The pressure tank manhole used in the pharmaceutical and food industries are no longer sufficient for current needs, and there is a need to improve the use of sanitary stainless steel manhole.
Followings are characteristics of Likemetals sanitary stainless steel manhole:
1. The pressure is moderate, around 0.3MPa, and the highest pressure is 1.0MPa.
2. clean everywhere, even those areas out of sight. Easy to clean both inside and outside.
3. Sanitary manhole is light-weight, labor-saving and easy to use.
