Calibration sleeves for producing PP-R pipes for example, Borealis RA 130 E.
This calibration system was specially developed as an alternative to disc calibration inserts. The G&G PP-R calibration sleeves are used in pipe production between 20 mm – 110 mm in diameter.
The intake area includes a slotted, adjustable, sealing water ring. In addition, the frontal area of the sleeve allows water to act as a lubricant, which results in an “indirect cooling” of the pipe. This is followed by the slotted vacuum calibration sleeve inside the vacuum tank.
Sleeves made out of bronze 500, housing out of Gunmetal (Red brass)
