What is galvanlized steel pipe?

Galvanized steel pipe is a welded steel pipe with a hot dip or electrogalvanized surface. Galvanizing can increase the corrosion resistance of steel pipe and prolong the service life. Galvanized steel pipe has a wide range of uses, in addition to the transmission of water, gas, oil and other general low pressure fluid pipeline pipe, but also used in the petroleum industry, especially the oil well pipe, oil pipeline of the Marine oil field, the oil heater of chemical coking equipment, the condensing cooler, the coal distillation and washing oil exchanger pipe, and the trestle pipe pile, the support frame of the mine tunnel pipe.

The commonly said galvanized steel pipe, that is, the kind of iron pipe used for gas and heating is also galvanized steel pipe. Galvanized steel pipe as a water pipe, after several years of use, a large number of rust scale will be produced in the pipe. The yellow water flowing out will not only pollute sanitary ware, but also contain bacteria bred on the unclean inner wall, which will cause excessive metal content in the water and seriously harm human health.

The cost of replacing galvanized steel pipe:

Because of the good performance of galvanized steel pipe, people are still in great demand for it, and people often use new galvanized steel pipe to replace the old pipe that has been corroded and cannot be used. Then we have to say that the cost of replacing galvanized steel pipe.

Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, the latter is also advocated by the state can be used temporarily. In the 1960s and 1970s, developed countries began to develop new types of pipes and banned galvanized pipes one after another.
China's Ministry of Construction and other four ministries and commissions also issued a document explicitly banning galvanized pipes as water supply pipes from 2000. Galvanized steel pipes are rarely used for cold water pipes in new residential areas, and galvanized pipes are used for hot water pipes in some residential areas. Hot dip galvanized steel pipes are widely used in fire fighting, electric power and highway.

So today I mainly talk about the cost of replacing hot-dip galvanized steel pipe. The price of hot-dip galvanized steel pipe depends on the specification, material, type, surface quality, finish, dimensional tolerance and so on. This is related to the diameter (size) and thickness of the tube. Galvanized steel pipe is divided into hot dip galvanized and cold galvanized. The price of hot dip galvanized steel pipe is generally 4000-4500 yuan/ton.
