     Dongfang yoyik supply boiler part manhole HX4857

The boiler manhole is the hole that the maintenance personnel enters into the inside of the container during the maintenance or supervision of the boiler. It is to install, disassemble, clean and repair the internal equipment of the equipment. The structure of the hand hole and the manhole are basically the same, and a short tube section is covered with a blind plate. The diameter of the hand hole is generally 150~250mm. It should be convenient for the worker to wear gloves and hold the hand of the tool. The nominal diameter of the standardized hand hole is DN150 and DN250. When the diameter of the device exceeds 900 mm, a manhole should be opened.

 

Installation and maintenance

The 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 reloading, which affects the tightness.
