Steel-plastic composite pipe(Used for heating water)

The constant pressure of high temperature thermal lined public art truly , ensure that the whole pipe lined with plastic does not glue , no glue , no crack . 

Steel pipe adopt international leading high-frequency new welding technology , hot dip galvanized steel pipe for high quality 0 pure zinc plating .

Adopt high purity new PE or PEX raw materials to food hygene and safety of drinking water standard , and meet the requirements of GB/T 13663 standard hot melt adhesive for imported high purity , high quality , high bond strength organic combination of glue , true to ensure the quality of lining . 

Advantages ：

♣  Large endurance capacity      

The steel-plastic composite pipe has the same excellent mechanical strength as the traditional galvanized steel pipe, and has a strong bearing capacity against impact, bending and other external forces.

♣ Good hygienic properties

      The lined plastic pipe (new material PE, PEX) will not cause pollution to the conveyed medium. The inner wall is smooth, free of scale and rust. Ensure water quality is hygienic and meet the requirements of national food hygiene standards (GT/T 17219). Strong adhesion, not easy to fall off, and good sealing performance. No pinholes or cracks, ensuring no leakage.

♣ Installation is simple

      The traditional installation process, and the use of matching pipe fittings with strong sealing performance, the connection is reliable, simple and fast. The pipeline is easy to maintain and the maintenance cost is low.

♣  The plastic layer has good performance

       Low thermal conductivity, heat preservation and energy saving, good low temperature brittleness and small expansion coefficient.

♣  Long service life

      It is not easy to age, and the service life can reach 70 years under normal environment.

PIPE COMPARATIVE

ADVANTAGES AND DISADVANTAGES

Ο/ Comparative		Ο/ Nozzle	Ο/ Inner wall	Ο/ LIFE TIME
	With the Inner Fixed Steel	Within the nozzle has a solid ring, toavoid the water flow on the impact caused by plastic pipe nozzle loss, avoid water pollution.	Internal lining pipe has 100% pure PE plastic pipe , protection of water sources , water better .	Within the service life is long , has a solid ring and plastic layer and three layers of the hot dip galvanized pipe protection .
	Steel-plastic composite pipe	Tube into the antirust processing , but the long-team impact of water , may result in plastic shed , cause water pollution .	Internal lining pipe has 100% pure PE plastic pipe , protection of water sources ,water better .	The service life of the medium .
	Hot dip galvanized steel pipe	Single hot dipped galvanized  pipe , vulnerable to water erosion , lead to rush , and water pollution .	Single hot dipped galvanized pipe , because without the protection of the plastic layer , long-team use can lead to pipe rust , water pollution .	Short service life , easy to erosion by the flow of the lead to rust .
