2. Petroleum Tubing: Specifications 1.05”-4-1/2” with End Processing Forms NU (Non-Upset) and EU (Upset) Petroleum tubing is one of the essential devices in the process of oil extraction and transportation. Its main function is to transport oil and natural gas from underground to the surface. At present, the common specifications of petroleum tubing on the market range from 1.05 inches to 4- 1/2 inches, which can meet the extraction requirements of different oil wells. There are mainly two types of end processing forms for tubing: NU (Non-Upset) and EU (Upset). The NU end processing form refers to no additional thickening treatment at the end of the tubing. The advantage of this processing form is the lower cost, which is suitable for some wells with lower strength requirements. The EU end processing form, on the other hand, involves thickening the end of the tubing, which can greatly increase the tensile and torsional strength of the tubing, enabling it to better adapt to high-pressure and complex downhole environments. Different specifications and end processing forms of tubing have their own characteristics in practical applications. For example, the small-diameter tubing of 1.05 inches is usually used in some small oil and gas wells. Its smaller diameter can reduce drilling costs, and in some areas with better geological conditions, this specification of tubing can also meet the extraction requirements. The large-diameter tubing of 4-1/2 inches is mainly used for the extraction of large oil wells and deep wells, which need to withstand greater pressure and flow. Therefore, the requirements for the strength and sealing of the tubing are higher. When selecting petroleum tubing, users need to make decisions based on the specific conditions of the oil well. For example, in some oil wells containing corrosive gases, tubing with anti- corrosion coatings should be selected; in high-pressure oil wells, tubing with the EU end processing form should be chosen. In addition, the material of the tubing is also very important. Common materials include carbon steel, alloy steel, etc., and there are differences in performance and cost for tubing made of different materials. The manufacturing process of petroleum tubing is also very strict and involves multiple procedures, including inspection of raw materials, formation of the tube body, end processing, and quality inspection. Each procedure must be carried out strictly in accordance with national and industry standards to ensure the quality and performance of the tubing. With the continuous progress of science and technology, the manufacturing technology of petroleum tubing is also constantly innovating. In the future, more high-performance and high- reliability tubing products will be introduced to the market, providing strong support for the sustainable development of the oil industry.
