I need advice

Sliding supports are pipeline elements used to fix polyurethane foam pipes with a galvanized steel shell in a given position. They are used for laying pipelines of above-ground and channel types related to heat and water supply systems.

Sliding supports for pipes do not have thermal insulation; the fastening of pipes to these metal structures does not provide for their rigid fixation with a welded joint.

Application of supports for pipes in polyurethane foam

Sliding support designs easily support designated sections of pipelines while absorbing the pressure of vertical loads that are created by temperature or pressure fluctuations within the system.

Pipes in PPU insulation are laid on a support. The pipe is fixed by tightening it with clamps.

Protection of the outer shell from damage during operation is ensured by laying damping material (polyethylene, rubber) between the outer shell of the pipe and the lower part of the heating network pipeline support.

The pipes installed on sliding supports are not rigidly attached, but have the ability to freely move in a longitudinal position. This allows the pipes to avoid sagging or excessive stress when changing modes in the operation of the heating main.

Pipelines of heating networks are dynamic systems, the significant mass of which, as well as changes in pressure and operating temperature loads, lead to constant axial and transverse movements and for their stable maintenance in working planes, self-compensation, protection from vibration and movement within the design parameters, special devices are used , including the so-called sliding supports (movable supports, movable support) or an articulated movable support.

The main purpose of a sliding support for pipes (sliding support PPU), used for PPU insulated pipes of heating networks of overhead or channel installation methods, is to vertically support a certain straight section of the pipeline and protect the insulating and thermal insulation coating of the PPU pipe from damage during operation. The difference between this type of movable sliding support is that the sliding support (supports for polyurethane foam pipes), unlike the principle of operation, the support is stationary and works without fixing the polyurethane foam pipe.

Sliding supports (moving supports for heating networks) are designed for PPU heating network pipelines, both underground and above-ground installation and cover the entire range of diameters of pre-insulated pipelines within nominal diameters from 32 to 1220 mm. According to the route of the heating network pipeline, taking into account the slope of the heating main and the distribution of the load over measured sections, concrete bases with steel insert plates are installed, to which the finished sliding support products (movable support) are welded.

Movable pipeline supports, sliding supports, supplied by the RosMTS group of companies, consist of a base made of a channel and two pairs of narrow semicircular supports (clamps) made of a steel strip, the lower of which are attached to it, and the upper holders are attached to the lower ones with bolts and nuts.

Production of sliding supports. Sliding support

During the installation of the sliding supports, a polyurethane foam insulation pipe with a steel outer shell is laid on the lower pair of half-rings lying at the base of the movable support for pipes. Then the second pair of half-rings from the strip is placed on the polyurethane foam pipe and attached to the bottom pair. That's all for installing the sliding supports. To protect the outer steel shell of the polyurethane foam pipe from damage from friction, an insulating wear-resistant material (usually rubber) is laid between it and the support. To protect against corrosion, the sliding supports (movable clamp support) are coated with an anti-corrosion coating. The dimensions and design of the sliding support, sliding clamp support for polyurethane foam pipes of insulated pipelines of heating networks are determined in the table of GOST 30732-2006.

Movable supports GOST?

Movable supports are manufactured in accordance with GOST 30732-2006.

Sliding weight support?

The weight of the sliding support is directly dependent on the diameter.

GOST sliding bearings?

Sliding supports are manufactured in accordance with GOST 30732-2006.

Distance between sliding supports?

The distance between the sliding support;

Sliding supports must be installed at a strictly defined distance, which depends on several criteria and is calculated separately for each type of pipeline. The distance between sliding supports is influenced by several criteria:

• Outer diameter of pipes. The larger the diameter, the greater the distance between the sliding supports.
• Pipeline type. Sliding supports under cold water pipes are installed at a greater distance than at high temperatures.
• Pipe location. For a vertical pipeline, the distance between the sliding supports should be 10% greater than in sections with horizontal pipes.

Advantages of pipeline supports with polyurethane foam insulation

PPU supports are used for the construction of pipelines from pipes insulated with polyurethane foam. They provide reliable placement of pipes, rigidly fixing their position along the axis. The distance between the supports is determined by the features of the local topography and the placement of compensators designed to absorb fluctuations in pipe lengths when temperature changes.

Some enterprises produce metal supports for pipes in polyurethane foam that do not have an insulating layer. Their cost is lower than polyurethane foam supports, but they do not have the advantages that products with thermal insulation have:

• improved protection against moisture from the atmosphere and soil;
• high resistance to mechanical loads;
• protection of pipelines from minor changes in shape;
• chemically neutral, low flammability.

Polyurethane foam is suitable for insulating any material. It is suitable for concrete, glass, metal, wood, plastic, etc. It is not destroyed by temperature changes and retains its quality for decades. Those wishing to order high-quality polyurethane foam supports for pipeline construction, our company can always supply the required quantity. All products are certified, have a guarantee, and delivery is guaranteed

PPU pipeline supports: varieties

On the company's official website you can order all types of pipeline supports with polyurethane foam insulation. They can be divided into the following categories:

• fixed, ensuring rigid fixation of the pipe on the support, excluding any change in position in the horizontal and vertical position, can be mounted in reinforced concrete frames;
• sliding (movable), allowing the pipe to move along the support during its linear elongation, ensure uniform distribution of mechanical load and thermal deformation.

Sliding supports for pipes in PP insulation make it possible to partially dampen vibrations and maintain the integrity of the pipes in the event of ground subsidence and seismic tremors. The qualities of polyurethane foam are very important, allowing:

• provide high heat and sound insulation with high material density and elasticity and flexibility with low density;
• adjust the thickness of the material to better suit the climatic conditions of the area and the temperature of the transported medium.

The protective polyurethane foam layer can be double or single. Double protection improves the protective characteristics of the layer, reducing thermal deformation and heat loss. PPU insulation lasts for more than 30 years, maintaining its characteristics throughout its operation.

Production

To manufacture polyurethane foam supports for pipelines, hoists of different brands are used. The choice of material is influenced by the expected operating conditions and design documentation. Supports are required for laying cold water and heating water pipelines; they can be used when installing gas and oil pipelines.

The company produces 2 types of products:

• intended for laying PPU-PE pipes (used for underground installation, in a channelless manner);
• intended for installation of PPU-OTs pipelines (used for above-ground installation).

The products offered by the Spetsneftemash enterprise are suitable for laying PPU PE and OC pipes. They are manufactured in accordance with the requirements of GOST 30732.
