Stainless steel chimney inspection is a good habit for equipment maintenance, which can make the equipment work normally for a long time.

For example, if we were to insulate a stainless steel chimney, we could paint it, build platforms and hoops, or apply other lining coatings; or

To desulfurize the passing gas, a large desulfurization plant system needs to be built, which is made of corrosion-resistant high-alloy clad steel, stainless steel, and rubber; or the chimney is reinforced to make it durable. In some engineering buildings, due to construction quality, maintenance, design or fire, wind disaster, earthquake and other reasons, it is necessary to establish a large-scale desulfurization device system,

The stiffness and strength of stainless steel chimneys will be reduced, especially for some old buildings, it is necessary to carry out regular and timely inspection and reinforcement, and carbon fiber materials can be used to improve the bearing capacity of the mechanism.

The inspection of stainless steel chimney usually follows the following three steps

1. Basic inspection. The foundation of the stainless steel chimney is basically underground. The quality evaluation of stainless steel chimney foundation is mainly made of stainless steel

Uneven settlement and inclination of the chimneys were observed. Reinforced concrete chimneys are different from general frame structures. It is an independent cantilever member and belongs to high-rise buildings

structure. Therefore, it is very sensitive to uneven settlement and deformation of the foundation, and a small settlement can cause the stainless steel chimney to tilt seriously.

2. Check the upper cylinder structure. The inspection of the upper cylinder structure includes two parts: the concrete wall and the lining

The main inspection contents are as follows:

1). Strength test;

2). Overview of appearance defects;

3). Corrosion.

3. Inspection of auxiliary facilities. The inspection of auxiliary facilities mainly includes the integrity and corrosion of the ladder, the function of the lightning protection device, and the integrity and specification of the aviation signs.

Generally from the height of the stainless steel chimney, the rebound method and a measurement area are taken every 20 meters

Concrete chimney walls were strength tested and the chimney center cavity was patched with cement mortar.
