The Lipp Dual-Seam digester System is provided as a completely leak proof sealed digester tank which is rapidly constructed onsite for the storage of various liquid and gaseous sub-straights substances; by utilizing this Lipp automatic tank construction manufacturing process, steel bands are double folded over at the edge, which interconnect them to form a dual seam spiral construction method. The unique design provides maximum tank integrity and clean joins so that even aggressive liquids in the digester tank interior find no attackable surfaces for corrosion, thus ensuring that maximum impermeability is achieved. This complete digester package is provided by the Lipp America team across the US and Canada.
