Description

(54) PIPING SYSTEM

Vacuum insulating pipelines of prefabricated elements and a shielding coating are known for the detection of gases in a liquid and low-cooled state, located in the casing, the outer pipe of which is insulated with roll-on;

The purpose of the invention is to clarify the compensation of temperature stresses and facilitate the installation of pipelines.

The proposed piping system is characterized in that each element of the insulation is made in the form of IB limited to two ends by conical conical pipe stops, planted with a gap on the pipe to be insulated, and is a support for the shielding strip, the end stops are made in the shape of a truncated cone with the same direction taper.

For a more accurate fit of the two insulating elements, o / porous rings are provided. The end stops and support rings are made split in radial flatness. This will provide a more convenient isolation of flexible pipes, such as electric cables.

FIG. 1 shows the proposed piping system, a partial section; in fig. 2 shows a dionic element; on

FIG. 3 given the option of a system for isolate c.I11 cables.

The piping system consists of insulated pipe1P, groove /, casing 2, insulation elements 3, rollers 4, support pipe 5, end holders (restraints) 6 from lazaml 7, support rings 8, shielding coating 9, Laz W, intermediate holders / /.

The pipeline / is located in the casing 2 (see Fig. 1). The pipeline isolate / consists of individual elements 3, which with the help of rollers 4 arranged around their circumference abut the casing.

The insulating elements 3 consist mainly of a support pipe 5 made of a known thermoplastic synthetic material, planted with a certain gap on the insulated pipeline / (see Fig. 2). At both ends of the support tube 5, ring holders 6 are provided, made of fine stainless high-grade stainless steel.

To reduce thermal conductivity, the end holders can be made with grooves 7, which at the same time provide sufficient cross section to create a vacuum between the pipeline / and casing 2. Support rings 8 are provided in the system. Support pipe 5 between the cones of the mowing winding is applied to the support pipe 5 A shielding lock 9, consisting of an insulating superfoil called a dimplan and used in low temperature technology.

In order to create a full vacuum between the pipe 1 1 and the support pipe 5, the grooves 10 are provided in the latter. The insulated pipe 1 is introduced into the duct with insulating elements either freely or with intermediate holders 11 fixed to the support pipes 5.

If the pipelines / are elastic, such as electric cables, and are supplied in the form of drums with a large amount of wound cable, the support pipe 5, end holders 6 and support rings 5 are divided in a radial plane into two parts, which are welded or glued together during installation (see Fig. 3).
