The all new range of KRAIS O.D. clamp bevelling machines and ID. clamp SFSF split frame clamshells delivers maximum power and performance for fast, accurate weld preps on pipes and tubes ranging from V2” I.D. up to 36” 0.0. (12,7 - 914 mm) for ID. clamp machines and from 2" up to 48” (60-1220 mm)
for 0.0. clamp machines depending on the model and configuration.
Cutting, facing, bevelling and counter boring preparations are possible on all machinable alloys including stainless steel, duplex, super duplex, inconel and other alloys.
Seal and strength weld removal applications for heat exchangers and boilers are the primary focus of our machining technology. The rugged design features a selfaccepting torque system with self-centering inner clamping which allows one skilled operator to make end preps quickly and safely, avoiding the slow and arduous process of grinding. The in-house manufactured pneumatic drives are resilient and powerful. The carefully selected quality eu ropean bearings ensure great support to the drive shaft, right angle gear assembly and cutter head. This provides rigidity and unparalleled stability.
