Wall-thickness and weight scanners are critical tools in modern pipe extrusion, ensuring pipe quality and saving material. They are part of material-saving technologies that directly reduce costs. 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, display the signal directly on the control screen, allowing operators to adjust settings easily. 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 operators by automating routine tasks 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 shorten equipment payback to less 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.
