Part 2 Specification Classification
1. Small Specification
DN15, DN20, DN25, DN32, and DN40 are small-sized galvanized steel pipes, which are frequently used in daily life. Their respective outer diameters are different, respectively 21.3mm, 26.9mm, 33.7mm, and 42. mm and 48.3mm.
2. Medium Specification
DN50, DN65, DN80, and DN100 models belong to medium-sized galvanized steel pipes. Their outer diameters range from 60.3mm to 114.3mm, and the thickness of the pipe wall is also different, such as 3.5mm, 3.8mm, and 4mm. The weight also increases
3. Big Specification
DN125, DN200, DN450 and other models belong to large-scale galvanized steel pipes. Their outer diameters are relatively large, with different sizes such as 140mm and 219.1mm, and the wall thickness and weight also increase accordingly.
Part 3 Classification of Galvanized Steel Pipe
1. Hot-dip galvanized pipe
This type of galvanized pipe is pickled first to remove the iron oxide on the surface. After the pickling is completed, ammonium chloride and zinc chloride are mixed together, used to clean the tank, and then sent to the hot water. dipping tank. For hot-dip galvanized pipe, the coating on it is very uniform and has strong adhesion, and of course the service life is relatively long.
2. Cold galvanized pipe
Cold-dip galvanizing is actually electro-galvanizing, and the amount of galvanizing in it is very small, so the corrosion resistance is much worse than that of hot-dip galvanized pipe. For regular manufacturers, in order to ensure the quality of the pipeline during the production process, they will basically not use electro-galvanizing. For manufacturers with small scale and outdated equipment, they will use electro-galvanized, because the cost will be lower and their own profits will be higher, so everyone should pay attention when buying.
Galvanized steel pipe is a welded steel pipe with a hot-dip or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and oil heaters and condensation pipes for chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, trestle piles, and support pipes for mine tunnels, etc.
