Seamless carbon steel pipe for well casing, high-precision seamless carbon steel gas pipe

Seamless carbon steel pipe for well casing, high-precision seamless carbon steel gas pipe

A geological casing pipe is a specialized pipe used in geological drilling and tunnel support. Its primary functions are to protect wellbore walls, provide isolation and guide the drill string, prevent wellbore collapse, isolate different geological formations, and serve as a conduit for drilling operations. These pipes are typically manufactured from steel grades such as DZ40, DZ50, DZ60, and the R780 series, and comply with national standards like GB/T 14975-2012. Depending on their application, geological casing pipes are classified into drill pipes, drill collars, casing pipes, and other categories; they are suitable for oil well drilling, tunnel reinforcement, and various other uses. A wide range of sizes and price points are available, including thick-walled API 5CT N80 L80 oil casing pipes, seamless K55/J55 oil casing pipes, and more.

Steel pipe pile structures are foundation piles composed of steel pipes with pointed tips. They are bent into arc-shaped configurations and used in projects such as waterbody and soil retaining structures. These piles feature a simple design, excellent watertightness, and high strength. Their outer diameter typically ranges from 50 to 120 cm, with wall thicknesses from 1 to 18 cm, and they are most commonly fabricated from low-alloy steels of grades Q235 or 16Mn. Steel pipe piles are widely employed in the construction of bridges, piers, subway systems, and other infrastructure, particularly in areas with soft soils, where they effectively distribute loads and prevent settlement.

Pile structures made of steel pipes are construction piles consisting of steel pipes with pointed tips. They are assembled into arc-shaped configurations and are used in projects such as barriers for water bodies and underground spaces. These piles feature a simple design, excellent watertightness, and high strength. Their outer diameter typically ranges from 50 to 120 cm, with wall thicknesses from 1 to 18 cm, and they are most commonly fabricated from low-alloy steels of grades Q235 or 16Mn. Steel tubular piles are widely employed in bridge construction, dock facilities, subway systems, and other projects—particularly in areas with soft ground—to effectively distribute loads and prevent settlement.

A steel grouting pipe is a cementing pipe with regular, small holes drilled through the wall of standard steel pipes. Soil or rock reinforcement is achieved by injecting grout. It is widely used in tunnel construction, slope stabilization, and other projects. Standard diameters range from 42 to 108 mm, with typical lengths of 6 or 12 meters; custom configurations are also available.

Degassing pipe

Gas drainage pipes are specialized pipelines used in coal mines to extract gas from coal seams, surrounding rock formations, and mined-out areas. They convey combustible gas to the surface or to safe zones by creating a vacuum, thereby preventing gas accumulation and explosions. Their primary purpose is to ensure mine safety; at the same time, the extracted gas can be utilized as a resource—for example, for power generation or for domestic gas supply.
