Since the 1.5-inch-2-inch hot-dip galvanized steel pipe is galvanized on the surface, it can have good weather resistance and corrosion resistance, not only can it make the service strength higher, adjust the groove rate and groove forming time Must not exceed the regulations, symmetrical. Apply force slowly. There are two kinds of corrosion of 1.5-inch-2-inch hot-dip galvanized steel pipe: one is wet; the other is humidity. The galvanized layer of galvanized steel pipe is a common anti-corrosion and anti-rust measure. The unbalanced supply and demand of galvanized steel pipe can effectively improve the service life. High-quality galvanized square tube with smooth and clean surface and metallic texture. If nothing else, this is a normal problem. In fact, it is a pressure processing process that uses hydraulic or mechanical methods to apply a certain force to the inside of the steel pipe to expand the diameter of the steel pipe axially outward.

The inner circumference of the 1.5-inch-2-inch hot-dip galvanized steel pipe remains stationary for a period of time. This is the stable pressure holding phase required by the equipment and expansion process. The last stage is called offloading and regression. It is because of the different additions of these galvanized square tubes that they create many different physical and chemical properties. The iron and zinc diffused into the molten zinc solution produce the intermetallic compound FeZn13. It sinks into the bottom of the hot-dip galvanizing pot, that is, zinc slag.
