  What size is a casing pipe?

  There are certain differences between tubing and casing in terms of size, structure and purpose. The size of tubing is relatively small, and it is mainly used to transport oil and gas, while the size of casing pipe is relatively large, and it is mainly used to fix the wellbore and isolate the formation. However, some pipes with the same specifications can be used interchangeably. At the same time, tubing and casing pipe also have a certain connection during use. They are both important components of the well and must be coordinated and cooperated with each other. At the same time, they must also cooperate and support with other accessories to ensure the safety and stability of drilling and production. This article will introduce the basic concepts and size specifications of tubing and casing in detail, and I hope it will be helpful to you.

  Study on soil squeezing effect of piling pipe

  piling pipe include steel piling pipe and prestressed concrete piling pipe. These piling pipe are widely used in various construction projects and are favored for their advantages of saving materials, high bearing capacity, good penetration and low soil squeezing effect. However, as a semi-squeezing pile, the soil squeezing effect of open piling pipe still limits its application range. The length of the soil plug formed during the pile sinking process is usually 1/3 to 2/3 of the pile length, and the volume of soil discharge is still large.

  The difference between galvanized steel pipe and seamless steel pipe

  Steel pipes are divided into welded steel pipes and seamless steel pipes. As an important component of steel, steel pipes are divided into two categories: welded steel pipes (plates, strip billets) and seamless steel pipes (round billets) due to their different manufacturing processes and billet shapes. As for galvanized steel pipes and seamless steel pipes, it cannot be said that there is any difference in material. Their classification standards themselves are different. Galvanized pipes are a surface treatment process. As an important material in modern industry and construction, steel pipes have a wide range of types and applications. This article will explore in depth the differences, manufacturing processes, performance characteristics, and applications of seamless and galvanized steel pipes in different fields.

  How to deburr slotted casing?

  Slotted casing is one of the key equipment in oil drilling operations and is widely used in pre-completion and oil production sand control operations. Slotted casing is usually made of seamless steel pipe. Seamless steel pipe has high strength and corrosion resistance, and is suitable for manufacturing slotted casing for filtering and screening various materials. The performance and life of slotted casing directly affect the efficiency and safety of the entire oil production process. Slotted casing after drilling often produces burrs inside and outside the hole, which will affect the normal use of the slotted casing. Therefore, deburring is an important process in the manufacture of slotted casing. This article introduces the process of deburring the inside and outside of the slotted casing in detail for your reference.

  Rectangular Steel Tube Applications in Car Chassis

  Rectangular tubes have become a common structural material in many modern vehicle chassis systems. Compared with round or square tubes, rectangular tubes offer better bending stiffness in certain directions, making them suitable for side beams, cross-members, load-bearing frames and EV battery-pack structures. In many factories, they are often referred to simply as rect tubes or rectangular hollow sections (RHS).

  How is the casing pipe installed?

  Casing pipe is mainly composed of couplings and pipe bodies. In order to ensure the reliability of oil casing pipe in use and facilitate transportation, the separate pipe bodies and couplings are bolted together in the factory and then transported to the oil and gas field site. On site, the casing is connected end to end and used after the required length is reached with the pup joint. In order to enhance the compressive strength and tightening control of the bolted connection, electric welding is required after the coupling and pipe body are bolted together. Therefore, it is particularly important to analyze the electric welding characteristics of materials such as 37Mn5 and formulate a scientific and reasonable welding method.

  What are non-magnetic drill collars?

  Non-magnetic drill collars are low-magnetic tools specially used in oil drilling and other drilling projects. They are made of low-carbon high-manganese alloy steel. Through strict chemical composition ratio and refining process, and after forging treatment, non-magnetic drill collars have achieved excellent mechanical properties. Its unique properties include good low magnetic permeability, high-strength mechanical properties, excellent intergranular corrosion cracking resistance and excellent wear resistance.

  Application and development of large diameter seamless steel pipe

  Large-diameter seamless steel pipes (Ф4061500mm x 6.4270.0mm) are very common in modern industry and are widely used in general fluid delivery pipes, oil and gas pipelines, structural pipes, pressure vessel pipes, high-pressure boiler pipes and military pipes. The standard for large-diameter seamless steel pipes is ASTM A252. The materials of these steel pipes mainly include high-quality carbon structural steel, alloy structural steel, stainless steel and special alloys. Although China's small and medium-diameter seamless steel pipe production equipment has developed rapidly, the production of large-diameter seamless steel pipes is still lagging behind. At present, China has more than 150 seamless steel pipe production plants, with about 289 sets of various seamless steel pipe units (including 17 sets under construction), of which only about 11 sets of main equipment (including those under construction) can produce large-diameter seamless steel pipes. Despite this, it still cannot meet the market's growing demand for large-diameter seamless steel pipes.
