Shenzhen profile manufacturers tell you what is galvanized steel pipe

Shenzhen profile manufacturers have expected a uniform coating thickness, which is unlikely in practice. Therefore, the measurement of the amount of adhesion cannot be determined by a single part, and it is necessary to measure the uniform weight of zinc attached per unit area. The so-called solidity is the adhesion between the galvanized layer and the steel. It is mainly requested that the galvanized component has the property of not being peeled off during finishing, transportation, storage and operation. The common inspection method includes the hammering method, the squeezing method, the winding method, etc. .

There is a manufacturing process that compares the special unbonded prestressed steel strands, which is to stop the epoxy coating or galvanizing treatment on the steel strands in the bare state. It effectively separates the concrete from the strands. There is also a longer-lasting advantage in the length of use. Sometimes there may be some technical problems during the construction process. For example, the beam is not lifted smoothly, and the prestressed steel strand can not be used normally. At this time, the technician is required to stop the inspection of the entire construction component to see if there is any foreign matter. It is stuck, or the machine seat hole and the screw rod are further smooth, and some of the problems are dealt with, so that the role of the prestressed steel strand can be exerted even more.

If the steel used in hot-dip galvanizing angle steel is originally rough and rough, there are rust pits or obvious rolling streaks, after the hot-dip galvanizing is completed, the appearance is generally not smoother than the original. The composition of the steel may also affect the formation of the Zn-Fe alloy phase layer due to the Saint-Delin effect, resulting in excessive or uneven formation. The owners of the home improvement device parts are concerned about the common angle steel device method, etc. The latest hardware and building materials devices are related to the introduction. It is understood that the main consumption characteristics and demand of angle steel have been widely used in society, especially in transportation and dissemination. It is more frequent in the industry as a container rack and warehouse.

Galvanized steel pipe is a steel that is manufactured by stopping the galvanizing operation on the surface of some metals and alloys. This process can achieve good aesthetics and rust-proof performance. Today, the most common method is hot-dip galvanizing. . The galvanized strip has stable performance, average coating, strong adhesion and long service life. The quality of galvanized steel strip is the one that we take seriously. How to distinguish its quality? We need to check the quality of the materials used in the manufacture of this galvanized steel pipe, and whether the disposal process can meet the requirements. Wait. The amount of galvanizing is directly related to its anti-corrosion ability, and the galvanizing amount can prolong the service life of galvanized steel strip.

However, a little understanding of the galvanized steel pipe manufacturers in Shenzhen profile manufacturers know that any metal will be in a normal environment, it will show mildew, rust, if you want to slow down the mildew of galvanized steel pipe should be reasonably registered, usually In a ventilated and boring environment, as the metal encounters the water in the air, it will rust and be oxidized for a long time. So how to deal with this problem from Kenben, it must be thought of from the beginning of the strip plating. Generally speaking, the hot-dip galvanizing process strip steel product is relatively less oxidized than the electro-galvanized steel tube. Because the hot-dip galvanizing process is coated with a thick layer of zinc on the strip surface, even if it consumes white enamel, it will not affect the normal. use.

The consumption of galvanized steel pipes often turns black. Many users do not understand and feel that there is a problem with the quality. If they can be denied, this will not affect the normal operation. The blackening of the galvanized steel pipe is mainly formed by oxidation. The normal zinc oxide is white ZnO, and ZnO2 black can be formed under the condition of lack of oxygen. The transparent conductive film of ZNO has good transparency and good conductivity. ZNO2 two transparent conductive films, good absorption and heat insulation. Galvanized round steel, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro-galvanizing. Among them, the hot-dip galvanized galvanized layer has the advantages of average coating, strong adhesion and long service life.
