Parallel scratchier

SCITEQ’s high accuracy parallel scratchier is for marking pipes around the circumference before carrying out longitudinal (heat) reversion tests. Both a table model and a portable model available. Further, a table model for inside marking of corrugated/rib pipes available.

Description

The unit is produced as a model for outside marking of samples, with a distance between the pins of 100mm, and alternatively with 3 pins, each with 100 mm between the pins, to ensure higher measuring accuracy. The standard model covers pipes with OD Ø40mm to Ø630mm.

The unit is also produced as one to make markings on the inside diameter of pipes. This unit is especially intended for corrugated and Rib/Ultrarib pipes where an outside marking is not possible.

The pipe sample is cut in a length to perform the parallel markings. Thereafter it is placed on the Vblock against the stop rollers. A contra weight on the marking pins makes sure that the sample is cut deep enough for clear visible markings, while rotating the sample manually on the V-block.  SCITEQ also produces a portable parallel scratchier. The unit is produced as a model for outside marking of samples, with a distance between the pins of 100mm. The unit can be used on pipes with an outside diameter from 200mm and larger.
