Sleeve valve pipe is a special pipe used in grouting projects. It is widely used in chemical industry, construction, petroleum, fire protection, electric power and other fields. It is made of various materials, including carbon steel, cast iron, stainless steel and other metal materials. The specific choice depends on the use environment and pressure requirements. Sleeve valve tubes are usually designed with flange interfaces or threaded interfaces for easy installation and connection, ensuring tightness and stability. In a high-pressure environment, the safety valve design of the sleeve valve pipe is particularly important, which can effectively regulate the pressure and prevent the pipe from bursting.
Geological casing is a special pipe used for geological drilling and tunnel support. It mainly plays the role of wall protection, isolation and guidance, prevents hole wall collapse, isolates different strata, and serves as a drilling channel. Its materials include DZ40, DZ50, DZ60 and R780 series steel grades, and comply with national standards such as GB/T 14975-2012. It can be divided into drill pipes, drill collars, casing and other categories according to their uses, and is suitable for oil well drilling, tunnel support and other scenarios. There are various specifications and prices of geological casing to choose from, such as API5CTN80 L80 thick-walled oil casing, K55/J55 seamless oil casing, etc.

The acoustic detection tube is a metal pipe embedded inside the concrete cast-in-place pile. It serves as a channel for the ultrasonic detection probe and is used to detect the integrity, defect location and uniformity of the concrete on the pile body. Its outer diameter is usually 50-60mm, wall thickness is 0.8-3.5mm, the length can be customized, and the connection methods include clamping type, screw type, etc. Depending on the pile diameter, 2-4 piles need to be buried in a symmetrical or equilateral triangle arrangement. The acoustic tube is a "stethoscope" for pile foundation quality testing and is widely used in bridges, construction, water conservancy and other engineering fields.
Seamless Carbon Steel Pipe
Seamless pipe is a metal pipe without welds, usually made of steel ingots or solid tube blanks through perforation, hot rolling or cold drawing. It has high strength, corrosion resistance and high pressure resistance, and is widely used in petroleum, chemical industry, machinery manufacturing and other fields.
Alloy Tube
Alloy pipe is a kind of steel pipe with added alloy elements such as chromium, molybdenum and nickel on the basis of carbon steel. It has higher strength, corrosion resistance and high temperature resistance. It is widely used in petroleum, chemical industry, electric power, aerospace, automobile manufacturing and other fields, especially in high temperature and high pressure environments.
Self-Propelled Hollow Grouting Anchor
Hollow anchor is a support component that achieves grouting reinforcement function through hollow design. It is widely used in tunnels, mining, slope stabilization and underground engineering. The material of the rod body is mostly Q345 seamless steel pipe, which is composed of hollow rod body, backing plate, nut and other parts, and also has the function of grouting pipe. The hollow structure can improve the shear resistance, the thread design enhances the anchoring force, and the grouting process can consolidate the broken rock mass and improve the surrounding rock. There is no need to install a separate grouting pipe during construction, simplifying the process and improving efficiency.

Ordinary Hollow Grouting Anchor
Pipe Joint Anchor
The pipe-slit anchor is a full-length anchored support component that strengthens the surrounding rock through the friction and radial pressure between the longitudinally-slit steel pipe and the borehole wall. It is suitable for mining, tunnels and other projects.
Gas drainage pipes are special pipes used in coal mines to extract gas from coal seams, rock formations and goaf areas. They pump combustible gas to the ground or safe areas through negative pressure to prevent gas accumulation and explosions. Its core function is to ensure mine safety, and at the same time, the extracted gas can be utilized as resources (such as power generation, residential gas).
The steel flower pipe is a grouting pipe with regular small holes drilled into the wall of ordinary steel pipes. The soil or rock formation is reinforced by injecting slurry. It is widely used in tunnels, slope support and other projects. Its regular specifications are 42-108mm, and the length is usually 6 meters or 12 meters, which can be customized.
