Difficulties in Corrugated Metal Bellows

Whether it is the Corrugated Metal Bellows of the heat exchanger used in the energy-saving water dispenser, or the condensing coil of the water heater and the stainless steel Corrugated Metal Bellows of the air energy, the lengths are relatively long, and the commonly used specifications are 10cm - 150mm, the bellows The longer the length, the harder it is to make, why is that?

Corrugated Metal Bellows

Wall thickness of Corrugated Metal Bellows: The thickness of the standard specification is determined, and the wall thickness of the long pipe must be thicker than the standard specification, the pressure will be higher, and the safety performance will be better.

Outer diameter of Corrugated Metal Bellows: The metal bellows has been welded, wave-formed and polished, etc. The longer the bellows is, the longer the bellows will appear, the local irregularities will appear, and the diameter will become larger; so the longer the bellows, the higher the requirements.

The diameter of the stainless steel Corrugated Metal Bellows of the air energy is larger than that of the energy-saving water dispenser, the pipe wall is thicker, and the pressure resistance performance must be good.

Therefore, the generally common Corrugated Metal Bellows long tube is harder than the standard metal bellows, mainly due to the difference in wall thickness, and the long tube has a larger and wider range of uses.
