KF chain clamps (HT)
KF chain clamps sizes: NW80...250
Chain clamps available in different materials.
Composite/stainless steel.strong enough to make good seal, but also soft enough not ot crack the glass flanges under temperature changes. Usable with polymer seals only. Work with glass and metal flanges.
Alu/Stainless steel or pure stainless steel: applicable for metal seals, providing sufficiently strong and uniform pressure over the flange diameter. Stainless steel chainclamps are imperative for metal seals and pressure applications.
