High quality 15mm hot dipped GI round steel tubing pre galvanized steel tube pipe
Hot-dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, and greenhouse construction.
Galvanized steel pipes are welded steel pipes with a hot-dip or electroplated zinc layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes have a wide range of uses. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, oil heaters, condenser coolers, coal distillation and washing oil exchangers for chemical coking equipment, and pier pipe piles and support frames for mine tunnels.

- Hot-dip galvanizing pipes are made by reacting molten metal with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to first pickle the steel pipe to remove the iron oxide on the surface of the steel pipe. After pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The hot-dip galvanized steel pipe matrix undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant, tightly structured zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix, so it has strong corrosion resistance.
- Cold-dip galvanized pipes are electro-galvanized pipes. The amount of galvanizing is very small, only 10-50g/m2, and its corrosion resistance is much worse than that of hot-dip galvanized pipes. In order to ensure quality, most regular galvanized pipe manufacturers do not use electro-galvanizing (cold plating). Only small enterprises with small scale and outdated equipment use electro-galvanizing, and of course their prices are relatively cheaper. The Ministry of Construction has officially issued a document to eliminate cold-dip galvanized pipes with backward technology and prohibit the use of cold-dip galvanized pipes as water and gas pipes. The galvanized layer of cold-dip galvanized steel pipes is an electroplating layer, and the zinc layer and the steel pipe substrate are independently layered. The zinc layer is thin, and the zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore, its corrosion resistance is poor. In newly built houses, it is forbidden to use cold-dip galvanized steel pipes as water supply pipes.
- The galvanized pipes are often mentioned. The iron pipes used for gas and heating are also galvanized pipes. Galvanized pipes are used as water pipes. After a few years of use, a large amount of rust will be generated in the pipes. The yellow water flowing out not only pollutes the sanitary ware, but also is mixed with bacteria that grow on the rough inner wall. The rust causes the heavy metal content in the water to be too high, which seriously endangers human health.
