MAILLEFER, which is exhibiting at Tube South East Asia, offers complete systems for multilayer composite pipe manufacturing and delivers lines for producing flexible corrugated or foam insulated composite pipes. The company claims that a composite pipe manufactured with a foam tube offers several advantages over a pipe insulated by the contractor at the building site. Both the foam tube and the composite pipe are fed to the line using two single payoffs. The coil length of the foam tube ranges from 700 to 1,200m with a diameter range of 28 to 46mm. An accumulator is used when switching from one empty payoff to the other full one. In parallel, the composite pipe is introduced from another pair of single payoffs. The pipe is either on coils or reels and diameters range from 16 to 26mm. The foam tube is applied around the pipe by first slicing it open lengthwise, then merging the pipe into the foam tube. The cut edges are then heated before being joined together

to form a welded seam. A compression phase maintains the edges perfectly aligned and holds the foam tube in place as the weld solidifies. Finally the product is ready to receive its outer jacket. The foam insulated pipe enters the extrusion head where a medium/high density PE layer ranging from 0.15 to 0.20mm uniformly seals the foam tube. The MXC extruder coupled with the most recent screw and barrel innovations offers a linear and homogenous melt across the full RPM range. The nearly finished pipe then enters a section of cooling water trough before reaching the conditioning components of the line. The Nomos ® PSU line control ensures a precise synchronisation of the various line operations at the highest possible speeds for the product.
