Description

The utility model relates to the field of pipeline construction and can be used in the construction of fixed and movable supporting structures when laying aboveground pipelines, in particular, pipelines for transporting liquid cryogenic products.

Known movable support of the pipeline, containing a hollow box-shaped body, a clamp with tightening fasteners and an elastic element between the pipe and the clamp. The elastic element consists of two rows of tape gaskets located along the edges of the clamp. At the same time, the gaskets of each row are placed around the pipe circumference with a gap, and the size, material of the fasteners and the gasket area are selected from the condition of providing specific pressure on the elastic element at which its elastic properties are preserved, and ensuring horizontal force holding the pipeline in the support, satisfying the ratio :

P _g = f · Q _b · n · K _y · K _n ,

where P _g is the horizontal force;

f is the coefficient of friction;

Q _b - permissible load on one fastener;

n is the number of pairs of fasteners;

K _y - coefficient taking into account the decrease in elasticity;

K _n - coefficient taking into account the uneven distribution of the load on the gaskets (RF patent for utility model No. 31272, IPC F16L 3/10. Publ. July 27, 2003).

An adjustable pipeline support is also known, containing a base and a lodgement, provided with wedges symmetrically located on the base, connected by a screw pair with the possibility of free running on the surface of the base. And the lodgement of the pipeline rests on the strips and ribs, while the ribs are connected to the strips at a right angle, and the strips are installed on the inclined surfaces of the wedges (RF patent for utility model No. 64315, IPC F16L 3/00. Publish. June 27, 2007).

However, these supports are not intended for pipelines transporting cryogenic liquids.

Closest to the proposed in its technical essence is the support of the elevated pipeline, containing a hollow box-shaped body, a clamp with tightening fasteners and an intermediate element between the pipe and clamp (RF patent for utility model No. 122143, IPC F16L 3/10. Publ. 20.11.2012 g.).

But this support is not intended for pipelines transporting cryogenic liquids.

The problem to which the claimed utility model is directed is to create a friction support for pipelines transporting cryogenic liquids.

The technical result of the utility model is to provide frictional retention of the pipeline support in cryogenic temperatures.

The problem is solved in that in the support of an elevated pipeline containing a hollow box-shaped body, a clamp with tightening fasteners and an element between the pipe and the clamp, the hollow box-shaped body and the clamp with tightening fasteners are made of cryogenic steel, and the intermediate element between the pipe and the clamp is made from cryogenic resistant, friction material.

The implementation of the hollow box-shaped body and the clamp with tightening fasteners made of cryogenic steel provides them with the necessary strength when working in conditions of cryogenic temperatures.

And the implementation of the intermediate element between the pipe and the clamp of cryogen-resistant, friction material eliminates the movement in the support of the pipeline when working in conditions of cryogenic temperatures.

In FIG. 1 shows a movable support of an elevated pipeline, general view; in FIG. 2 is a remote element showing the placement of a removable gasket; in FIG. 3 - remote element, demonstrating the placement of the intermediate element on the clamp.

The movable support comprises cryogenic steel, for example, 12X18H10T, a hollow box-shaped housing 1 and a clamp 2 with tightening fasteners 3, consisting of two parts, an intermediate element 4 between the pipe 5 and clamp 2, made, for example, of a cryogenic-resistant, friction material such as PON paronite -B and rigidly fixed on the clamp 2, for example, cryogenic glue "Cryosil" (not shown). At the base 6 of the hollow box-shaped case 1, filled with heat-insulating material (for example, basalt wool) 7, an anti-friction protruding removable gasket 8 is installed, made, for example, of F-4 fluoroplastic and protruding from the edges 9 of the case 1 by a value from 0.5 to 1 , 0 cm.

The support of the elevated pipeline works as follows.

The support is attached to the pipe 5 with a clamp 2 using the tightening elements 3 and the intermediate element 4. In this case, the hollow box-shaped housing 1 of the support with the base 6 with the anti-friction protruding beyond the edges 9 of the housing 1 by the removable gasket 8 is supported by the weight of the pipe 5 on the base surface (building structure) 10, on which is placed a sheet of 11 stainless steel. After mounting the support, it is thermally insulated with a material (not shown) similar to the thermal insulation of the pipeline.

When the cryogenic fluid is supplied, the pipe 5 itself and the intermediate element 4 pressed against it by the pulling elements 3 are mounted on the clamp 2. In addition, due to the cryogenic-frictional and heat-insulating properties of the intermediate element 4 and cryogenic adhesive, the support on the pipe 5 is reliably fixed cryogenic temperatures.

The claimed utility model is intended for both movable and fixed supports, and can be used when laying overhead pipelines transporting liquid cryogenic products.
