Device for interior scalping of pipes, particularly pipes with inner diameter smaller than certain millimeter, comprises scalping head with variable diameter, where scalping head comprises hydraulic and extendable cutting plate

摘要

The device comprises a scalping head (10) with variable diameter. The scalping head comprises a hydraulic and extendable cutting plate (16). The scalping head comprises a cutting plate holder (18) for holding the cutting plate. The cutting plate and the cutting plate holder form an alignment system, to position the cutting plate at the cutting plate holder in a repeatable manner. An independent claim is also included for a method for interior scalping of pipes, particularly pipes with an inner diameter smaller than certain millimeter.
