Round ERW Pipe For Greenhouse Hot Dipped Galvanized Steel Pipe
Product Description
This kind of steel pipe is formed by the interaction of molten zinc and iron matrix to form an alloy layer, which makes the coating and the matrix closely combined. The working process of hot-dip galvanized steel pipe processing is: first, the steel pipe is pickled and the iron oxide on the surface of the pipe body is cleaned; then, the steel pipe is washed with nh4c and znc2 aqueous solution or mixed aqueous solution, and then put into the hot-dip galvanized tank for hot-dip galvanizing. The zinc iron alloy layer is formed by the reaction between the plating solution and the substrate. The steel pipe base, pure zinc layer and alloy layer are melted into one, which has strong corrosion resistance. Hot dip galvanized steel pipe is a hot dip galvanized welded steel pipe for low pressure fluid transportation. On the basis of the welded steel pipe, the inner and outer walls of the steel pipe are galvanized at the same time. Left and right hot-dip galvanized steel pipes are widely used in fire engineering, gas transportation, oil processing, industry, water conservancy, engineering construction, residential construction and other industries.
Advantage
1. Low processing cost: the cost of hot-dip galvanizing antirust paint is lower than other coatings;
2 Durable: the zinc layer thickness of hot-dip galvanized steel pipe meets the standard. In suburban environment, the standard hot-dip galvanizing antirust thickness can be maintained for more than 0 years without repair; in urban or offshore areas, the standard hot-dip galvanizing antirust layer can be maintained for 20 years without repair.
3. Good reliability: the galvanized layer is metallurgical combined with the steel to become a part of the steel surface, and the durability of the coating is more reliable
4. Coating toughness: the galvanized layer forms a special metallurgical structure, which can withstand the mechanical damage during transportation and use.
5. Protection: the high-pressure air is used to control the uniformity of the zinc layer on the inner and outer surface of the hot-dip galvanized pipe, so that every position on the inner and outer surface of the steel pipe can be protected.
6. time saving and labor saving: the galvanizing process is faster than other coating construction methods, and the time required for field coating can be reduced after installation.
7. Low initial cost: generally, the cost of hot-dip galvanizing is lower than that of other protective coatings, because other protective coatings, such as sand coating, are labor-intensive processes, and the hot-dip galvanizing process is highly mechanized and tightly controlled in plant construction.
8. Simple and convenient inspection: the hot-dip galvanizing layer can be visually inspected with a simple non-destructive coating thickness gauge
9. Reliability: the hot-dip galvanized steel pipe is strictly in accordance with GB / t3091-2008, which limits the thickness of zinc layer and corresponding tests, and its rust prevention cycle and performance are reliable and predictable.
