Semi-tube jacket
Thread Content
Sw6 half-pipe jackets are available in only three sizes; how should the dimensions of half-pipes in other sizes be calculated?
I also want to know; making it smaller doesn’t work either
If the coil diameter is greater than 150, it becomes a pressure vessel; an excessively large diameter results in low flow rates and poor heat exchange efficiency. If the diameter is too small, there are too many and too long welds, which is uneconomical; moreover, the shape cannot be large. So, the commonly used values are usually 60, 89, 114 (108).
This calculation method was developed with reference to foreign standards; those three specifications are clearly of imperial units, and no other specifications are listed in the foreign standards, so this functional module is rather useless
In fact, the semi-circular coiled tube does provide some reinforcement for the cylinder; the diameter of the coil is small and its thickness is quite sufficient, so safety is ensured under conditions of low pressure.
