Single- and Twin-Screw Lines for PVC and Polyolefin Pipes
New line produces pipe in a range of configurations for construction, other markets.
Bausano has launched its next generation twin-screw and single-screw extrusion lines for PVC and polyolefin (PO) pipe. Its twin-screw MD and single-screw E-GO ranges enables production of different types of pipes—rrigid or flexible, mono or multilayer, smooth or corrugated—for various applications, including construction, agriculture and medical.
Bausano’s twin-screw lines for PVC can accomodate pipe in diam. ranging between 63 mm and 160mm features. They feature the machine builder’s MD Nextmover 170/30 model, which is equipped with a double exit die head for overall production of more than 4400 lb/h6. On the machine, the gravimetric doser is designed to ensure maximum precision so the pipes in outfeed weigh the same. In addition, the 170/30 model features bimetallic screws and a cylinder that are subjected to less corrosion and wear.
Other innovative features include: stainless-steel cooling and calibration benches for producing pipes with a flawless surface; two 9-mm parallel calibration benches in a two-chamber configuration with temperature and water level control, which allows different vacuum conditions to be created as required; and a high-performance pipe cooling system that cools pipes more quickly, thereby improving their quality and taking up less space when installing the line. Bausano also offers end-of-line accessories, including a drive system, cutting unit and belling machine.
Energy efficiency improvements in the MD and single-screw E-GO ranges are powered by two innovative systems: Bausano’s Smart Energy System, with its electromagnetic induction principles that enables more rapid and uniform heating of the cylinder, for energy savings up to 35%; and its Digital Extruder Control 4.0, with a 21-in. screen, accurately monitors consumption of each single stage of the process and features a real-time display of performance for managing motor power, temperature, oil control unit inspection, screw adjustment and other parameters, on request.
Bausano’s extrusion lines also meet the Smart Factory vertical integration requirements and are able to communicate with third-party systems, such as the sophisticated in-line measurement tool for accurate control of the internal and external diameter and wall thickness of the pipe.
