What are the treatment methods for common faults of tetrafluoro corrugated pipelines?

Tetrafluoro bellows are deformed by bellows to relieve the pressure from the transport medium in the pipeline, as well as the expansion of the pipeline caused by the heat generated in the transportation process, which will affect the service life of the tetrafluoro bellows. Because now bellows are widely used in various fields, the gas pipeline is widely used in the family, which can effectively absorb the deformation of the gas pipeline when it is used.

Tetrafluoro bellows can be connected by tetrafluoro compensator. Generally, the connection modes can be divided into three types: two-end flange connection, one-end flange welding and two-end welding. The initial design of the pipe compensator for the inlet and outlet of each box body in the dry dust removal system of blast furnace gas is the connection of flanges at both ends. This method can not be successfully replaced when the compensator needs to be replaced after it is damaged. The connection mode of the latter is improved to one end flange connection and one end welding connection, although it can be replaced successfully. The installation of compensator is difficult, inefficient and high risk factor. The disadvantage of the installation method of flange connection at both ends is that in the field installation process, because of the different size of bolts and the different size of pre-tightening force, one end flange has been successfully installed, and the other end flange bolt hole is dislocated, so it can not be successfully installed.

Tetrafluoro bellows, as one of the measuring elements, are widely used in instruments and instruments. They can convert pressure into displacement or force and play an important role in measuring instruments. The allowable compression displacement of tetrafluoro bellows under compression state is larger than that under tension state. In general, the allowable compression displacement of the same material and specification bellows is 1.5 times that of the allowable tension displacement.

In the practical application of tetrafluoro bellows, some faults often occur due to improper operation of the constructors, which leads to the failure of the normal operation of the construction. It is really a headache for the businessmen. Tetrafluoro pipeline manufacturers will share with you the troubleshooting solutions of Tetrafluoro bellows in the construction process:

One kind: when the blockage occurs and the beam can not be pierced, the situation can be distinguished and treated.

For the deformation of the pipeline near the outer surface of the component, it is feasible to pick and chisel and re-drill. For the deformation of deep pipeline, the designer's opinion should be consulted for chiseling. If it cannot be repaired, it can be negotiated with the designer to enable the standby bundle.

Two kinds: corrugated pipe holes leak into cement slurry.

1. Unqualified corrugated pipe is used, because its strength is not up to the standard, the screw crimping joint is not firmly occluded, not tight, and there are holes or cracks in the joint.

2. The joint of bellows is not tightly sealed.
