Description

DEVICE FOR CONNECTING PIPES OF COMPOSITE MATERIALS

The technical solution relates to the field of engineering and is intended for use when connecting pipes in the gas and oil industry.

A device for connecting reinforced plastic pipes containing half-cylinders with flanges at the ends, covering the shell of the pipes with collars at the ends, a fastening device for the half-cylinders made in the form of a pipe and sleeve covering them / cm. Description of the invention to the patent of the Russian Federation No. 2094690, IPC F16L 47/00 /. This device is selected as a prototype.

The disadvantages of the known technical solutions are the design complexity: to connect the half-cylinders, additional operations are necessary for pressing them manually or special devices. It is also necessary to manufacture and install the sleeve inside the pipe, for sealing, welding of plastic pipes is necessary, after welding, the winding of the weld with reinforcing material is necessary. In addition, during the operation of pipes in the areas of their joint under bending and tensile loads, a leak may occur due to misalignment of the sleeve, which ultimately leads to loss of the pumped product.

The objective of the proposed technical solution is to simplify the assembly of the structure and increase the tightness of the pipe connection.

The problem is solved in that in a device for connecting pipes made of composite materials containing half cylinders with flanges at the ends, covering the shell of the pipes with flanges at the ends, a mounting device for the half cylinders.

made in the form of pipes that enclose them, collars and enclosing shells made of iodine by mating angles, and at the ends of the half-cylinders there are recesses in which clamping rings are installed, and a seal is made between the ends of the pipes.

The implementation of the flanges of the half-cylinders and the flanges of the enclosing shells at mating angles simplifies the assembly of the structure and provides during assembly coaxial compression of the ends of the enclosing shells.

The execution at the ends of the half-cylinders of the recesses in which the clamping rings are installed, provides a tight pressing of the half-cylinders to the pipe.

The sealing between the ends of the pipes ensures their tight connection.

The device is illustrated in the drawing, where in FIG. 1 shows a device for connecting pipes made of composite materials in longitudinal section.

The device comprises pipes 1, 2, half cylinders 3, 4 with flanges 5, 6 at the ends, covering shells 7, 8 with flanges 9, 10 at the ends, a fastening device for half cylinders 3, 4, made in the form of pipes covering them I. Flanges 5, 6 are made at a mating angle a, at the ends of the semicylinders 3, 4 there are recesses 12 in which the clamping rings 13 are installed, and a seal 14 is made between the ends of the pipes 1, 2.

The device operates as follows.

In this embodiment, the pipes 1, 2 are cylinders lining the covering shells 7, 8 along the entire length.

A seal 14 is installed between the ends of the pipes 1, 2. In this embodiment, a groove 15 is made on the end of the pipe 2 to install the seal 14. It is possible that the seal 14 can be made in the form of an adhesive composition over the entire surface of the ends of the pipes 1, 2 and the covering shells 7 , 8. In this case, the ends of the pipes 1, 2 and enveloping shells are performed at mating angles.

After installing the seal 14 on the enclosing shells 7, 8 of the pipes 1, 2, half cylinders 3, 4 are installed. Adhesive is applied on the mating surfaces. Then, by installing half-cylinders 3, 4 of clamping rings 13 in the recesses 12, half-cylinders 3, 4 are pressed against the female shells of pipes 7, 8 with flanges 9, 10. An adhesive composition is also preliminarily applied to the mating surfaces. Then, an enclosing pipe 11 is mounted on the fixed half cylinders 3, 4 and pressure rings 13. Previously, an adhesive composition is also applied to the mating surfaces.

Using the proposed technical solution allows to simplify the assembly of the structure, increases the reliability and tightness of the pipe connection. Head of the Patent Center Authors: i / y A.N. Yerogov ryiDJi S.M. Kashin 1 D.G. Zhuravlev L.S. Kashin V.A. Devyatkov V.P. Nekrasov L.N. Neganova
