double tied expansion joint bellows apply in power station

Product description

Duplex tie rod type expansion joint (FL) is also called large tie rod transverse ripple compensator (expansion joint). It consists of two bellows and tie rods connected to the middle pipe, end plates, spherical and cone washers, etc.Expansion joint that is laterally displaced in the plane and can withstand the pressure and thrust of the bellows.

Description

1. After the compensator arrives, the following contents need to be checked out of the box:Documents: It is necessary to check whether the models, specifications and technical parameters listed on the compensator's label and certificate are consistent with the order contract, and whether other required auxiliary technical documents are complete.Appearance inspection: There should be no obvious scratches or sharp indentations on the compensator; there should be no foreign matter inside the compensator (wave trough); the connection port should be intact.Peel off, large drawbars, transport pullbars, and fasteners should be complete.

2. Precautions for lifting and transportation of compensator:When hoisting, special hoisting fixtures or lifting ears should be used. It is strictly forbidden to use transport rods as load-bearing components.The small-caliber compensator without lifting lugs can be tied to the takeover because of its light weight.During transportation and storage, prevent sun and rain, water immersion, and harmful gas corrosion.During transportation and storage, it is necessary to prevent falling and collision, and do not stack them with other items to avoid damage to the corrugated pipe.Bundles should be secured during transportation to prevent movement and rolling.

Ordering instructions

1. The material of the bellows depends on the characteristics of the medium and the temperature of the medium, and the material of the pipe and the pipe are the same.

2. Determine the displacement and pressure level of the expansion joint

3．Determine the connection type of the expansion joint, whether it is flange or welding

4．Determine the length of the product and the nominal diameter of the product
