Other Flow-Control Devices

Most of the flow control functions are described in this chapter in Sections on Wellheads and closing systems Safety and chapters. 11 to 16. Some valves and controls are discussed in chapters. 4 (Packers production) and 5 (Gasfeder). Other flow control devices are discussed in the following. Technical Data used in the field explained in petroleum courses in Rawalpindi.

they do not obstruct the flow through the tube ein. Sidepocket- mandrel valves can be removed by fixed line for the repair of the Boards, which are subject to damage when you first open the flow path. Sliding sleeve valves can be equipped with landing nipple profiles for insulation with a locking mandrel fixed in case of seal failure. The sliding sleeve valves can be incorporated into the nipples for Safety valve to isolate the control line when the safety valve is removed. Some more details of petroleum courses in rawalpindi are as under

The tube must be connected to prevent flow or loss of control when the shaft and / or master valve is to be removed. The plugs are available for landing nipples in the wellhead and nipples in the pipe string. tube caps are set and retrieved using the methods fixed line.
The chemical injection valves
Some wells require frequent or continuous injection of small amounts of chemicals, such as methanol, for freeze protection or as inhibitors to corrosion Steuer products. The chemicals can be injected through a tube ein small diameter parallel through the annulus or tube ein / casing. injection valves chemicals can be installed on a circulator to better control the injection speed and to provide protection against backflow.
Safety valves input (ISV)
Injection wells may be protected by security closure systems discussed in this chapter. The ISV is a safety valve low cost that can be used for wells where only Heu flow down into the Pit. It is basically a holding valve mounted on a mandrel fixed telephony recoverable located in a landing nipple. The upflow valve closes.
Aspects wellhead corrosion
Corrosion ein often defined as the destruction of a Metall by reactions with its surroundings. The attack may be internal or external and can result from chemical or electrochemical action.
internal attack is usually a result of corrosion weight loss ( "Sweet Corrosion") caused by the presence of organic acids CO * and either sulfur or cracking chloride stress corrosion ( "Corrosion ACIDA") caused by the presence of HzS. chlorides, or combination of these elements. external attack is generally "Corrosion oxygen" caused by exposure to atmospheric oxygen, electrochemical Corrosion "caused by the flow of electrical currents or a combination of the two.
One or more methods may be employed to control corrosion in equipment wellhead, depending on the type of corrosion present and the costs of processes: (1) the use of special corrosion resistant alloys, (2) injection an effective inhibitor, (3) the implementation of effective coatings, and / or (4) properly implemented and maintained cathodic protection. Although a detailed discussion of the Corrosion is
is not the purpose of this section, it is necessary to briefly describe the various types of corrosion found in wellhead equipment to explain the various methods Kontrolle. internal and external corrosion Sohn controlled differently and are treated separately.

Flow Control Devices: Safety Shut-In Systems

Since the consequences of uncontrolled flow Pesos graves son tanning, especially offshore, well Automatic Closing Systems Security son sufficiently important that sometimes required by law child. 6 Systems belts must be failsafe. The failure of the energy source or any component should cause the system to go to Safe Mode. Usually Safe Mode MEAN wells are closed at one or more points. The Security Systems detect conditions in the lease or platform and close the well or wells WHEN the conditions of the preset limits are diverted. Technical Data used in the field explained in petroleum courses in Rawalpindi.

Closing in the well prevents damage DUE ADDITIONAL one (1) the uncontrolled flow break
Pressure vessels, (2) Feeding any fire that started or can be started, or (3) cups too full of fluid

Some adj systems may be contained in a single valve or can be very large multiwell multivalve, multiparameter, Integrated Systems multilogic In a Production Control System telemetry. Severity of the consequences generally dictates what How to make Security System Dębe be. Safety valves may be located in the pipe string [Valve Security Fund (SSSV)], in the Christmas tree, or downstream of the well in the (safety valve surface) train process (Figs . 3.6 and 3.7). Most Valves: safety are controlled by externally applied fluid pressure. Liberation Pressure control allows the valve to close itself.

Surface Safety Valves (SSV)

A SSV in the Christmas tree is usually the second valve in the flow stream. So is the second master valve, if the vertical stroke, otherwise, is a butterfly valve. SSV can be located downstream of the well on the train Process tales Places of Como (1) header flowline (2) suction, discharge and bypass compressor UN (the safety valve bypass Safe mode Place open closed) esta, or (3) at the entrance to the sales pipeline or pipeline Leaving a platform.

API Flanged or Clamped Wellhead Equipment under free online training of petroleum courses in Rawalpindi

The maximum operating pressure is the maximum pressure on the equipment to be used. The hydrostatic test pressure is to ensure the static pressure testing a safety margin above the nominal working pressure body. The test pressure is to demonstrate the manufacturer imposed competence in design, materials and workmanship of the body part or the housing and It should not be used as a differential pressure across packer mechanisms internal or suspension closing mechanisms. Occasionally the wellhead equipment and valves will accidentally or intentionally exposed at higher pressures design work for the repair of high-pressure press. Although often the team can withstand abuse, these practices should be avoided. Technical Data used in the field explained in petroleum courses in rawalpindi.

All manufacturers promote their safety factors based on sound engineering and product experience from the past, but the stresses caused by vibration, shock and temperature variations are not predict. The equipment should never be subjected to pressures above the recommended working pressure. If for any reason, the equipment is used in unusually high or extreme Working pressure, insist the manufacturer that a disclaimer clause be written and correctly formulated the legal liability to relieve. The disclaimer should be possible to show results, expected due to equipment failure. Table 3.1 shows the values ​​of the operating pressure of the standard API, and their respective test pressures body. Some more details of petroleum courses in rawalpindi are as under

Given the complex in the sealing threaded connections, high pressure mechanisms is that field devices are advised properly and API RP 5CL followed are monitored for lubricants with respect, make-up etc. of discussions API. "The working pressure mounted properly screw a wellhead component or flowline and a tubular element often combines the review of the tubular member is determined. In this case, the maximum operating pressure of the terminal when the pressure of the inner deformation taken in the minimum yield, as in the Bull API set. SC2 for the size and type of yarn and the weight and the degree of tube or housing, by an appropriate safety factor is reduced particularly. " However, this review must not not exceed the maximum operating pressure.
