In accordance with a preferred embodiment of the present invention, the components of the tubular lattice parts connected with one another by means of a variety of mechanical connections that provide the appropriate contact details with each other.

The characteristics and advantages of the tube in chemical reactors or heat exchangers in soo is according to the present invention will become more apparent from the following description of common options implementation described by non-limiting example with reference to the accompanying drawings, on which:

- figure 1 shows in plan tube for beam pipes for the chemical reactor according to the present invention;

- figure 2 shows, partially in cross section, part of the connection between the parts tube in figure 1, according to a preferred variant implementation of the present invention.

On the figures of the tubular grating for beam pipes for the chemical reactor according to the present invention everywhere denoted by the reference number 10.

In the embodiment shown in the attached figures, the tube lattice has two parts 11 and 12, having an essentially semi-circular shape, which have been previously machined.

According to the present invention, the perforated panels can be done in multiple parts or components, in accordance with the requirements and dimensions of structures, which are then connected together by mechanical connections.

Thus, perforated panel with large sizes are in the form of several parts, which are connected to each other.

As briefly described in further detail tube, the number of which depends on the size and structural requirements, process until their end, and after this is a mechanically connect. In the example shown in the attached figures, the semicircular parts 11 and 12 are attached to each other by means of a set of bolts 15.

The bolts 15 are inserted into the holes provided respectively in the part 12 and the protruding part 13 of the part 11.

In fact, the part 11 has a protruding portion 13, which is inserted into the corresponding cavity 14 in the part 12.

The connection parts 11 and 12 to complete by means of welded joints between the bolt head 15 and the sheet 12, and an optional welded joints 16' between the parts 11 and 12.

However, in addition to the described example, in order to guarantee the seal, you can use seal of any type or, alternatively, it is possible to obtain a weld seal on the parts of the mechanical connection (which may consist of brackets, screws, wedges, Cams etc).

As a result, the invention provides the possibility of processing separately and parallel components with smaller dimensions, on the machines of smaller size and capacity.

From the description of the clear characteristics and technical advantages of tube for beam pipes for the chemical reactor according to the present invention.
