Supplementary technologies used in emergencies during repairs and modernization projects

Rebuilding ligaments in tube sheets

When there are few (up to 8%) damaged ligaments in the tube sheet, caused by excessive corrosion, it is economically justified to rebuild them. Such defects are often seen on tube sheets of turbine condensers on the side of the cooling water outlet

Enlarging the diameter of holes in tube sheets and partitions

When modernizing exchangers (e.g. by enlarging the diameter of the tube on the outside of the bank to eliminate tube vibrations), the diameters of the holes in the tube sheet are often enlarged. This procedure is performed with a special tool with calibrating blades.
