life of a bolted tank

life of a bolted tank improvement method

life of a bolted tank is currently conservatively designed to be 30 years, which takes into account the sealant life, and the steel life will be longer. If 30 years later, the tank should continue to be used, replacing sealants and bolts.

life of a bolted tank is improved except for the correct operation methods，it is also necessary to prevent and maintain the external vulnerable parts of the bolted tank. The following is an introduction to the external vulnerable parts of the bolted tank:

life of a bolted tank improvement method 1-Anti corrosion of glass lined equipment support:

bolted tank is installed, ear brackets, supports or other supporting parts are sometimes directly installed on the floor, and the floor may be deposited with corrosion media, which will gradually corrode the supporting parts of glass-lined equipment, resulting in changes in the supporting force of each supporting part, eventually leading to glass-lined equipment.

Bolted Steel Storage Tanks

The glass lining layer is damaged by the stress change in the equipment, and the nozzle and connecting pipes are damaged when the stress is serious. Therefore, more attention should be paid to the corrosion protection of equipment support, which can be regularly carried out rust removal, painting, waxing, oil and other anti-corrosion work.

In bolted tank, when steel pipes are connected to the orifice of glass-lined equipment, the pipes will be damaged due to the thermal deformation of glass-lined equipment and the stress caused by heating or cooling of the pipes. In addition, the thermal shock caused by reflux steam and cold liquids can also cause the failure of the glass-enameled layer at the orifice of the enamel equipment.

Also because the nozzle seal is not strict, resulting in reactant overflow, thus corrosion from the outside to the inside of the nozzle, so, for glass-lined equipment nozzle to replace gaskets to ensure the tightness of the nozzle.

life of a bolted tank improvement method 3-Overall external corrosion protection for enamel equipment:

Although the inner wall of the bolted tank has high corrosion resistance to acid and alkali etching, the iron tyre outside the container is not resistant to acid. When the cover or nozzle of the reaction tank is not tightened or the sealing gasket is invalid, acid will leak out and corrode the iron tyre. In addition, the vapor emitted from the raw material leaks through the gasket.

When they encounter the surrounding cold air, it condenses and deposits on the outer edge of the nozzle flange and the edge of the cover flange, corroding the iron tyre and the enameled glass layer, gradually reducing the width of the sealing surface until the effective seal is lost, and more serious condensation acid droplets into the container.

The etched iron tyre causes the scale of glass lining to explode in the container. When powdered materials are put into the nozzle, there will be a problem:

powdered chemicals left in the protruding part of the container, due to humidity and reaction, will also produce local violent reaction caused by glass liner scale explosion phenomenon. Frequent replacement of gaskets and external maintenance of equipment are of great help to the service life of the equipment.

life of a bolted tank reduce the cause

life of a bolted tank reduce the cause 1-Processing stress damage.During the processing of the tank, because of the large amount of internal stress produced by the roll, stamping and welding, these stresses should be eliminated before enameling, such as elimination will not lead to enamel explosion.

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.

life of a bolted tank reduce the cause 2-Unqualified matrix material.

In order to reduce the cost, some manufacturers use Q235 steel instead of the embryo, which directly leads to the gasification of carbon and sulfur in the steel during the enameling process, resulting in a large number of air bubbles between the enamel layer and the matrix, and within the enamel layer, resulting in the reduction of the bonding strength of the enamel. The enamel layer is extremely hot and explosive when it is cold and hot.

So enamel can use carbon and sulphur steel as the embryo body to prevent the explosion of porcelain.

life of a bolted tank reduce the cause 3-Mechanical damage.Enamel has a very poor impact resistance. Any metal or hard object will cause damage to enamel. Therefore, during the use of bolt tank strictly prevent any metal, hard objects fall into the pot, such as clogging, must be dredged with plastic rods, overhaul lid, strictly prevent welding slag melting porcelain surface pits or porcelain explosion.

life of a bolted tank reduce the cause 4-The quality of enamel is not good.Some bolt tank manufacturers have poor production environment, rust removal and dust prevention standards, resulting in poor combination of primer 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, strictly according to the manufacturing rules to ensure the quality of enamel pots.

life of a bolted tank reduce the cause 5-Hydrogen evolution corrosion.The jacket of the bolt tank will scale and rust after a period of time. If the acid detergent is used to remove the dirt or the coolant in the jacket is acidic, the metal will be corroded by hydrogen evolution.
