Instructions for installation and maintenance of sanitary manholes

The sanitary stainless steel manhole is located in the lower part of the tank, and the manhole is subjected to a large liquid pressure. In order to prevent leakage, the installation quality of the manhole must be strictly required. Sealed water lines are processed on the flanges and cover plates, and care should be taken during construction to avoid oil leakage during use. Mark each time you remove the manhole to avoid misalignment when reinstalling, which affects the tightness. When installing the nut on the manhole cover, apply even force to the opposite pairs to prevent oil leakage caused by deformation or uneven force of the cover.

The stainless steel atmospheric manhole is made of SUS304 and 316L, which can satisfy the food. It is produced in the pressure tank and the container has a top, and the way to the inside of the container is closed right. Withstand pressure up to 1000Kp (10bar).
