3. Deterioration of the tube joint in service is instantly detected. 4. If the tube must be rerolled this can be done with high pressure on the joint yet both sides of the tube sheet are visible. 5. The Letect joint is structurally sound. or temperature.
The Letect joint can be used for any working pressure
6. The Letect joint can be used in floating head exchangers.
It is not a double tube sheet
The Letect joint is a new patented development of the C. H . Leach Company based upon 18 years' experience in the manufacture of heat exchangers for high pressure and temperature.

STEP UP PACKING RATE By applying high frequency vibration to packing operations, wo have succeeded in increasing the weight packed in the container and in eliminating degradation. Use of this Jeffrey-Traylor vibrating packer increases the density 30% over mechanically vibrated devices . . . decreases packing time up to 50%.
