Our large acrylic tank sizes outer diameter from 90----1500mm. Wall thickness can be selected from 4mm to 110mm. They are made by mould of 2meters or 3meters long. Cast acrylic tube is more expensive than extruded tubing. Because the way cast pipe is manufactured which involved more labor. Then we adjust down to the exact inner and out diameters. After that, polishing clear perspex tubing to optical clarity.
