Product Description
Hot-dip galvanized steel pipe: The hot-dip galvanized steel pipe is
first pickled on the steel parts. In order to remove the iron oxide
on the surface of the steel parts, after the pickling, it is passed
through ammonium chloride or zinc chloride aqueous solution or
ammonium chloride and zinc chloride The mixed aqueous solution tank
is cleaned and then sent to the hot dip plating tank. Hot-dip
galvanizing has the advantages of uniform coating, strong adhesion
and long service life.
Hot-dip galvanized steel pipe
Cold-dip galvanized steel pipe: Although cold galvanized steel pipe
is rarely used on a large scale now, since we are talking about the
difference, it will naturally be introduced. Cold galvanizing is
also called electro-galvanizing, which uses electrolytic equipment
to remove oil After pickling, put it in a solution of zinc salt and
connect it to the negative electrode of the electrolysis device.
Place a zinc plate on the opposite side of the pipe fitting,
connect it to the positive electrode of the electrolysis device and
turn on the power supply. Use the current to move from the positive
electrode to the negative electrode. A layer of zinc is deposited
on the pipe fittings, and the cold-plated pipe fittings are
processed first and then galvanized.
Hot-dip galvanized steel pipe vs cold-dip galvanized steel pipe:
1. Different manufacturing processes
Hot-dip galvanized steel pipe is to make the molten metal react
with the iron matrix to produce an alloy layer, so that the matrix
and the coating are combined.
Cold-galvanized steel pipe is a cold-galvanized coating which is
mainly used for anti-corrosion through electrochemical principles.
2. Different equipment required
Hot-dip galvanized steel pipe: pickling equipment, bottom-drawing
annealing furnace or bell-type annealing furnace.
Cold galvanized steel pipe: electrolysis equipment.
3. Different performance
Hot-dip galvanizing: long-lasting and anti-corrosion, the standard
quality of hot-dip galvanizing anti-rust thickness makes it have
excellent durability; the toughness of the coating is strong, and
the hot-dip galvanizing layer forms a unique smelted metal
structure. The structure can withstand mechanical damage during
transportation and use.
Cold galvanizing: has excellent environmental performance. Most
cold galvanizing solvents and thinners do not contain highly toxic
organic solvents, and the cold galvanizing process also reduces the
volatilization of organic solvents, reduces drying energy
consumption, and is beneficial to environmental protection.
4. The thickness of the galvanized layer is different
The zinc layer of hot-dip galvanized steel pipe is relatively
thick, with a thickness of more than 10um. Although the surface is
bright, it is rough and spangles will appear.
The zinc layer of electro-galvanized (cold galvanized steel pipe)
is very thin. As long as the thickness is 3-5um, although the
surface is smooth, it will appear dark and dirty, with good
processing performance and insufficient corrosion resistance.
5. Different applications
Hot-dip galvanized steel pipes are widely used in electric power
towers, communication towers, railways, highway protection, street
lamp poles, marine components, building steel structural
components, substation ancillary facilities, light industry, etc.
due to their good anti-corrosion properties.
Cold-galvanized steel pipe is the main development direction of the
environmental protection of heavy anti-corrosion coatings.
