PVC-O pipe pushes diameter records

Molecor, a specialist group in PVC-O technology for pipe extruders, is showing its integrated Seal System (ISS+) as well as new technology to manufacture large diameter PVC-O pipes up to DN 800 mm.

The first PVC-O pipe manufactured with Molecor’s patented technology was produced in 2007, just in time to be shown at K 2007. This first tube was a DN 200mm. In 2008 the range increased to DN400mm, which Molecor claims was the “unofficial limit” for PVC-O pipes at the time.

By 2010 the group was able to manufacture tubes with diameters of 450-500mm. The group marketed this at K 2010 as “the biggest PVC-O pipe in the world”.

Now, in 2013, the group claims that its technology is ready to reach the DN 800mm mark for PVC-O pipes.

The manufacturing concept uses an air-based technology in which no water is involved, which reportedly makes a safer, cleaner, more efficient and profitable process. It is a flexible system able to work continuously with an extrusion line, or it can operate in batches.

The new integrated seal system (ISS+) is one of the more recent technological developments.

This system, patent pending, is designed to manufacture socketed oriented pipes with automated integration of the gasket, retaining the orientation degree in the critical areas of the pipe.
