Sliding saddles for PUF pipes
Main heating and water supply lines are an unstable system, exposed to temperature variations and irregularities of the transported medium flow during its service life. As a result of the continuous stress, the line’s parts are displaced from its center line. Sliding saddles protect the pipeline from uneven load distribution and vibrations, and ensure that the network components remain in a stable position.
Sliding saddles are installed as described in subclause 10.5 of SNiP 41-02-2003, at the specified intervals between them. The mounting interval is determined individually at each section of the pipeline and depends on the pipeline diameter and the type of utility. This arrangement provides for the uniform distribution of weight load, allows for the pipeline movement when exposed to temperature (observed with a substantial temperature difference between the location environment ant the heat carrier) in the specified direction. The saddles are designed to support pipes of any diameter, to provide vertical support, and to prevent mechanical wear of the thermal insulation coating.
All the material used to manufacture the supports is subjected to incoming inspection.
A sliding saddle consists of:
- Steel base.
- Holder. The round shape prevents damage to the PUF insulation layer.
- Clamps, fastening elements.
- Rubber gaskets (in certain cases).
The holder is rigidly fixed to the base by welding. The clamp presses the pipe to the saddle. The fastening strength is adjusted using the bolt and nut. The rubber gasket protects the external shell of the pipe from abrasion due to loads and deformation.
We offer three types of supports:
- Sliding saddles (GOST 30732-2020);
- Sliding saddles 313.ТС.008;
- Sliding saddles for installation in a casing.
The benefits of using sliding saddles are:
- Ease of installation. No special machinery or additional equipment is required.
- Multifunctional use. Applied for the laying of above-ground and underground utilities, vertical and horizontal sections.
- Reliability and resistance to wear.
- Strong fastening which at the same time maintains all the properties of the pipe insulating material.
