External inspection and internal inspection of stainless steel reactor

- Jun 27, 2018 -

In the work process of the stainless steel reactor, the first thing we need to do is to conduct a comprehensive inspection of the product, so that it can effectively avoid the problem of its use after installation of the equipment to a certain extent. To a certain extent, the inspection of the quality of its stainless steel reactors mainly includes external inspections, internal and external inspections, and comprehensive inspections.

External inspection of stainless steel reactor

The external inspection of the stainless steel reactor is mainly to see if there are abnormal phenomena such as deformation, leakage, and cracks on the surface of the outside of the kettle. When the operation is performed, the safety accessories are complete, and they are reliable and sensitive during operation. And whether the fastening bolts are fully and tightly tightened, and whether the foundation has any abnormal phenomena such as sinking, tilting, and corrosion protection. The inspection personnel's work is mainly responsible for the external inspection of the stainless steel reactor, and it is also a part of the operator's touring inspection and daily inspection. External inspections by container inspection personnel should be conducted at least once a year.

Stainless steel reactor internal and external inspection

Stainless steel reactor inside and outside the surface of the wear and corrosion, etc., in the operation can use the magnifying glass or the naked eye of all welds and head over the area and other stress concentration components for effective inspection, to some extent, it is necessary The ultrasonic or ray detection can be used to check the internal quality of the weld; when measuring the wall thickness, if the measured wall thickness is smaller than the minimum wall thickness of the container, the metallographic examination should be performed again.

Full inspection of stainless steel reactor

In addition to external inspections and internal inspections, stainless steel reactors are also required to perform pressure tests when they are used. To a certain extent, they will be determined based on the characteristics of their reactors. The extent of the need for non-destructive testing of welds and spot checks or the inspection of all welds. For reactors with low pressure, non-flammable, non-toxic, non-corrosive media, if no defects are found, after a certain period of use and inspection, non-destructive inspections may be omitted.
