How much do you know about the type of heating pipe compensator?
Corrugated compensator is generally used in the pipeline with pressure, so it is required to be able to accept a large pressure greater than the planning of the medium in the pipeline, therefore, the product manufacturers are distinguished in accordance with the different pressure levels of various standards for production, the use of various parameters based on the planning for selection. Compensation amount. The compensation amount of corrugated compensator is its ability to compensate for the large deformation of the pipe stretching, tightening, bending and other combinations of deformation, according to the different varieties of compensators, can be divided into axial compensation amount, lateral compensation amount, angular compensation amount and composite compensation amount. Temperature is the main reason that affects the amount of compensation.
Bellows compensator is an axial bellows compensation device controlled by multi-layer or single layer thin-walled metal. It is an axial bellows compensator commonly used on heating pipes. This compensator is small in size, light in weight, occupies little space, easy to install and convenient to install. Bellows compensation has excellent sealing function, no need to stop maintenance, high pressure talent and task temperature, but small compensation talent and high price. In order to make the axial bellows compensator strictly in accordance with the axial thermal expansion or cold contraction of the pipeline, the compensator should be set near the fixed bracket with guide bracket. All guide brackets should be used to control lateral displacement and prevent longitudinal deformation of the pipe. Commonly used axial bellows compensators are usually used as standard pipe accessories and are connected to the pipe by flanges or welds.
The square compensator is a U-shaped compensator consisting of four 90° seamless steel pipe bends or mechanism bends, which rely on the deformation of the bends to compensate for the thermal elongation of the pipe section. Square compensator is easy to produce, does not require regular maintenance, compensation talent, small fixed point thrust (i.e. compensator elasticity), can be used for a variety of pressure and temperature conditions, the disadvantage is that the compensator appearance size is large, accounting for air accumulation. In order to improve the compensation talent of the compensator (or increase its displacement), usually using the pre-cold drawing method, the common pre-stretching amount of fifty percent of the elongation of the pipe. In some cases, its compensation capacity is twice as much as when there is no pre-stretching. It is a line calculation chart for calculating the steel square compensator. The sleeve compensator consists of a packing-sealed casing and a housing tube. The two work in unison to compensate axially. There are two methods: one-way and two-way. The sleeve is sealed with a packing ring between the sleeve and the casing. The packing is pressed tightly between the end ring and the gland to ensure a tight seal. The packing is made of asbestos-clamped copper wire root. When replacing the packing, the gland should be loosened to facilitate maintenance. The compensation capacity of the sleeve compensator is New Year's Eve. Commonly up to 250 ~ 400mm, small footprint, small resistance to media activity, low cost. It is practical for the task pressure is less than or equal to 1.6mpa, the task temperature is less than 300 ℃ on the pipeline. The compensator is welded to the pipeline.
