PTFE bellows expansion joint is partly made from PTFE, it has the properties of good chemical stability, corrosion resistance and is suitable for various kinds of pipe connection.
DESCRIPTION

Rectangular expansion joint is a compensation element, mainly used to compensate for the axial displacement of the pipeline and a small amount of lateral displacement, shock and noise absorption, with the advantages of simple design, easy installation, low cost. It is widely used in electric power, petroleum, chemical, transportation and atomic energy industry and other fields.


Rectangular expansion joint has following features: Strong resistance to external pressure; Low cost; Convenient construction; The resistance coefficient is small, large flow; Low temperature impact resistance; Good chemical stability; Long service life; Excellent wear resistance; Super compensation function.
