JXH small pull rod axial corrugation compensator is also called expansion joint. This kind of compensator/expansion joint consists of two sections of bellows, medium-gold nozzle and small pull rod with limit nut. It absorbs transverse displacement as well as axial displacement. Small tie rods can not withstand internal pressure thrust. Notes for installation and use: 1. If the user does not need a small pull rod when using, please indicate when ordering. 2. If the user needs a small pull rod when using, the nut must be loosened after installation and a distance away from the ear plate (or support plate) (the value is determined by the axial compensation amount). 3. If the actual compensation measure is larger than the prescribed value on the sample (life N < 1000 times), then the small tie rod must be removed after installation. The transverse ripple compensator with large tie rod can compensate the transverse displacement of the bending section and the angular displacement with small value, which is not usually used to compensate the angular displacement. The compensator is composed of a nozzle, two bellows and a large tie rod. It can absorb transverse displacement in any plane of pipe system. The displacement spherical nut rotates around the earth surface washer, and the tie rod also has the ability to withstand internal pressure and thrust. JDH large rail transverse compensator/expansion joint is composed of two bellows, long middle pipe and large tie rod, which can absorb transverse displacement in any plane of pipe system. When displacement occurs, the spherical nut on the large tie rod rotates around the earth washer, and the large tie rod also has the ability to withstand internal pressure and thrust. Notes for installation and use: 1. The small tie rod on the expansion joint is used for installing and transporting "cold tightness", and can not be used as load-bearing parts. After the installation of the product on the pipeline, it must be removed before it can be put into operation. 2. When the lateral displacement of expansion joints is required to be large or the system pressure is high, the expansion joints can be "cold-tightened as much as half of the actual lateral displacement, and the direction of cold-tightening is opposite to the direction of lateral displacement". 3. During transportation and storage, it is necessary to prevent sunshine, rain, water immersion and harmful gas corrosion. 4. During transportation and storage, fall and collision should be avoided, and other articles should not be stacked together in order to avoid damaging bellows. 5. In the course of transportation, it is necessary to bind firmly to prevent movement and rolling. Opening inspection: Documentation: Check whether the models, specifications and technical parameters listed in the compensator's label, certificate of conformity are in accordance with the order contract, and whether other necessary ancillary technical documents are complete. B. Appearance inspection: Observe whether there are obvious scratches or sharp indentations on the compensator, and there are erroneous foreign bodies in the compensator (valley); the connection port should be intact.
