Galvanized line pipes are specially used for threading and conducting wires, while galvanized steel pipes are used for water, coal, and gas pipelines.
Galvanized steel pipe and galvanized line pipe are divided into two materials: hot-dip galvanized and electro-galvanized. The hot-dip galvanizing layer is thick, which has the advantages of uniform coating, strong adhesion and long service life. The cost of electro-galvanizing is low, the surface is not very smooth, and its corrosion resistance is much different than that of hot-dip galvanized pipes.
Performance of galvanized line pipe and galvanized steel pipe:
Galvanized line pipe is a kind of steel pipe. Galvanized line pipes can be divided into two types: full galvanized inside and outside and galvanized outside. The usual galvanized line pipe is the steel pipe with only the galvanized inside, which is dedicated to the threading pipe.
Galvanized steel pipes are welded steel pipes with hot-dip galvanized or electro-galvanized layers on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and prolong the service life. Galvanized steel pipes are used in a wide range of applications. In addition to line pipes for conveying water, gas, oil and other general low-pressure fluids, they are also used as oil well pipes and oil pipes in the petroleum industry, especially offshore oil fields, as well as oil heaters and condensate for chemical coking equipment, pipes for coolers, coal-distilled wash oil exchangers, pipe piles for trestle bridges, pipes for support frames of mine tunnels, etc.
