The large tie rod transverse bellows expansion joint is composed of two bellows, long and medium indirect pipe and large tie rods. It is widely used in petroleum, chemical, steel, metallurgy, machinery, transportation, transportation, shipbuilding, dock, construction, rubber, papermaking, etc. Textile, electric heating network, pharmaceutical, medical and other industries. It absorbs lateral displacement in any plane of the tube. When moving, the spherical nut on the large rod moves around the spherical washer, and the large rod also has the ability to withstand the thrust of your internal pressure.
The large tie rod lateral bellows expansion joint can compensate the lateral displacement of the curved pipe section and the angular displacement of the small amount, and is usually not used to compensate the angular displacement.
The expansion joint is composed of a nozzle, two bellows, and a large tie rod. It absorbs lateral displacement in any plane of the tube. The displacement spherical nut rotates around the spherical washer, and the drawbar also has the ability to withstand internal pressure thrust. The expansion joint has two bellows, a long middle indirect pipe and a large tie rod, and the like, which can absorb the lateral displacement in any plane of the pipe system. The displacement spherical nut rotates around the spherical washer, and the drawbar also has the ability to withstand internal pressure thrust.
Connection method: 1. Flange connection type 2. Connection connection type
Installation notes for large tie rod lateral bellows expansion joints:
1. The small tie rod on the bellows expansion joint is used for installation and transportation of “cold tightness”. It cannot be used as a bearing member. After the product is installed on the pipeline, it must be removed before it can be put into operation.
2. When the lateral displacement of the bellows expansion joint is required to be large or the system pressure is high, the bellows expansion joint can be “cold tight”, and the cold tightness is half of the actual lateral displacement, ie 1/2Y. The cold tight direction is opposite to the lateral displacement direction.
