The tension bar type corrugated expansion joint is made up of two bellows, long intermediate nozzle and large pull rod. It is widely used in oil, chemical, steel, metallurgy, machinery, transportation, transportation, ship, wharf, construction, rubber, paper, textile, electric power heat network, pharmaceutical, medical treatment and other industries. It can absorb lateral displacement in any plane of pipe system. When moving, the spherical nut on the big pull rod moves around the spherical washer, and the big pull rod also has the ability to withstand the internal pressure thrust of you.
Note on the installation of pull rod type corrugated expansion joint:
1. The small rod on the bellows expansion joint is used for the installation of "cold tightness". It can not be used as a bearing part. After the product is installed on the pipe, it must be dismantled so that it can be put into operation.
2. When the lateral displacement of the bellows expansion joint is higher or the pressure of the system is higher, it can be "cold" for the bellows expansion joint, and the cold tightness is half of the actual lateral displacement, that is, 1/2Y. The direction of cold tightening is opposite to the direction of lateral displacement.
