Spiral Tube

Lining is with plain carbon steel pipe as the foundation, can lined with chemical excellent thermoplastic, the cold tensile or roll forming, it has both the mechanical properties of steel pipe and plastic pipe corrosion resistance, low scale, not easy to the characteristics of the microbial growth, is the transmission of acid, alkali, salt, corrosive gases such as ideal medium pipeline.

Performance characteristics

• Excellent bonding properties

  Through thermal recombination can be closely bonded with aluminum, iron, copper and other metals. Because of the retention of polyolefin properties, hot melt bonding resin with polyethylene, polypropylene also has good bonding properties.

• Persistence of bonding

  After thermal composite bonding, it can still maintain excellent adhesion under harsh conditions such as thermal aging, hot water, cold water and low temperature.

• Simple and easy to process

  It can be produced on the general modified processing equipment of polyethylene and polypropylene, without special production equipment, and the basic production process is similar to that of modified polyethylene and polypropylene.

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 .
