2. Design the system with flexible and/or rigid couplings and allow the pipe to move in directions desired, with the use of an- chors and guides if so required. With this method, it is important to ensure that movement at branch connections, changes of di- rection, equipment hookup, for example, will not cause damage or harmful stresses.
3. Design the system with flexible couplings utilizing the expansion/contraction capabilities of these products. The following example illustrates this method:
•6-Inch, Schedule 40 Steel Pipe, Roll Grooved, 150 foot long, anchored at each end.
• Maximum Temperature = 200°F • Minimum Temperature = 40°F
• Install Temperature = 80°F
