Rollepaal Launches Standardized Lines for Oriented PVC Pipe
System requires no specialty additives or complex line configurations to achieve orientation.
Rollepaal has introduced a standard extrusion line for oriented PVC pipe (PVC-O). The company says these lines are designed to meet the strict requirements of industry standards, such as ISO and the American Water Works Association (AWWA), and offer exceptional performance across a broad range of pipe sizes and specifications.
PVC-O pipes are known to provide more strength, durability and reduced material usage compared to traditional PVC pipes. However, Rollepaal notes that most competing systems require the use of specialized additives or complex line setups to achieve the molecular orientation necessary to produce PVC-O pipe. Rollepaal’s technology, on the other hand, reportedly enables manufacturers to use their standard PVC formulation, dramatically simplifying logistics, reducing the need for significant formulation changes and improving production scalability.
For ISO configurations, pipe sizes range from 90-630 mm in diameter, covering pressure classes from PN12.5 to PN25. The lines achieve outputs of up to 2,200 lbs/hr., even for the largest sizes. Similarly, AWWA lines deliver pipes with diameters ranging from 4-24 in., supporting pressure classes between 235 psi and 305 psi, and options for 165 psi applications.
