Abstract

The technical problem addressed by the invention is that of obtaining a metal-plastic pipeline with greater load-carrying capacity and low hydraulic wastage, improving the stability of the production process, and facilitating in technical terms the production of large-diameter pipes. The proposed metal-plastic pipeline (4) is produced by winding at least two perforated strips (5, 6) around a rotating former, joining the two strips, and subsequently pouring on a polymer material (7). Each or only one of the perforated strips is provided with projections (20) facing into the gap between the strips. The perforated strips are joined by welding through the projections (20) or strip edges along a spiral. Once the finished pipe has cooled down, it is cut into sections of equal length and the ends are machined by milling the outer polymer layer to produce a conical profile onto which the coupling sleeve (8) can fit; the latter consists of a perforated metal casing (9) encased in a block of polymer material (7) and heating elements (10). Alternatively, adapter elements (14) comprising a tubular perforated element (15) encased in a block of polymer material (7) and heating elements (10) are joined to the ends, or connecting flanges (14) are fitted, comprising polymer tubes (4) or adapters (14) for a coupling sleeve (12) which is provided with a thrust collar and encased in a block of polymer material (7). The reinforcing casing of the connecting elements (8, 14) has the same strength as the reinforcing casing of the connected pipes. The type of connecting element is determined by the configuration of the pipeline being manufactured.

When framing an aromatic cassette from a tape, consisting of elements of a separate and transverse armament, the latter are connected to the other. 4 On the connection side, the pipe uses connectors, couplings and flanges to ensure that there is a rigid connection to the other parts.

When manufacturing an aromatic pipe, it is necessary to navigate the territory in two ways, which is more and more widespread. In general, displaces the friend to the other friend in the general direction or to the land at different angles. The size of the gap between the divided bands is at a height greater than the width. The belts are connected between the simple and fastest access via bus or bypass -

Spreads on the band are obtained by repressing them by bending the carved part or by other well-known methods.

Formation of the external and internal partitions of the pipe is carried out on the rotating devices with the system of cooling, for example, is free from heat.

A rigid connection is made by the welded and other well-known methods. 6

The main part of the pipe is set up by means of a hard-wired connection of the terminal accessories and the use of fittings and couplings. The flange connection is used for the storage of end pipes with interconnected containers, in the place of the placement of foreign equipment, equipment and other devices.

Connecting elements (fittings, flanges and couplings) are integrated into the pipe fittings. The connection can be carried out in the process of manufacturing the pipe, pipe and in the process of discharging the pipe in the place of disposal.
