The Difference Between Hot-dip Galvanized Steel Pipe And Pre-galvanized pipe
The difference between hot-dip galvanized steel pipe and Pre-galvanized pipe, the hot-dip galvanized steel pipe is not much different from the galvanized steel pipe. Pre-galvanized pipe also includes hot-dip galvanized steel pipe and electro-galvanized steel pipe, but the electro-galvanized steel pipe has been banned by the state. However, the ban is not really forbidden. It is still used by a small number of people. The hot-dip galvanized steel pipe is a hot-dip galvanized pipe that reacts molten metal with an iron matrix to produce an alloy layer, thereby producing hot-dip galvanizing commonly used in industry Steel Pipe. The following is a detailed description of the differences between hot-dip galvanized steel pipes and galvanized steel pipes.
Hot-dip galvanized steel pipe: In order to improve the corrosion resistance of the steel pipe, Pre-galvanized pipe of the general steel pipe is divided into two types: hot-dip galvanizing and electro-galvanizing. The hot-dip galvanizing galvanized layer is thick, the cost of electro-galvanizing is low, and the surface smoothness is reduced.
Application: Hot-dip galvanized steel pipe is widely used in construction, machinery, coal, chemical, electric power, railway vehicles, automobile industry, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery and other manufacturing industries.
The difference between hot-dip galvanized steel pipe and galvanized steel pipe is that the surface of the galvanized steel pipe has a hot-dip or galvanized welded steel pipe. Zinc plating can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used, in addition to pipelines for general low-pressure fluids such as water, gas, oil, etc., and also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensation of chemical coking equipment. The cooler, the tube for the coal-distilled oil-washing exchanger, the bridge tube pile, the support tube for the mine tunnel, and the like.
