Galvanized steel pipe, also known as GI steel pipe, can classified into two kinds. One is hot dipped galvanized steel pipe, the other is electric steel pipe. Advantage of hot dipped galvanized steel pipe is that the galvanized coating will be thicker, and the zinc coating will be fairly and can stick to the pipe body better. And life span of hot dipped galvanized steel pipe is longer. For electric steel pipe, the cost will be cheaper than hot dipped galvanized steel pipe, but it also has its disadvantage. The surface of the electric steel pipe is not smooth. And its anti-corrosion function is not as good as hot dipped galvanized steel pipe. In order to approve steel pipes quality and extend its life span, galvanized steel pipe is widely used in our daily life. We can see that GI steel pipe is widely used for transport gas, heat, water pipe, and for construction usage. And most of scaffolding are GI steel pipe.

Galvanized steel pipe USES is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube, etc. Hot dip galvanized steel pipe is widely used in all kinds of modern manufacturing industry.

Galvanized steel pipe mainly used in transmission of coal gas, steam. It was used as water pipe, but after several years past, there were many rust in the pipe, and water get yellow color for carrying iron oxide. The water not only polluted dishes or other sanitary ware, but also carrying bacteria produced in the internal surface which not smooth . As a result of the corrosion, the water contains heavy metal element is too much and is harmful to peopleâ??s health. For this reason, developed countries gradually� banned it using as water pipe since 1960s. Material Standard: ASTM, ASME and API 5L PSL2; Size: 1/2 inch to 12 inch, 14 inch, 16 inch, 18 inch, 20 inch, and 24 inch for seamless; Wall thickness: SCH 10, SCH 20, SCH 30, SCH 40, STD, XS, SCH 60, SCH 80, SCH 100, SCH120, SCH160, XXS; Length Range: 20 FT (6 meter), 40FT (12 meter)or customized; Form: Round, Square, Rectangular Etc Ends Type: Beveled ends, Plain ends; End Protection: plastic Caps or iron Caps; Surface Coatings: Natural, Varnished, Black painting, 3PP, FBE and 3PE, Cladding and Lined etc.
Cold galvanized is electric galvanized, galvanized amount is very little, only 10-50g/m2, its own corrosion resistance is much different than hot galvanized steel pipe. Regular galvanized steel pipe manufacturers, in order to ensure quality, most do not use galvanized (cold plating). Only those small enterprises with obsolete equipment use electrogalvanizing, of course, their price is relatively cheaper. In the future, it is not allowed to use cold galvanized steel pipe as water and gas pipe. Material Standard: ASTM, ASME and API 5L PSL2; Size: 1/2 inch to 12 inch, 14 inch, 16 inch, 18 inch, 20 inch, and 24 inch for seamless; Wall thickness: SCH 10, SCH 20, SCH 30, SCH 40, STD, XS, SCH 60, SCH 80, SCH 100, SCH120, SCH160, XXS; Length Range: 20 FT (6 meter), 40FT (12 meter)or customized; Form: Round, Square, Rectangular Etc Ends Type: Beveled ends, Plain ends; End Protection: plastic Caps or iron Caps; Surface Coatings: Natural, Varnished, Black painting, 3PP, FBE and 3PE, Cladding and Lined etc.
The molten metal reacts with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanized steel pipe is first pickling, in order to remove iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing steel pipe has the advantages of uniform coating, strong adhesion and long service life. Most of the processes in north China are zinc plating with direct coil pipe.
