Abstract

The invention discloses an apparatus for application of corrosion control compounds into pipe flanges 10 comprising a pressure generator unit 15, an injection unit 20 and a flange belt 25. The pressure generator unit 15 is configured to supply pressure to the injection unit 20 that communicates to said pressure generator unit 15. The injection unit 20 comprising a corrosion control compound chamber 60 configured to contain corrosion control compound wherein the corrosion control compound is driven out of the corrosion control compound chamber 60 via an outlet 75 arranged on a closure 70 of the corrosion control compound chamber 60 into a delivering tube 30 and toward the flange belt 25 assembled onto a pipe flanges where the corrosion control compound is manipulated to fill flange gaps at the said pipe flange.

Claims

1. An apparatus for application of corrosion control compounds into flange gaps (10) comprising:
a pressure generator unit (15);
an injection unit (20); and
a flange belt (25);
wherein the pressure generator unit (15) is configured to supply pressure to the injection unit (20) that communicates to said pressure generator unit (15);
the injection unit (20) comprising a hydraulic cylinder (55) which communicates to a corrosion control compound chamber (60) configured to contain corrosion control compound; said corrosion control compound chamber (60) is assembled onto a support plate (110) of which capable of moving along the length of a first brace (115) and a second brace (116) of which the support plate (110) is assembled thereon;
wherein a piston (61) including a piston rod (65) arranged inside the hydraulic cylinder (55) pushes against the support plate (110) including the corrosion control compound chamber (60) assembled thereon to move toward a stationary closure (70) having an outlet (75) and being suspended from an end plate (120) arranged at a distal end of the first brace (115) and the second brace (116) and drives the corrosion control compound out of the corrosion control compound chamber (60) via the outlet (75) arranged on the closure (70) of the corrosion control compound chamber (60) into a delivering tube (30) and toward the flange belt (25) assembled onto a pipe flanges where the corrosion control compound is manipulated to fill flange gaps at said pipe flange.
2. The apparatus (10) according to claim 1, wherein the flange belt (25) being a substantially ring shape with adjustable circumference; said flange belt (25) comprising a plurality of injection ports (26) distributed to spaced-apart evenly along the circumference of the flange belt (25); each of said injection port (26) includes a through hole (29) which receives the corrosion control compound from an end of the delivering tube (30) coupled to said injection port (26).
3. The apparatus (10) according to claim 2, wherein the pressure generator unit (15) is an air-to- hydraulic pressure booster system (85) comprising an air-hydraulic pump (90) and a compressor (95) supplying compressed air to said air-hydraulic pump (90).
4. The apparatus (10) according to claim 2, wherein the flange belt (25) is lined with a rubber pad (27) along an inner surface of the flange belt (25).
5. The apparatus (10) according to claim 4, further comprising a base (80); said base (80) being a mobile base wherein the pressure generator unit (15) and the injection unit (20) are installed on said base (80).
