hydraulic piston(Figure-5 No.4). In case pressure intensifier no visible observation at the pressure intensifier end can be seen as the pressure intensifier piston is not projecting outside.
6) Second stage involves injection of sealant or semisolid compound or cold weld
compound into high pressure leaking valve or pipe line from hydraulic cylinder
(Figure-5 No.4) or pressure intensifier cylinder (Figure-6 No.5) using hydraulic
pressure source (Figure-5 No.6 and Figure-6 No.4), with the following
sequence.
a. Isolation ball valve (Figure-5 No.8) from "PNEUMATIC SEALANT STICK ADAPTER" has to be closed

b. Isolation ball valve (Figure-5 No.9) from hydraulic cylinder(Figure-5 No.4) or
pressure intensifier cylinder (Figure-6 No.5) has to be opened
c. Hydraulic piston cylinder arrangement three way valve has to be selected to
hydraulic power source (Figure-5 No.5&6).
d. At pressure intensifier hydraulic pressure equalisation valve (Figure-6 No.6)
has to be in closed and hydraulic power source has to be supplied at the
rear end of pressure intensifier.
e. Isolation ball valve to the valve or pipe line where sealant or semisolid
compound or cold weld compound to be injected has to be opened (Figure-5
No. 10).
Sealant or semisolid compound or cold weld compound get injected into high pressure leaking valve or pipe line. This can be ensured by inward movement of hydraulic piston(Figure-5 No.4). In case pressure intensifier hydraulic oil comes out at the forward end of the pressure intensifier indicating discharge stroke of the pressure intensifier. And isolation ball valve(Figure-5 No. 10) to the valve where sealant has to be injected has to be opened. .
7) "PNEUMATIC SEALANT STICK ADAPTER" pneumatic pressure venting and
hydraulic pressure bleed off:
a) After ensuring all the three isolation ball valves (Figure-5 No.8,9&10) in closed condition. By selecting pneumatic three way valve of "PNEUMATIC SEALANT STICK ADAPTER" to vent line (Figure-2 No.4), pressure inside "PNEUMATIC SEALANT STICK ADAPTER" can be depressurised. By selecting hydraulic piston cylinder assembly three way valve to bleed port (Figure-5 No.6), hydraulic pressure inside the hydraulic piston cylinder assembly can be depressurised. At pressure intensifier, hydraulic pressure equalisation valve (Figure-6 No.6) has to be opened
8) Dismantling of "PNEUMATIC SEALANT STICK ADAPTER" (Figure-13).
a. After ensuring step 7, Cam lock at sealant stick barrel end (Figure-4 No.1) has to be opened. By removing male cam lock (Figure-2 No.6) attached with piston seal assembly (Figure-2) from Cam lock at sealant stick barrel end


(Figure-4 No.1), piston seal assembly (Figure-2), piston (Figure-1) and sealant stick (Figure-3) can be removed together from sealant stick barrel..
9) Removal of hydraulic piston cylinder assembly (Figure-14) or pressure intensifier (Figure-15) from "PNEUMATIC SEALANT STICK ADAPTER".
a. After ensuring step 7, hydraulic pressure inside the hydraulic cylinder (Figure-5 No.4) depressurised, cam lock (Figure-5 No.1) at the hydraulic piston cylinder (Figure-5 No.7) or pressure intensifier (Figure-6 No.1) has to be opened and the hydraulic piston cylinder assembly (Figure-5) or pressure intensifier (Figure-6) can be detached from "PNEUMATIC SEALANT STICK ADAPTER".
io) The above procedures have to be repeated for every sealant stick.
Although the present invention has been described in detail, those skilled in the art should understand that they can make various changes , substitutions and alterations herein without departing the spirit and scope of the invention in its broadest form.
