Alloy pipe is a type of steel pipe in which alloying elements such as chromium, molybdenum, and nickel are added to carbon steel. It exhibits higher strength, superior corrosion resistance, and enhanced resistance to high temperatures. Alloy pipes are widely used in the petroleum, chemical, power, aerospace, and automotive industries, among others, particularly in applications involving high temperatures and high pressures.

A seamless pipe is a metal pipe without weld seams, typically manufactured from steel billets or solid tube blanks by piercing, hot rolling, or cold drawing. It boasts high strength, excellent corrosion resistance, and superior pressure resistance, making it widely used in the oil, chemical, and mechanical engineering industries, as well as other sectors.

A geological casing pipe is a specialized pipe used in geological drilling and tunnel support. Its primary functions are to protect borehole walls, provide isolation and guide the drill bit, prevent wall collapse, isolate different strata, and serve as a conduit for drilling operations. The materials used in its manufacture include steel grades such as DZ40, DZ50, DZ60, and the R780 series, and it complies with national standards like GB/T 14975-2012. Depending on their application, geological casing pipes are classified into drill pipes, drill strings, casing pipes, and other categories; they are suitable for oil well drilling, tunnel support, and various other applications. 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.

Alloy pipe is widely used in the oil and gas industry, chemical industry, power generation, aerospace, automotive manufacturing, and other sectors, particularly under conditions of high temperature and high pressure.

Self-drilling hollow injection anchor

Self-drilling hollow injection anchor

A hollow anchor is a support element that, thanks to its hollow design, serves both cementing and reinforcing functions. It is widely used in tunneling, mining operations, slope stabilization, and underground structures. The main material of the anchor’s shank is seamless steel pipe of grade Q345, which comprises a hollow shank, a bearing plate, a nut, and other components, and also functions as a grouting pipe. The hollow construction enhances shear resistance, the threaded configuration increases anchoring strength, and the grouting process consolidates fractured rock mass and improves the condition of the surrounding rock. During construction, there is no need to install a separate grouting pipe, thereby simplifying the construction process and increasing its efficiency.

A hollow anchor is a support element that, thanks to its hollow design, provides cementation-based reinforcement. It is widely used in tunneling, mining operations, slope stabilization, and underground construction. The body of the anchor is typically made from seamless Q345 steel pipe; it consists of a hollow rod, a bearing plate, a nut, and other components, and also functions as a grouting conduit. The hollow structure enhances shear resistance, the threaded configuration increases anchoring strength, and the grouting process consolidates fractured rock mass and improves the condition of the surrounding rock. During construction, there is no need to install a separate grouting pipe, which simplifies the construction process and increases its efficiency.

The longitudinal-slotted anchor system is a fully anchored support element that reinforces the surrounding rock mass through friction and radial pressure between the longitudinally slotted steel pipe and the borehole wall. It is suitable for mining operations, tunnel construction, and other projects.
