Introduction to jdh type large pull rod transverse ripple compensator
Instructions for use of JDH type large pull rod transverse ripple compensator: The large pull rod transverse ripple compensator can compensate for the lateral displacement and small angular displacement of bent pipe sections, and is usually not used to compensate for angular displacement.

Calculation of the force exerted on the support by the large pull rod transverse ripple compensator:
Lateral elasticity: Fy=Ky · Y Bending moment: M=Fy · L
In the formula: Ky - lateral stiffness N/mm Y - actual lateral displacement (deformation) mm
The distance m from the L-pipe bracket to the midpoint of the compensator.
Application example of large pull rod lateral ripple compensator (without considering the correction of temperature on compensation amount and stiffness)
A certain carbon steel pipeline has a nominal diameter of 500mm, a working pressure of 0.6MPa, a medium temperature of 350 ℃, a lower environment temperature of -10 ℃, and a compensator installation temperature of 20 ℃. According to the pipeline layout (as shown in the figure), a large pull rod horizontal compensator needs to be installed to compensate for the lateral displacement of AB pipeline section 160mm. The number of fatigue failures of the compensator is considered as 15000 times, and the force on the support AC is calculated.
Solution: (1) According to the lateral displacement of AB pipe section
Y=160mm, the sample can be selected as 0.6DLB500-FB-2000, with lateral compensation Y0=193mm and lateral stiffness Ky=22N/mm
(2) Calculation of force on supports A and C
When calculating, consider cold tightening and the amount of cold tightening can be taken as half of the actual compensation amount, which is 1/2Y. FA=Ky·160/2=22 × 80=1760(N) MA=FA × 2=1760 × 2=3520（N·m）
FB=Ky·160/2=22 × 80=1760(N) MB=FB × 2=1760 × 2=3520（N·m）
Namely, supports A and C bear a thrust of 1760 Newton and a force distance of 3520 Newton meters, respectively.
Application of jdh type large pull rod transverse ripple compensator
The compensator consists of connecting pipes, two corrugated pipes, and large pull rods. The spherical nut rotates around the spherical washer, and the pull rod also has the ability to withstand internal pressure and thrust. The compensator consists of two corrugated pipes, a long intermediate connecting pipe, and a large pull rod, which can absorb the lateral displacement of the pipeline system. The product is suitable for transporting seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, finished oil, air, gas, steam and particulate powder with a temperature not exceeding 250 degrees Celsius. Able to achieve lateral and angular displacement of pipelines. Able to absorb the internal pressure and thrust of the pipeline. Stable operation and long service life.
