 PIPE RING YES

The utility model relates to pipeline construction and is used for pipelines laid in a protective casing during their installation at crossings through roads and railways and other engineering structures.

The prototype of the utility model is a support-guide ring for the pipeline, made in the form of two metal segments fastened together with fastenings along the edges and support elements. US patent No. 2056840, NKI 138-113, 1936.

The prototype pedagogues are as follows. The supporting elements, made in one piece with the metal segment on which they are located, are not insulators and create conditions for the occurrence of intense corrosion during its operation. For large pipeline diameters, two segments are not enough, because they will not provide a proper fit around the pipe, necessary for fixing on the pipe.

In this regard, the technical problem solved by the utility model is to increase the manufacturability of the device and its reliability.

This problem is solved in such a way that in the support-guide ring for the pipeline, made in the form of at least three metal segments fastened together with couplers along the edges and supporting elements.

F16L 7/02

each segment is equipped with a metal socket fixed to it - one or more - for installing the corresponding support elements made of dielectric material and connected to the walls of the nests with transverse clamps.

Private implementations of the proposed device may be as follows.

The fastening of the nests on the segments is carried out by welding - for a firm fixation of the nests.

Cross clamps are made in the form of a bolted connection - one of the possible options for mounting the wall of the socket with the corresponding supporting element used in construction.

The segments are connected to each other with bolts - just like in the previous case, the used method of connecting segments is presented.

The nests on the segments for pipes of small diameter are ring-shaped. This embodiment is due to the required minimum area of the support element.

The sockets for large-diameter pipes are parallelepiped-shaped.

The material of the supporting elements is chosen durable, wear-resistant, with a high value of dielectric constant.

The design of the guide ring is shown in the drawing.

The support-guide ring for the pipeline is made in the form of three metal segments 1, fastened together by bolted joints 2. Each segment 1 has two metal sockets 3 for installing support elements 4 made of dielectric material. Element 4 is attached to the walls of socket 3 by bolt connection 5. Sockets 3

connected to segments 1 by welding. The drawing shows the placement of the device in a protective casing 6. Between the ring and the pipeline there is a gasket 7.

The installation diagram of the support ring on the working pipeline is as follows.

A gasket 7 is additionally installed on a marked place on the pipe for installing the ring to protect the insulation of the pipeline, or several layers of polymer insulation tape are applied. At the same time, its edges should extend beyond the width of the ring evenly on both sides. Then the segments 1 are assembled using bolted joints 2 into an open ring tape. The installation of the ring on the pipe is carried out by closing it with bolted joints 2. In the process of tightening, the absence of closing of the ends of the segments 1 is checked. There should be a gap between the uniformly contracted segments 1. After installing all the rings using appropriate instruments, check the installation quality (tightening torque).

Then carry out pulling this section of the pipeline with the rings installed on it through the protective casing 6.

The proposed device has high adaptability due to the use of reliable elements that are firmly connected to each other and convenient for installation and operation.
