Wellhead and Christmas Tree

Wellhead Christmas Tree Manufacturer | HRSB

Rongsheng stands as a leading provider of comprehensive solutions in the oil and gas industry, offering a range of Wellhead and Christmas Tree equipment engineered to meet the highest standards of quality and performance.

Our Wellhead systems serve as the primary interface between the surface and the wellbore, providing essential support and control for drilling and production operations. Engineered with precision and durability in mind, Rongsheng's Wellhead equipment ensures reliable pressure containment and optimal well integrity, even in the most challenging offshore environments.

Complementing our Wellhead offerings, Rongsheng's Christmas Tree equipment serves as the control hub for regulating the flow of hydrocarbons during production. From valve assemblies to choke systems, our Christmas Trees are designed with advanced technologies to provide precise flow control and maximize production efficiency.

Backed by extensive industry experience and a commitment to innovation, Rongsheng delivers Wellhead and Christmas Tree solutions that meet the unique needs of each project. Whether for onshore or offshore applications, our equipment is trusted by operators worldwide for its reliability, durability, and performance.

Partner with Rongsheng for your Wellhead and Christmas Tree needs, and experience the difference in quality, reliability, and service excellence that sets us apart in the oil and gas industry.

Welcome to discuss your project!

Difference Between Wellhead And Christmas Tree

The wellhead and Christmas tree are both critical components in oil and gas drilling and production operations, but they serve different functions and are located at different points along the wellbore.


The wellhead is installed at the surface of the well and provides the primary mechanical and pressure containment interface for the drilling and production equipment.

It consists of various components, including casing heads, tubing heads, and casing spools, which are installed to support and control the well casing and tubing strings.

The main function of the wellhead is to provide a secure anchor point for the blowout preventer (BOP) stack during drilling and to contain well pressure during production.

Christmas Tree:

The Christmas tree is located on top of the wellhead and serves as the primary control interface for regulating the flow of oil or gas from the well.

It consists of valves, chokes, and other equipment that allow operators to control the flow of fluids into and out of the well.

The Christmas tree is typically installed after drilling operations are completed and serves as the primary interface for production operations.

In summary, while the wellhead provides the structural support and pressure containment for the well, the Christmas tree serves as the control interface for regulating the flow of fluids during production. Both are essential components in oil and gas drilling and production operations, working together to ensure safe and efficient well operations.

Choose blowout preventer

The main factors to consider in selecting a hydraulic blowout preventer combination are well type, formation pressure, casing size, formation fluid type, personnel technical status, technological requirements, climate impact, traffic conditions, material supply status, environmental protection requirements, and so on. In short, it should achieve balanced drilling, ensure drilling safety, and save drilling costs.

1) Pressure Level

The working pressure of the hydraulic blowout preventer combination depends on the internal pressure resistance of the casing used, the fracture pressure of the open-hole formation at the casing shoe, and the expected maximum wellhead pressure. However, it is mainly determined according to the maximum wellhead pressure that the blowout preventer combination is expected to withstand. There are five types of blowout preventer pressure levels: 14MPa, 21MPa, 35MPa, 70MPa, 105MPa, and 140MPa.

2) Diameter

The diameter of the blowout preventer combination depends on the casing size in the wellbore structure design; that is, it must be slightly larger than the outer diameter of the connected casing. There are nine kinds of BOP diameters: 180mm, 230mm, 280mm, 346mm, 426mm, 476mm, 528mm, 540mm, and 680mm. 230mm, 280mm, 346mm, and 540mm are commonly used on site.

3) Combination Form

The choice of combination form is mainly based on formation pressure, drilling process requirements, drilling tool structure, and equipment supporting conditions.
