Steel casing pipe is a pipe installed in a drilling wellbore. Its primary function is to support the wellbore wall, prevent collapse, protect fluid channels, and extend the service life of the entire system.
Common steel casing pipe materials include galvanized steel pipe, welded steel pipe, and seamless steel pipe. Depending on the specific working conditions, these materials offer advantages in strength, sealing, corrosion resistance, and maintainability:
Welded casing pipe offers advantages such as high strength and good sealing, but is difficult to disassemble. This type of steel casing pipe is generally used in projects such as connecting the same natural gas pipeline.
Seamless casing pipe has a smooth surface, uniform inner and outer walls, and is resistant to rust. It is generally used for connecting tap water and natural gas pipelines.
Galvanized casing pipe offers excellent rust resistance and is suitable for applications such as outdoor drainage, wall penetration protection, and communication cable protection.

Note:
The above data is a partial list of common weights. Actual specifications depend on wall thickness and material grade.
To quickly estimate steel casing pipe weight during selection or quotation, use the steel casing pipe weight calculation formula.
Heavier steel casing pipe generally has thicker walls, resulting in greater resistance to compression, bending, and deformation, effectively preventing wellbore collapse.
Heavier steel casing pipe is more difficult to hoist, transport, and lower into the wellbore, placing higher demands on equipment.
Lightweight steel casing pipe is easier to install and more efficient, making it suitable for shallow wells or temporary projects.
Heavy steel casing pipe uses more steel, resulting in higher material and transportation costs.
Lightweight steel casing pipe is less expensive and suitable for projects with limited budgets.
Heavier steel casing pipe has thicker walls, better corrosion and wear resistance, longer service life, and tighter seals at joints, preventing leaks.
Steel casing pipe is an indispensable component in drilling and pipeline engineering. Its weight determines its strength, construction difficulty, cost, and applicable scenarios. Understanding the weight table for steel casing pipe not only helps engineers accurately select the right type during the design phase but also effectively manage costs and risks during construction. When selecting a type, comprehensive considerations should be made based on the project's pressure level, well depth, environmental conditions, and budget to achieve the optimal balance between safety and cost effectiveness.
