French manufacturer of HDPE and PP tanks
Stockage & Systèmes designs and manufactures storage tanks in HDPE (high-density polyethylene) and PP (polypropylene), in fusion-welded sheets or by solid helical extrusion winding. Around 300 tanks are delivered each year for corrosive liquids, concentrated acids, bases, chemical effluents and compatible food-grade liquids.
The choice of material and process depends on the stored product, the volume, the layout and regulatory constraints. After an on-site study, our teams guide you towards a single- or double-wall tank, vertical or horizontal.
Single or double wall
A single-wall tank is suitable for non-hazardous liquids; a retention bund is required for a polluting substance. The double wall / jacket / skin retains the liquid in the event of a leak, with detectors in the interstitial space — suited to acids, bases, fuels and fertilisers.
