Galvanized Welded Pipes For Construction Projects
Galvanized steel pipe is divided into cold galvanized steel pipe and 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 sixties and seventies, developed countries began to develop new types of pipes, and one by one, galvanized pipes were banned. The Ministry of Construction of China and four other ministries and commissions have also issued a document clearly prohibiting the use of galvanized pipes as water supply pipes from 2000 onwards. Hot-dip galvanized steel pipes are widely used in fire fighting, electricity and highways.
Product Applications
Hot-dip galvanized steel pipes are widely used in the manufacturing industries of construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, shed construction, etc.
Galvanized steel pipe has a welded steel pipe with a hot dip or electro galvanized layer on the surface. Galvanization can increase the corrosion resistance of steel pipes and prolong the service life. Galvanized steel pipe has a wide range of uses, in addition to being used as a pipeline for general low pressure fluids such as water, gas and oil, it is also used as an oil well pipe and oil pipeline in the petroleum industry, especially in the marine oil fields, as an oil heater, condensation cooler and coal distillation and oil washing exchanger pipe for chemical coking equipment, and as a support frame pipe for trestle piles and mining pits, etc.

Product Display
The often said galvanized pipe, the use of galvanized pipe gas, heating with the kind of iron pipe is also galvanized pipe, galvanized pipe as a water pipe, after a few years of use, the pipe produces a lot of rust scale, the outflow of yellow water not only pollute the sanitary ware, and interspersed with unsmooth inner wall breeding bacteria, rust caused by heavy metal content in the water is too high, seriously endangering human health.
