Wellhead Components

Tubing Head Tubing head is a vital component in the oil and gas industry, enabling the safe and efficient production of hydrocarbons from underground reservoirs. It provides a secure connection for production tubing, controls wellbore pressure, and helps maintain the integrity of the wellhead system. Description The Tubing Head is an adapter between the first casing column and the blowout preventer set (during drilling) or wellhead (after completion). The adapter can be threaded or welded to the casing and can have flanged or clamped connections to match the blowout preventer set or wellhead. It is the primary interface for pressure control equipment. At the time of installation, the casing head is usually tested for very stringent pressure and leakage parameters prior to the installation of any surface equipment to ensure viability under blowout conditions. Characteristics The tubing head and tubing cross are used to suspend the tubing and seal the annular space of tubing. Its characteristics are: 1. The secondary sealing form between the tubing hanging and the reducer flange includes O-ring seal, greased BT seal and metal-to-metal seal; 2. The sealing forms of tubing hanging and tubing head are metal-metal seal, special synthetic rubber seal or metal seal + special synthetic rubber seal; 3. With grease injection port and sealed test port; 4. The lower sealing form of the tubing head includes O-ring seal, greased BT seal and metal seal; 5. The tubing hanging and tubing head reducer flange can directly pass through the cable and can be equipped with a downhole safety valve control pipeline interface; 6.The side exit link is threaded or wire-flange type, and is equipped with VR thread for easy valve replacement operation.

Surface safety valves (SSVs) are essential safety devices used in oil and gas production systems to prevent the uncontrolled release of hydrocarbons from the wellhead. They are designed to automatically shut off the flow of oil and gas in the event of an emergency, such as a blowout or equipment failure. SSVs are typically installed on the wellhead, and they are activated by a remote control system located at the surface. When the control system detects a potential safety hazard, it sends a signal to the SSV to close, which stops the flow of oil and gas from the well. This helps to prevent the release of hydrocarbons into the environment, which can have serious environmental and safety consequences. Design Details SSVs come in a variety of designs, but they all share the same basic components, including a valve body, actuator, and control system. The valve body is the main component of the SSV, and it contains a gate or ball valve that can be opened or closed to control the flow of oil and gas. The actuator is responsible for moving the valve, and it is typically powered by hydraulic, pneumatic, or electric systems. The control system monitors the wellhead for potential safety hazards and sends signals to the actuator to activate the SSV when necessary. The surface safety valve is an important component of wellhead production. When high pressure enters the drive, the bottom spring will open the valve. Through console operation, the spring on the relief valve will automatically push the stem to close the valve, thus ensuring the safety of the production. assembled safety valve with consideration of optimal safety and economics. The available safety valve sizes are from 1-13/16" through to 7-1/16", with pressure ratings from 2000psi to 20000psi.
