Molecular orientation in PVC pipes MOLECOR’S air-based technology supplies a highly stable and safe process, allowing the company to create a system able to manufacture PVC-O pipes up to diameters DN 800mm and PN 25 bar (M-OR-P 3180), covering a product range from DN 315mm to DN 800mm. This technology allows a high orientation degree, reports savings in raw material and is efficient and easy to use. increasing the range of DN and pressures, and claims to be the only supplier to offer the full range up to DN 800mm PVC-O pipe. The company’s R&D team has developed elbows, couplings, reducers and extensions – a wide range of fittings that are being validated during 2014 and will be available in 2015. Molecor PVC-O fitting

PVC-O fittings did not previously exist, and PVC-O lines had to be installed using either PVC-U fittings or ductile iron fittings. Molecor will offer a single plastic solution for water pipelines 100 per cent in PVC-O material, that can be used for irrigation, potable water transport, industrial applications, sewage, infrastructural and fire protection nets, among other applications.

The recognitions and awards received by the company include the ‘Innovation Gold’ prize received in the SolVinAwards 2013, in the category of innovation, the highest recognition of the event. Molecor has also actively participated in the creation of new standards throughout the world, and in the continuous update of current standards. The latest update to ISO 16422:2014, in which the product range has been extended from DN 630, the previous maximum in the 2006 edition, to DN 1,000mm, provides a new solution to

the market, where the trend is towards larger diameters. In addition to international standard ISO 16422:2014 are national standards in countries such as France, South Africa, Australia/New Zealand, UK and USA, and Molecor manufactures PVC-O pipes according to all these standards. The company, which recently expanded its production capacity up to 20,000t/year, develops advanced technology and products for molecular orientation applied to PVC pipes,

Extrusion technology for welding plastic pipes

blower, dual control of the temperature (blower/extruder), wide multifunction display for the setting and reading of the working temperature, high density LED to allow operation in spaces with reduced lighting, rotating lateral handgrip, power regulator, and safety power cut off system. The extruders may also be used in tight spaces, thanks to special shoes and continuous rotating 45° and 90° adapters. While the R-SB 20 and R-SB 30 models are compact and handy, the R-SB 40 is a powerful, versatile and flexible unit, with three different handgrips. The Stargun R-SB 50 model can be supplied with a special handgrip for geomembrane welding. All models can be provided with different types of handle, which allows customisation of the extruder.

welding of corrugated pipes. In order to do so, reliable precision tools are required, and this is the purpose for which the Stargun R-SB line was designed. The series is composed of four models, according to the amount of extruded wire – from 2.2kg/h in the smallest model, up to 5kg/h with the top line. All of the extruders have compact

RITMO SpA, a manufacturer of welding equipment for plastics, has renovated its extrusion line of manual welders and sheet welders for the fabrication of special pieces such as cisterns, air treatment towers and tanks. The technique is based on the application of fused (extruded) material, therefore allowing the fabrication of customised pieces, as well as the
