PE plastic pipe production line of plastic pipe materials used mainly PVC and PP, the high density polyethylene (HDPE) pipe has low density, good toughness, low friction coefficient, corrosion resistance, low temperature resistance, good insulation properties, easy construction and installation, the current market and development potential. China's current plastic pipe production capacity of 3 million 500 thousand tonnes / year, of which PE plastic pipe production capacity of 1 million 600 thousand tonnes / year.

Because the HDPE pipe performance / price ratio in other plastic pipe, so the expected future development in Chinese considerable market potential, prediction of the main potential markets:

1, drainage, sewage pipe

Although the Chinese mainland PE buried drainage pipe and sewage pipe use has just started, but with the country's attention to environmental protection, the market potential of this area is very large. At present, this area is about 80 thousand metric tons of HDPE pipes.

2, gas pipe

Huicong net plastic inquiry: at present, Chinese HDPE gas pipe demand only about 70 thousand tons / year, gas pipe accounted for only 14% of the market, far less than 90% of the United States, Europe 60%-70%, and is used for gas pipe HDPE basically rely on imports. Expected in the future with the improvement of gas pipe application technology and people's understanding of the superiority of HDPE gas pipe, HDPE gas pipe market potential.

3、夾芯管

HDPE包覆管具有保溫、使用壽命長(zhǎng)、防腐、易施工、可節(jié)能降耗等優(yōu)點(diǎn)，廣泛應(yīng)用于供熱、制冷和防腐等領(lǐng)域。2005年中國(guó)大陸在此領(lǐng)域需求量約為5萬(wàn)公噸，預(yù)計(jì)未來(lái)成長(zhǎng)率將在10%以上。

4、室內(nèi)外給水管

目前中國(guó)大陸城鎮(zhèn)的供水、海水淡化等工程越來(lái)越多采用HDPE管材。2004年HDPE給水管材需求量為15萬(wàn)公噸左右，預(yù)期未來(lái)隨著中國(guó)大陸自來(lái)水普及率的提高和城市建設(shè)，對(duì)HDPE給水管材的需求量將會(huì)越來(lái)越大。
