life of a bolt tank

The life of a bolt tank is currently estimated at 30 years. The 30 year is to consider the service life of sealants, and the life of steel will be longer. If 30 years later, the tank should continue to be used, replacing sealants and screws.

In the process of machining stress damage and in the processing of the tank, a large amount of internal stress is produced by the rolls, punching and welding. These stresses should be completely eliminated before the enamel. If the elimination is not complete, the enamel porcelain will be detonating. This damage often occurs in the first three months after being put into use. Therefore, heat treatment or aging treatment of the embryo body can prevent the explosion of porcelain.

In order to reduce the cost of the matrix material, in order to reduce the cost, some manufacturers use Q235 steel to replace the carbon and sulfur in the steel directly. It makes the enamel layer and the matrix and the enamel layer formed a large number of bubbles, which leads to the reduction of the enamel bonding strength. Enamel layer in cold and hot change, extremely explosive porcelain. So enamel can use carbon and sulphur steel as embryo body to prevent exploding porcelain.

Mechanical damage and enamel impact resistance are very poor. Any metal and hard objects impacting on it will cause enamel breakage. Therefore, in the process of using the enamel tank, any metal and hard material will fall into the tank. If the material is blocked, it is necessary to use plastic bars to dredge, cover the cover of the pot when overhauled, and to prevent the appearance of small pits or explosive porcelain with the slag fused to the porcelain surface.

The poor quality of enamel production and the poor production environment of some enamel tank manufacturers fail to meet the standard of rust removal and dustproof, resulting in poor combination of base glaze and substrate. Some reduce the number of times of firing, increase the thickness of each layer, cause too much internal force, and affect the service life of enamel pots. Therefore, the quality of enamel can be guaranteed strictly according to the manufacturing rules.

The corrosion of hydrogen evolution and the jacket of life of a bolt tank will be fouling and rusty after a period of use. If the acid remover is used to clean the dirt or the coolant in the jacket, it will cause the hydrogen evolution corrosion of the metal.

Enamel can be coated on the surface of low carbon steel with high silicon content. The enamel is baked on a high temperature of about 900 C to make the enamel dense on the surface of metal steel. Because the mechanical and physical properties of the two kinds of materials are different, the cause of the enamel tank is also varied, and there are the following reasons.

Mechanical damage: Enamel impact resistance is very poor. Any metal and hard objects impacting on it will cause enamel breakage. Therefore, in the process of using the enamel tank, any metal and hard material will fall into the tank. If the material is blocked, it is necessary to use plastic bars to dredge, cover the cover of the pot when overhauled, and to prevent the appearance of small pits or explosive porcelain with the slag fused to the porcelain surface.

The substrate material is not qualified: in order to reduce the cost, some Q235 steel is used to replace the carbon and sulfur in the steel directly. It makes the enamel layer and the matrix and the enamel layer formed a large number of bubbles, which leads to the reduction of the life of a bolt tank, the enamel layer in the cold and hot change, the extremely explosive porcelain, so the enamel cans are selected with carbon and sulfur low steel. Making embryo physical energy to prevent explosive porcelain

The quality of the enamel is poor: the production environment of some enamel cans is poor, the rust and dustproof can not reach the standard, the combination of the base glaze and the substrate is not good, and some reduces the thickness of each layer to increase the thickness of each layer, so that the internal force is too large to affect the service life of the enamel cans, so the quality of the enamel cans is strictly manufactured to ensure the quality of the enamel cans.

Electrostatic puncture: the enamel tank stirs the liquid with the suspended substance, the suspended substance and the enamel's strong friction, and the suspension itself produces friction, which produces a lot of static charge. High static charge has a strong puncture effect on the enamel, which leads to the enamel pitting, because this stirring speed should not be too fast.

Hydrogen evolution corrosion: the jacket of enamel cans will be fouled and rusty after a period of use. Because of the densification of enamel, the enamel can not spread outward again. So when Hz accumulates to a certain degree, the enamel will break up when the fixed power is formed, so it must be added with a buffer when the cleaning and scaling is used, if the value of the enamel can is higher or not. Easy to replace or even corrosive perforation, it is necessary to use high quality cleaning agent with low corrosion rate to avoid serious consequences caused by improper cleaning operation.

Thermal stress damage: enamel pot is calcined at 900 centigrade high temperature, after cooling, enamel and steel plate are bonded together, because the line expansion coefficient and elongation of enamel are less than steel plate, so the deformation amount of enamel glass is less than that of steel plate, and the enamel is constrained by the steel plate to produce pressure stress. After the life of a bolt tank is made, the glass lining is precompressed. While the steel plate has pretension stress, because the prestress is related to the coefficient of linear expansion and the elongation, the coefficient of linear expansion and the elongation are closely related to the temperature. Therefore, the working temperature of the enamel tank has a great influence on the use of enamel cans.

If the stress produced by the temperature is larger than that of the use stress, the enamel will be destroyed. Therefore, enamel enamel layer is cold, hot and explosive porcelain, so the enamel tank has temperature tolerance: temperature 200, temperature change: cold shock

Stress damage: during the processing of the tank, a large amount of internal stress is produced by the reel, stamping and welding. These stresses should be completely eliminated before the enamel, such as the removal of the enamel porcelain, which often occurs in the first three months after the use of the life of a bolt tank, so the heat treatment or aging treatment of the embryo can prevent the explosion of porcelain.
