Application of oil casing in ship construction and its material requirements

In the field of ship construction, oil casing is a vital component. They are widely used in oil and gas extraction, transmission and storage process, play a key role. This paper will discuss the application of oil casing in ship construction and its requirements for materials.

Oil casing is a piping system used to transport oil and gas from a wellhead to storage and processing facilities. In ship construction, oil casing is mainly used to build oil tankers and other offshore oil transportation equipment. They undertake the task of transporting oil from offshore wellheads to land, but also need to ensure the safety and reliability of the transmission process.

The material requirements of oil casing are very high. First, they need to be resistant to corrosion, because the casing can be exposed to harsh environments for long periods of time under the action of seawater and oil. Therefore, common material choices include high-strength stainless steel and corrosion-resistant alloy steel.

Secondly, the oil casing needs to have high strength and pressure resistance. During sea transportation, the casing needs to withstand huge pressure, so materials with good strength and pressure resistance must be selected. These materials often require rigorous testing and certification to ensure their reliability and safety.

In addition, the sealing of the oil casing is also very important. Casing is required to ensure that oil and gas do not leak or seep during long periods of maritime transport. Therefore, both the material selection and the casing connection method need to have good sealing performance to prevent any leakage accident.

To sum up, the application of oil casing in ship construction is very extensive, and the requirements for materials are very strict. Corrosion resistance, high strength, pressure resistance and good sealing performance are the main requirements of oil casing. Only by selecting suitable materials and adopting suitable processes and methods can the reliability and safety of oil casings be ensured during marine transportation.
