Product Specification

Hot Dipped Galvanized  Round Steel Pipe Pre Galvanized Steel Pipe

Product Description

Hot-dip galvanized pipe-This type of steel pipe is made of molten metal zinc and iron substrate to react with each other to form an alloy layer, so that the plating layer and the substrate are closely attached. The working process of processing hot-dip galvanized steel pipe: first pickling the steel pipe, washing the iron oxide on the surface of the pipe body; cleaning with NH4C and ZnC2 aqueous solution or mixed aqueous solution in the tank, and then placing it in the hot-dip galvanizing tank for hot plating Zinc. The molten plating solution reacts with the substrate to form a zinc-iron alloy layer (the zinc-iron alloy layer has a dense structure and strong corrosion resistance). The steel tube base, pure zinc layer and alloy layer have been fused into one body, so it has strong corrosion resistance. Hot-dip galvanized steel pipe is a hot-dip galvanized welded steel pipe for low-pressure fluid transportation. It is hot-dip galvanized inside and outside on the basis of welded steel pipes, so that the inner and outer walls of the steel pipe are galvanized at the same time. Right and left, hot-dip galvanized steel pipe is widely used as a transportation pipe or metal structure in fire protection engineering, gas transportation, petroleum processing, industry, water conservancy, engineering construction, and residential construction.

Advantage

1. Low processing cost: The cost of hot-dip galvanized antirust is lower than that of other paint coatings;

2. Durable: The zinc layer thickness of the hot-dip galvanized steel pipe meets the standard. In the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained for more than 0 years without having to repair; in urban or offshore areas, the standard hot-dip galvanized anti-rust layer It can be maintained for 20 years without having to repair it.

3. Good reliability: The galvanized layer and the steel are metallurgically combined and become a part of the steel surface, so the durability of the coating is more reliable

4.The toughness of the coating: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use.

5. Protection: Hot-dip galvanized pipe uses high-pressure air to control the uniformity of the zinc layer on the inner and outer surface of the steel pipe, so that each position of the inner and outer surface of the steel pipe can be protected.

6. Save time and effort: The galvanizing process is faster than other coating construction methods, and can reduce the time required for painting on the site after installation.

7. Low initial cost: In general, the cost of hot-dip zinc is lower than the application of other protective coatings, because other protective coatings such as sand paint are labor-intensive processes, and the hot-dip zinc process is highly mechanized and tightly controlled In-plant construction.

8. Inspection is simple and convenient: the hot-dip zinc layer can be visually inspected with a simple non-destructive coating thickness table for testing

9. Reliability: Hot-dip galvanized steel pipe is strictly implemented in accordance with GB / T3091-2008, which limits the thickness of the zinc layer and the corresponding experiments, so its rust-proof period and performance are reliable and predictable.
