Straight-Tube Heat Exchanger baelz 111 / baelz 112
●
Removable head covers enable both ends of each tube to be inspected and repaired. In the case of
leaking tube connections, it may suffice to rework the tube sheet connection with a special mandrel.
However, it is more practical to drive in a guide bushing or a plug.
●
Pipe openings can be sealed by shutting down the affected heating pipe using blind plugs.
Take care when tightening the flange couplings! Observe the following remarks.
Beware
● Tighten the flange screws crosswise and particularly evenly. Too forceful and uneven retightening distorts
the flanges and leads to permanent leakage. Tightening too tightly can also cause the seals to flow.
Always observe the permissible surface pressure of the seals. Use a torque wrench and ensure that the
thread runs smoothly by applying heat-resistant lubricant on clean screws. Please refer to the Baelz data
sheet DS 80900...81100 for tightening torques depending on screw size and material.
