Plastic coating for pipelines and pipework
The plastic coating adheres tightly to the pipe surface, forming a robust protective barrier that effectively prevents contact between the pipe and external corrosive agents, thereby significantly extending the pipe’s service life.
Through thermal insulation, the medium within the pipeline experiences reduced heat loss during transportation. Whether it is hot water, steam, or a refrigerant, the fluid can maintain its set temperature for an extended period, thereby lowering energy consumption and helping enterprises significantly reduce operating costs.
As conduits for transporting critical media such as oil, natural gas, and water, pipelines’ safety and durability are directly linked to the stability of energy supplies and the reliable operation of public infrastructure.
Plastic-lined steel pipe is a steel–plastic composite pipe that uses a steel pipe as the base and features an inner lining of thermoplastic. The base pipe may be seamless steel, straight-seam welded steel, or hot‑dip galvanized steel. Through processes such as diameter‑reduction compounding, thermal expansion compounding, and rotomolding, the plastic liner is tightly bonded to the inner wall of the steel pipe. The outer steel layer provides mechanical pressure resistance and structural strength, while the inner plastic lining isolates the conveyed medium, delivering corrosion resistance and anti‑scaling performance. These pipes are widely used in domestic water supply and drainage, chemical fluid handling, environmental wastewater treatment, and process‑medium transport applications.
A reducer, also known as a reducing coupling, is a pipe fitting used to connect pipes of different diameters. It is broadly classified into two main types: concentric reducers and eccentric reducers.
A tee is a three‑port fitting used in piping systems to either divert flow or combine flows.
Elbows exhibit excellent fluid‑guiding performance, enabling smooth changes in the flow direction of the medium within a pipeline while reducing fluid resistance, thereby lowering energy consumption and enhancing system efficiency.
Flanges are universally applicable and interchangeable; whether in piping systems made of different materials or available in various sizes, or in a wide range of complex industrial equipment, their standardized design enables precise connections, significantly streamlining installation and maintenance.
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.
