The key to plastocor® tube sheet cladding thick film coatings on tube sheets is a specially developed form plug system.

The plugs can have a conical (system 1) or radial (system 2) shape.

The plugs form the negative mold of the finished coating and are available in various sizes depending on the tubing involved.

system 1: conical shaped plugs

Conical tube inlet and outlet openings are formed for cylindrical tubes, with or without projection. This method is used in condensers since 1958.

system 2: radial shaped plugs

Radial tube inlet and outlet openings are formed for expanded tubes, with or without projection.
This method has been used in new installations since 1978.

example: retubing of titanium tubes of a Muntz metal tubes sheet

plastocor® tube sheet cladding system offers a complete encapsulation of the tube ends into the coating when retubing titanium tubes in a Muntz metal tube sheet or other difficult material combinations.

This provides additional safety for the tightness of the rolling area.
