Galvanized steel pipe
Galvanized steel pipe is divided into cold galvanized steel pipe and hot galvanized steel pipe. Cold galvanized steel pipes have been banned and the state also recommends the use of the latter temporarily. In the 1960s and 1970s, the world’s developed countries began to develop new types of pipes and gradually banned galvanized pipes. The Chinese Ministry of Construction and four other ministries have also issued a document banning galvanized pipes as water supply pipes since 2000. Galvanized pipes are rarely used for cold water pipes in new communities, and galvanized pipes are used for hot water pipes in Some communities. Hot-dip galvanized steel pipes are widely used for fire fighting, electricity, and highways.

Applications Of Galvanized Steel Pipe
Galvanized pipes have a wide range of uses. In addition to oil and other low-pressure fluid pipelines, it is also used as oil well pipes in the petroleum industry, especially in offshore oil fields, oil heaters in chemical coking equipment, coal distillation, and oil washing converter pipes, bridges, etc. Pipe pile, mining tunnel support frame with pipe, etc. Developed countries in the world started to develop new pipes and continuously banned galvanized pipes.
Most old houses use galvanized pipes. Nowadays, 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 lot of rust and dirt occur in the pipes, and more than just yellow water flows out. It contaminates sanitary ware and is mixed with bacteria that do not lubricate the inner wall. The rust causes excessive heavy metal content in the water, which seriously endangers human health. Galvanized pipes are rarely used for cold water pipes in newly built communities in China, and galvanized pipes are used for hot water pipes in some communities. The often said galvanized pipe is now mainly used to transport gas and heating.
