Pipe Selection Guide for Petroleum Industry: Comprehensive Analysis from Specifications to Materials

In the petroleum industry, pipelines are used everywhere, from drilling to gathering, to transportation and processing, in which all kinds of pipes play a vital role. Among them, pipe specifications, assemblies, braided hoses, braided pipes and oil drilling hoses are some common pipe types in the petroleum industry. This article will detail the characteristics, applications and how to properly select and use these pipes to optimize operating efficiency and safety in the petroleum industry.

1. Oil pipe specifications and types

Oil pipes can be divided into drill pipes, casing and tubing according to their functions. The drill pipe is mainly used to connect the drilling rig and the drill bit, transmit torque, and perform drilling operations; the casing is used to protect the drilling hole wall and prevent the collapse of the oil well; the oil pipe is used to export oil or natural gas from the underground. The specifications of each pipe include information such as diameter, wall thickness, length and material, which are factors that must be carefully considered when selecting pipe materials. For example, large-diameter pipes are often used in main pipelines, while small-diameter pipes are more suitable for detailed connections or the transportation of smaller flows.

Standards such as API (American Petroleum Institute) standards provide a series of guidance on specification selection, including API 5D standards for drill pipes and API 5CT standards for tubing and casing.

2. Assembly pipes and their importance

In petroleum pipeline systems, an assembly refers to a composite component composed of a variety of pipeline components. These assemblies are usually pre-assembled in the factory according to strict specifications, and only require simple connection and installation on site, which greatly improves the installation efficiency and system reliability. For example, an assembly may be a pipe section including valves, measuring devices, and regulating devices used to control and monitor oil flow.

3. Braided hose and braided tube

Braided hose and braided pipe are widely used in the petroleum industry due to their excellent pressure resistance and flexibility. They usually consist of an inner rubber layer, a reinforcement layer (such as wire braid), and an outer rubber layer. The inner rubber layer is in direct contact with the transported medium and must have certain chemical stability and oil resistance; the reinforcement layer is responsible for providing sufficient mechanical strength; the outer rubber layer protects the pipe from erosion by the external environment. This type of pipe is particularly suitable for high pressure and dynamic applications in harsh environments, such as hydraulic systems on offshore drilling platforms.

4. Application of oil drilling hose

Oil drilling hoses are pipes designed to connect moving parts of drilling equipment and require extreme flexibility and high pressure resistance. The pipe is able to withstand the high pressures generated by pumped drilling mud, while also needing to resist corrosion from oil, natural gas and other chemicals. In addition, considering that drilling operations are often carried out in changing environments, this type of hose also needs to have good resistance to climate change to ensure stable performance under extreme temperature and pressure changes.

5. Correct selection and maintenance of pipe materials

Choosing the right oil pipe material requires not only considering its physical and chemical properties, but also the specific needs in the application scenario, such as temperature, pressure, flow rate and medium type. For example, in highly corrosive environments, pipes made of corrosion-resistant materials, such as stainless steel or special alloys, should be selected. At the same time, regular pipeline inspection and maintenance are also indispensable to ensure the safe operation of the oil pipeline system. This includes cleaning and inspecting pipes, detecting leaks and replacing worn parts.


The pipeline system of the petroleum industry is its lifeline. Determining the appropriate pipe specifications and types, as well as correct installation and maintenance, are crucial to ensuring the safe and efficient operation of the petroleum industry. As mentioned in this article, each pipe material has its specific application scenarios and selection criteria. The correct understanding and use of these pipe materials will directly affect the success of the oil project.
