Description

Technical Field

[0001] This utility model relates to the field of nylon pipe technology, and in particular to a steel-lined detachable nylon pipe. Background Technology

[0002] Nylon pipes, as a type of high-performance engineering plastic pipe, are widely used in slurry material conveying systems in industries such as mining, power, and dredging due to their excellent wear resistance, corrosion resistance, smooth surface, and light weight. These pipes typically have large diameters (50-120 cm) and are used frequently under harsh operating conditions. To protect nylon pipes from external mechanical impacts, improve their pressure resistance, and facilitate connection with other metal components in the system, the industry commonly uses a composite structure with an external steel bushing (steel liner). This structure fully utilizes the wear and corrosion resistance of the nylon liner and the high strength of the external steel. However, most of these composite pipes currently employ a "fixed" or "encased" steel liner structure, meaning the steel liner is permanently or semi-permanently fixed to the outer wall of the nylon pipe through interference fits, welding, or numerous bolts.

[0003] The prior art patent document CN217482222U provides a steel-lined detachable nylon pipe, relating to the field of nylon pipe technology. It includes a pipe body with a first steel liner on its outer side. A second steel liner is rotatably connected to the first steel liner via a hinge. Both the first and second steel liners have a circular hole at their center, and a fixing mechanism is installed through each hole. The fixing mechanism includes a T-shaped tube penetrating the inner wall of the circular hole. In this invention, the pipe body and the first and second steel liners are detachable and detachable. The first and second steel liners are connected by a hinge, the opening angle of which facilitates installation and disassembly. Finally, fixing bolts are used to connect the fixing ears at the bottom of the first and second steel liners, facilitating their installation and disassembly. An anti-slip arc plate serves to fix the first and second steel liners to the pipe body.

[0004] Although the device has many beneficial effects, the following problems still exist: after the slurry is transported, the inside of the steel-lined pipe will inevitably have residues, which need to be thoroughly cleaned regularly to ensure smooth flow and hygiene. If the pipe needs to be cleaned or replaced, the outer steel lining needs to be removed, which reduces the maintainability of the system.

[0005] Secondly, when it is necessary to inspect or replace the internal nylon pipes, the steel lining needs to be separated, and the flanges are too cumbersome to fasten and disassemble by fixing bolts, which greatly increases the cost and time of disassembly and installation.
