Moving sliding supports, type T17.

Dielectric sliding supports type T17.00 are designed for fastening steel technological pipelines for various purposes with an outer diameter DN from 194 to 1420 mm.

They are made in accordance with TU-04698606-001-04 "Pipeline Support", series 4.903-10 release 5.

Engineering communications used to transport liquids and gases are subject to numerous loads. Only high-quality supports combining resistance to mechanical stress, temperature extremes, constant contact with atmospheric precipitation are capable of guaranteeing long service life of pipelines.

General characteristics

The main element of the sliding support is the channel, to which the supporting part with the sliding elements is attached. For fixing the pipe holders are provided with a semicircular shape. The support for the pipeline allows the line section to move relative to the axis, thus compensating for thermal expansion and soil displacement.

Depending on the design, the following types of supports are distinguished: 

  • Clamp on brackets. The main scope of application is the ground installation of utilities. In the clamp support, the pipe is held by a pair of elements that do not limit its longitudinal movement;
  • Compatible with land and underground communications. They have a cage with balls that allow the pipe to move not only in the longitudinal but also in the transverse direction;
  • These supports are used for pipelines laid inside tunnels. The design of the elements allows longitudinal displacement of the line, while the lateral movement is limited by stops;
  • Special support elements for regions with increased seismic activity. The yoke design, unlike the clamp structure, allows you to take on large loads. As a rule, they are installed on large pipe diameters.

Our company offers all types of supporting structures. The products comply with GOST and are popular among major national and private companies.
