Column components are extensively used in the chemical, pharmaceutical and allied industries together with other applications such as food and drink production, dye works and electroplating.
This is because of the special properties of borosilicate glass 3.3 and PTFE together with the special materials that are used in some instances for internals, plus the fact that borosilicate glass 3.3 is an approved and proven material of construction for pressure vessels.
All column sections are supplied complete with support. The packing must be ordered separately. On special request column sections can be supplied without the packing support. Column sections and pipe sections may be used for the construction of columns of all nominal bores provided that the weight of the packing and retained liquid does not exceed the load-bearing capacity of the support. Column section can also be provided with a thermometer branch below the packing support.
Standard packing support for columns DN 80 to DN 300 is manufactured from borosilicate glass. From DN 400 and above, a combination of glass and PTFE is used for it is construction, thus maintaining maximum resistance to corrosion. There are two types of packing supports, Type A and Type B. Type A are made of fused glass rods and Type B (heavy duty) are made of glass plates, vertically arranged and tied with PTFE tie rods.
Other column accessories such as PTFE perforated plate, Column feed pipe, column feed sparger, spray feed pipe, column adaptor, reflux divider are also readily available in all sizes.
