Pumping up C-PVC production in India


Rajendra Industries, an Indian pipe extruder based in Rajkot, has commissioned a twin screw C-PVC pipe plant from Rajoo Bausano Extrusion (RBE). The Flomex RBMD- 66/30 line is being used to produce Rajendra’s ‘Kaizen’ brand of C-PVC plumbing pipes.


While C-PVC adds life to pipes, the material is difficult to process, says RBE. It says that its technology – built by RBE based on Bausano of Italy’s ‘Multidrive’ transmis- sion system – gives a huge advantage in terms of durability and extruder performance. To ensure flexibility in using


a range of raw material compounds, the plant is designed with a special screw profile and 30 L/D extruder. The patented multi-drive


system helps to boost production and eliminate torsional stress – resulting in a longer life for both gearbox and screw, as well as energy savings, according to the company.


RBE said the line could help


customers save up to 15 lakh rupees (around US$24,000) per year on power costs alone, due to its higher efficiency. Silicone oil circulation is


used to control screw tem- perature, resulting in better mechanical and physical properties of finished prod- ucts, said RBE.


Other benefits include: load


cell-based back pressure (for trial and testing of various


C-PVC compounds to achieve appropriate processing parameters); two vacuum chambers (saving time during cleaning); and an extended


length calibrator (for higher line speeds). “As we evaluated various


manufacturers of CPVC pipe plants, the relatively minimal power consumption -- and the flexibility to process a range of raw material compounds – was one of the key attributes in favour of Rajoo Bausano,” said Jaydeep Patel, director of Rajendra Industries. With an output of 220kg/hr, the machine is customised to suit Rajendra’s specific needs within C-PVC pipe manufacture. “We see this technologically


advanced plant being capable of meeting our needs of today and tomorrow,” he added. RBE is a joint venture


between Indian machinery manufacturer Rajoo Extrusion and Italy’s Bausano & Figli. ❙ www.rajoo.com ❙ www.bausano.com


Beer flowing in the pipeline


Drinkers in Bruges in Belgium may soon be enjoying their favourite tipple in very direct fashion – with critical help from plastic pipe. Local brewery De Halve Maan is


planning to build a beer pipeline as a way of preserving the city’s cobbled streets. It estimates that the pipeline will save around 500 lorry trips per year, and will allow it to continue production at its city centre site. Polyethylene pipes will transport


beer from the brewery to a bottling plant 3km away in less than 15 minutes – a rate of around 6000 litres/hour. ❙ www.halvemaan.be


6 PIPE & PROFILE EXTRUSION | January/February 2015 Conair


opens lab to test pipe


US-based ancillary equipment manufacturer Conair has opened a new lab for testing pipe extrusion lines.


The Conair Extrusion


Development & Testing Lab houses four production scale extruders and is staffed by three experi- enced full-time process engineers.


The 8,000-sq-ft (742-sq- m) lab, dedicated entirely to extrusion development and testing, will is situated at the company’s extrusion-equip- ment manufacturing facility in Pinconning, Michigan. In addition to conducting


FAT (Factory Authorised Testing) to confirm that a new extrusion line – com- prising an extruder, application-specific tooling, gauging and downstream equipment – can meet performance guarantees, it also conducts trials for extrusion companies. Conair’s extrusion


experts will help customers to perfect the line set-up of new products or experiment with new equipment or processing techniques to maximise productivity and profitability of existing product.


The manager of the new


lab is Dave Czarnik, a tooling expert who holds five extrusion-related patents and has worked in downstream extrusion for Conair for 21 years. ❙ www.conairgroup.com
