Blo-Line is Blotech’s own range of pneumatic conveyor pipe couplings, engineered for fast, secure and leak-tight connection of conveying pipework. Blo-Line pipe couplings provide a reliable seal under pressure, allow quick assembly and disassembly for maintenance, and are built to withstand the abrasive demands of bulk material conveying. The Blo-Line coupling range covers a full range of pipe diameters to suit dense-phase and lean-phase conveying systems alike.
