What does it mean when one end of the waveform compensator is lined with a weld? Haven’t seen it
Thread Content
The end of the waveform compensator with a weld inside should be located at the medium inlet side in horizontal pipes. . . . . . If you’ve never seen it, how do you know how to understand it?
In addition to having several waveforms to account for thermal expansion and contraction, the waveform compensator also has an inner tube welded to its interior side (welded on only one side) in order to prevent an increase in fluid resistance as the fluid flows through it due to changes in the pipe shape (waves). The fluid should flow from one end of the weld to the other. The purpose is to reduce fluid resistance. You can look up information on compensators.
A wave compensator is used to prevent damage to pipes due to thermal expansion and contraction; it contains a straight tube with one end welded and the other end not welded, and the fluid enters from the welded end, primarily to reduce fluid resistance.
Another function of the lining is to prevent the accumulation of dirt from getting stuck in the gaps of the bellows
I disagree with the statement above. In addition to having several wave shapes to account for thermal expansion and contraction, wave compensators also have an inner tube welded to their interior side (welded on only one side) in order to prevent an increase in fluid resistance as the fluid flows through the area due to changes in the pipe shape (wave patterns). The fluid should flow from one end of the weld to the other. The purpose is to reduce fluid resistance. You can look up information on compensators.
