Stuck in a 3-way valve because it is dirty or arid.įor ordinary problems, popping occurs at PSV. If for three-way valve usually replace the internal parts like its o ring, whereas in order to overcome stuck at a three-way valve do greasing of the internal plunger. To this, we can issue leaked retighten the bolts or given a Teflon sealant. It could be leaking at three-way valve components. Commonly Leaking occurred in the connection of nuts on the tubing. The Problems That Often Arise in Wellhead Control Panel (WHCP)įrom the various experiences, The problems that often arise in WHCP are leaking, popping, and stuck. Pneumatic-powered convert hydraulic power can become larger by using the pump. Hydraulic power is used to run the valve actuator which relatively large power needs. by installing the hydraulic pump on run by pneumatic power. With pneumatic power from gas, we can also have hydraulic power, i.e. Later will be discussed where the pneumatic power source to run the WHCP. And generally WHCP from gas wells using gas from the well itself as a source of pneumatic power. Why WHCP generally uses pneumatic control, because most of the well gas wells far location (remote) so hard to find sources of energy such as electricity. WHCP I discuss here is that it uses control pneumatic or hydraulic. But don’t imagine WHCP like PLC in General. So if I can give analogical WHCP is a controller (a control system), SSV, MV, DHSV, SDV are the part that receives the output from the controller, while the PALL, PAHH, fusible plug is the input of the controller. Valves are a part of which will receive command of the signal to be opened or closed from Wellhead control panel.
WHCPs may have multiple applications, which include, but are not limited to
