关于浓硫酸配套用材质的经验分享文：
sulfuric acid has become more problematic as the concentration of
the product has  exceeded 93%.  The source of the failure is not
poor material or the acid. In concentrations of 98.3% or higher,
sulfuric acid had a natural contaminant known as sulfur trioxide
(SO3). This has led to the new common terminology of 98+%
sulfuric acid. This high concentration acid sulfuric  attacks and
causes stress fractures in both PVDF . While PTFE is
chemically compatible its cold flow properties make it difficult to
seal at threaded connections. Alloy 20 is a bullet proof solution,
but is extremely expensive.

解决方案对于不同案例:
1)  for concentrations to 95% and 93℃
2) for concentrations to 95% and  80℃
3) for concentrations to 100% and 93℃
4) for concentrations to 100% and 150℃
