Vacuum sizing

As with pipe, siding manufacturing is highly optimized for efficient production at high rates and minimal costs. Siding uses powder compounds, twin-screw extmders, and vacuum sizing/cooling. [Pg.507]

The outside diameter of the pipe may be calibrated either by an internal air pressure of 1.3 to 2.0 bar, or by external calibration in a vacuum sizing tank (Fig. 6.17) operating at a pressure of 0.3 to 0.5 bar. For calibration by internal pressure, the diameter of the die ring is made approximately equal to the internal diameter of the finished pipe. For vacuum tank calibration, the die ring is made up to 25% larger and the haul-off is set for a wall thickness drawdown of up to 30%. [Pg.203]
