How to reduce a flange size while maintaining a consistent pipeline ID

Maxi stub flanges — comprising a hybrid stub flange and backing ring — are a quick and effective solution to reduce a flange size whilst keeping your HDPE pipeline internal diameter (ID) consistent. They’re particularly useful when your poly pipe system features a magnetic flow meter. That’s because maxi flange adaptors are specifically designed for …

Quick guide: Poly Buttwelding Parameter Calculator (Single Low Pressure)

Buttwelding is the most common type of welding process used to join High-Density Polyethylene (HDPE) pipes and fittings. The process involves the joining of two plain ends together, using high temperatures and extreme pressure. HDPE buttwelding requires complicated formulas to work out the correct Heating and Pressure parameters. Each of these differ for every size …
