What that means in practice

PE80 rather than PE100, and that is a choice rather than an older product — the lower rating comes with flexibility and coilability, which is what long coiled runs need and rigid stick pipe does not.

What to check before buying BorSafe ME3440

• The classification is the specification: PE80, PE100 or PE100-RC, with the MRS figure attached. Two grades whose codes differ by one letter can be rated differently — BorSafe HE3490-LS is MRS 11.2 and HE3490-LS-H is MRS 10.0, and nothing on the sack will remind you.
• Colour is not cosmetic on pipe compound. Black is water and general pressure; orange and yellow mean gas across most of Europe. The wrong colour passes every mechanical test and fails inspection on site.
• For black grades, ask for the carbon black content and dispersion on the batch. That is what carries the UV life, and it is a batch property rather than something the grade name guarantees.
• If it is offered as off-spec or reprocessed, ask precisely what the deviation is. A compound that no longer meets its MRS rating is no longer the material the code names, whatever the paperwork says.
