Description

GI1 PREVIOUS PIPELINE

The utility model relates to the chemical and oil and gas industry and is used, in particular, for transferring a gaseous medium from a borehole to a gas analyzer station.

A heated pipeline is known, consisting of a main pipeline and a satellite pipeline, the latter being made in the form of a half cylinder located with a gap relative to the main pipeline and tightly attached by the edges to it. The heating pipeline is insulated. (copyright certificate No. 1634939, IPC: F 16 L 53/00, published in B.I. No. 10 for 1991).

The peda of the above technical solution is the incomplete contact of the coolant with the transported product.

Also known is a flexible heated pipeline containing an electric heating element in the form of a spring reinforced spiral, the ends of which are mounted in fittings for input and output of the transported medium, and the fittings are installed at the ends of the pipe. The heating pipeline is covered with thermal insulation (copyright certificate No. 514988, IPC: F16L 53/00, published in BI No. 19 for 1976).

A pedagogue of the above technical solution is the direct contact of the transported medium with the heating element, which affects its service life and the quality of the transported product.

The creation of a useful model is based on the task of developing such a design of a heated pipeline that eliminates the disadvantages of the prototype and allows you to maintain the initial temperature regime of the transported medium in the pipeline due to automatic control of heat generation in response to an increase or decrease

IPC: F16L 53/00

ambient temperature, which, in turn, provides reliability, durability and stability of the pipeline.

This object is achieved in that the known flexible heated pipe, equipped with an electric heating element and enclosed in a heat-insulating casing, is equipped with a flexible tube mounted integrally with the heating element. The heating element is made in the form of a self-regulating heating tape located along the entire length of the flexible tube and enclosed with it in a metal braid.

A distinctive feature of this design is that

a self-regulating naphtha tape is applied in the form of a semiconducting self-regulating} lamination matrix with -.

allowing automatically adjust the heat generation by the matrix in response to an increase or decrease in the temperature of the transported medium.

The flexibility of the pipeline is ensured by the use of, for example, a PVC polymer tube.

The entire combination of the above design features and their relationship is aimed at solving the problem.

The present utility model is illustrated in the drawing, where

in FIG. 1 - shows a General view of the device

in FIG. 2 - section aa

The flexible heated pipe contains an electric heating element in the form of a self-regulating heating tape 1 located along the entire length of the flexible pipe 2, enclosed in a metal braid 3 and placed in a heat-insulating casing 4. Outlets are made on both sides of the flexible heated pipe

flexible tube 2 to connect it. Tape 1 is made in the form

A flexible heated pipeline is connected at one end of flexible tube 2 to the well, and at the other end to a gas analyzer station in a mobile laboratory. The self-regulating heating tape 1 is connected to the mains from one point. The exhaust gas from the well through a flexible pipe 2 is carried out by a compressor installed in a mobile laboratory.

When the gas medium passes through the flexible tube 2 of the flexible heated pipe, it either heats up or cools, depending on the temperature of the gas medium, which entails a corresponding reduction in current paths in the self-regulating heating tape 1 in this section and a decrease in heat generation, or vice versa, an increase in current paths paths during its cooling and increased heat dissipation. Thus, the temperature of the gas medium is maintained while passing through a flexible tube. 2

The presence of a metal braid 3 located around a self-regulating heating tape 1 and a flexible tube 2, as well as a heat-insulating casing 4 helps to stabilize and maintain the temperature regime in a flexible heated pipeline.
