High-Pressure Temperature, Maintenance-Free Rotary Compensator Specialised Pipe And Fittings


Maintenance-free rotary compensator and rotary compensator products are all sealed by the flexible packing in the packing cavity. During the use of the product, the packing will wear a little every time it rotates. When the wear amount reaches a certain value, the product will leak. The maintenance-free rotary compensator adds a set of springs above the packing compression flange. When the packing shows a small amount of wear, the tension of the compression spring is used to compensate, thereby prolonging the leakage time of the product (the leakage time is delayed by 3-5 years ). When the amount of wear exceeds the amount of spring tension compensation, you only need to tighten the nut above the spring compression flange. There is no need to stop the gas for repair, there is no limit on the number of operations, and it is not easy to leak, thus greatly improving the gas supply unit and gas consumption The social and economic benefits of the unit. The product compensates 5000 times under the pressure of 4.0Mpa without leakage, and the sealing effect is superior



The sealing packing of the maintenance-free rotary compensator is resistant to temperature from -60°C to 800°C. Because the outer sleeve of the compensator and the inner sleeve of the outer sleeve are welded with retaining rings, the two retaining rings are installed between the two retaining rings to reduce friction. (Rolling ring) The ball reduces the wear of the inner sleeve to the sealing packing. And because the natural tension of multiple sets of springs on the compensator device pushes the packing gland flange, the extremely slightly worn packing is always in a compact state, so that the liquid or gas medium in the pipeline does not leak. When the packing is worn When the amount is large, the spring tension cannot be adjusted. External force can be used to adjust the spring compression so as to achieve the required sealing effect without stopping the work. Therefore, this product overcomes the shortcomings of other similar products. The original rotary and sleeve The tubular compensator cannot be compensated and adjusted in time after the packing is worn, which leads to the deterioration of the sealing performance of the compensator until leakage occurs, and the product must be removed from the pipeline to open the supplementary packing after the packing is worn out, which affects the operation of the pipeline. The normal production of users.

Material used

The sealing packing selected for the maintenance-free rotary compensator is all flexible graphite, with a temperature resistance of -60℃-800℃, and the grades used are nuclear grade, industrial precision grade and maintenance-free.



The maintenance-free rotary compensator uses a press to mold the sealing material first, and the molding requires less dense density and maintain plasticity. Then put the N ring of the packing ring (determined according to the product requirements) into the packing cavity, add some ingredients that delay oxidation, and then perform secondary molding under a certain pressure by a hydraulic press (the hydraulic press exceeds the manual wrench process in terms of strength and uniformity) , So that the packing rings are integrated, so as to increase the density of the packing, make the sealing performance of the packing better, and prevent the product from leaking.

The maintenance-free compensator uses the same diameter as the inner tube and the reducing tube, so that the medium can flow smoothly, and solve the above problems. Some similar products adopt reducing pipes, which make the medium produced by reducing the diameter of the product vortex, and generate flow resistance, which makes the pressure loss of the medium large and slow down the flow rate.


Expansion Joint Bellows Compensator is made of SUS304 material, multiply bellows with features of lower elasticity coefficient, high-temperature and high-pressure resisiting, applied to absorb the expansion or copression of the HTM fluid pipeline. It can make a long service life in piping system.
