What is the difference between hot- dip galvanized steel pipe and galvanized steel pipe?
Galvanized wire tube: dedicated for threading and wire
Galvanized steel pipe: for water and gas pipelines
Galvanized steel pipe and galvanized steel pipe are divided into two materials: hot-dip galvanized and galvanized
The hot-dip galvanized layer is thick, and has the advantages of uniform coating, strong adhesion and long service life.
Galvanized is low cost, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipe.
Galvanized line pipe is a kind of steel material pipe, which can be subdivided into two types: full galvanized inside and outside and galvanized outside. The usual galvanized steel pipe is a steel pipe only in zinc, which is specially used for threading pipes. For large projects, it is useful for galvanized steel pipe threading pipes.
Welded steel pipe with hot dip galvanized or galvanized coating on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of the steel pipe and prolong its service life. Galvanized pipes have a wide range of uses. In addition to being used as pipeline pipes for water, gas, oil and other general low pressure fluids, they are also used as oil well pipes, oil pipelines in the oil industry, especially offshore oil fields, oil heaters for chemical coking equipment, and condensation Pipes for coolers, coal-distilled wash oil ex-changers, as well as trestle pipe piles, pipes for support frames of mine tunnels.
