Hot dip galvanized steel pipe

Product Features:

Hot-dip galvanized steel pipe, the base is high-frequency welded pipe, hot-dip galvanized after degreasing, water washing, pickling, rinsing, solvent dipping, drying and other processes

Characteristics of Hot-dip galvanized steel pipe.

The inner and outer surfaces are bright and uniform in color.
The weld seam is uniformly formed, and each tube is explored by eddy currents.
Usually, the zinc number used for hot-dip galvanizing of steel pipes is 0, and the anti-corrosion ability is high.
The surface of each finished hot-dip galvanized steel pipe is treated with special anti-corrosion treatment.

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 .
