Comprehensive economics of PE co-laminated siphon fittings

In terms of comprehensive economy, the advantages of plastic pipe are gradually recognised by the majority of users. The unit price of plastic pipe is slightly higher than cement pipe, but the total cost of the project is not higher than cement pipe. Tianjin Municipal Engineering Design Institute from 1992 on UPVC double-wall corrugated pipe, Jiaxing PE co-layered siphon fittings company from 1998 on PE two-wall corrugated pipe in the application of buried drainage pipe for systematic research. Conclusion: "The engineering cost of double-wall corrugated pipeline is comparable to that of concrete plain pipe and 30% lower than that of socket concrete pipe. The construction cycle is significantly shortened and the economic benefits are remarkable.

Large-calibre outdoor PE landfill pipe is the world's development trend in the past 10 years, Taizhou PE cohesive siphon pipe fittings company in the international plastic pipe a clear development trend is the water supply and gas transmission PE pipe development rate is very fast. Since 1998, the Munich International Coal Federation LGU gas distribution committee unanimously recommended PE landfill gas pipeline as a distribution pipe, after more than a decade of research and development in all countries of the world, PE pipeline has developed into a multi-species, and developed into a number of applications pipe.

From the point of view of gas distribution, PE pipeline has entered the urban water supply and drainage, Wenzhou PE homogeneous siphon pipe fittings company farmland irrigation, emissions, mining and oil fields, floor heating, chemical medicine and other fields. Statistics show that PE pipes are rising at a rate of 10-15 per cent per year.
