Pressure-on Valve Change technology make use of special equipment and techniques, to separate the high-pressure oil-gas inside the wellhead (pipe) with the atmosphere. And then we drill, change control valves and so on.
The technology has overcome the disadvantage of traditional killing process. Its low-cost, short-time, energy-saving, emission reduction, safe, pollution-free, the oil (gas) wells serviceable life extension and so on. Its a great revolution in the history.
Advantage:
Cost-effective
the Effective Protection of Oil and Gas Resources
Avoid Environmental Pollution

Technology Theory:
Slipping down the hydraulic plug tool to front channel of gate valve (inside of tubing or side path of tubing head spool), do hydraulic anchoring and sealing, reduce the pressure outside of hydraulic plug tool to zero, and then change 1#, 2#, 3# main control valve.
Operating Process:
path checking by path gauge→ tube scraping by tube scraper→ slipping in plug tool→ seat sealing observation→ valve changing→ unsealing→ withdraw the tool.
Working Theory:
transfer device
1# control valve
Plug tool of tubing/tubing plug
2# main valve
Plug tool of casing
3# main valve
