China's plastic pipe development
2018-02-08 11:27:23

Plastic pipe has the characteristics of light weight, corrosion resistance, small water loss, easy installation and so on. It has been favored by plumbing engineering industry. At the same time, plastic pipe has less energy consumption (less than 1: 4 in general) compared with traditional metal pipe. Environmental pollution is small, and is increasingly valued by the government and relevant departments.

Abroad, plastic pipe is continuously replacing metal or other traditional materials, pipe, the rapid development. From the 1980-1990 years, except for plastic pipe, all kinds of other materials, the total pipe growth rate of less than 2%, but the growth rate of plastic pipe is 4 times the sum of the growth rate of other pipe, reaching 8% Demand for plastic pipe into the nineties is still growing at a rate of 4.2% per annum, with output increasing at an annual rate of about 8%.

Since the seventies of our country began to produce plastic pipe, the early eighties began to promote the construction of the project. In the past 20 years, the plastic pipe has been greatly developed, not only in terms of quantity, but also in variety and specifications have been greatly developed. By the end of 1999, there were about 2,000 plastic pipe production lines nationwide, of which 15% were imported equipment. In 1999, the production capacity of various plastic pipes in our country reached 1.65 million tons and the actual output was about 1 million tons. Among them, PVC-U pipe 500,000 tons, accounting for 50%; PE pipe 360,000 tons, accounting for 36%. In recent years, with the rapid development of the construction industry as an important pillar industry and residential industry in the national economy, plastic pipe for indoor construction has developed rapidly and has now become a hot spot for investment.

 The development of plastic pipe, the current main UPVC pipe and PE pipe-based, and to develop new composite, modified plastic pipe. In 2010, the main plastic pipe products to meet market requirements, the market complete products, quality, grade and supporting levels have significantly improved, the overall level close to the international advanced level. 80% of the construction drainage pipe adopts plastic pipe; 80% of the building water supply, hot water supply and heating pipe adopt plastic pipe; 90% of the wire protection pipe adopts plastic pipe; 70% The use of plastic pipe; urban water supply pipe (DN400Inm the following) 70% of the plastic pipe, 70% of the town water supply pipe with plastic pipe; 50% of urban drainage pipe with plastic pipe; city gas pipeline (medium and low pressure pipe) 60% of the plastic pipe.Food Hoses
