(54) PIPE-SHIPANGO

one

The invention relates to the production of fiberglass pipes.

Glass-plastic pipes are known - shells consisting of annular closed pipes 1 fastened together.

The disadvantage of these pipes is the low specific strength and rigidity of the structure.

The purpose of the invention is to increase the specific strength and rigidity of the structure.

The goal is achieved by the fact that the sa designs are made in the form of a package of one-piece hollow tore shells of the shaped profile in plan, aligned and fastened to each other along the side surfaces by means of glue, rings or linings.

FIG. Figure 1 shows schematically the proposed construction of a shpangot pipe, the main variant; in fig. 2-11 - the same, various modifications.

Shchpangout pipe 1 (Fig. 1) consists of annular closed hollow cores fastened together. They are made in the form of solid-end face shells with a triangular profile 2 in plan. Solid end shells are fastened to each other along inclined surfaces 3 with adhesive mass.

In order to increase the specific strength, rigidity and thermal protection of the structure, closed annular cavities 4 are filled with a heat-shielding mass 5, for example, foam plastic, and the entire package (s) of the combined end shells of the v- and l-shaped profile is additionally fixed in the plan shells of the corresponding profile.

10 Gaps 6 in mates of combined torus shells or their package (s) through aperture 7 are filled with glue mass, rings 8 or sector slips, fastened together with each other and torus shells by threaded elements.

The cross section of a pipe-pipe made up of a combination of owl-type and L-shaped profile can be in the form of a parallelogram (Fig. 4), a trapezium (Fig. 5), a rectangle (Fig. 7), or any combination of them. 2Q FIG. 6 shows a view of a pipe with a square cross-section.

The circular V-shaped closed profile in the plan can be included in the pipe-band in combination with the closed torus profiles of the rectangular 9, rhombic 10 or parallelogram 11 in the plan (Fig. 8, 10 and I), but also in any combination (Fig. 9) of them.

So can. pipe frames of any geometrical dimensions should be made, the number of closed by a triangular profile, the angles of inclination, their material and the modes of its heat treatment are determined by a special calculation depending on the actual loads and operating conditions.
