  Seamless Steel Pipe Manufacturing Process

  Seamless steel pipes are specially designed for transportation pipeline systems in high-pressure, high-temperature, and corrosive environments in the oil and gas industry. This kind of steel pipe is usually made of carbon steel or alloy steel with high strength and good corrosion resistance. Their production process includes advanced hot or cold rolling processes to ensure that the inner and outer surfaces of the pipes are smooth and defect-free.

  Three forming methods of LSAW steel pipe

  LSAW steel pipe is a pipe product made from a single medium-thick steel plate as raw material, which is pressed (curled) by a mold or forming machine to form a pipe blank, and then double-sided submerged arc welding is used to expand the pipe diameter in the process. Its product specifications range widely, with excellent weld toughness, plasticity, uniformity and density, as well as large pipe diameter, thick pipe wall, high pressure resistance, low temperature resistance and corrosion resistance. LSAW steel pipes have important application value in the construction of high-strength, high-toughness, and high-quality long-distance oil and gas pipelines.

  Load analysis and strength design of casing pipe

  As oil field exploration continues to expand and drilling depths gradually increase, the number of deep and ultra-deep wells is also increasing. As the depth of the well casing increases, the stress and deformation experienced by the well casing become more complex.

  Effective Ways to Stop Cement Slurry Leaks in Screen Casings for Oil Wells

  In recent years, with the continuous development of horizontal well technology and the expansion of its application scale, it has become one of the important means for efficient development of oil fields. The advantage of horizontal wells is that they can reduce the resistance to the flow of crude oil from the formation to the wellbore, thereby improving oil recovery efficiency. Usually, open-hole screen casing is used for sand control in the oil layer, and cement injection on the top of the screen above the deflection section is used to complete the well. These processes are designed to ensure the stability of the wellbore and the effective collection of crude oil.

  Key Features of Slotted Casing

  Grooved casing is a pipe component made using a special cutting method on petroleum or oil pipes. The production process usually involves cutting longitudinal or spiral straight or staggered slits of a certain specification, using special ultra-thin cutting blades and beam cutting technology to make the slit width of the slotted sleeve between 0.2 and 0.5 mm.

  Analysis of the advantages and disadvantages of different types of flanges

  Flange is a mechanical connection device, usually consisting of two circular metal plates, which are tightly connected together by bolts. Flange is called flange plate or flange by a few people. It refers to the connecting parts that are connected by bolts on two planes at the periphery, that is, the parts that connect the shafts to each other. It is also an important connection method in pipeline construction.
