In the oil and gas industry, the safety of key equipment such as throttling and well-killing manifolds is of vital importance. Especially in high-pressure environments, these equipment need to withstand huge pressures and stably transport oil and gas mixtures containing hydrogen sulfide (H₂S) and other dangerous gases, as well as various water-based, oil-based, and foam well-killing fluids. In order to ensure the safety and reliability of operations in such complex environments, flexible connecting pipelines came into being and play a vital role in practical applications.
1. Functions and applications of flexible connecting pipelines
Flexible connecting pipelines, as a special pipeline system, are mainly used to connect key equipment such as throttling and well-killing manifolds to achieve stable transportation of oil and gas mixtures and various well-killing fluids. Its unique structural design enables it to maintain good elasticity and sealing in harsh environments such as high pressure, high temperature, and corrosion, effectively preventing leakage and fracture accidents.
In the process of oil and gas extraction, hydrogen sulfide (H₂S) is a common and extremely dangerous gas. It is not only highly corrosive and toxic, but also prone to explosion accidents. Therefore, when transporting oil and gas mixtures containing hydrogen sulfide, extremely high requirements are placed on the material selection, manufacturing process and connection method of flexible connecting pipelines.
2. Material selection of flexible connecting pipelines
For oil and gas mixtures containing dangerous gases such as hydrogen sulfide, the material selection of flexible connecting pipelines is crucial. Generally speaking, these pipelines need to use special alloy materials that are corrosion-resistant, high-temperature-resistant and high-pressure-resistant, such as stainless steel, nickel-based alloys, etc. These materials have good mechanical properties and chemical stability and can maintain a long service life in harsh environments.
In addition, in order to improve the sealing and corrosion resistance of flexible connecting pipelines, a special anti-corrosion coating needs to be applied to the inside of the pipeline. This coating can effectively isolate the contact between the oil and gas mixture and the inner wall of the pipeline, reducing the risk of corrosion and leakage.
3. Manufacturing process of flexible connecting pipelines
The manufacturing process of flexible connecting pipelines is equally important. Generally speaking, the manufacturing process of these pipelines includes multiple links such as material preparation, molding, welding, heat treatment, and coating. In each link, process parameters and quality standards need to be strictly controlled to ensure that the quality and performance of the pipeline meet the requirements.
For example, in the welding process, advanced welding technology and equipment are needed to ensure the quality and sealing of the weld. In the heat treatment process, the heating temperature and insulation time need to be precisely controlled to eliminate the residual stress inside the material and improve the mechanical properties of the material. In the coating process, it is necessary to select suitable coating materials and coating processes to ensure the uniformity and adhesion of the coating.

4. Connection method of flexible connecting pipelines
The connection method of flexible connecting pipelines is also an important factor affecting their performance and safety. Common connection methods include flange connection, clamp connection, threaded connection, etc. When choosing a connection method, it is necessary to make a comprehensive consideration based on the specific working conditions and pipeline specifications.
For example, in harsh environments such as high pressure, high temperature, and corrosion, flange connection and clamp connection have better sealing and reliability. In some special cases, such as when quick disassembly or installation is required, threaded connection is more convenient and practical.
5. Maintenance and maintenance of flexible connecting pipelines
In order to ensure the long-term and stable operation of flexible connecting pipelines, regular maintenance and maintenance are also required. This includes checking the sealing of the pipeline, the integrity of the coating, the tightness of the connector, etc. When problems are found, they need to be handled and repaired in time to avoid accidents.
In addition, the pipeline needs to be cleaned and rust-proofed regularly to remove dirt and rust inside the pipeline. This can not only improve the transportation efficiency of the pipeline, but also extend the service life of the pipeline.
In short, flexible connecting pipelines play an irreplaceable role in the oil and gas industry. By selecting appropriate materials, manufacturing processes and connection methods, as well as regular maintenance and care, these pipelines can be ensured to maintain good performance and safety in harsh environments such as high pressure, high temperature, and corrosion. Thereby providing stable and reliable protection for oil and gas extraction.
