Industrial PTFE expansion joints are manufactured of unreinforced molded PTFE bellows and are standard with ANSI 150# ductile iron drilled flanges with stainless steel reinforcing rings and limit bolts (pre-set from factory). These expansion joints are available in 2, 3, or 5 convolutions with various allowable movements as noted below (also often referred to as couplings for 2-convolutions, expansion joints for 3-convolutions, and bellows for 5-convolutions, respectively).
