Cost Analysis of Large Diameter Structure Wall Pipe

In China, the development of large-diameter structural wall pipes for buried drainage originated in the mid-1990s. Prior to this, large-diameter plastic pipes for buried drainage were mainly PVC-U solid wall pipes. Since the production equipment for large-diameter structural wall pipes is expensive, there are few enterprises that can invest in the production of large-caliber structure wall pipes. Many enterprises that originally produced PVC-U solid wall buried pipes have difficulty in upgrading pipes.

Shanghai Tomson Plastic Industry Co., Ltd. organized the company's technical strength, consulted relevant foreign technical information, used the original equipment for producing PVC-U solid wall buried pipes, purchased the necessary pipe extrusion molds and auxiliary equipment, and used the minimum equipment investment. Self-developed and developed PVC-U porous pipe for buried drainage, increased the pipe type of large-diameter structural wall pipe for buried drainage, filled the domestic gap, the product has passed the technical appraisal organized by the Shanghai Economic Commission, and applied for a patent . The cross-sectional structure of PVC-U porous pipes for buried drainage is different from other structural wall pipes. PVC-U porous pipes are characterized by axially distributed structural pore walls. Since the pipe is sealed and connected by a socket rubber ring, in order to prevent the leakage of the axially distributed hole wall, the socket end face of the pipe must be sealed.

Physical and mechanical properties of PVC-U porous pipes for buried drainage. Physical and mechanical properties of pipes, physical and mechanical properties of pipes. Index testing methods. Ring stiffness. Features of PVC-U porous pipe for buried drainage: the overall strength of the pipe is balanced, there is no weak point, the inner and outer walls of the pipe are smooth, the appearance and construction are the same as the solid wall pipe, the installation and construction are convenient, the pipe has a double-layer pipe wall, and reliability Good, the ring has high stiffness, the pipe wall is thin, the inner diameter of the pipe is relatively large, and the water passing capacity is large.
