Product details

The gas wellhead is a set of special equipment installed at the wellhead of the gas well, used to hang the oil pipe, seal the wellhead, control the gas well production, ensure safety and facilitate well repair operations.

Product Description
Structural composition: usually composed of tubing head, casing head, valve, flange, seal, etc. The tubing head connects the tubing and casing, used to hang the tubing and seal the annular space between the tubing and the casing; the casing head connects the casing and the main part of the wellhead device, used to support the wellhead device and seal the annular space between the casing and the wellhead device; the valve is used to control the production process of the gas well and safe pressure relief; the flange connects the flange interface of each component of the wellhead device, which is easy to install and disassemble; the seal is used to achieve the sealing between the tubing and the casing, and between each component to prevent fluid leakage.
Main types: According to factors such as wellhead pressure, production, gas composition, etc., it can be divided into ordinary gas wellheads and special wellheads such as high-pressure and high-yield gas wellheads and sulfur-containing gas wellheads. Ordinary gas wellheads are suitable for gas wells with low wellhead pressure and production; high-pressure and high-yield gas wellheads are used for gas wells with high wellhead pressure and high production; sulfur-containing gas wellheads are used for gas wells containing corrosive gases such as hydrogen sulfide, and use anti-sulfur materials and special sealing structures to ensure safe operation.
Product Features
Strong pressure bearing capacity: The wellhead pressure of gas wells is generally much higher than that of oil wells. Gas wellheads need to have a higher pressure bearing capacity to ensure safe and reliable operation under high pressure environments, and can usually withstand pressures of tens of MPa or even higher.
Good sealing performance: Good sealing performance is one of the key features of gas wellheads. By adopting high-quality seals and advanced sealing technologies, such as metal seals and combined seals, natural gas leakage in the well can be effectively prevented, and safety accidents and environmental pollution can be avoided.
Strong corrosion resistance: In some gas wells, natural gas may contain corrosive components such as hydrogen sulfide and carbon dioxide. The material of the gas wellhead is usually corrosion-resistant alloy steel or stainless steel, and anti-corrosion treatment such as coating and lining will also be carried out to extend the service life of the equipment.
Easy to operate: The valves and control components of the gas wellhead are usually designed to be easy to operate, so that operators can easily open and close the well, adjust the production and pressure, etc. In addition, some modern gas wellheads are also equipped with remote control functions, which can realize remote monitoring and operation.
High safety: Equipped with safety components such as safety valves and emergency shut-off valves, these safety components will automatically operate to ensure the safety of the wellhead when the pressure in the well exceeds a certain value or an emergency occurs. At the same time, the design and manufacture of gas wellheads also need to comply with strict safety standards and specifications, such as API Spec 6A.
Adapt to different working conditions: The gas wellhead can be customized according to different well conditions and process requirements. For example, the gas wellhead that adapts to special working conditions such as high temperature, high pressure, and high sulfur content can also be equipped with corresponding heating, insulation, throttling, metering and other functional modules to meet the diversified needs of gas well production.
