PTFE Convolutions Flanges Standard flanges are available in compliance to the international piping standards ASME Class 150/300 and DIN PN 10/16. Special flanges on request. The flanges are carefully machined and an internal flange profiling is provided. This enables an optimal placement of the first and last convolution of the PTFE bellow in both flanges. The risk for cracks in the bellow is therefore nearly non-existent. Flanges are available in the following materials: GGG 40.3 - 0.7043 * (standard) St 52.3 - 1.0570 * SS 304 - 1.4301 SS 316 - 1.4401 SS 316 L - 1.4404 SS 316 Ti - 1.4571...

Bellow Material Limit Sleeves In its standard design the bellow is made from prime multi-laminated virgin PTFE material. This lamination reduces the material’s permeability to an absolute minimum and allows for an exceptional resistance to stress-cracking. Limit sleeves prevent damage to the convolutions by preventing the bellows from being compressed below the permitted minimum axial length. If the bellows are applied in application which involve the handling of media at high velocities or with entrained solids using PTFE sleeves is advised. In extruded PTFE bellows plasticizers are most...

Vanéflon Industrieterrein Zwaarveld 12 9220 Hamme, België Tel.: +32 (0)52 47 63 99 info@vaneflon.be www.vaneflon.be PTFE Expansion Joints PTFE expansion joints are essential in most piping systems demanding high resistance to chemicals and temperatures. They are designed to absorb and compensate for heat-induced expansion and contraction thus protecting the pipes and any sensitive equipment attached. The expansion joint’s ability to absorb movement is determined by the number of convolutions and the thickness of the PTFE bellow. The higher the number of convolutions, the higher the ability...
