Porcelain surface protection during the installation process of enamel glass equipment

Abstract:

When constructing and welding near the enamel equipment, care should be paid to covering the pipe mouth to prevent external hard objects or welding slag from damaging the porcelain layer; personnel entering the tank to inspect and install accessories should wear soft soles or cloth sole shoes (it is strictly forbidden to carry hard objects such as metals with them). The bottom of the tank should be covered with enough cushions, and the cushions should be clean and the area should be large enough.

1.When constructing and welding near the enamel glass equipment, care should be paid to cover the pipe mouth to prevent external hard objects or welding slag from damaging the porcelain layer;

2.Personnel entering the tank to inspect and install accessories should wear soft soles or cloth soles (it is strictly forbidden to carry hard objects such as metals with them). The bottom of the tank should be covered with enough cushions, and the cushions should be clean and the area should be large enough.

3. Glass enamel equipment with porcelain layers is not allowed to be welded on the outer wall; when welding on a jacket without porcelain layer, measures must be taken to protect the steel plate with porcelain layer. The adjacent part of the welding should not be overheated locally. Protection measures include not cutting and welding with oxygen. When cutting the opening, the inside of the jacket should be watered. When the welding port is close to the upper and lower rings, the internal porcelain surface should be evenly preheated and welded with interval intermittent welding.
