Problems solved by technology

[0007] The disadvantage of this traditional method is that all steel plate sections are constructed of pre-ceramic thick-walled steel plate, which makes these steel plate sections more expensive than non-ceramic metal sections
[0008] Another disadvantage of this conventional method is that unevenness or seams are created on the inside and outside of the tank at the junction of the paired steel plate segments, which adversely affects the integrity of the tank inner cladding. smoothness and exposes the edges of porcelain-clad steel to material stored in storage tanks
[0009] For steel plate sections fastened together by means of nuts, the areas fastened together by bolting are potentially less resistant to the pressure and weight of the stored material, limiting the height and diameter of storage tanks
[0010] Another disadvantage of this conventional method for constructing porcelain-clad storage tanks is that the steel plate segments must be pre-ceramized and often clad on both sides, a process which is costly in view of the size and weight of these steel plate segments batch process

Embodiment Construction

[0034] Figure 1 shows the gap between two overlapping parts of double-sided porcelain-clad steel plate sections 1, 2 of a thick-walled steel plate 3 held together by two screws 4 with bolts 5, as applied in the current state of the art. Sectional view, the two steel sheet segments have an enamel coating 6 on both sides.

[0035] As known in the prior art, Fig. 2 shows three arc-shaped steel plate segments 1, 2, 7 screwed together with screws 4 and bolts 5, and said three arc-shaped steel plate segments form a storage The annular portion 8 is part of the tank 9 .

Abstract

Method for constructing enamelled storage tanks and silos. Method for constructing enamelled storage tanks and silos, whereby the storage tank is constructed from segments (14, 15,16) of non-enamelled thick-walled steel that are fastened together on the construction site by means of welding, and then clad with a double-sided enamelled flexible thin-walled steel plate (11) on the inside and outside of the storage tank, and whereby the enamelling temperature is at least 500 DEG C.

Description

technical field [0001] The present invention relates to a method for constructing and cladding storage tanks and silos. [0002] More specifically, the subject of the invention is the cladding of storage tanks and silos both internally and externally with porcelain-clad steel plates. Background technique [0003] Such storage tanks are used in industrial applications such as the food industry, agriculture, mining, chemical and petrochemical industries, biofuels, waste treatment, water purification, desalination and similar industries. [0004] It is known that porcelain-clad steel sheets can be used for the construction of storage tanks, whereby both the inside and the outside of the storage tank have a porcelain-clad surface. Porcelain-clad steel on the outside of the storage tank does not require painting, while providing a porcelain-clad steel on the inside of the storage tank provides an inert surface that is resistant to nearly all materials stored therein. [0005] T...
