cut-to-length lines. The company’s lines are capable of producing pipe diameters from 8 to 660mm and wall thicknesses from 2.3 to 22mm. The 60mm tube welding line has won several domestic prizes. The company’s LWGC450 high precision cold roll forming line won the ‘China Innovation Prize for Cold Roll Forming Equipment’. In recent years the company has developed thick wall pipe welding equipment for the production of pipeline pipes, petroleum casing pipes and oil pipes. The pipe welding

lines are capable of handling steel grade X42- X70, J55 and N80-1 using flexible forming technology. These lines use PLC control to realise a high degree of automation, automatic parameter setting and production process automatic monitoring.

Maillefer’s drip irrigation lines include an entire series of innovations. More tube constructions and dripper types are available from the PIL extrusion lines. The fully integrated components include high performance dripper feeding and insertion, multi-layer extrusion and fully automatic non-stop coiling from the new KWI coiler. With the increasing demand from agriculture for ecological water irrigation systems, the drip irrigation extrusion lines are a smart response for tube manufacturers worldwide. In the area of heating and plumbing pipe are the new Maillefer forming and welding components used in manufacturing PEX- AL-PEX composite pipe. Features include easier forming tool setups, elimination of wear and dust from TIG grounding, and improved weld surveillance. Maillefer has undertaken the redesign of all the components on the PCL line, and the result is improved performance, efficiency, ease of operation and processing quality. Maillefer also presented its extrusion lines for blown fibre tubes and microducts, medical IV tubes, automotive fuel line tubes with six or more functional layers, and gas and water pipes. Highly engineered tube and pipe extrusion, such as large multi-layer flexible pipes for the subsea oil and gas industry, is the company’s speciality.
