Stainless steel lined PTFE corrugated expansion joint

The stainless steel-lined tetrafluoroethylene corrugated expansion joint adopts a thin-walled multi-layer structure, which is flexible and low in rigidity. The product adopts a flanging structure, no circumferential weld, corrosion resistance, high temperature resistance, aging resistance, no leakage, long service life, Toxic, can be used in drinking water pipelines.

Stainless steel corrugated expansion joints have various structures such as axial, transverse, rectangular, circular, internal pressure, external pressure, single, duplex, tie rod, and direct buried types.

1. Structure and material:

1. Bellows: stainless steel 304, 316L, 321, etc.

2. Flange, connection: carbon steel, stainless steel 304, 316L, 321, etc.

3. Tie rod bolts and nuts: carbon steel, stainless steel

2. Notes for installation of stainless steel lined PTFE corrugated expansion joints:

1. The other end of the compensator on the pipeline far from the vibration source should be effectively fixed so that the compensator can isolate and absorb vibration.

2. The bellows should be effectively protected during electric welding operations at the construction site to prevent welding slag from splattering the bellows.

3. The compensator must be installed in a straight line without bending or translation.

4. When the compensator is used to compensate the displacement of the pipeline, the two ends of the compensator should be reasonably equipped with guiding supports.

5. The product is a non-constrained structure, and the fixing brackets at both ends of the product must be able to withstand the internal pressure thrust.

3. Main connection size:
