Tubing is mainly used to provide oil and gas flow passage during production of oil and gas wells. For flowing wells, due to the large inner diameter of the CASING, the casing is directly used for production. Due to the density difference, pressure drop and expansion, the liquid flows up rapidly, causing the liquid to slip, resulting in the ineffective utilization of the downhole elastic energy. Running tubing with smaller OD and ID during production can effectively solve the above problems by allowing fluid to flow in the tubing. Therefore, running tubing is required during production of flowing wells. The downhole operation and production of flowing well and non flowing well can be completed by using various tools for tubing running.
The basic requirements of the tubing used for workover are: to comply with the safety and economic principles, to meet the technical requirements adopted during well completion, and to meet the requirements for corrosion resistance and operation measures after the well is put into production.
According to the manufacturing process, oil pipes can be divided into seamless pipes and electric welded pipes. Seamless pipe is a kind of forged steel pipe without welding seam, which is made of hot working steel. After pressing, stretching, heat treatment and other processes, it reaches the standard size of oil pipe, forming a seamless oil pipe series. Electric welding pipe is a kind of pipe with a longitudinal weld formed by resistance welding or electric induction welding without filler metal. The welding edges are squeezed together by mechanical pressure, and the standard size oil pipes are reached through heat treatment and other processes, forming a series of electric welding pipes.

Recently, Bridgestone has brought its latest cutting-edge scientific and technological achievements, as well as main products covering passenger cars, trucks, trucks, and even aircraft tires, to participate in this year's Guangzhou Auto Show, demonstrating that companies can explore sustainable industrial changes. The innovative spirit of the road to development.
Bridgestone takes the theme of “Green Living, Seeing the Future†at this year's Guangzhou Auto Show. Through the three areas of “Reduce Carbon Emissions,†“Treasure Resources,†and “Safety and Controlâ€, Bridgestone has demonstrated the diversified development of enterprises. Track. One of the most sought-after new tyre technologies that deserves the attention of Bridgestone – equipped with a “large-diameter, narrow-tread†concept tire with a combination of energy-saving, fuel-efficient and safe driving, has already been put into practical use. And officially opened the new name "ologic". Another representative technology of Bridgestone's latest tire innovation concept - "non-pneumatic tires" that breaks the traditional tire concept, as well as RFT tires equipped with run-flat technology, and Bendak Tire retread technology have appeared. Together with passenger tires, truck tires, bus tires, aircraft tires, and even the world's largest class of construction tires, it demonstrates Bridgestone's strong corporate strength.
