TUBE TURNS' shows the way to eliminate equipment shutdowns In the past, directional changes in the tubes used in fuel economizers for boilers have been made with flanged Unbends or with header boxes. Although leakage was inevitable sooner or later, and repairs difficult, such conventional conncc* tions were necessary to permit periodic dismantling and mechanical cleaning. Now, improved methods of water treatment have.eliminated the need for such cleaning in most cases,'and with it, the need for faints that can be readily disassembled. Accordingly, Tubb Turns' Engineering Service has recommended re-fabri* eating tube assemblies with Tube-Turn 180 Welding Returns, which are available in. thick* nesses and radii to match the tube walls and centers of most economizers. The result has been the elimination of any leak* age in economizer tubing, thus ending shutdowns of economizers, boilers, and other critical equip* menr. In addition, pressure drop is reduced, and flow conditions improved. When you have a cough piping problem, bring it to Tubb Turns' Engineer* ing Service--a service that typifies Tube Turns' leadership in piping engineering. TUBE TURNS, INC., Dept.
