Grouting pipes are primarily pipeline devices used to inject grout. Their core functions include sealing joints, reinforcing foundations, and preventing leakage; they can be pre-embedded prior to concrete placement or installed afterward.
“Small guide tubes” are advanced support elements in tunnel engineering—specifically, grouting small guide tubes or steel flower pipes—and serve as advance support systems in civil engineering. Their applications include pre‑support and ground reinforcement prior to tunnel excavation or foundation pit construction in weak, fractured strata.
It is widely used in various bridge and tunnel projects. Thanks to its distinctive mechanical properties and ease of construction, rock bolts have become an essential method for reinforcing soil and rock masses and enhancing structural stability.
As an advanced support technique widely employed in tunnels, underground engineering, and slope stabilization, the pipe canopy system can be custom-designed to suit varying geological conditions.
Clamp-type acoustic logging casing
The clamp-type acoustic testing tube, also known as the sonic testing tube, is a specialized device used for pile foundation testing. This pipe fitting features a double-ended, double-sealing design. At the socket end, a U-shaped groove is provided along with a rubber sealing ring; hydraulic pliers are then used to compress the fitting, forming a hexagonal connection that ensures a double-sealed, anti-loosening effect.
Clamp-type acoustic logging casing
Featuring weld-free installation and excellent resistance to pull-out and torque, the connection can be completed with a single crimping operation. It comes in three basic models: 50, 54, and 57. Its hexagonal crimping structure prevents loosening of the joint, and the installation process does not require specialized technicians, effectively saving time and reducing material waste.
Steel flower pipes are widely used in the pile foundation construction industry, where their quality is of paramount importance. The steel flower pipes offered in our store are made from Q235B strip steel and come in a variety of specifications, with diameters ranging from 20 to 108 mm.
