Procedure

Matrix Elements are normally supplied in continuous lengths of up to 6 metres.  For longer tubes separate elements can be joined and installed in series.

hiTRAN Matrix Elements are bespoke to each customer and can be designed to fit tube diameters from 4mm to 150mm.

To ensure optimum performance the Matrix Elements are normally installed in the direction of fluid flow within the tube.  Wherever access permits, the Matrix Elements are pulled into the tube.

Matrix Elements are secured at the end of the tubes using the hiTRAN  ‘Key Link’ system, or by joining the element centre cores together, across the tube plate.  The retaining systems used are very robust and designed to keep the elements in place under all flow conditions.

Full instructions and diagrams are provided for installation, with the necessary securing wires, joining fittings and securing rods.
