A guaranteed high quality water supply is an essential element for good health and high quality life. High level of sulfate, chloride and nitrate ions in drinking water will cause pollution to the water and corrosion to the inside surface of the pipe. If a corroded pipe line is used to transfer drinking water it will inevitably cause sever health problem.

For PE-lined Galvanized Steel Pipe, it is a composite pipe with outer layer of hot dip galvanized welded steel pipe and inside layer of HDPE pipe bonded together under high temperature and pressure. Therefore, It is not only with the advantage of high mechanical strength and good sealing ability due to thread connection as galvanized steel pipe, but also with the advantage of low impurity accumulation, low contamination, low liquid flow resistance and anti-rust, non-corrosive and resistant to acids as HDPE pipe, which is the best substitution of galvanized steel pipe since the latter is often with the problem of rust due to inside zinc coating peeling off after certain working period and causes the rusty water flowing out and harms the people's health. While if use the plastic pipe such as PE, PPR etc, it shall be easily soften and aged when exposed to the sunshine outdoors and the lifetime shall cannot last longer.

The PE-lined Galvanized Steel Pipes followed the Industry Standard for Town Construction of People's Republic of China CJ/T136-2001 Steel pipes of lining plastic for water supply which have been certified by SIRIM of Malaysia (SIRIM QAS International Sdn. Bhd. ) and shall apply for the approval of WRAS from WRC in the near future.

For the out layer of hot dip galvanized welded steel pipe, it passes all tests under Chinese National Standard of GB/T 3091-1993 Galvanized welded steel pipe for low pressure service, which is equal to BS 1387/85 class M. This assures you that the thickness of the steel pipe and its thick zinc coating will result in the long product lifetime.

As to the inside of PE pipe, it passes all the tests under Chinese National Standard of GB/T17219Hygiene and safety evaluation criterion of water delivery and supply equipment and protective materials for life drinking water, which is similar to BS6920 Part II, one of the most stringent standards on cleanliness of water pipe.

The size for PE-lined Galvanized Steel Pipe is from 1/2 to 6 and the working pressure is not more than 1.0Mpa. The standard length is 6Meters, and the length shall be negotiated between the supplier and buyer if the latter has special requirement. Whether threaded in both ends of pipe shall be also negotiated between two parties.

The thickness for inside HDPE pipe with size of 1/2 to 2 1/2 is 1.5 1 0.2mm, 3 to 5 is 2.0 1 0.2mm and 5 is 2.5 1 0.2mm.

Cold water type PE-lined Galvanized Steel Pipe can be used to deliver cold water with temperature under 60 0 .

Hot water type PE-lined Galvanized Steel Pipe can be used to deliver hot water with temperature under 95 0 .
