Piping supports and suspensions
Piping supports and suspensions are parts intended for fixing and installing fixed piping. Poles are one of the basic elements present in almost all types of pipelines:
– gas pipelines;
– Engineering communications of the Khzhkh;
– industrial pipeline.
There are several types of supports, which are applied depending on the type of pipeline and the need to perceive the weight of the pipeline, or the fixation, or the free movement of the pipeline through the support platform.
Classification of supports:
– Movable supports (sliding, rolling, ball, spring, frontal guides). Movable supports supporting the pipeline system do not prevent the displacement of the pipes, contributing to the natural distribution of temperature deformations.
– Fixed supports (welded, collar, stout). Fixed piping supports are used for mounting above-ground and underground pipelines and are intended for the perception of vertical, horizontal, and vibration loads from pipelines.
Depending on the operating conditions, supports are made of different materials. In the temperate regions according to GOST 15150-69 the main material is carbon steel. In the case of the use of poles in cold climates according to GOST 15150-69, low-alloy structural steel is used.
There are a large number of normative documents (Series 5.903-13 Production of 8-95 Pipelines supports are movable, Series 5.903-13 Production of 7-95 Pipelines supports are stationary), on which supports and pipelines suspension are made. They usually specify the types of piping for which the supports are intended, the dimensions of the piping supports, the permissible loads for the supports, including the friction coefficients of the sliding supports.
