Process engineering for efficient plastics extrusion of tomorrow -From the raw material to the finished product Based on our modular line concept, we are able to implement cost-optimized and customer-specific solutions. This goes beyond the product specification to the processing of the materials, the infrastructure specified in the general conditions up to the appearance of the plant and the control interface. Our company takes all of these conditions into account when designing your extrusion line. We combine our own products with components from long term partners in order to supply our...

Complete lines for pipe extrusion – For stringent international quality standards Depending on the application, plastic pipes consist of a variety of different plastics. The main raw materials used are PO and PVC offering a multitude of advantages such as easy laying, installation and maintenance, light weight, resistance to chemicals, incrustation and corrosion, long lifetime and recyclability. Schematic overview of a standard pipe extrusion line rollStream / tiltStream: Roller tables or tilt tables for pipe diameters up to 3,500 mm pullStream: Haul-offs for pipe diameters from 5-3,500 mm...

Complete lines for pipe extrusion – Materials and processing – PVC PVC processing PVC is an extremely versatile material that is generally available as a dry (powder) blend. Prior to processing in the extruder, additives are blended into the virgin PVC in a heating/cooling mixing unit. PVC compounds are sensitive to shearing and high temperatures and are therefore gently processed on either parallel or conical twin screw extruders, depending on throughput requirements and pipe dimensions. battenfeld-cincinnati twin screw extruders • Longer, 34D processing unit battenfeld-cincinnati PVC...

Complete lines for pipe extrusion – Materials and processing – PO PO processing Polyolefin generally comes as a granulate. Since it is only moderately susceptible to shearing and thermal stress, it is particularly well suited for single screw extrusion. battenfeld-cincinnati’s PO tooling battenfeld-cincinnati offers spiral mandrel distributors and VSI pipe heads (patented combination of spiral mandrel distributor and lattice basket dies). All designed and manufactured in-house, which are specially suited for polyolefin processing. battenfeld-cincinnati single screw extruders • odular...

Complete lines for pipe extrusion – Pipe applications – Drinking water and gas gipes Drinking water pipes Pipelines made of plastic are found in the entire drinking water supply network. They have pipe dimensions up to 3500 DN and are used as supply pipes connecting water catchment areas with water treatment plants and drinking water reservoirs. They also serve as main distribution pipelines within the supply network. Plastic pipes with smaller diameters connect the water mains with the domestic supply lines, carrying drinking water to the end consumers. Drinking water pipes Page 6 – ©...

Complete lines for pipe extrusion – Pipe applications – Multi-layer pipes and cable ducts Multi-layer pipes for hot and cold water The term “domestic installations” covers a wide range of individual applications in buildings. These include all types of panel and underfloor heating systems, hot and cold water installations as well as sound-insulated drainage in buildings. Heating and hot water pipes must be resistant to internal pressure and highly heat-resistant. Pipes in heating systems must also be gas-tight, to prevent corrosion of the heating system’s metal components through oxygen...

District heating pipes District heating is defined as thermal energy transport from generator to consumer by an insulated pipeline network normally laid underground -mainly for central heating, but also for hot water supply in buildings. District heating is environment-friendly, since less CO2 and other exhaust gases harmful to the climate are released in producing energy. Plastic jacket pipes have a service life of more than 30 years and are resistant to chemicals and salts, physical impact and corrosion. They withstand operating pressures of up to 40 bar with water temperatures of up to...

Complete lines for pipe extrusion – Pipe applications – Sewage, drainage and mining pipes Sewage pipes In the past, cast iron or vitrified clay were used as raw material for sewage pipe systems. Now, depending on the application, plastics pressure and non-pressure solid wall, corrugated or multi-layer pipes are used. The preferred materials for public sewage systems (DN 200-800 and larger) are PE, PP or PVC pipes. Pipes used for domestic waste water disposal (DN 100-200) must be abrasion- and corrosion-resistant as well as resistant to domestic waste water and temperatures of up to 95°C....

Complete lines for pipe extrusion – Pipe applications – Drip irrigation Due to climate change and world population growth, water consumption for the irrigation of arable land will rise dramatically. Consequently, there will be a rising demand for irrigation systems that enable targeted water supply to plants even in regions with little rainfall. Drip irrigation Agricultural irrigation has been practiced for thousands of years, but drip irrigation systems have existed only for the last few decades. These systems basically consist of plastic pipes made of PE and fitted with outlets at regular...

Complete lines for pipe extrusion – PVC processing – 3-layer pipe extrusion line Multi-layer co-extrusion systems adapted to each particular application, available either with 3-layer tooling or as feedblock system, optimally adjusted for process engineering. 3-layer pipe system The most commonly used 3-layer pipe system is foam core pipe with a foamed middle layer. The foam layer enables a reduction of the total pipe weight by up to 25 %. Moreover, regrinds are very frequently used for the middle layer in both pipes with foam core and compact pipes. Fields of application 3-layer PVC pipes...
