Technical Field
[0001] This utility model relates to the technical field of MPVC-T pipe structure, and in particular to a high-strength corrosion-resistant MPVC-T pipe. Background Technology
[0002] PVC pipes can be classified into various types based on their composition and manufacturing process, such as PVC-U, PVC-C, and PVC-O. PVC pipe, short for polyvinyl chloride pipe, is a plastic pipe material made from thermoplastic resin polymerized from vinyl chloride monomer. In the construction field, PVC pipes are mainly used for the protection of electrical wires and cables, the construction of drainage systems, and water pipe systems for interior decoration. In agriculture, PVC pipes are mainly used for irrigation system construction. In industry, PVC pipes are mainly used for transporting fluids and gases, and as pipelines for chemical equipment. In municipal engineering, PVC pipes are mainly used for urban drainage, water supply, and road construction. In environmental protection, PVC pipes are mainly used for sewage treatment and rainwater harvesting systems. PVC-M is a modified polyvinyl chloride pipe with better seismic performance, suitable for applications requiring higher strength and durability. MPVC-T pipes have wide applications in the power and communication fields, and can be used to protect cables, wires, and other line facilities, improving the safety and stability of the lines. Furthermore, its excellent physical and chemical properties allow it to maintain good performance even in various harsh environments.
[0003] MPVC-T pipes are made of rigid polyvinyl chloride and have good physical and chemical properties, such as corrosion resistance, wear resistance, and high strength. They are named MPVC-T pipes because their shape resembles the letter "T". In the current technology, MPVC-T pipes usually use a flared socket connection method. This method has several problems: First, the T-shaped pipe usually has three openings, and the position and tilt angle of the spliced pipe openings cannot be adjusted. The pipe must be aligned with the three openings of the T-shaped pipe. Second, there is no sealing structure between the pipe and the inner wall of the T-shaped pipe openings, and the pipe is not easy to insert into the T-shaped pipe, requiring frequent adjustments for alignment.
