Scanners for wall thickness and weight are critical tools in modern pipe extrusion for ensuring pipe quality and achieving material savings. They are part of material saving technologies that directly contribute to cost reduction. By enabling a close approach to the minimum required wall thickness and controlling pipe weight (low overweight), they optimize material usage.
In the past, specialized personnel like electricians were needed to interpret scanner signals. Modern electronic controls, however, make the signal visible directly on the control screen, allowing operators to easily adjust settings. This transformation empowers operators and removes previous frustrations.
Scanners provide real-time data crucial for process control. Combined with loss-in-weight gravimetrics and Automatic Temperature Centering (ATC), these Process Control Systems support the operator, automating routine jobs and ensuring the pipe is produced optimally.
The material savings achieved through precise control via scanners and gravimetrics are significant. Saving just 1-2% of dry blend can lead to a payback time for the equipment shorter than 1 year. Reducing overweight directly reduces material costs, contributing to the lowest cost price per pipe length. Scanners, along with gravimetrics and ATC, are essential components in modern pipe extrusion lines aiming for high reproducibility and low reject rates.
