  Piling Pipe Size

  Piling pipe is a building material composed of ERW steel pipe or SSAW steel pipe, which is widely used in various engineering projects. Piling pipe comes in a variety of sizes and can support loads from 50 to 500 kilopounds. The diameter ranges from a few inches to a few feet, and the common size ranges from 8 inches in diameter to more than 50 inches in diameter. If you want to buy used piling pipe, the most choices are in the diameter range of 18 inches to 28 inches. Piling pipes can be connected together to form pile structures hundreds of feet long. In offshore and inland alluvial plain areas, the 50 to 60-meter thick soft soil layer under the upper load cannot be directly used as the bearing layer. The low compressive bearing layer is often deeper, and the piling pipe structure is usually used because the pile hammer exerts a greater impact force on it. At this time, it is more appropriate to use piling pipe to strengthen the foundation than to use conventional reinforced concrete piles and prestressed concrete piles.

  What is Seamless Carbon Steel Pipe?

  Seamless carbon steel pipe is a rough tube made by perforating a steel ingot or solid tube billet. It is a seamless tube, and then a steel pipe made by hot rolling, cold rolling or cold drawing. This kind of steel pipe is widely used in construction, petroleum, chemical industry, machinery and other fields due to its seamless characteristics, high strength, good corrosion resistance and good weldability. This kind of steel pipe is not only used for pipeline transportation, but also widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding in construction. Although there are many types of seamless carbon steel pipes, they all have some common key characteristics, such as strength, hardness and durability. This article will introduce the manufacturing process, classification, application fields and characteristics of seamless carbon steel pipes in detail.

  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.

  Application of rectangular tubes in automobile chassis

  Rectangular tubes are a kind of hollow long steel strips, also known as flat tubes, flat square tubes or square flat tubes (as the name implies). Like square tubes, they are widely used as pipes for conveying fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strengths are the same, the weight is lighter, so they are also widely used in the manufacture of mechanical parts and engineering structures. They are also commonly used in the production of various conventional weapons, gun barrels, shells, etc. The application of rectangular tubes in automobile chassis is also very common. The following will introduce the process of using rectangular tubes in automobile chassis.
